Stone-Type Physiological Sensing Device for Daily Monitoring in an Ambient Intelligence Environment

Recently there has been increasing research into mobile physiological sensing devices to explore the benefits in the areas of monitoring health and well-being. However, previous works have mainly focused on functionality, and less so on affective shape, comfort use, and stable sensing. In this work, we propose a stone-type physiological sensing device for general users, rather than professional experts. We found that our device was comfortable, stable and had aesthetic appeal for users during monitoring. To develop an affective shape, and to increase comfort, we applied a user-centered design process. We also used context-based physiological signal analysis to obtain stable analysis results according to individual users. As an application, we developed a rainbow ambient display to give visual feedback to users. We expect that this product can be applied in various healthcare applications.
