First, interpretation is incremental, multi-level, and involves both general and task- and domain-specific knowledge. Second, generation is also incremental, proceeds in parallel with interpretation, and accounts for phenomena such as turn-taking, grounding and interruptions. Finally, the overall behavior of the system in the task at hand is determined by the (incremental) results of interpretation, the persistent goals and obligations of the system, and exogenous events of which it becomes aware. As a practical matter, the architecture supports a separation of responsibilities that enhances portability to new tasks and domains SN - 1-58113-325-1 UR - http://doi.acm.org/10.1145/359784.359822 ER - TY - JOUR ID - 130 T1 - Interruptive communication patterns in the intensive care unit ward round A1 - Alvarez,G.

VL - 74 IS - 10 N2 - OBJECTIVE: An exploratory study to examine interruptive communication patterns of healthcare staff within an intensive care unit (ICU) during ward rounds. METHODS: The study was conducted in a tertiary hospital in Sydney, Australia. Nine participants were observed individually, for a total of 24 h, using the communication observation method (COM). The amount of time spent in conversation, the number of conversation initiating and number of turn-taking interruptions were recorded. RESULTS: Participants averaged 75% [95% confidence interval 72.8-77.2] of their time in communication events during ward rounds. There were 345 conversation-initiating interruptions (C.I.I.) and 492 turn-taking interruptions (T.T.I.). C.I.I. accounted for 37% [95% CI 33.9-40.1] of total communication event time (5 h: 53 min). T.T.I. accounted for 5.3% of total communication event time (56 min). CONCLUSION: This is the first study to specifically examine turn-taking interruptions in a clinical setting. Staff in this intensive care unit spent the majority of their time in communication. Turn taking interruptions within conversations occurred at about the same frequency as conversation initiating interruptions, which have been the subject of earlier studies. These results suggest that the overall burden of interruptions in some settings may be significantly higher than previously suspected AD - The Centre of Health Informatics, University of New South Wales, NSW 2055, Australia. drgeorgealvarez@hotmail.com UR - PM:16024286 ER - TY - JOUR ID - 131 T1 - Interdisciplinary communication: an uncharted source of medical error?

Traditionally, the junior doctor and nurse act as `scribes' on the ward rounds, recording the outcomes in the multidisciplinary or separate medical and nursing notes. There are a number of ways in which this process can fail. First, the scribe may simply misunderstand the decision of the team, given the complexity and variety of decisions in a psychiatric setting. Second, the scribe may understand what to record, but what is written may be illegible. Finally, people present at the ward round can have different beliefs about what has been decided, but unless they immediately review what has been written, they may not realise the discrepancy. One or more of these failings can result in serious untoward incidents, such as a patient being allowed off the ward on unescorted leave when the responsible medical officer believed the team had decided against permitting such leave. It is only when there is a serious incident that discrepancies can and do emerge Y2 - 2005/05/01/ UR - 10.1192/pb.29.5.180 ER - TY - CONF ID - 57 T1 - Empirical development of a heuristic evaluation methodology for shared workspace groupware A1 - Baker,Kevin A1 - Greenberg,Saul A1 - Gutwin,Carl Y1 - 2002/// RP - NOT IN FILE SP - 96 EP - 105 T2 - Proceedings of the 2002 ACM conference on Computer supported cooperative work CY - New Orleans, Louisiana, USA PB - ACM U1 - 587093 N2 - Good real time groupware products are hard to develop, in part because evaluating their support for basic teamwork activities is difficult and costly. To address this problem, we are developing discount evaluation methods that look for groupware-specific usability problems. In a previous paper, we detailed a new set of usability heuristics that evaluators can use to inspect shared workspace groupware to see how they support teamwork. We wanted to determine whether the new heuristics could be integrated into a low-cost methodology that parallels Nielsen's traditional heuristic evaluation (HE). To this end, we examined 27 evaluations of two shared workspace groupware systems and analysed the inspectors' relative performance and variability. Similar to Nielsen's findings for traditional HE, individual inspectors discovered about a fifth of the total known teamwork problems, and that there was only modest overlap in the problems they found. Groups of three to five inspectors would report about 40-60% of the total known teamwork problems. These results suggest that heuristic evaluation using our groupware heuristics can be an effective and efficient method for identifying teamwork problems in shared workspace groupware systems SN - 1-58113-560-2 UR - http://doi.acm.org/10.1145/587078.587093 ER - TY - JOUR ID - 144 T1 - Sensemaking in Technology-Use Mediation: Adapting Groupware Technology in Organizations A1 - Bansler,Jorgen P.

In this paper, we argue that the appropriation and adaptation of groupware and other types of advanced CSCW technologies is basically a problem of sensemaking. We analyze how a group of "technology-use mediators" (Orlikowski etA al. Org. Sci. (1995) 6(4), 423) in a large, multinational company adapted a groupware technology (a "virtual workspace") to the local organizational context (and vice versa) by modifying features of the technology, providing ongoing support for users, and promoting appropriate conventions of use. Our findings corroborate earlier research on technology-use mediation, which suggests that such mediators can exert considerable influence on how a particular technology will be established and used in an organization. However, we also find that the process of technology-use mediation is much more complex and indeterminate than prior research suggests. The reason being, we argue, that new, advanced CSCW technologies, such as "virtual workspaces" and other groupware applications, challenge the mediators' and users' sensemaking, because the technologies are equivocal and, therefore, open to many possible and plausible interpretations SN - 0925-9724 UR - http://dx.doi.org/10.1007/s10606-005-9012-x ER - TY - CONF ID - 6 T1 - AwareMedia: a shared interactive display supporting social, temporal, and spatial awareness in surgery A1 - Bardram,Jakob E.

Despite these apparent challenges, very little work has been done to design technology which helps people coordinate highly cooperative work in such a critical setting. In this paper we propose a novel way of supporting coordination in this hectic and time-critical environment. AwareMedia is a system which promotes social, spatial, and temporal awareness in combination with a shared messaging system. AwareMedia runs on large interactive displays situated around the hospital, and it is designed especially to support coordination at an operation ward. We present the design, implementation, and deployment of AwareMedia and based on preliminary data from our on-going deployment, we discuss how AwareMedia is working in-situ SN - 1-59593-249-6 UR - http://doi.acm.org/10.1145/1180875.1180892 ER - TY - CONF ID - 2 T1 - Everyday encounters with context-aware computing in a campus environment A1 - Barkhuus,L A1 - Dourish,P Y1 - 2004/// RP - NOT IN FILE SP - 232 EP - 249 JF - Proceedings of Ubiquitous Computing T2 - Proceedings of Ubiquitous Computing N2 - As ubiquitous computing technologies mature, they must move out of laboratory settings and into the everyday world.

Our field work highlights the complex relationships between technology use and institutional arrangements - the roles, relationships, and responsibilities that characterize social settings. In heterogeneous groups, concerns such as location, infrastructure, access, and mobility can take on quite different forms, with very different implications for technology design and use.

This interaction can serve as an organizing structure for personally meaningful information geographies: map-like workspaces which accumulate 'trails' of our activity, which evolve over time but remain stable enough to provide the same fluency that we have with maps of physical places SN - 1-58113-454-1 UR - http://doi.acm.org/10.1145/506443.506470 ER - TY - CONF ID - 58 T1 - Analysis of gestures in face-to-face design teams provides guidance for how to use groupware in design A1 - Bekker,Mathilde M.

Most areas of computer science research, such as programming language implementation, distributed operating system design, or denotational semantics, are defined largely by technical problems, and driven by building upon and elaborating a body of past results. Ubiquitous computing, by contrast, encompasses a wide range of disparate technological areas brought together by a focus upon a common vision. It is driven, then, not so much by the problems of the past but by the possibilities of the future. Ubiquitous computing's vision, however, is over a decade old at this point, and we now inhabit the future imagined by its pioneers. The future, though, may not have worked out as the field collectively imagined. In this article, we explore the vision that has driven the ubiquitous computing research agenda and the contemporary practice that has emerged.

