Kusunoki, Diana S., Sarcevic, Aleksandra, Weibel, Nadir, Marsic, Ivan, Zhang, Zhan, Tuveson, Genevieve and Burd, Randall S. (2014): Balancing design tensions: Iterative display design to support ad hoc and interdisciplinary medical teamwork. In: Schmidt, Albrecht and Grossman, Tovi (eds.) SIGCHI Conference on Human Factors in Computing Systems CHI 14 April 26-May 1, 2014, Toronto, Canada. pp. 3777-3786.

In this paper, we describe how we developed an information display prototype for trauma resuscitation teams based on design ideas and feedback from clinicians. Our approach is grounded in participatory design, emphasizing the importance of gaining long-term commitment from clinicians in system development. Through a series of participatory design workshops, heuristic evaluation, and simulated resuscitation sessions, we identified the main information features to include on our display. Our results focus on how we balanced the design tensions that emerged when addressing the ad hoc, hierarchical, and multidisciplinary nature of trauma teamwork. We discuss the implications of balancing role-based differences for each information feature, as well as two major design tensions: process-based vs. state-based designs and role-based vs. team-based displays.

Boy, Guy A., Grossman, Tovi, Kusunoki, Diana S., Sarcevic, Aleksandra, Weibel, Nadir, Marsic, Ivan, Zhang, Zhan and Tuveson, Genevieve (2013): From STEM to STEAM: toward a human-centred education, creativity & learning thinking. In: Boy, Guy A., Pinet, Jean, Boy, Guy A. and Boy, Guy A. (eds.) 31st European Conference on Cognitive Ergonomics Sept., 2013, Toulouse, France. .

The 20th century was based on local linear engineering of complicated systems. We made cars, airplanes and chemical plants for example. The 21st century has opened a new basis for holistic non-linear design of complex systems, such as the Internet and air traffic management. Interconnectivity, communication and interaction are major attributes of our evolving society. But, more interestingly, we have started to understand that chaos theory may be more important than reductionism, to better understand and thrive on Earth. Systems need to be investigated and tested as wholes, which requires a cross-disciplinary approach and new conceptual principles and tools. Consequently, schools cannot continue to only teach isolated disciplines based on simple reductionism. Science, Technology, Engineering, and Mathematics (STEM) should also be integrated together with the Arts to promote creativity together with rationalization, and move (back) to STEAM (with an "A" for Arts). This concept shift emphasizes the possibility of longer-term socio-technical futures instead of short-term financial predictions that currently lead to uncontrolled economies. Human-centred design (HCD) can contribute to not only improving education technologies, systems and practices, but also as a discipline offering an integrated approach to learning by doing, expressing and critiquing, exploring possible futures, and understanding complex systems: HCD supports learning thinking.

Trauma centers are stressful, noisy and dynamic environments, with many people performing complex tasks, and with little in the way of information support. Information must be prioritized and filtered to avoid overload or loss. This work quantifies the information-selection parameters that will guide adaptive user interfaces for trauma teams.

Sarcevic, Aleksandra, Marsic, Ivan, Lesk, Michael E. and Burd, Randall S. (2008): Transactive memory in trauma resuscitation. In: Proceedings of ACM CSCW08 Conference on Computer-Supported Cooperative Work 2008. pp. 215-224.

This paper describes an ethnographic study conducted to explore the possibilities for future design and development of technological support for trauma teams. We videotaped 10 trauma resuscitations and transcribed each event. Using a framework that we developed, we coded each transcript to allow qualitative and quantitative analysis of the trauma teams' collaborative processes. We analyzed teams' tasks, interactions, and communication patterns that support information acquisition and sharing. Our results showed the importance of team transactive memory, but also pointed to inefficiencies in communication processes, which enable the functioning of this collective memory system. Based on quantitative and qualitative observations of trauma teamwork, we present opportunities for technological solutions that may reduce the cognitive effort needed for maintaining the working memory of trauma teams.

Correa, Carlos D. and Marsic, Ivan (2005): An optimization approach to group coupling in heterogeneous collaborative systems. In: GROUP05: International Conference on Supporting Group Work November 6-9, 2005, Sanibel Island, Florida, USA. pp. 274-283.

