We have developed an electronic safety support system to assist in the care of elderly people. The system uses a low power mobile phone (PHS) and a server computer. The PHS is carried by the subjects, and their location is identified within 100 m from the PHS antenna ID. The caregiver sets the patient's movement area with specialized computer software. When the patient leaves the area, the system automatically informs the caregiver via voice mode and sends the patient's location map by e-mail. The caregiver can monitor the current location and prior movement by the map displayed on server computer.
