Title:
TACTILE SENSATION PRESENTATION DEVICE AND TACTILE SENSATION PRESENTATION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/080007
Kind Code:
A1
Abstract:
The present invention provides a tactile sensation presentation device which, with a simple configuration, is capable of presenting a good clicking sensation while reducing vibration at a stability point. The tactile sensation presentation device comprises: a detection unit that detects the rotation position of an operation part; a biasing part that biases, on the basis of a drive signal, the operation part along the rotation direction of the operation part; a signal generation unit that generates the drive signal which drives the biasing part on the basis of the rotation position; and a low pass filter unit that attenuates a high-frequency component of the drive signal and outputs the attenuated high-frequency component to the biasing part, wherein the signal generation unit generates a drive signal that biases the operation part to another side in the rotation direction when the rotation position is located between the first and second positions or a drive signal that biases the operation part to one side in the rotation direction when the rotation position is located between the first and third positions, and the low pass filter unit attenuates the high-frequency component of the drive signal more when the rotation position is in a first range that includes a first position but does not include second and third positions than when the rotation position is in a second range that includes the second position and that is outside the first range or in a third range that includes the third position and that is outside the first and second ranges.
