Abstract
Haptic device includes: detection part for detecting operation part's rotation position; biasing part for biasing operation part along operation part's rotation direction based on drive signal; signal generation part for generating drive signal for driving biasing part based on rotation position; and low-pass filter part for outputting drive signal to biasing part by attenuating high-frequency component. Signal generation part generates drive signal for causing biasing to other side in rotation direction when rotation position is between first and second positions, and for causing biasing to one side when rotation position is between first and third positions. Low-pass filter part attenuates drive signal's high-frequency component more strongly when rotation position is in first range including first position and not including second and third positions than when in second range including second position and outside first range or third range including third position and outside first and second ranges.