Maintenance of team cohesion is paramount to achieve such a surplus. Cohesion depends upon a variety of factors, such as effective allocation of tasks, effective communications, good knowledge sharing and accumulation of joint experience, and fair allocation of rewards so as to maintain a consistent perception of equity among team members. A technical system like groupware can never substitute for the social and organisational integration of team members, but it can fill many of the inevitable logistical, knowledge and communication gaps that always arise, especially in large and/or dispersed teams performing complex tasks. Such is the case considered below - a large workforce composed of more than 3,000 flight crew in a major European airline. Each pilot has a complex set of interactions with various departments of the company and his colleagues both when he is flying and when he is on the ground, at home or during training courses. The coordination problem is compounded by the fact that flight crew are a largely absent workforce and its management are flying as well. A whole industrial culture has evolved around the logistics of the pilot's job , i.e. pilots are considered, and regard themselves, as the other side of the airline, an odd breed, lonely strangers etc. In essence, as highly competent but isolated chaps who work almost as self-employed individuals. Changes in the airline industry are putting this culture under pressure: more integration is required at a time when the scale of operations is increasing in size and new pilots are hired. Working with pilots as users and designers of a groupware application, a requirements analysis has beeen carried out of team relationships in the flight crew department using the transaction costs approach. Prototypes have been developed for asynchronous and synchronous groupware systems that may find an application for the entire crew community and in particular for crew management. We believe that the work carried out so far not only offers interesting material for the design and development of groupware applications, but also sheds some light on alternative ways of building large scale computer-based information systems SN - 0-89791-402-3 UR - http://doi.acm.org/10.1145/99332.99348 ER - TY - CONF ID - 145 T1 - Technology choice as a first step in design: the interplay of procedural and sensemaking processes A1 - Bergman,Mark A1 - Mark,Gloria Y1 - 2002/// KW - design KW - methods KW - WORK RP - NOT IN FILE SP - 224 EP - 234 T2 - Proceedings of the 4th conference on Designing interactive systems: processes, practices, methods, and techniques CY - London, England PB - ACM U1 - 778744 N2 - Project design involves an initial selection of technologies, which has strong consequences for later stages of design.

Formal procedures were designed for the organization to perform repeatable, definable, and measurable actions. Yet, formal procedures obscured much about the processes actually being applied in selecting technologies and projects. In actuality, the formal procedures were interwoven with sensemaking activities so that technologies could be understood, compared, and a decision consensus could be reached.

A common situation is a single active presenter sharing a live view of her workstation screen with a passive audience, using simple hardware-based video signal projection onto a large screen or simple bitmap-based sharing protocols. This offers simplicity and some advantages over more sophisticated software-based replication solutions, but everyone has the exact same view of the application. This conflicts with the presenter's need to keep some information and interaction details private. It also fails to recognize the needs of the passive audience, who may struggle to follow the presentation because of verbosity, display clutter or insufficient familiarity with the application.Views that cater to the different roles of the presenter and the audience can be provided by custom solutions, but these tend to be bound to a particular application. In this paper we describe a general technique and implementation details of a prototype system that allows standardized role-specific views of existing single-user applications and permits additional customization that is application-specific with no change to the application source code. Role-based policies control manipulation and display of shared windows and image buffers produced by the application, providing semi-automated privacy protection and relaxed verbosity to meet both presenter and audience needs SN - 1-59593-271-2 UR - http://doi.acm.org/10.1145/1095034.1095039 ER - TY - CONF ID - 20 T1 - Mnemonic rendering: an image-based approach for exposing hidden changes in dynamic displays A1 - Bezerianos,A.

We ran a set of experiments to study how partially-distributed groups collaborate when skill sets are unequally distributed. Partially distributed groups are those where some collaborators work together in the same space (collocated) and some work remotely using computer-mediated communications. Previous experiments had shown that these groups tend to form semi-autonomous 'in-groups'. In this set of experiments the configuration was changed so that some player skills were located only in the collocated space, and some were located only remotely, creating local surplus of some skills and local scarcity of others in the collocated room. Players whose skills were locally in surplus performed significantly worse. They experienced 'collocation blindness' and failed to pay enough attention to collaborators outside of the room. In contrast, the remote players whose skills were scarce inside the collocated room did particularly well because they charged a high price for their skills SN - 1-59593-372-7 UR - http://doi.acm.org/10.1145/1124772.1124969 ER - TY - CHAP ID - 24 T1 - How conversation is shaped by visual and spoken evidence A1 - Brennan,S.E Y1 - 2004/// RP - NOT IN FILE T2 - World Situated Language Use: Psycholinguistic, Linguistic and Computational Perspectives on Bridging the Product and Action Traditions A2 - Trueswell,J.

The computer's power has been exploited to give quick visual form to abstract data, to interact, and to warp detail to follow the user's changing interest. Moreover, the design space of visualizations has been systematized with reference models, taxonomies, and monographs relating visualization to perceptual and graphical constraints. Looking ahead, however, I will argue that the era of pure information visualization is over. The path ahead depends on giving much more attention to the purposes of visualization and its use. Leaving aside communication, the purpose of information visualization is insight, or more particularly, a larger process that might be called sensemaking. I will sketch out the nature of sensemaking, exemplify it empirically in a practical, urgent setting, and suggest how theories of sensemaking could be developed. I will then describe systems that subsume information visualization as part of an emerging class of sensemaking systems combining visualization (the mind's eye) with semantic content analysis and sensemaking operations (the mind's muscle). Not surprisingly, a focus on sensemaking is a good generator of new visualizations.

These interfaces have a focus + context visualization on the front end and a semantic contextual computing engine on the back end. Ultimately they can be expected to have mixed initiatives.

Y1 - 1998/// N1 - The information presented in a document often consists of primary content as well as supporting material such as explanatory notes, detailed derivations, illustrations, and the like. We introduce a class of user interface techniques for fluid documents that supports the reader's shift to supporting material while maintaining the context of the primary material. Our approach initially minimizes the intrusion of supporting material by presenting it as a small visual cue near the annotated primary material. When the user expresses interest in the annotation, it expands smoothly to a readable size. At the same time, the primary material makes space for the expanded annotation. The expanded supporting material must be given space to occupy, and it must be made salient with respect to the surrounding primary material. These two aspects, space and salience, are subject to a negotiation between the primary and supporting material. This paper presents the components of our fluid document techniques and describes the negotiation architecture for ensuring that the presentations of both primary and supporting material are honored RP - NOT IN FILE SP - 123 EP - 132 CY - San Francisco, California, United States PB - ACM Press U1 - 288585 T3 - Proceedings of the 11th annual ACM symposium on User interface software and technology SN - 1-58113-034-1 ER - TY - CONF ID - 159 T1 - Sensemaking of Evolving Web Sites Using Visualization Spreadsheets A1 - Chi,Ed H.

This activity is characterized byemergence, where the participants' shared understanding develops gradually as they interact with each other and the source material. Our goal is to support collaborative interpretation by small, distributed groups. To achieve this, we first observed how face-to-face groups perform collaborative interpretation in a particular work context. We then synthesized design principles from two relevant areas: the key behaviors of people engaged in activities where emergence occurs, and how distributed groups work together over visual surfaces. We built and evaluated a system that supports a specific collaborative interpretation task. This system provides a large workspace and several objects that encourages emergence in interpretation.

Such communication usually benefits the initiator more than the target of the disruption. Previous research has indicated that awareness displays showing the workload of a target can reduce the harm interruptions inflict, but can increase the cognitive load on interrupters. This paper describes an experiment testing whether team membership influences interrupters' motivation to use awareness displays and whether the informational-intensity of a display influences its utility and cost. Results indicate interrupters use awareness displays to time communication only when they and their partners are rewarded as a team and that this timing improves the target's performance on a continuous attention task. Eye-tracking data shows that monitoring an information-rich display imposes a substantial attentional cost on the interrupters, and that an abstract display provides similar benefit with less distraction SN - 1-58113-810-5 UR - http://doi.acm.org/10.1145/1031607.1031638 ER - TY - CONF ID - 86 T1 - NotePals: lightweight note sharing by the group, for the group A1 - Davis,Richard C.

The system allows notes taken by group members in any context to be uploaded to a shared repository. Group members view these notes with browsers that allow them to retrieve all notes taken in a given context or to access notes from other related notes or documents. This is possible because NotePals records the context in which each note is created (e.g., its author, subject, and creation time). The system is lightweight because it fits easily into group members regular note- taking practices, and uses informal, ink-based user interfaces that run on portable, inexpensive hardware.

When there was a distinct majority/minority, groups exchanged more information, made better decisions, and took no more time when they used a GSS than when they did not use a GSS. In this case, the GSS enabled the minority to overcome the group's inertia toward the majority preference. In the uniform treatment where there was no majority preference, groups exchanged more information but made worse decisions and took more time when they used a GSS than when they did not.

This approach to building user model has an advantage that it is relatively easy to construct such models.

