In order to assist the people who have a tendency to wander away, a human tracking system using wireless multimedia technology was studied. This system consists of a compact mobile unit which can be carried in one's pocket and a base unit at home, both of which are connected through mobile public network. The positioning performance can be realized using GPS (Global Positioning System). In this paper first a tracking system structure and a performance principle are described. From the fundamental experiments, such as position measurement and position data transmission, the system can be modified to be used as human tracking system. Moreover, several subjects, such as compactness of the mobile unit, improvement of position precision, and high reliability of human tracking continue to be studied.
