Abstract: A haptic output apparatus includes a vibration system having one or more resonance frequencies, the vibration system including an actuator configured to vibrate in accordance with an input signal, and including an object coupled to the actuator and configured to be excited in response to the vibration of the actuator. The haptic output apparatus includes a controller configured to control driving of the actuator. The controller corrects a drive signal using at least one correction model to output the corrected drive signal to the actuator as the input signal, the correction model being preliminarily generated based on the resonance frequencies. Alternatively, the controller outputs a control signal to the actuator as the input signal, the control signal being preliminarily generated using the correction model.

Abstract: An input device includes a first part and a second part configured to move relative to each other according to an input operation, a magnetic viscous fluid whose viscosity changes according to a magnetic field, and a magnetic-field generator that generates the magnetic field applied to the magnetic viscous fluid. The second part includes a first surface and a second surface that are arranged in a direction orthogonal to a direction of relative movement between the first part and the second part. Gaps are formed between the first surface and the first part and between the second surface and the first part, and the magnetic viscous fluid is present in at least a part of the gaps.

Abstract: An electromagnetic drive device includes a permanent magnet attached to a surface of a first yoke facing a second yoke; and first and second excitation coils to generate magnetic flux when being energized. The second yoke includes a base, and a first protruding part protruding from the base toward the first yoke, between the first and second excitation coils. The permanent magnet includes a first region; and second and third regions positioned on respective sides of the first region. The first region is magnetized to be a first pole, and the second region and the third region are magnetized to be second poles. The first region is opposite to the first protruding part, a boundary between the first and second regions is opposite to the first excitation coil, and a boundary between the first and third regions is opposite to the second excitation coil.

Abstract: An input device includes an operation member, an actuator configured to impart a tactile effect to the operation member, and a controller configured to apply, to the actuator, a control signal for starting to apply a first vibration to the operation member at a first timing and for starting to apply a second vibration to the operation member at a second timing after the first timing, such that a combined vibration of the first vibration and the second vibration is applied to the operation member. The controller is configured to change a duration of a first period of the combined vibration to two or more different durations of the first period by changing a control period of time that extends from the first timing to the second timing to two or more different control periods of time.