The bulk of this literature focuses on the individual with the goal of understanding the human perceptual system. In life, visual search is performed not only by individuals, but also by groups -- a team of doctors may study an x-ray and a team of analysts may study a satellite photograph. In this paper, we examine the issues one should consider when searching as a group. We present the details of an experiment designed to investigate the impact of group size on visual search performance, and how different display configurations affected that performance. We asked individuals, pairs, and groups of four people to participate in a baggage screening task in which these teams searched simulated x-rays for prohibited items. Teams conducted these searches on single monitors, a row of four monitors, and on a single horizontal display. Our findings suggest that groups commit far fewer errors in visual search tasks, although they may perform slower than individuals under certain conditions.

It happens whenever you confront a new, complex problem. At work, your boss says, Can you give a presentation next week on how wireless will affect our business? Or perhaps, you join a new committee, and wonder Who are these people? Who is in charge? What is our mission? What are we really going to do? Maybe you move to a new neighborhood, and you try to make sense of the streets, schools, parks, shopping, and neighbors. Or you say to yourself, I really need to get an updated cellphone--what has been happening with the current set of features, costs, plans and new gadgets? These kinds tasks begin a process of collecting and organizing data. Often the information can be organized into a fairly simple structure, one that helps to solve the problem. But as we well know, the process is sometimes ill-defined, iterative and complex: information retrieval, organization and task re-definition all interact in sometimes subtle ways. All of these behaviors lead to the creation of sense; that is, the process of sensemaking. Sensemaking can be a core professional task in itself, as it is for researchers, designers, or intelligence analysts. It arises when we change our place in the world or when the world changes around us. It arises when new problems, opportunities, or tasks present themselves, or when old ones resurface. It involves finding the important structure in a seemingly unstructured situation.

Previous results have demonstrated that visual information helps collaborative pairs to understand the current state of their task, ground their conversations, and communicate efficiently. However, collaborative technologies often impinge on the visual information needed to support successful collaboration. One example of this is the introduction of delayed visual feedback in a collaborative environment. We present results from two studies that detail the form of the function that describes the relationship between visual delay and collaborative task performance. The first study precisely demonstrates how a range of visual delays differentially impact performance and the collaborative strategies employed.

Structuration and sensemaking are two competing ways to view the social world within hospitals. To examine the impact of information technology in health care organizations, it is important to explore the dynamic interplay between clinical decisionmaking, outcomes of HIT implementation, and individual characteristics of the organizational setting. The adaptation of information technology within health care organizations is by its very nature quite complex. The recursive pattern of social interactions that shape the implementation of technologies within that setting is key. Structuration theory provides an understanding of human work as social interaction within that organizational culture, mediated by artifacts such as tools, language, rules and procedures, and open to change. The ICU provides multiple opportunities for sensemaking. It involves caring for multiple patients simultaneously; is subject to high levels of uncertainty and is provided under significant time constraints. It is highly interdependent work, necessitating shared sensemaking as well as individual sensemaking. Sensemaking is made partially visible in this context as clinicians communicate to each other what they think is the cause of the patient's symptoms and how to treat them in the form of discussions about patient care, consultation requests, ancillary testing, and the electronic medical record. The collaborative nature of work in the ICU lends itself to the application of sensemaking and structuration theories AD - University of Nevada-Las Vegas, Nevada, USA UR - PM:17917180 ER - TY - CONF ID - 94 T1 - NuggetMine: intelligent groupware for opportunistically sharing information nuggets A1 - Goecks,Jeremy A1 - Cosley,Dan Y1 - 2002/// RP - NOT IN FILE SP - 87 EP - 94 T2 - Proceedings of the 7th international conference on Intelligent user interfaces CY - San Francisco, California, USA PB - ACM U1 - 502732 N2 - NuggetMine is an intelligent groupware application that collaborates with a workgroup to increase information nugget sharing among the group.

However, the requirements of individuals and groups often coflict forcing designers to support one at the expense of the other. me tradeoff is particularly evident in the design of interaction techniques for shared workspaces. Individuds demand poweti and flexible means for interacting with the workspace and its artifacts, workgroups require information about each other to maintain awareness. Although these cotilcting requirements present real problems to designers, the tension can be reduced in some cases. We consider the tradeoff in three areas of groupware design workspace navigation, artifact manipulation, and view representation.

However, there is little principled information available about awareness that can be used by groupware designers. In this article, we develop a descriptive theory of awareness for the purpose of aiding groupware design, focusing on one kind of group awareness called i>workspace awareness. We focus on how small groups perform generation and execution tasks in medium-sized shared workspaces - tasks where group members frequently shift between individual and shared activities during the work session. We have built a three-part framework that examines the concept of workspace awareness and that helps designers understand the concept for purposes of designing awareness support in groupware. The framework sets out elements of knowledge that make up workspace awareness, perceptual mechanisms used to maintain awareness, and the ways that people use workspace awareness in collaboration. The framework also organizes previous research on awareness and extends it to provide designers with a vocabulary and a set of ground rules for analysing work situations, for comparing awareness devices, and for explaining evaluation results. The basic structure of the theory can be used to describe other kinds of awareness that are important to the usability of groupware SN - 0925-9724 UR - http://dx.doi.org/10.1023/A:1021271517844 ER - TY - CONF ID - 98 T1 - Improving interpretation of remote gestures with telepointer traces A1 - Gutwin,Carl A1 - Penner,Reagan Y1 - 2002/// RP - NOT IN FILE SP - 49 EP - 57 T2 - Proceedings of the 2002 ACM conference on Computer supported cooperative work CY - New Orleans, Louisiana, USA PB - ACM U1 - 587086 N2 - Gestural communication is an important part of shared work, both in face-to-face settings and distributed environments. However, gestures in groupware are often difficult to see and interpret because of disruptions to their motion caused by network jitter. One way to improve the visibility of remote gestures is by using traces-visualizations of the last few moments' of a remote pointer's motion. We carried out an experiment to test the effectiveness of traces in helping people interpret gestures. We found that telepointer traces dramatically improved people's accuracy and confidence in their decisions as jitter delays grew larger. Our results suggest that telepointer traces and other visualizations of interaction history can be used to enrich communication among remote collaborators SN - 1-58113-560-2 UR - http://doi.acm.org/10.1145/587078.587086 ER - TY - INPR ID - 165 T1 - Supporting Informal Collaboration in Shared-Workspace Groupware A1 - Gutwin,Carl A1 - Greenberg,S.

Y1 - 2007/// KW - WORK RP - NOT IN FILE JF - Journal of Universal Computing N2 - Shared-workspace groupware has not become common in the workplace, despite many positive results from research labs. One reason for this lack of success is that most shared workspace systems are designed around the idea of planned, formal collaboration sessions - yet much of the collaboration that occurs in a co-located work group is informal and opportunistic. To support informal collaboration, groupware must be designed and built differently. We introduce the idea of community-based groupware (CBG), in which groupware is organized around groups of people working independently, rather than shared applications, documents, or virtual places. Community-based groupware provides support for three things that are fundamental to informal collaboration: awareness of others and their individual work, lightweight means for initiating interactions, and the ability to move into closely-coupled collaboration when necessary. We demonstrate three prototypes that illustrate the ideas behind CBG, and argue that this way of organizing groupware supports informal collaboration better than other existing approaches.

VL - 16 IS - 5 N2 - OBJECTIVE: Oral presentation skills are central to physician-physician communication; however, little is known about how these skills are learned. Rhetoric is a social science which studies communication in terms of context and explores the action of language on knowledge, attitudes, and values. It has not previously been applied to medical discourse. We used rhetorical principles to qualitatively study how students learn oral presentation skills and what professional values are communicated in this process. DESIGN: Descriptive study. SETTING: Inpatient general medicine service in a university-affiliated public hospital. PARTICIPANTS: Twelve third-year medical students during their internal medicine clerkship and 14 teachers. MEASUREMENTS: One-hundred sixty hours of ethnographic observation. including 73 oral presentations on rounds. Discoursed-based interviews of 8 students and 10 teachers. Data were qualitatively analyzed to uncover recurrent patterns of communication. MAIN RESULTS: Students and teachers had different perceptions of the purpose of oral presentation, and this was reflected in performance. Students described and conducted the presentation as a rule-based, data-storage activity governed by "order" and "structure." Teachers approached the presentation as a flexible means of "communication" and a method for "constructing" the details of a case into a diagnostic or therapeutic plan. Although most teachers viewed oral presentations rhetorically (sensitive to context), most feedback that students received was implicit and acontextual, with little guidance provided for determining relevant content. This led to dysfunctional generalizations by students, sometimes resulting in worse communication skills (e.g., comment "be brief" resulted in reading faster rather than editing) and unintended value acquisition (e.g., request for less social history interpreted as social history never relevant). CONCLUSIONS: Students learn oral presentation by trial and error rather than through teaching of an explicit rhetorical model. This may delay development of effective communication skills and result in acquisition of unintended professional values. Teaching and learning of oral presentation skills may be improved by emphasizing that context determines content and by making explicit the tacit rules of presentation AD - Medical Service, San Francisco General Hospital, Department of Medicine, University of California, San Francisco, Calif 94143-0862, USA. rhaber@itsa.ucsf.edu UR - PM:11359549 ER - TY - CONF ID - 67 T1 - Coeno: enhancing face-to-face collaboration A1 - Haller,M.