Recent proliferation of computing devices has brought attention to heterogeneous collaborative systems, where key challenges arise from the resource limitations and disparities. Sharing data across disparate devices makes it necessary to employ mechanisms for adapting the original data and presenting it to the user in the best possible way. However, this could represent a major problem for effective collaboration, since users may find it difficult to reach consensus with everyone working with individually tailored data. This paper presents a novel approach to controlling the coupling of heterogeneous collaborative systems by combining concepts from complex systems and data adaptation techniques. The key idea is that data must be adapted to each individual\'s preferences and resource capabilities. To support and promote collaboration this adaptation must be interdependent, and adaptation performed by one individual should influence the adaptation of the others. These influences are defined according to the user\'s roles and collaboration requirements. We model the problem as a distributed optimization problem, so that the most useful data--both for the individual and the group as a whole--is scheduled for each user, while satisfying their preferences, their resource limitations, and their mutual influences. We show how this approach can be applied in a collaborative 3D design application and how it can be extended to other applications.

Correa, Carlos D. and Marsic, Ivan (2004): Software Framework for Managing Heterogeneity in Mobile Collaborative Systems. In Computer Supported Cooperative Work, 13 (5) pp. 603-638.

Heterogeneity in mobile computing devices and application scenarios complicates the development of collaborative software systems. Heterogeneity includes disparate computing and communication capabilities, differences in users needs and interests, and semantic conflicts across different domains and representations. In this paper, we describe a software framework that supports mobile collaboration by managing several aspects of heterogeneity. Adopting graph as a common data structure for the application state representation enables us to develop a generic solution for handling the heterogeneities. The effect external forces, such as resource constraints and diverging user interests, can be quantified and controlled as relational and attribute heterogeneity of state graphs. When mapping the distributed replicas of the application state, the external forces inflict a loss of graph information, resulting in many-to-one correspondences of graph elements. A key requirement for meaningful collaboration is maintaining a consistent shared state across the collaborating sites. Our framework makes the best of maximizing the state consistency, while accommodating the external force constraints, primarily the efficient use of scarce system resources. Furthermore, we describe the mobility aspects of our framework, mainly its extension to peer-to-peer scenarios and situations of intermittent connectivity. We describe an implementation of our framework applied to the interoperation of shared graphics editors across multiple platforms, where users are able to share 2D and 3D virtual environments represented as XML documents. We also present performance results, namely resource efficiency and latency, which demonstrate its feasibility for mobile scenarios.

Velez, Maria, Tremaine, Marilyn M., Sarcevic, Aleksandra, Dorohonceanu, Bogdan, Krebs, Allan and Marsic, Ivan (2004): "Who's in charge here?" communicating across unequal computer platforms. In ACM Transactions on Computer-Human Interaction, 11 (4) pp. 407-444.

People use personal data assistants in the field to collect data and to communicate with others both in the field and office. The individual in the office invariably has a laptop or a high-end personal workstation and thus, significantly more computing power, more screen real estate, and higher volume input devices, such as a mouse and keyboard. These differences give the high-end user the ability to represent and manipulate collaborative tasks more effectively. It is therefore useful to know what impact these differences have on work performance and work communications. Four different platform combinations involving a PC and a PDA were used to examine the effect of communicating via heterogeneous computer platforms. The PC platform used a mouse, a keyboard, and a 3-dimensional screen display. The PDA platform used a stylus, soft buttons, and a 2-dimensional screen display. A variation of the Tetris wall-building game called Slow Tetris was used as the subjects' collaborative task. A second factor in the experiment was role asymmetry. One subject was arbitrarily put in charge of the task solution in all of the combinations. An analysis of the solution times found that subjects with mixed platforms worked slower than their homogeneous counterparts, that is, a person in charge with a PC worked faster if his partner had a PC. An in-depth analysis of the communication patterns found significant differences in the exchanges between heterogeneous and homogenous combinations. The PC-to-PDA combination (with the person on the PC in charge of the solution) took significantly more time than the PC-to-PC combination. This extra time appears to come from the disadvantage of having a partner on the PDA who is unable to help in solving the problems. The PDA-to-PC combination took approximately the same amount of time as the PDA-to-PDA combination despite having one team member with a better representation. This member was, unfortunately, not in charge of the solution. The PDA-to-PC heterogeneous combination exhibited more direction giving, less one-sided collaboration, and more takeover attempts than any of the other combinations. Overall, roles were maintained in the partnerships except for the person with the PDA directing the person with the PC.

