Mediated and Mobile Communication for Experts
KTH, School of Computer Science and Communication (CSC), Media Technology and Interaction Design, MID.
2014 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

This thesis focuses on systems for mediated communication that run on mobile technology. The aim has been to give an answer to the question about what require- ments there are for situation awareness for domain experts when communication is secondary and supports the primary task.

This thesis originated in a critical approach to the common practice of design- ing mediated communication systems with the face-to-face meeting as a guiding scenario. Instead, this thesis explores a design process that is based on the task and the strength of the technology itself. Different tasks do, of course, make different de- mands on a system, and a task that is strongly connected to the face-to-face meeting will probably be best served by a system that is designed from that perspective.

Three cases that are presented in this thesis share three common themes that have characteristics that set them apart from the face-to-face meeting. The first theme is that the communication is a secondary task that is used to support a primary task. The second theme is that the cases involve domain experts active in the primary task. The use of experts implies that communication will be task- centered and also that the need for information to sustain a valuable situation awareness may be different from a person with less experience in the domain. The third theme is that all cases and the corresponding tasks benefit from some kind of situation awareness among the participants for optimal execution of the task. The three cases are based on:

Wearable computers using mediated communication with wearable computers and how to handle interruptions for users of such computers

Multidisciplinary team meetings improving access to patient information and enabling individual and group interaction with this information

Trauma resuscitation giving a remote trauma expert’s correct and valuable in- formation while minimizing disturbance when supporting a local trauma re- suscitation team

Prototypes are central in all three cases, and different prototypes have been designed and evaluated to validate the benefit of designing tools for communication that do not try to replicate the face-to-face meeting.

The main findings in this thesis show that the shift of focus to the primary task when designing mediated communication systems has been beneficial in all three cases. A conflict between the secondary communication that is used to support sit- uation awareness and the primary task has been identified. Full situation awareness should therefore not be a goal in these designs but communication should support enough situation awareness to benefit the primary task with minimal disturbance to it.

Abstract [en]

A wearable computer equipped with a head-mounted display allows its user to receive notifications and advice that is readily visible in her field of view. While needless interruption of the user should be avoided, there are times when the information is of such importance that it must demand the user's attention. As the user is mobile and likely interacts with the real world when these situations occur it is important to know in what way the user can be notified without increasing her cognitive workload more than necessary. To investigate ways of presenting information without increasing the cognitive workload of the recipient, an experiment was performed testing different approaches. The experiment described in this paper is based on an existing study of interruption of people in human-computer interaction, but our focus is instead on finding out how this applies to wearable computer users engaged in real world tasks.

Abstract [en]

An important part of making a wearable computer unobtrusive is the user interface and the way it interrupts the user The amount of interruption that have to be made on the users primary task should be minimized. Usage without interruption is of course best for the performance of the primary task but is often not possible as many tasks that the wearable computer is involved in do need interaction with the user It is therefore important to understand what type of interruption that will benefit the user most. The question about which interruption that causes the least amount Of stress for the user is as important as which interruption that gives the best performance. This paper continues on previous work where performance of the users was measured for different types of interruption. In this paper subjective data is analyzed to understand how to build user interfaces for wearable computers and head mounted displays that considers stress and other subjective variables.

Abstract [en]

In order to improve collaboration on, and visualisation of, patient information in medical multi-disciplinary team meetings, we have developed a system that presents information from different medical systems to be used as a support for the decision process. Based on field studies, we have implemented a high-fidelity prototype on tablet-sized displays, and tested it in a realistic setting. Our evaluation proved that more patient information can efficiently be displayed to all meeting participants, compared to the current situation. Interaction with the information, on the other hand, proved to be a complicated activity that needs careful design considerations; it should ultimately be based on what roles the meeting participants have, and what tasks they should complete. Medical decision-making is a complex area, and conducting interaction design in this area proved complex too. We foresee a great opportunity to improve medical work, by introducing collaborative tools and visualisation of medical data, but it requires that interaction design becomes a natural part of medical work.

Abstract [en]

We present results from a study of information needs when teleconsultation is used in trauma resuscitation. Three trauma team training sessions including 14 patient cases were observed together with field studies at emer- gency units. Technology probes like headcams and visu- alization of data usually available in the trauma room were used to better understand what information that is impor- tant or not for the remote expert to achieve a satisfactory Situation Awareness to support the trauma resuscitation. It was found that the two major information sources that the remote expert relies on are the vital signs and an overview, not necessarily with high video quality, of the team in the trauma room.

Abstract [en]

We have designed and developed a mobile prototype that sup- ports a remote trauma surgeon that has been given the task to guide a trauma resuscitation at a local hospital. The design is based on field studies of trauma resuscitations, and on using different probes during trauma training sessions. The proto- type was tested in a trauma training session and evaluated in contextual interviews. The design focuses on what informa- tion that the remote trauma surgeon needs in order to support the trauma team and how the information should be presented in order to enhance situation awareness. Our results show that a consideration of the elements in the environment that add to situation awareness can open up for easier inclusion of mo- bile technology. We show the importance to design for the whole flow of information to achieve acceptance of the de- sign among future users.
