Development of a context-aware and support system using wearable information devices with Bluetooth communication facility

Abstract

We implemented a wearable system which monitors user′s state real-timely and offers services for activity support and healthcare based on the user′s objective, preference, location, and state. User′s state is monitored by newly developed wristwatch-type motion sensor and foot pressure shoes which send data to a wearable PC via Bluetooth and the appropriate contents are given on a mobile eye glass display without hindering action and annoying to the user. The algorithm was verified for improving the accuracy of user′s state estimation.
