Abstract

Aiming to reduce medical errors by 50% by 2010, the Institute of Medicine (IOM) has identified information technology (IT) as an important tool. One potential application of IT would be communicating with clinicians using affective multimodal interfaces. In this paper, we propose an Augmented Cognition (AugCog) related framework, Wearable Avatar Risk Display (WARD), for addressing medical errors. WARD is a dynamic, adaptive, and mobile display system that aims for delivering critical and contextual information meaningfully to clinicians based on their affective states. WARD is based on sociotechnical systems theory and serves two purposes: (1) To guide the development of a test bed for investigating effective and meaningful communication methods using avatars with lifelike behaviors (affective avatars) and (2) To investigate the interplay of affects, stress, and decision-making ability when interacting with affective avatars. Through a small exploratory study, we found that participants did not benefit from our avatars at this point. However, findings and suggestions from participants revealed that there is potential for affective avatars in critical or emergency situations.
