<p>PROBLEM TO BE SOLVED: To accurately recognize a position pointed by a user. SOLUTION: A coordinate indicating tool 2 is constituted of a pointer 5 provided at the top end and a grasping part 6. The pointer 5 is made transparent and flexible, and constituted of members for absorbing ultrasonic waves like a finger-point. When plotting by bringing the coordinate indicating tool 2 into contact with the touch panel 4, the plotting position can be transmitted and accurately recognized when the pointer 5 is formed of transparent materials. Also, the point position can be further clearly recognized by providing marking 9 at the center of gravity position of a contact face brought into the touch panel 4 at the top end of the pointer 5.</p> |
