Abstract: An input device includes a sensor that detects a degree of proximity of an object in each of one or more detection regions on an operation surface, generates one or more sets of detection data corresponding to the detection result for each of the detection regions, and thereby generates N sets of the detection data in total; and an element data generator that generates, based on the N sets of the detection data, M (M is a natural number greater than N) sets of element data indicating degrees of proximity of the object in M sections that virtually divide the operation surface. The element data generator is configured to repeat a data generation process at least two times.

Abstract: A capacitance detection device includes a first voltage output circuit configured to output a first alternating current voltage supplied to a shield electrode provided proximate to a detection electrode, a second voltage output circuit configured to output a second alternating current voltage whose frequency and phase are the same as that of the first alternating current voltage and whose amplitude is less than that of the first alternating current voltage, and a current output circuit configured to output a driving current Is to the detection electrode so that the difference between the voltage of the detection electrode and the second alternating current voltage becomes smaller, and output a detection signal corresponding to the driving current. The second voltage output circuit outputs a second alternating current voltage whose amplitude is adjusted so that the driving current in the absence of the object proximate to the detection electrode.

Abstract: An operation device includes a movable part having an operating surface on which a contact operation is performed by an living body, a vibration exciter attached to the movable part at a position other than the operating surface, and configured to excite the movable part in a first direction along the operating surface, and in a second direction intersecting the operating surface, a base part, and an elastic support, provided between the movable part and the base part, and configured to elastically support the movable part with respect to the base part. The movable part provides a tactile sensation to the living body making the contact operation when excited in the first direction by the vibration exciter, and generates a sound from the operating surface when excited in the second direction by the vibration exciter.

Abstract: An input device includes an operation panel member with an operation surface; a support member contacting a side face of the operation panel member to support the operation panel member, the side face being perpendicular to the operation surface of the operation panel member; and an actuator configured to vibrate the support member in a direction parallel to the operation surface. The support member contacts the operation panel member only at the side face, and the operation panel member vibrates in a direction parallel to the operation surface by transmission of a vibration of the support member from the side face to the operation panel member.

Abstract: A data configuration process is repeatedly performed at least twice, and a sum of a value obtained by multiplying a difference between a first temporary value (PAjt=1) of element data obtained by the first data configuration process and a second temporary value (PAjt=2) of the element data obtained by the second data configuration process by a predetermined proportionality coefficient γ and the first temporary value (PAjt=1) is calculated for each of M sections A1 to AM as values approximated to a convergence value of the element data. By this, the number of times the data configuration process is repeatedly performed is considerably reduced when compared with a case where a convergence value of element data is obtained by repeatedly performing the data configuration process a number of times.