For example, sustained operations require shift work, which results in hand-offs of responsibilities and need of information transfers. There is a growing interest to support their communications through advanced information technology. We observed usage of information artifacts in a pediatric intensive care unit to study information transfers to guide the design of support technology. In contrast to published studies, we examined the context of supporting environment that contains rich information sources gathered or tailored for verbal discourses. We called the supporting environment "information arena." Clinicians prepare for their personal information arena as well as the shared information arena (e.g., paper notes, charts, mobile computers).

VL - 40 IS - 5 N2 - OBJECTIVES: The time-oriented analysis of electronic patient records on (neonatal) intensive care units is a tedious and time-consuming task. Graphic data visualization should make it easier for physicians to assess the overall situation of a patient and to recognize essential changes over time. METHODS: Metaphor graphics are used to sketch the most relevant parameters for characterizing a patient's situation. By repetition of the graphic object in 24 frames the situation of the ICU patient is presented in one display, usually summarizing the last 24 h. RESULTS: VIE-VISU is a data visualization system which uses multiples to present the change in the patient's status over time in graphic form. Each multiple is a highly structured metaphor graphic object. Each object visualizes important ICU parameters from circulation, ventilation, and fluid balance. CONCLUSION: The design using multiples promotes a focus on stability and change. A stable patient is recognizable at first sight, continuous improvement or worsening condition are easy to analyze, drastic changes in the patient's situation get the viewers attention immediately AD - Department of Medical Cybernetics and Artificial Intelligence, University of Vienna, Austria. werner@ai.univie.ac.at UR - PM:11776741 ER - TY - JOUR ID - 126 T1 - Advanced visualization platform for surgical operating room coordination: distributed video board system A1 - Hu,P.F.

This article reports on the design and implementation of a passive status monitoring system in a 19-room surgical suite of a major academic medical center. Key design requirements considered included integrated real-time operating room status display, access control, security, and network impact. The system used live operating room video images and patient vital signs obtained through monitors to automatically update events and operating room status. Images were presented on a "need-to-know" basis, and access was controlled by identification badge authorization. The system delivered reliable real-time operating room images and status with acceptable network impact. Operating room status was visualized at 4 separate locations and was used continuously by clinicians and operating room service providers to coordinate operating room activities AD - Program in Trauma, Department of Anesthesiology, University of Maryland School of Medicine, Baltimore, Maryland, USA. phu@umm.edu UR - PM:17012154 ER - TY - CONF ID - 10 T1 - Techniques for addressing fundamental privacy and disruption tradeoffs in awareness support systems A1 - Hudson,Scott E.

Our goal is to identify the elements and mechanics of operation that enhance or threaten the dependability of the MDTM as a "system" and propose technologies and measures to make this system more reliable. In particular, we assess the effect of adding teleconferencing to the MDTM, and identify strengths and vulnerabilities introduced into the system by the addition of teleconferencing technology. We show that, with respect to the system's external task environment, rhythms of execution of pre-meeting and post-meeting activities are critical for MDTM success and that the extension of the MDTM to wider geographic locations with teleconferencing might disrupt such rhythms thereby posing potential threats to dependability. On the other hand, an analysis of vocalisation patterns demonstrates that despite difficulties related to coordination and awareness in video-mediated communication (evidenced by increased time spent in case discussion, longer turns, decreased turn frequency and near lack of informal exchanges) the overall case discussion structure is unaffected by the addition of teleconferencing technology into proceedings SN - 0925-9724 UR - http://dx.doi.org/10.1007/s10606-006-9035-y ER - TY - CONF ID - 104 T1 - Supporting collaborative process with conversation builder A1 - Kaplan,Simon M.

To address this issue, three help dialogue conditions distinguished by the range of shared visual information are compared. The analyses are focused on the comprehension problems raised by each condition. The results highlight that comprehension efficiency in help dialogues is not necessarily linked to the quantity of shared visual information. This study suggests two reasons for this observation: (a) Help requesters in remote help dialogues adapt the content of their requests to the effective amount of shared visual information, and (b) helpers adapt their interpretive strategies to the available shared resources. On the other hand, it is shown that the inability to visually share some specific task-related information strongly affects communication efficiency.

Patients' preference between bedside case presentation and conference-room case presentation is divergent in the literature. Residents seem to prefer the conference room. The objective of this study was to ascertain whether there was a difference of satisfaction and comfort between bedside case presentation and conference-room case presentation for the parents of patients hospitalized in the PICU and for the residents in training in the PICU. METHODS: Every child hospitalized in the PICU who had 2 consecutive morning rounds, performed in the presence of the same resident, attending pediatrician, and parent, was eligible for the study. The study began with the first patient's case presentation after admission in the PICU. Randomization was on the first case presentation: bedside or conference room. On the second day, the other type of case presentation was performed. After each round, the parents and the resident filled out a questionnaire. RESULTS: Twenty-seven parents of 22 patients answered both questionnaires, and 21 questionnaires were answered by residents. Parents' satisfaction was significantly higher during bedside case presentation (96 vs 92, answers reported on a 100-mm linear scale), they preferred bedside case presentation (95 vs 15), and they were more comfortable attending bedside teaching (89 vs 19). There was no difference in the residents' satisfaction nor in their comfort giving the actual case presentation. Residents, on the other hand, were significantly more comfortable asking questions (84 vs 69) and being asked questions (85 vs 67) during conference-room case presentation. A total of 81% of the parents wished that the next case presentation would take place at the bedside. CONCLUSIONS: This study demonstrates the feasibility of a clinical case presentation performed at the bedside in the PICU context that seems to satisfy parents without causing too much discomfort to residents. Thus, bedside case presentation could be a very good teaching strategy in university hospitals AD - Department of Pediatrics, Centre Hospitalier Universitaire de Sherbrooke, Sherbrooke, Quebec, Canada. marc-antoine.landry@usherbrooke.ca UR - PM:17671052 ER - TY - CONF ID - 105 T1 - Insight lab: an immersive team environment linking paper, displays, and data A1 - Lange,Beth M.

VL - 37 IS - 7 N2 - BACKGROUND: Socialisation into a community involves learning sanctioned ways of talking. This study investigates the case presentation genre as a site of socialisation into the clinical community of practice. METHODS: Sixteen oral case presentations and the teaching exchanges surrounding them (involving 11 students and 10 faculty members) were observed by paired researchers during inpatient paediatric medicine rounds. A total of 21 in-depth interviews were conducted with 11 students and 10 faculty. Both data sets were audio-recorded, transcribed and analysed for emergent themes and rhetorical strategies. RESULTS: Students emphasised case presentation as a school genre and described the ideal presentation as free of interruptions. As a consequence, students' presentation strategies were directed towards getting through the presentation without questions. In contrast, faculty responses suggested an understanding of the genre as a way of constructing shared professional knowledge. Faculty feedback was often explicit about critical issues in constructing shared knowledge, such as handling uncertainty. However, student presentations rarely reflected this feedback. CONCLUSIONS: The school genre described and enacted by students conflicts in key ways with the workplace genre evident in faculty feedback, suggesting that school and workplace iterations of case presentation may be at cross-purposes. Such cross-purposes have implications, because when students and teachers perceive a genre differently, a 'gap' is created in their interactions. Even rich and contextually situated feedback may get lost or distorted as it crosses this gap. Explicit acknowledgement of the multiple and flexible iterations of case presentation will improve the learning that novices experience through acquiring this central form of professional 'talk' AD - Centre for Research in Education, Faculty of Medicine, University of Toronto, Ontario, Canada. lorelei.lingard@utoronto.ca UR - PM:12834419 ER - TY - BOOK ID - 181 T1 - Synchronizing asynchronous collaborative learners A1 - Lundin,Johan Y1 - 2003/// N1 - This paper addresses the issue of different levels of progress in asynchronous collaborative learning activities. The context for this research is organizations of distributed and mobile practitioners. When introducing collaborative learning parallel to daily work tasks we cannot assume that all participants have the same possibility to actively engage. Therefore the learners can be at different levels of progress in the collaborative learning activity. To facilitate collaborative activity the progress of the participants has to be synchronized in some way. The main problem addressed in this paper is the difficulty for participants to keep a common progress, to enable discussions, in asynchronous collaborative learning. To address this problem three methods for synchronization (synchronization points) are suggested: locked scenes, written instruction and collaborative production. The three methods were implemented and evaluated in an organization using a Net-scenario, the Net-scenario as a system and a methodology based on role-playing to initiate collaborative learning. This system was suitable to use in the evaluation since it can be used asynchronously as well as synchronously, supports distributed participants and is dependent on collaborative discussion concerning the content presented KW - methods KW - WORK RP - NOT IN FILE SP - 427 EP - 443 PB - Kluwer, B.V.

