<p><P>PROBLEM TO BE SOLVED: To provide an operation contact detection device can detect the operation contact of an operation body part with an operation unit at high accuracy and also easily specify an operation direction. <P>SOLUTION: A heartbeat waveform of a sitting occupant is detected with a heartbeat detection part 41 provided on a seat, whereas, a pulse detection part 42 is provided to an input operation part side. A pulse waveform is detected with the pulse detection part 42 as the operation body such as the finger of the occupant contacts, and existence of operation contact to the input operation part is detected based on the comparison result of the detected heartbeat waveform and the pulse waveform. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
