More Information
Summary:An input device includes a top panel having an operation surface, a detection unit configured to detect a capacitance corresponding to a distance between the operation surface and an object, and a controller configured to determine, based on a detection result from the detection unit, a relative state between the operation surface and the object to be one out of a non-detection state and a plurality of states. The controller measures, for each of the plurality of states, a duration in which the capacitance is greater than or equal to a corresponding one of capacitance thresholds set for the plurality of states, and determines, using the durations and the time thresholds and capacitance thresholds set for the plurality of states, the relative state to be one out of the non-detection state and the plurality of states.