A1 - Goose,S. A1 - Hedqvist,D. A1 - Beard,D.V. Y1 - 2004/// N1 - In a study of home-healthcare practitioners, we found that temporal trends contained in patients' clinical records form one of the most critical pieces of information when selecting and administering appropriate treatment. However, these records are comprised of quantitative and qualitative data, and recorded as a narrative. This format makes the extraction of historical trends difficult and time-consuming. To address this limitation, we introduce CareView, a system that utilizes a set of visualization techniques to increase the visibility of temporal trends in clinical narratives. Specifically, our system focuses on integrated temporal visualizations of numeric and qualitative records; a visualization to facilitate rapid comparison of a patient's condition against previously established care goals; and the ability to immediately visualize data as it is entered. Two experiments comparing the market-leading tabular interface with CareView revealed a significant reduction in the time required to identify trends in patients' conditions. However, interviews with nurses highlighted the importance of preserving the integrity of the holistic narrative and suggested extending the design space RP - NOT IN FILE SP - 1147 EP - 1150 CY - Vienna, Austria PB - ACM Press U1 - 986010 T3 - CHI '04 extended abstracts on Human factors in computing systems SN - 1-58113-703-6 ER - TY - JOUR ID - 106 T1 - What do groups need?

Cooperative gestures are interactions where the system interprets the gestures of more than one user as contributing to a single, combined command. Cooperative gestures can be used to enhance users' sense of teamwork, increase awareness of important system events, facilitate reachability and access control on large, shared displays, or add a unique touch to an entertainment-oriented activity.

Our research in designing office systems that better support this class of workers has included an in-depth study of traditional whiteboard use and the development of three large display systems, each addressing different aspects of and work practices involved in knowledge work. We have identified three cross-cutting themes in making these kinds of large display applications effective for supporting a variety of information management activities: context-awareness, privacy and content relevance, and informal and casual interaction techniques. In this chapter, we reflect on the ways in which each of these themes guided the design of our system prototypes and how they may inform future efforts in integrating large displays into the office environment.

While having multiple devices provides new opportunities to work in the face of changing resource deprivations, the management of devices is often problematic. The most salient problems are posed by 1) the physical effort demanded by various management tasks, 2) anticipating what data or functionality will be needed, and 3) aligning these efforts with work, mobility, and social situations. Workers' strategies of coping with these problems center on two interwoven activities: the physical handling of devices and cross-device synchronization. These aim at balancing risk and effort in immediate and subsequent use. Workers also exhibit subtle ways to handle devices in situ, appropriating their physical and operational properties.

However, one criticism of these techniques is that they do not make use of information about users and their work contexts. To address this problem, we developed groupware walkthrough, a new usability inspection technique for groupware. The technique is a substantive modification of cognitive walkthrough to include consideration for the complexities of teamwork. The two components of groupware walkthrough are a task model for identifying and analysing real-world collaborative tasks, and a walkthrough process for assessing a system's support for those tasks.

VL - 10 IS - 4 PB - ACM U1 - 966932 N2 - Researchers in Computer Supported Cooperative Work have recently developed discount evaluation methods for shared-workspace groupware. Most discount methods rely on some understanding of the context in which the groupware systems will be used, which means that evaluators need to model the tasks that groups will perform. However, existing task analysis schemes are not well suited to the needs of groupware evaluation: they either do not deal with collaboration issues, do not use an appropriate level of analysis for concrete assessment of usability in interfaces, or do not adequately represent the variability inherent in group work. To fill this gap, we have developed a new modeling technique called Collaboration Usability Analysis. CUA focuses on the teamwork that goes on in a group task rather than the taskwork. To enable closer links between the task representation and the groupware interface, CUA grounds each collaborative action in a set of group work primitives called the mechanics of collaboration. To represent the range of ways that a group task can be carried out, CUA allows variable paths through the execution of a task, and allows alternate paths and optional tasks to be modeled. CUA's main contribution is to provide evaluators with a framework in which they can simulate the realistic use of a groupware system and identify usability problems that are caused by the groupware interface SN - 1073-0516 UR - http://doi.acm.org/10.1145/966930.966932 ER - TY - CONF ID - 183 T1 - A groupware design framework for loosely coupled workgroups A1 - Pinelle,David A1 - Gutwin,Carl Y1 - 2005/// KW - design KW - WORK RP - NOT IN FILE SP - 65 EP - 82 T2 - Proceedings of the ninth conference on European Conference on Computer Supported Cooperative Work CY - Paris, France PB - Springer-Verlag New York, Inc. U1 - 1242033 N2 - Loosely coupled workgroups - where workers are autonomous and weakly interdependent - are common in the real world. They have patterns of work and collaboration that distinguish them from other types of groups, and groupware systems that are designed to support loose coupling must address these differences. However, loosely coupled groups have not been studied in detail in CSCW, and the design process for these groups is currently underspecified. This forces designers to start from scratch each time they develop a system for loosely coupled groups, and they must approach new work settings with little information about how work practices are organized. In this paper, we present a design framework to improve the groupware design process for loosely coupled workgroups. The framework was developed to provide designers with a better understanding of how groupware systems can be designed to support loosely coupled work practices. It is based on information from CSCW and organizational research, and on real-world design experiences with one type of loosely coupled group-- home care treatment teams.

It supports a lightweight form of exploratory data analysis (EDA) by integrating a familiar organization, the table, with graphical representations and a small set of direct manipulation operators. We examine the EDA process as a special case of a generic process, which we call sensemaking. Using a GOMS methodology, we characterize a few central EDA tasks and compare performance of the Table Lens and one of the best of the more traditional graphical tools for EDA i.e. Splus. This analysis reveals that Table Lens is more or less on par with the power of Splus, while requiring the use of fewer specialized graphical representations. It essentially combines the graphical power of Splus with the direct manipulation and generic properties of spreadsheets and relational database front ends.

Russell et al (1993) defined sensemaking as a process that searches for appropriate representation to answer task-specific questions. Their approach brought representation into the center of sensemaking research. My research follows this representational approach, narrowing it down to the construction of external and explicit representations in the sensemaking process because these representations provide a medium for people and computer systems to access and interact with the sensemaking process. The research approach is to interlace theoretical analyses and behavioral studies with system design and development in a spiraling process towards greater understanding of and effective support for sensemaking activities. The research starts with the examination of existing sensemaking theories, which lead to the development of a pilot sensemaking supporting system. Using this pilot system, a behavioral study was conducted to investigate representation construction in the early stage of sensemaking. Design implications were drawn from this experiment. Then a preliminary design space of systems supporting structure finding and exploration on the web was laid out. A system framework was proposed and a prototype was implemented. The system prototype provides a platform for further explorations in the design space and for further behavioral studies. This study finds that people not only get ideas for structuring representation from their existing knowledge, but also from the outside information world. Representation construction and information seeking are closely coupled in the process. The findings suggest important revisions of previous sensemaking theories and new opportunities for system design. A system framework is then proposed to help people locate and explore websites with high probabilities of containing useful structures.

