Abstract
An information input device includes a plurality of sensors arranged for an operation surface at predetermined intervals, each sensor detecting contact of an operation object with the operation surface in a vicinity of the sensor and outputting a detection signal. An input sensing judgment unit determines whether an input of the operation object is sensed based on an integrated detection signal of the plurality of sensors. A sensor group selection unit selects a sensor group including sensors having sensed the operation object from among the plurality of sensors based on detection signals of the sensors. A sensor specifying unit specifies the sensors having sensed the operation object from the selected sensor group based on the detection signals of the sensors. A position detecting unit detects a position of the operation object on the operation surface based on the detection signals of the specified sensors.
