GAME SYSTEM AND POSITION AWARENESS METHOD USING POSITION AWARENESS AT UBIQUITOUS SENSOR NETWORK

摘要

It attends a banquet in the A platforms of a ubiquitous sensor network and its location recognition method and identifies that game system is definitely arranged to discover the position of a user or a game tool by using a ubiquitous sensor network environment, to provide game, the 3D environment of a reality is used. One meeting point (300) transmits an initializing signal. Multiple additional type nodes (200) receive initializing signal, transmit ultrasonic wave at certain time intervals. The arrival time for the ultrasonic wave that one location provider (100) is received by a driven timer measurement, transmission measurement time data to meeting point. A situation management server (400) input time in meeting point has received data, analyzes the time data of input, confirms a position of location provider.
