Abstract
An electrostatic coordinate input device includes: a plurality of sensor electrodes disposed on the rear surface side of a manipulation surface; a measuring circuit that measures a capacitance between each of the plurality of sensor electrodes and an indicating body, with which a manipulation input is performed; and a calculating unit that calculates the coordinate of the indicating body according to a plurality of capacitances measured by the measuring circuit. The calculating unit repeatedly executes first calculation processing, in which the calculating unit measures the coordinate of the indicating body from the plurality of capacitances and then calculates an average moving speed of the indicating body according to the measured coordinate of the indicating body, as well as second calculation processing. In the second calculation processing, an average is calculated between a predicted coordinate and the measured coordinate of the indicating body, as the coordinate of the indicating body.
