POSITION DETECTING SYSTEM AND POSITION DETECTING PROGRAM
A plurality of positional information transmitters 100, each of which transmits positional information to which a plurality of unit spaces are each uniquely assigned, are disposed on a ceiling. A mobile terminal 10 receives the positional information transmitted from each of the positional information transmitters 100 and changes a terminal-side image in accordance with the received positional information. Furthermore, the mobile terminal 10 transmits to a server 300 current positional information and operation information indicating an instruction inputted by a user. The server 300 changes, in accordance with the current positional information and the operation information received by the mobile terminal 10, a floor image displayed on a plurality of floor displays 200 disposed on a floor. Thus, it becomes possible to provide a highly interesting and novel position detecting system.