We would like it to be a help rather than a hurdle in our work, particularly in collaborating with others. An emerging problem for both individuals and groups is information spread and neglect, where users have the same copy of the same work, stored on various conventional devices, but no way to keep track of where the most recent version resides. One type of computer support collaborative work application, groupware, tackles this problem, aiming to assist in joint authoring projects, where artifacts such as files, pictures, reports and sound are being gathered to form a whole. Such groupware systems - and we survey seven of them - vary in terms of their functional, architectural, focal, temporal, user involvement and platform dependencies. While we found a wide variety of options for each system, there were also strong commonalities. All of them work with closed communities or groups. There is no public file sharing. All users are aware of all other collaborators in the community and all systems focus on collaboration; not sharing. The comparison includes our own system Nomad, a framework for distributed resource management, with special emphasis placed on the accessibility of information stored on detached devices, such as personal computers, laptops, PDA's and flash-disks. In the comparison, Nomad has advantages of flexibility and temporal independence over the other systems, together with low requirements on the user, and a high level of mobility and platform independence. The contributions of this paper are twofold: we identify and define a specific type of CSCW, groupware, together with a set of criteria for evaluating such systems; and we survey and classify some of the main systems according to the criteria, as well as introducing a custom-designed system, Nomad. From these results, a collaborative group of workers can more easily select a specific groupware that suits its needs. Moreover, designers of new systems will find the commonality factors useful, so they can more easily position their own products SN - 1-59593-567-3 UR - http://doi.acm.org/10.1145/1216262.1216284 ER - TY - CONF ID - 29 T1 - An exploratory analysis of partner action and camera control in a video-mediated collaborative task A1 - Ranjan,Abhishek A1 - Birnholtz,Jeremy P.

Lessons include implications for more typical or "less than perfect" end users, especially around the adoption of collaboration technology. Also, there is a general, but subtle, lesson that studying successful users of technology (or "ideal end users" as we put it) can be as valuable as studying those who struggle with technology and highlight its shortcomings SN - 1-59593-223-2 UR - http://doi.acm.org/10.1145/1099203.1099248 ER - TY - CONF ID - 47 T1 - Designing the spectator experience A1 - Reeves,Stuart A1 - Benford,Steve A1 - O'Malley,Claire A1 - Fraser,Mike Y1 - 2005/// RP - NOT IN FILE SP - 741 EP - 750 T2 - Proceedings of the SIGCHI conference on Human factors in computing systems CY - Portland, Oregon, USA PB - ACM Press U1 - 1055074 N2 - Interaction is increasingly a public affair, taking place in our theatres, galleries, museums, exhibitions and on the city streets. This raises a new design challenge for HCI - how should spectators experience a performer's interaction with a computer? We classify public interfaces (including examples from art, performance and exhibition design) according to the extent to which a performer's manipulations of an interface and their resulting effects are hidden, partially revealed, fully revealed or even amplified for spectators. Our taxonomy uncovers four broad design strategies: 'secretive,' where manipulations and effects are largely hidden; 'expressive,' where they tend to be revealed enabling the spectator to fully appreciate the performer's interaction; 'magical,' where effects are revealed but the manipulations that caused them are hidden; and finally 'suspenseful,' where manipulations are apparent but effects are only revealed as the spectator takes their turn SN - 1-58113-998-5 UR - http://doi.acm.org/10.1145/1054972.1055074 ER - TY - CONF ID - 34 T1 - A multiple device approach for supporting whiteboard-based interactions A1 - Rekimoto,Jun Y1 - 1998/// RP - NOT IN FILE SP - 344 EP - 351 T2 - Proceedings of the SIGCHI conference on Human factors in computing systems CY - Los Angeles, California, United States PB - ACM Press/Addison-Wesley Publishing Co.

Traditional digital whiteboard systems often suffer from a limited capability to enter text and the handling of existing data. The large display surface of the whiteboard also makes traditional GUI design ineffective. Our proposed approach provides a hand-held computer for each participant which serves as a tool palette and data entry palette for the whiteboard. Just as an oil painter effectively uses a palette in his/her hand, this hand-held device offers an easy way to create a new text/stroke object, to select existing data from a network, to select pen attributes, and to control thewhiteboard application.

Sensemaking is the process of searching for a representation and encoding data in that representation to answer task-specific questions. Different operations during sensemaking require different cognitive and external resources. Representations are chosen and changed to reduce the cost of operations in an information processing task. The power of these representational shifts is generally under-appreciated as is the relation between sensemaking and information retrieval.

In this paper we identify a number of size considerations for tabletop design, and present an experiment to explore some of these issues, in particular the effects of group size and table size on the speed at which the task was performed, the distribution of work among group members, issues of shared resources, and user preference for table size. Our findings shed light on (1) how work strategies are affected by group size, (2) how social interaction varies with respect to table size, and (3) how the speed of task performance is influenced by group size but not by table size. In addition, our experiments revealed that for larger groups, designers might need to add additional vertical displays for shared information.

Y1 - 1992/// KW - WORK RP - NOT IN FILE SP - 7 EP - 40 JA - Computer Supported Cooperative Work (CSCW).An International Journal VL - 1 IS - 1 N2 - The topic of Computer Supported Cooperative Work (CSCW) has attracted much attention in the last few years. While the field is obviously still in the process of development, there is a marked ambiguity about the exact focus of the field. This lack of focus may hinder its further development and lead to its dissipation. In this paper we set out an approach to CSCW as a field of research which we believe provides a coherent conceptual framework for this area, suggesting that it should be concerned with the support requirements of cooperative work arrangements. This provides a more principled, comprehensive, and, in our opinion, more useful conception of the field than that provided by the conception of CSCW as being focused on computer support for groups. We then investigate the consequences of taking this alternative conception seriously, in terms of research directions for the field. As an indication of the fruits of this approach, we discuss the concept of 'articulation work' and its relevance to CSCW. This raises a host of interesting problems that are marginalized in the work on small group support but critical to the success of CSCW systems 'in the large', i. e., that are designed to meet current work requirements in the everyday world.

The quantitative and qualitative data collected suggest that chat does have advantages in some situations when used for informal communication along with video. The results provide evidence against the hypothesis that chat is a low bandwidth alternative only used when audio communication is unavailable.

Users will be moving frequently between their personal workspaces for personal and asynchronous work and shared workspaces for communication and synchronous cooperation. Also the system should supports users' everyday awareness of co-workers. For supporting such situation, this paper proposes a new technique to visualize workspaces as a set of layered virtual screens in three-dimensional space. In this way, groups' shared spaces are shown as background of users' personal spaces like as looking from a top personal layer down to a bottom public layer. In conventional groupware, user's workspace is divided into some shared spaces and a personal space to show all of them simultaneously, so the size of the personal space is very restricted. This layered perspective visualization alleviates this problem and also supports users' awareness by always showing shared spaces in background SN - 1-58113-065-1 UR - http://doi.acm.org/10.1145/320297.320305 ER - TY - CONF ID - 37 T1 - Single display privacyware: augmenting public displays with private information A1 - Shoemaker,Garth B.D.

Moreover, technical training and communication occur more and more between people who are located at a distance. We tested the hypothesis that seeing one person's visual focus of attention (represented as an eyegaze cursor) while debugging software (displayed as text on a screen) can be helpful to another person doing the same task. In an experiment, a group of professional programmers searched for bugs in small Java programs while wearing an unobtrusive head-mounted eye tracker. Later, a second set of programmers searched for bugs in the same programs. For half of the bugs, the second set of programmers first viewed a recording of an eyegaze cursor from one of the first programmers displayed over the (indistinct) screen of code, and for the other half they did not. The second set of programmers found the bugs more quickly after viewing the eye gaze of the first programmers, suggesting that another person's eye gaze, produced instrumentally (as opposed to intentionally, like pointing with a mouse), can be a useful cue in problem solving.

Others believe that it is more practical to evaluate groupware through usability inspection methods. Deciding between these two approaches is difficult, because it is unclear how they compare in a real evaluation situation. To address this problem, we carried out a dual evaluation of a groupware system, with one evaluation applying user-based techniques, and the other using inspection methods. We compared the results from the two evaluations and concluded that, while the two methods have their own strengths, weaknesses, and trade-offs, they are complementary. Because the two methods found overlapping problems, we expect that they can be used in tandem to good effect, e.g., applying the discount method prior to a field study, with the expectation that the system deployed in the more expensive field study has a better chance of doing well because some pertinent usability problems will have already been addressed SN - 1-58113-294-8 UR - http://doi.acm.org/10.1145/500286.500306 ER - TY - CONF ID - 35 T1 - When two hands are better than one: enhancing collaboration using single display groupware A1 - Stewart,Jason A1 - Raybourn,Elaine M.

