LifeMinder: an evidence-based wearable healthcare assistant

Recent needs for evidence-based healthcare systems are increasing. We have been developing a wearable healthcare assistant system LifeMinder that synchronously records physiological information and contextual information. LifeMinder is a long-term monitoring and easy retrieval system for an evidence-based healthcare. This paper discusses a prototype of LifeMinder. This prototype can sense pulse waves and user's actions / postures and capture contextual photos and continuous voices. These collected data are automatically synchronized, sent to a healthcare PC, stored in organized XML formats and can be easily retrieved on Web pages.
