Abstract:
1. An information processing apparatus comprising: a key array having a key layout in which a plurality of rows of input keys parallel to a first direction are arranged in a second direction orthogonal to the first direction and input keys belonging to a first row in the plurality of rows are arranged to be shifted in the first direction with respect to input keys belonging to a second row in the plurality of rows; a plurality of first wiring electrodes that are routed between the input keys at intervals in the first direction and each having a capacitance changed by a proximity of a detection target; a plurality of second wiring electrodes that are routed along the first direction to thread through the plurality of rows of the input keys and each having a capacitance changed by the proximity of the detection target; and a control unit configured to generate a control signal including a first signal on a position of the detection target along the first direction based at least in part on the capacitances of the plurality of first wiring electrodes, the capacitances of the plurality of second wiring electrodes, and a shift amount of the input keys in each of the rows in the first direction.
