PROBLEM TO BE SOLVED: To solve a problem that it is difficult to recognize the relative positional relationship of plural portable terminals through only radio communication on a real-time basis when contents using the plural portable terminals at the same time are created.SOLUTION: Electrical conduction projections 3 are secured at three places at different intervals on side surfaces at four places of a portable terminal, and electrical conduction cases secured at three or more places are mounted on the front and back surfaces of the portable terminal 1. A portable terminal 1 is made to touch a side or surface thereof to an electrostatic capacitance type multi-touch recognizable display panel 4 of a portable terminal 2 in place of a human's finger to recognize the position of the display panel. Since the number and interval of the projections are fixed and known, which side or surface of the touched portable terminal 1 touches can be specified from the coordinates of three or more touching points. The information and the difference in absolute angle information obtained by acceleration sensors of these portable terminals are wirelessly communicated between the portable terminals, thereby dynamically achieving relative position information and angle information between the portable terminals.SELECTED DRAWING: Figure 1 |
