“Hospital work coordination and collaboration often requires mobility for acquiring proper information and resources. In turn, the spatial distribution and the mobility of clinicians can curtail the opportunities for effective communications making collaboration difficult. In this situation, a mobile hands-free voice communication system, Vocera, was introduced to enhance communication. It supports quick and impromptu conversations among coworkers for work coordination and collaboration anytime and anywhere. We study this deployment and present our findings concerning the impact of this communication system on the information flow. Our information flow framework's communication strategies help contrast the information processes before and after the deployment of Vocera.”

“To design information visualization tools for collaborative use, we need to understand how teams engage with visualizations during their information analysis process. We report on an exploratory study of individuals, pairs, and triples engaged in information analysis tasks using paper-based visualizations. From our study results, we derive a framework that captures the analysis activities of co-located teams and individuals. Comparing this framework with existing models of the information analysis process suggests that information visualization tools may benefit from providing a flexible temporal flow of analysis actions.”

“Since health care teams are often distributed across time and location, information sharing is crucial for effective patient care. Studying the use of a mobile information technology in a local hospital ward at two months and eleven months after its deployment identifies both short- and long-term phenomena and reveals a mismatch between the intentions behind the deployed mobile technology and the nurses' current work practices. We contrast the new mobile technology with the paper artifacts that were previously relied upon in nursing work. Finally, in light of these findings, we suggest design directions for future technology to support the nursing shift work.”

Tang, Charlotte and Carpendale, Sheelagh (2007): An observational study on information flow during nurses' shift change. In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 219-228. Available online
“We present an observational study that was conducted to guide the design and development of technologies to support information flow during nurses' shift change in a hospital ward. Our goal is to find out how the complex information sharing processes during nurses' brief shift change unfold in a hospital setting. Our study shows the multitude of information media that nurses access during the parallel processes of information assembly and disassembly: digital, paper-based, displayed and verbal media. An initial analysis reveals how the common information spaces, where information media are positioned and accessible by all participants, are actively used and how they interact with the personal information spaces ephemerally constructed by the participants. Several types of information are consistently transposed from the common information spaces to the personal information space including: demographics, historical data, reminders and to-dos, alerts, prompts, scheduling and reporting information. Information types are often enhanced with a variety of visual cues to help nurses carry out their tasks.”

“On traditional tables, people frequently use the third dimension to pile, sort and store objects. However, while effective and informative for organization, this use of the third dimension does not usually extend far above the table. To enrich interaction with digital tables, we present the concept of shallow-depth 3D -- 3D interaction with limited depth. Within this shallow-depth 3D environment several common interaction methods need to be reconsidered. Starting from any of one, two and three touch points, we present interaction techniques that provide control of all types of 3D rotation coupled with translation (6DOF) on a direct-touch tabletop display. The different techniques exemplify a wide range of interaction possibilities: from the one-touch technique, which is designed to be simple and natural, but inherits a degree of imprecision from its simplicity; through to three-touch interaction, which allows precise bimanual simultaneous control of multiple degrees of freedom, but at the cost of simplicity. To understand how these techniques support interaction in shallow-depth 3D, we present a user study that examines the efficiency of, and preferences for, the techniques developed. Results show that users are fastest and most accurate when using the three-touch technique and that their preferences were also strongly in favour of the expressive power available from three-touch.”

“Always-on media spaces broadcast video between collaborators to provide mutual awareness and to encourage casual interaction. This video can be easily recorded on the fly as a video trace. Ostensibly, people can review this video history to gain a better idea of the activities and availability of their collaborators. Such systems are obviously highly contentious, as they raise significant privacy concerns. However, the ease of capturing video means that video trace systems will appear in the near future. To push the boundaries and encourage debate about video trace technologies within the CSCW community, we created TIMELINE, a highly effective visualization system that combines ideas in slit scanning as used in interactive art to allow people to easily and rapidly explore a video history in detail. We describe its design and implementation, and begin the debate by offering preliminary reflections on how it can be used and misused. To encourage this debate, TIMELINE is freely available for others to try.”

“Designing collaborative interfaces for tabletops remains difficult because we do not fully understand how groups coordinate their actions when working collaboratively over tables. We present two observational studies of pairs completing independent and shared tasks that investigate collaborative coupling, or the manner in which collaborators are involved and occupied with each other's work. Our results indicate that individuals frequently and fluidly engage and disengage with group activity through several distinct, recognizable states with unique characteristics. We describe these states and explore the consequences of these states for tabletop interface design.”

“Previous research has shown that rotation and orientation of items plays three major roles during collaboration: comprehension, coordination and communication. Based on these roles of orientation and advice from kinesiology research, we have designed the Rotate'N Translate (RNT) interaction mechanism, which provides integrated control of rotation and translation using only a single touch-point for input. We present an empirical evaluation comparing RNT to a common rotation mechanism that separates control of rotation and translation. Results of this study indicate RNT is more efficient than the separate mechanism and better supports the comprehension, coordination and communication roles of orientation.”

“The difficulty of accessing information details while preserving context has generated many different focus-in-context techniques. A common limitation of focus-in-context techniques is their ability to work well at high magnification. We present a set of improvements that will make high magnification in context more feasible. We demonstrate new distortion functions that effectively integrate high magnification within its context. Finally, we show how lenses can be used on top of other lenses, effectively multiplying their magnification power in the same manner that a magnifying glass applied on top of another causes multiplicative magnification. The combined effect is to change feasible detail-in-context magnification factors from less than 8 to more than 40.”

Kruger, Russell, Carpendale, Sheelagh, Scott, Stacey D. and Greenberg, Saul (2004): Roles of Orientation in Tabletop Collaboration: Comprehension, Coordination and Communication. In Computer Supported Cooperative Work, 13 (5) pp. 501-537
“In order to support co-located collaboration, many researchers are now investigating how to effectively augment tabletops with electronic displays. As far back as 1988, orientation was recognized as a significant human factors issue that must be addressed by electronic tabletop designers. As with traditional tables, when people stand or sit at different positions around a horizontal display they will be viewing the contents from different angles. One common solution to this problem is to have the software reorient objects so that a given individual can view them right way up. Yet is this the best approach? If not, how do people actually use orientation on tables? To answer these questions, we conducted an observational study of collaborative activity on a traditional table. Our results show that the strategy of reorienting objects to a persons view is overly simplistic: while important, it is an incomplete view of how people exploit their ability to reorient objects. Orientation proves critical in how individuals comprehend information, how collaborators coordinate their actions, and how they mediate communication. The coordinating role of orientation is evident in how people establish personal and group spaces and how they signal ownership of objects. In terms of communication, orientation is useful in initiating communicative exchanges and in continuing to speak to individuals about particular objects and work patterns as collaboration progresses. The three roles of orientation have significant implications for the design of tabletop software and the assessment of existing tabletop systems.”
