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

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^™ 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.