VL - 13 IS - 6 N2 - Online pick'em games, such as the recent NCAA college basketball March Madness tournament, form a large and rapidly growing industry. In these games, players make predictions on a tournament bracket that defines which competitors play each other and how they proceed toward a single champion. Throughout the course of the tournament, players monitor the brackets to track progress and to compare predictions made by multiple players. This is often a complex sensemaking task. The classic bracket visualization was designed for use on paper and utilizes an incrementally additive system in which the winner of each match-up is rewritten in the next round as the tournament progresses. Unfortunately, this representation requires a significant amount of space and makes it relatively difficult to get a quick overview of the tournament state since competitors take arbitrary paths through the static bracket. In this paper, we present AdaptiviTree, a novel visualization that adaptively deforms the representation of the tree and uses its shape to convey outcome information. AdaptiviTree not only provides a more compact and understandable representation, but also allows overlays that display predictions as well as other statistics.

In order to dynamically enlarge an interaction area for the purpose of shared use, a flexible coupling of displays has been realized that overcomes the restrictions of display sizes and borders. Two ConnecTable displays dynamically form a homogeneous display area when moved close to each other. The appropriate triggering signal comes from built-in sensors allowing users to temporally combine their individual displays to a larger shared one by a simple physical movement in space. Connected ConnecTables allow their users to work in parallel on an ad-hoc created shared workspace as well as exchanging information by simply shuffling objects from one display to the other. We discuss the user interface and related issues as well as the software architecture. We also present the physical realization of the ConnecTables SN - 1-58113-438-X UR - http://doi.acm.org/10.1145/502348.502351 ER - TY - CONF ID - 44 T1 - Display and presence disparity in Mixed Presence Groupware A1 - Tang,Anthony A1 - Boyle,Michael A1 - Greenberg,Saul Y1 - 2004/// RP - NOT IN FILE SP - 73 EP - 82 T2 - Proceedings of the fifth conference on Australasian user interface - Volume 28 CY - Dunedin, New Zealand PB - Australian Computer Society, Inc. U1 - 976320 N2 - Mixed Presence Groupware (MPG) supports both co-located and distributed participants working over a shared visual workspace. It does this by connecting multiple single-display groupware workspaces together through a shared data structure. Our implementation and observations of MPG systems exposes two problems. The first is display disparity, where connecting heterogeneous tabletop and vertical displays introduces issues in how one seats people around the virtual table and how one orients work artifacts. The second is presence disparity, where a participant's perception of the presence of others is markedly different depending on whether a collaborator is co-located or remote. This is likely caused by inadequate consequential communication between remote participants, which in turn disrupts group collaborative and communication dynamics. To mitigate display and presence disparity problems, we determine virtual seating positions and replace conventional telepointers with digital arm shadows that extend from a person's side of the table to their pointer location ER - TY - CONF ID - 117 T1 - A framework for understanding the workspace activity of design teams A1 - Tang,John C.

A conventional view of workspace activity may be characterized as concerned only with storing information and conveying ideas through text and graphics. Empirical evidence shows that this view is deficient in not accounting for how the workspace is used: a) in a group setting, rather than by an individual, and b) as part of a process of constructing artifacts, rather than just a medium for the resulting artifacts themselves. An understanding of workspace activity needs to include the role of gestural activity, and the use of the workspace to develop ideas and mediate interaction.

The analysis focused on the group's shared drawing activity-their listing, drawing, gesturing and talking around a shared drawing surface. This analysis identified specific features of collaborative work activity that raise design implications for collaborative technology: (1) collaborators use hand gestures to uniquely communicate significant information; (2) the process of creating and using drawings conveys much information not contained in the resulting drawings; (3) the drawing space is an important resource for the group in mediating their collaboration; (4) there is a fluent mix of activity in the drawing space; and (5) the spatial orientation among the collaborators and the drawing space has a role in structuring their activity.

We studied a distributed group across three conditions: before installing Montage, with Montage, and after removing Montage.

We found that the group used Montage glances for short, lightweight interactions that were like face-to-face conversations in many respects. Yet like the phone, Montage offered convenient access to other people without leaving the office. Most glances revealed that the person was not available, so it was important to integrate other tools for coordinating future interaction.

U1 - 105997 N2 - When studying the use of Cognoter, a multi-user idea organizing tool, we noticed that users encountered unexpected communicative breakdowns. Many of these difficulties stemmed from an incorrect model of conversation implicit in the design of the software. Drawing on recent work in psychology and sociology, we were able to create a more realistic model of the situation our users faced and apply it to the system to understand the breakdowns. We discovered that users encountered difficulties coordinating their conversational actions. They also had difficulty determining that they were talking about the same objects and actions in the workspace. This work led to the redesign of the tool and to the identification of areas for further exploration.

To address this deficiency, we designed an awareness tool that uses screen sharing to provide information about other people's artifacts. People see others' screens in miniature at the edge of their display, can selectively raise a larger view of that screen to get more detail, and can engage in remote pointing if desired. Initial experiences show that people use our tool for several purposes: to maintain awareness of what others are doing, to project a certain image of themselves, to monitor progress and coordinate joint tasks, to help determine when another person can be interrupted, and to engage in serendipitous conversation and collaboration. People also balance awareness with privacy by using several privacy protection strategies built into our system SN - 1-59593-249-6 UR - http://doi.acm.org/10.1145/1180875.1180891 ER - TY - CONF ID - 77 T1 - Avoiding interference: how people use spatial separation and partitioning in SDG workspaces A1 - Tse,Edward A1 - Histon,Jonathan A1 - Scott,Stacey D.

While SDG is beneficial, there is risk of interference: when two people are interacting in close proximity, one person can raise an interface component (such as a menu, dialog box, or movable palette) over another person's working area, thus obscuring and hindering the other's actions. Consequently, researchers have developed special purpose interaction components to mitigate interference techniques. Yet is interference common in practice? If not, then SDG versions of conventional interface components could prove more suitable. We hypothesize that collaborators spatially separate their activities to the extent that they partition their workspace into distinct areas when working on particular tasks, thus reducing the potential for interference. We tested this hypothesis by observing co-located people performing a set of collaborative drawing exercises in an SDG workspace, where we paid particular attention to the locations of their simultaneous interactions. We saw that spatial separation and partitioning occurred consistently and naturally across all participants, rarely requiring any verbal negotiation. Particular divisions of the space varied, influenced by seating position and task semantics. These results suggest that people naturally avoid interfering with one another by spatially separating their actions. This has design implications for SDG interaction techniques, especially in how conventional widgets can be adapted to an SDG setting SN - 1-58113-810-5 UR - http://doi.acm.org/10.1145/1031607.1031647 ER - TY - CONF ID - 39 T1 - Rapidly prototyping Single Display Groupware through the SDGToolkit A1 - Tse,Edward A1 - Greenberg,Saul Y1 - 2004/// RP - NOT IN FILE SP - 101 EP - 110 T2 - Proceedings of the fifth conference on Australasian user interface - Volume 28 CY - Dunedin, New Zealand PB - Australian Computer Society, Inc. U1 - 976323 N2 - Researchers in Single Display Groupware (SDG) explore how multiple users share a single display such as a computer monitor, a large wall display, or an electronic tabletop display. Yet today's personal computers are designed with the assumption that one person interacts with the display at a time. Thus researchers and programmers face considerable hurdles if they wish to develop SDG. Our solution is the SDGToolkit, a toolkit for rapidly prototyping SDG. SDGToolkit automatically captures and manages multiple mice and keyboards, and presents them to the programmer as uniquely identified input events relative to either the whole screen or a particular window. It transparently provides multiple cursors, one for each mouse. To handle orientation issues for tabletop displays (i.e., people seated across from one another), programmers can specify a participant's seating angle, which automatically rotates the cursor and translates input coordinates so the mouse behaves correctly. Finally, SDGToolkit provides an SDG-aware widget class layer that significantly eases how programmers create novel graphical components that recognize and respond to multiple inputs ER - TY - JOUR ID - 171 T1 - Organizing the transfer of patient care information: the development of a computerized resident sign-out system A1 - Van Eaton,E.G.

