Abstract
An interface device includes an on-panel pad and a sensor controller. The interface device is used to perform an input to an electronic device in response to an operation by a user on a capacitive touch panel display of the electronic device. The on-panel pad causes sensor electrodes included in the touch panel display to generate a two-dimensional pattern of capacitance while the on-panel pad is on the touch panel display. When the two-dimensional pattern generated while the on-panel pad is on the touch panel display has been detected, the sensor controller generates or outputs data including operation information in response to a change in capacitance in a region that is associated with the two-dimensional pattern and that receives an operation of the on-panel pad, the operation information indicating an operation state of the on-panel pad.
