PROBLEM TO BE SOLVED: To confirm the direction of a prescribed target point and a distance up to the point in real time. SOLUTION: When two mobile communication game machines 1A, 1B are installed, coordinate information (Xa, Xb) and coordinate information (Xb, Yb) are outputted from them at a prescribed timing. Then, a personal computer in a center 30 computes the distance between both and their direction on the basis of both pieces of coordinate information. Then, when a request comes from the mobile communication game machines 1A or 1B, data which indicates the computed distance and the computed direction is transmitted. The figure indicates a case in which data is transmitted to the mobile communication game machine 1A, the mobile communication game machine 1A which has received the data displays a distance up to the mobile communication game machine 1B, and it displays its direction by an arrow. |
