CONTACT POSITION DIRECTION DISTANCE CALCULATING METHOD AND TOUCH FEELING OPERATION PAD

摘要

PROBLEM TO BE SOLVED: To provide a touch feeling operation pad which can grasp moving quantity with touch feeling when the pad is continuously stroked with a finger tip and writing materials by providing matrix-like projecting and recessing parts on the surface of the pad. SOLUTION: The touch feeling pad 1 has a pad part 102 having plural dome- like key caps KC11-KC55 arranged in a matrix form on the upper part of the main body 101. A light emission diode 103 for remote control transmission is provided on the front part of the main body 101. A switch mechanism constituted of plural key switches SW11-SW55 is provided in the main body 101 so that they correspond to the array of the respective key caps KC11-KC55. When the surfaces of the key caps KC11-KC55 are stroked by the finger tip and the pen tip, continuous click feeling is transmitted to the finger tip or fingers holding the pen by moving the finger tip and the pen tip by straddling the surfaces of the plural dome-like key caps.
