Abstract
A tabletop display device includes a flat panel display for displaying an image, light emitting units arranged along a periphery of the flat panel display to emit light toward an inner side and an outer side of the periphery and light receiving units arranged along the periphery to receive light incident from the inner side and the outer side of the periphery. The tabletop display device further includes a control unit for detecting a user's position based on light emitted from at least one of light emitting units and received from the outer side of the periphery by at least one of the light receiving units and for determining a touch position of the flat panel display based on light emitted from at least one of the light emitting units and received from the inner side of the periphery by at least one of the light receiving units.
