A device includes a display panel configured to display an interface. The device includes a motion sensor configured to detect a motion of the device and to output a detection signal in response to the detection of the motion. The device includes circuitry configured to control, based on the detection signal, the display panel such that at least one of a display position and a display size of an element displayed in the interface changes, wherein when the motion includes a physical shock on the device, the detection signal includes an indication of a hitting position corresponding to a position on the device where the physical shock is detected by the motion sensor, and the circuitry controls the display panel such that the at least one of the display position and the display size of the element changes based on the hitting position.
