LifeMinder: a wearable healthcare support system with timely instruction based on the user's context

摘要

Management of diet and exercise is especially significant in preventing "lifestyle-related diseases" for patients and subclinical cases. We developed a prototype of a wearable healthcare support system called "LifeMinder" that provides patients with timely instruction in accordance with their current context. "LifeMinder" is composed of a wristwatch-shaped wearable sensor module and a personal digital assistant (PDA). The sensor module measures 3-axis acceleration, pulse rate, galvanic skin reflex (GSR), and skin temperature. The PDA receives this data via Bluetooth/sup /spl trade// and recognizes the patient's general behavior such as "walking" or "eating". The recognition of these behaviors reduces the patient's mental and physical burden in daily healthcare and assists in support of medical treatment.
