<p><P>PROBLEM TO BE SOLVED: To solve the problem that in a frictional type operation feel feedback input device, a rotating operation part cannot be stopped at a reference position. <P>SOLUTION: A frictional type operation feel feedback input device is configured to calculate the magnitude of a frictional force based on a predetermined force curve from coordinates corresponding to the rotation angle of a rotating operation part. The force curve is turned into a valley at a reference position, and rises at both sides of the reference position. For example, when the coordinates of the rotation angle are located in an ascent section at the right side of the reference position (step S300: Yes), and the rotation angle decreases from the previous angle by a predetermined angle (θ<(θold-Δθ)) (step S302: Yes), the coordinates of the rotation angle are changed to the nearest reference positions at the left side (step S304). Thus, The magnitude of the frictional force can be changed to the value (minimum) of the valley bottom of the force curve to suppress wasteful power consumption. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
