Abstract: A control apparatus for controlling a thermal sensation providing device that provides a thermal sensation to an object coming in contact with a virtual material includes a database configured to store first information indicative of a relationship between a type of virtual material and a speed of a temperature change during a first period that starts at a commencement of providing the thermal sensation and that ends at a lapse of a first time length from the commencement, and a temperature control unit configured to control a temperature provided by the thermal sensation providing device during the first period based on the first information.

Abstract: A door handle, to be attached to a door, includes an outer case, an inner case integrated with the outer case, and a pressure detector configured to detect pressure applied to the inner case. The inner case includes a recess in proximity to an end portion in a longitudinal direction, and the pressure detector detects a displacement of a first inner wall surface on a center portion side of the inner case in the recess, caused by the pressure applied to the inner case.

Abstract: A tactile sensation providing apparatus includes a linear resonant actuator; and circuitry configured to provide a pulse wave to the linear resonant actuator as a driving signal. The circuitry is further configured to, when a frequency of the pulse wave is smaller than a resonance frequency of the linear resonant actuator, set a pulse width of the pulse wave at a value smaller than a half of a reciprocal of the frequency of the pulse wave.

Abstract: A controller controls a temperature sensation provider that provides temperature sensations to an object contacting a contact surface of the temperature sensation provider. The controller includes a database including control information that associates values of a temperature of the contact surface with values of a controlled variable of the temperature sensation provider for each of the temperature sensations, and a temperature controller that controls the temperature sensation provider based on a measured temperature of the contact surface, a temperature sensation to be provided, and the control information.

Abstract: An input device includes an operation panel, a frame disposed on a back side of the operation panel, a pressure detector disposed between the operation panel and the frame, and an elastic part. The pressure detector includes a lever including a deformation part that warps when a pressing force is applied, a protruding part provided on a first surface of the deformation part, and a surrounding wall provided on a periphery of a second surface of the deformation part; and a pressure detection element that is disposed in a region of the second surface of the deformation part surrounded by the surrounding wall, warps along with the deformation part, and outputs a pressure detection signal corresponding to the pressing force. The elastic part is disposed between the protruding part or the surrounding wall and the frame or the operation panel and applies a pre-pressure to the deformation part.
