When an application displays an image extending over display units (110-1, 110-2), a coordinate transformation unit (120) transforms physical coordinates indicating the positions, at which touches on the display units (110-1, 110-2) are sensed, to virtual coordinates using a predetermined calculation, and outputs the virtual coordinates.