Ionescu, Mihail and Marsic, Ivan (2003): Tree-Based Concurrency Control in Distributed Groupware. In Computer Supported Cooperative Work, 12 (3) pp. 329-350.

We present a novel algorithm, called dARB, for solving the concurrency control problem in distributed collaborative applications. The main issue of concurrency control is resolving the conflicts resulting from simultaneous actions of multiple users. The algorithm reduces the need for manual conflict resolution by using a distributed arbitration scheme. The main advantages of our approach are the simplicity of use and good responsiveness, as there are no lock mechanisms. Our algorithm requires the applications to use a tree as the internal data structure. This makes it application independent and suitable for general collaborative applications. The tree requirement is reasonable since many new applications use XML (extensible Markup Language) for data representation and exchange, and parsing XML documents results in tree structures. Example applications of the algorithm, a group text editor and a collaborative 3D virtual environment called cWorld, are implemented and evaluated in the DISCIPLE collaboration framework. We also introduce awareness widgets that users avoid generating the conflicting events and help in manual conflict resolution.

Marsic, Ivan and Dorohonceanu, Bogdan (2003): Flexible User Interfaces for Group Collaboration. In International Journal of Human-Computer Interaction, 15 (3) pp. 337-360.

Flexible user interfaces that can be customized to meet the needs of the task at hand are particularly important for telecollaboration. This article presents the design and implementation of a user interface for DISCIPLE, a platform-independent telecollaboration framework. DISCIPLE supports sharing of Java components that are imported into the shared workspace at run-time and can be interconnected into more complex components. As a result, run-time interconnection of various components allows user tailoring of the human-computer interface. Software architecture for customization of both a group-level and application-level interfaces is presented, with interface components that are loadable on demand. The architecture integrates the sensory modalities of speech, sight, and touch. Instead of imposing one "right" solution onto users, the framework lets users tailor the user interface that best suits their needs. Finally, laboratory experience with DISCIPLE tested on a variety of applications with the framework is discussed along with future research directions.

Correa, Carlos D. and Marsic, Ivan (2003): Software framework for managing heterogeneity in mobile collaborative systems. In: Tremaine, Marilyn M. and Simone, Carla (eds.) Proceedings of the International ACM SIGGROUP Conference on Supporting Group Work 2003 November 9-12, 2003, Sanibel Island, Florida, USA. pp. 125-134.

Heterogeneity aspects in mobile collaborative systems, such as differences in user's interest, semantic conflicts across different domains and representations, and disparate device capabilities, cause difficulties in developing software applications. One of the key problems for collaborative applications is maintaining a consistent shared state. In this paper, we describe a framework that manages several aspects of heterogeneity to maintain consistency across the collaborating sites. We assume graph data structure for application state representation. Our framework is based on structural and semantic mappings between graph structures. The mapping can be customized to meet different requirements through user-defined policies and rules. An important constraint is efficient use of scarce system resources. We describe several applications built using the framework to collaboratively share XML documents. The XML documents in our case are 2D/3D representations of virtual worlds. We also show the performance results of our framework which demonstrate its feasibility for mobile scenarios.

Flippo, Frans, Krebs, Allen and Marsic, Ivan (2003): A framework for rapid development of multimodal interfaces. In: Proceedings of the 2003 International Conference on Multimodal Interfaces 2003. pp. 109-116.

Despite the availability of multimodal devices, there are very few commercial multimodal applications available. One reason for this may be the lack of a framework to support development of multimodal applications in reasonable time and with limited resources. This paper describes a multimodal framework enabling rapid development of applications using a variety of modalities and methods for ambiguity resolution, featuring a novel approach to multimodal fusion. An example application is studied that was created using the framework.

Sharing single-user software applications is a major goal of synchronous groupware particularly because the majority of applications continues to be developed for single users. We present a mechanism for sharing collaboration-transparent single-user applications in our DISCIPLE collaboration framework. DISCIPLE is the equivalent of a Web browser that allows sharing applets (Java components, both transparent and aware of collaboration). It allows users with no programming background to quickly assemble arbitrary collaborative applications. Even though the presented solutions are specific to Java, many apply to other platforms as well. We introduce a novel concept of resource servers to solve the problem of resource access in collaboration-transparent applications. We also discuss the limitations of the framework in particular and of sharing collaboration-transparent applications in general. The framework has been implemented and tested on a variety of applications. Preliminary experimental results are reported.
