Abstract

In the present study we compare interaction techniques for using handheld devices together with stationary displays in a hospital setting. A set of prototype implementations were developed and tested for a pre-surgery scenario with pairs of physicians and patients. The participants were asked to rank the interaction techniques in order of preference. The results show highest ranking for a distributed user interface where the GUI elements reside on the handheld and where the stationary display is used for showing media content. An analysis of the factors affecting the usability shows that in addition to GUI usability, the interaction techniques were ranked based on ergonomic and social factors specific to the use situation. The latter include the physicality of the patient bed and how computing devices potentially interrupt the face-to-face communication between physician and patient. The study illustrates how the usability of interaction techniques for ubiquitous computing is affected by the ergonomic and social factors of each specific use context.
