LifeMinder^TM:状況認識を用いたウェアラブル健康管理システム

抄録

We developed a prototype of wearable healthcare support system ‘LifeMinder^TM’. It is a handy system composed of a wristwatch-shaped wearable sensor module and a personal digital assistant (PDA). The wearable sensor module is equipped with sensors of accelerometer, pulse meter, thermometer, and galvanic skin reflex (GSR) electrodes. It communicates wih the PDA, which monitors the user’s context: health conditions, movements and behaviors, via a Bluetooth. We developed algorithms to recognize the user’s movement from wrist motion and to detect the beginning of a meal from pulse rates and GSR values. The accuracies of both algorithms are about 90%. The system uses this information to guide the user in daily healthcare in real time. It also works in cooperation with the other measuring instruments, such as a blood glucose sensor, via a Bluetooth.