Traditionally, residents ensured continuity of care by working long hours and minimizing the transfer of significant diagnostic or therapeutic responsibilities to other providers. The new 80-hour workweek has curtailed that practice and increased the pressure on trainees for workflow efficiency. We report on a study of information-handling routines among residents for the separate tasks of transfer of care ("sign-out") and daily patient care work (ward work). Using these results, an institution-wide computerized system was developed to centralize information-handling tasks and facilitate the management and transfer of patient care information. STUDY DESIGN: House staff from 31 resident-run inpatient and consult services at 2 teaching hospitals described current methods of maintaining patient information used during ward rounds and during sign-out. A subgroup of 28 residents then participated in the design of a computerized resident sign-out system to centralize patient information and produce lists for rounding and transferring care duties. Accuracy, flexibility, and portability were identified as key elements by the design team. RESULTS: Analysis of the type of information handled by residents caring for inpatients at our institution demonstrated common elements across many services. Most services used a paper patient list to manage both nightly sign-out and daily ward work, which required repeated recopying of patient data during the day. Utilizing medical information systems tools and rapid application development concepts, we constructed a computerized resident sign-out system ("UWCores"). This system combines the patient sign-out and daily ward work information in one central location. We believed this would improve the quality of information transferred during sign-out and enhance resident efficiency. During the design process, we identified rules that govern the type of clinical information that should be automatically versus manually updated. We observed an immediate acceptance by all residents and services that tried the system. CONCLUSIONS: This study shows that by combining downloaded patient data from hospital systems with resident-entered patient details, a computerized resident sign-out system can be a feasible, powerful, and popular tool. While its effect on patient safety and resident efficiency await the results of further studies, our study shows that this tool rapidly captured the attention of resident physicians and became widely used as a valuable means to centralize and organize sign-out and daily ward work information AD - Department of Surgery, University of Washington, Seattle, 98195, USA UR - PM:15232532 ER - TY - JOUR ID - 138 T1 - The effect of resource limits and task complexity on collaborative planning in dialogue A1 - Walker,Marilyn A.

Using the story of a firefighter who improvised a response to a fire by setting a back-fire while the rest of his crew panicked and ultimately perished, Weick examines the disintegration of role structure and sensemaking within an organization. He discusses sources of resilience that make groups less vulnerable, including improvisation, virtual role systems, the attitude of wisdom, and norms of respectful interaction. The purpose is to understand why organizations unravel and how they become more resilient.

In this paper we take the position that the concept of sensemaking fills important gaps in organizational theory. The seemingly transient nature of sensemaking belies its central role in the determination of human behavior, whether people are acting in formal organizations or elsewhere. Sensemaking is central because it is the primary site where meanings materialize that inform and constrain identity and action. The purpose of this paper is to take stock of the concept of sensemaking. We do so by pinpointing central features of sensemaking, some of which have been explicated but neglected, some of which have been assumed but not made explicit, some of which have changed in significance over time, and some of which have been missing all along or have gone awry. We sense joint enthusiasm to restate sensemaking in ways that make it more future oriented, more action oriented, more macro, more closely tied to organizing, meshed more boldly with identity, more visible, more behaviorally defined, less sedentary and backward looking, more infused with emotion and with issues of sensegiving and persuasion. These key enhancements provide a foundation upon which to build future studies that can strengthen the sensemaking perspective SN - 1526-5455 UR - http://dx.doi.org/10.1287/orsc.1050.0133 ER - TY - JOUR ID - 174 T1 - Evaluating self and others in electronic and face-to-face groups A1 - Weisband,S.

Results indicated that self-ratings of contribution were more inflated and less accurate in electronic communication than in face-to-face communication. Liking accounted for significant variance in ratings of others' contributions in face-to-face groups, whereas actual contribution accounted for significant variance in ratings of others in electronic groups.

We tested three specific hypotheses in the course of an office move. The greater availability of public digital data along with changes in people's jobs or interests should lead to wholescale discarding of paper data, while preparing for the move. Instead we found workers kept large, highly valued papar archives. We also expected that the major part of people's personal archives would be unique documents. However, only 49% of people's archives were unique documents, the remainder being copies of publicly available data and unread information, and we explore reasons for this. We examined the effects of paper-processing strategies on archive structure. We discovered different paper-processing strategies (filing and piling)that were relatively independent of job type. We predicated that filers' attempted to evaluate and catergorize incoming documents would produce smaller archives that were accessed frequently. Contrary to our predictions, filers amassed more information, and accessed it less frequently than pilers. We argue that filers may engage in premature filing: to clear their workspace, they archives information that later turns out to be of low value. Given the effort involved in organzing data, they are also loath to discard filed information, even when its value is uncertain.

To recommend strategies for minimizing or preventing these errors. SUMMARY BACKGROUND DATA: Surgical hospital practice is changing from a single provider to a team-based approach. This has put a premium on effective ITC. The Information Transfer and Communication Practices (ITCP) Project is a multi-institutional effort to: 1) better understand surgeon ITCP and their patient care consequences, 2) determine what has been done to improve ITCP in other professions, and 3) recommend ways to improve these practices among surgeons. METHODS: Separate, semi-structured focus group sessions were conducted with surgical residents (n = 59), general surgery attending physicians (n = 36), and surgical nurses (n = 42) at 5 medical centers. Case descriptions and general comments were classified by the nature of ITC lapses and their effects on patients and medical care. Information learned was combined with a review of ITC strategies in other professions to develop principles and guidelines for re-engineering surgeon ITCP. RESULTS:: A total of 328 case descriptions and general comments were obtained and classified. Incidents fell into 4 areas: blurred boundaries of responsibility (87 reports), decreased surgeon familiarity with patients (123 reports), diversion of surgeon attention (31 reports), and distorted or inhibited communication (67 reports). Results were subdivided into 30 contributing factors (eg, shift change, location change, number of providers). Consequences of ITC lapses included delays in patient care (77% of cases), wasted surgeon/staff time (48%), and serious adverse patient consequences (31%). Twelve principles and 5 institutional habit changes are recommended to guide ITCP re-engineering. CONCLUSIONS: Surgeon communication lapses are significant contributors to adverse patient consequences, and provider inefficiency.

This series aims to advance the practice of evidence-based medicine by helping in redesign of medical records, drawing on insights from psychology, information design, and medical informatics; and by promoting changes analogous to those occurring in the medical literature. The four papers look at: the uses of medical records and importance of organising them so doctors can use the data they contain; different methods doctors use to search for data and how design of records can help or hinder these approaches; how we interpret data once found, and how record formatting assists this process; and the issues raised by computerisation of records AD - School of Public Policy, University College London, UK. jeremy.wyatt@ucl.ac.uk UR - PM:9802289 ER - TY - JOUR ID - 122 T1 - A framework for epistemological analysis in empirical (laboratory and field) studies A1 - Xiao,Yan A1 - Vicente,Kim J Y1 - 2000/// RP - NOT IN FILE SP - 87 EP - 101 JF - Human Factors VL - 42 IS - 1 ER - TY - CONF ID - 118 T1 - Exploring collaborative navigation:: the effect of perspectives on group performance A1 - Yang,Huahai A1 - Olson,Gary M. Y1 - 2002/// RP - NOT IN FILE SP - 135 EP - 142 T2 - Proceedings of the 4th international conference on Collaborative virtual environments CY - Bonn, Germany PB - ACM U1 - 571899 N2 - In this paper, we describe a collaborative navigation task in CVE. As a work in process, we present a process model of the task and design an experiment to test hypotheses generated by this process model. Using this experimental approach, we investigated the effect of the dimension of egocentric-exocentric perspectives on collaborative navigation performance. Results favor an egocentric perspective display. We also discuss the implications of this work for the design of interaction techniques to support collaborative navigation and awareness in CVE SN - 1-58113-489-4 UR - http://doi.acm.org/10.1145/571878.571899 ER - TY - CONF ID - 36 T1 - Avoiding interference through translucent interface components in single display groupware A1 - Zanella,Ana A1 - Greenberg,Saul Y1 - 2001/// RP - NOT IN FILE SP - 375 EP - 376 T2 - CHI '01 extended abstracts on Human factors in computing systems CY - Seattle, Washington PB - ACM Press U1 - 634289 N2 - Our research concerns the design of interface components tailored for single display groupware (SDG) where multiple co-located people, each with their own input device, interact over a single shared display. In particular, we are concerned with 'interference' effects, where one person's raising of an interface component (e.g., a menu) can impede another's view and interaction on the shared screen. Our solution uses translucent interface components, where others can see through the obstructing component and continue their work underneath it. Our in-progress evaluation suggests this design lessens interference effects SN - 1-58113-340-5 UR - http://doi.acm.org/10.1145/634067.634289 ER -
