Patent ID: 6906695

Claim:
A touch control apparatus comprising: a keyboard device which generates touch data indicative of strength of keying power; a touch curve memory which stores a touch curve indicative of a correspondence relation of velocity and touch, data; a corrector which corrects velocity values of said touch curve stored in said touch curve memory based on said touch data generated by said keyboard device to generate a new touch curve; and a mode switch which switches an operation mode of said touch control apparatus to a predetermined operation mode, wherein said corrector comprises: a correction coefficient generator which generates a correction coefficient composed of a ratio of one of said velocity values corresponding to one of said touch data generated by said keyboard device under said predetermined operation mode to a maximum value of said velocity values, wherein the correction coefficient is variable in accordance with the strength of the keying power; and a touch curve generator which multiplies a plurality of said velocity values by said correction coefficient to shift the touch curve, thereby generating the new touch curve.
