<p><P>PROBLEM TO BE SOLVED: To correctly determine whether or not an operator puts a part of his/her body to an operating part without providing a touch sensor. <P>SOLUTION: A command coordinates generation part 28 outputs command coordinates P1 corresponding to a trace of a prescribed variation pattern while a hand is not put on the operation part. A drive signal I/F unit 25 drives motors 17x, 17y so as to apply variation force to the operating part so that detected coordinates P2 coincide with the command coordinates P1. An operation state determining means 27 determines that a hand is put on the operating part when a difference between the command coordinates P1 and the detected coordinates P2 is larger than a difference thresholdδ. When a distribution of detected coordinates P2 for each distribution calculating time is smaller than a distribution thresholdε, the determining means 27 determines that the hand is off from the operating part. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
