Abstract: In order to allow key input without operation of a keyboard or allow click and drag operations by finger tips of the hands, the present invention is primarily characterized in that a user wears a glove (7) (including a glove that covers only finger tips), which has a motion detection sensor (4) (based on the same principle as a laser mouse or an optical mouse) and a tactile sensor (5) (a conductive rubber, a piezoelectric element or the like) mounted on each finger-tip part thereof, on each hand (like mounting a small laser mouse or optical mouse on each finger tip), motion information about each finger tip is transmitted to an information processing device, such as a personal computer (PC), a PDA and a cellular phone, the position of each finger tip is displayed on a virtual keyboard (2) shown on a display (3) of the information processing device, and the tactile sensor (5) detects the pressure on a finger tip when the finger tip is pressed against an arbitrary object, such as a desk, thereby allowing input
