This paper describes the design of SIPGPS (Safe-in-Place GPS System) which is a GPS assistance environment helping track the elderly people outdoors. This environment is intended to facilitate the use of the GPS cell phones in assisting elderly people with walking safely in daily life. SIPGPS facilitates safe-in-place by assisting elderly people with emergency assistance via distance-based and duration-based notification control. The SIPGPS which provides the dedicated family easier way to locate their elderly family may expand the role of care in remote location.
