Haptic device and haptic method

A haptic device, comprising:

• an operation part capable of being operated to travel along one direction;
• a detection part configured to detect a travel position of the operation part;
• a biasing part capable of biasing the operation part along the one direction;
• a signal generation part configured to generate a drive signal to the biasing part based on the travel position;
• and
• a low-pass filter part configured to output the drive signal to the biasing part by attenuating a high-frequency component of the drive signal,
• wherein when the travel position of the operation part is located between a first position and a second position that is on one side of the first position in the one direction, the signal generation part generates the drive signal for causing the biasing part to perform biasing to the other side in the one direction,
• wherein when the travel position is located between the first position and a third position that is on the other side of the first position, the signal generation part generates the drive signal for causing the biasing part to perform biasing to the one side in the one direction, and
• wherein the low-pass filter part attenuates the high-frequency component of the drive signal more strongly when the travel position is in a first range including the first position and not including the second position and the third position than when the travel position is in a second range including the second position and outside the first range or when the travel position is in a third range including the third position and outside the first range and outside the second range.

A haptic method for a haptic device, the haptic device including:

• an operation part capable of being operated to rotate;
• a detection part configured to detect a rotation position of the operation part;
• a biasing part capable of biasing the operation part along a rotation direction of the operation part;
• a signal generation part configured to generate a drive signal for driving the biasing part based on the rotation position;
• and
• a low-pass filter part configured to output the drive signal to the biasing part by attenuating a high-frequency component of the drive signal,
• the haptic method comprising:
• when the rotation position is located between a first position and a second position that is on one side of the first position in the rotation direction, causing the signal generation part to generate the drive signal for causing the biasing part to perform biasing to the other side in the rotation direction;
• when the rotation position is located between the first position and a third position that is on the other side of the first position in the rotation direction, causing the signal generation part to generate the drive signal for causing the biasing part to perform biasing to the one side;
• and
• causing the low-pass filter part to attenuate the high-frequency component of the drive signal more strongly when the rotation position is in a first range including the first position and not including the second position and the third position than when the rotation position is in a second range including the second position and outside the first range, or when the rotation position is in a third range including the third position and outside the first range and outside the second range.
