Abstract
A screen is provided on a housing in such a manner that the screen protrudes toward its nearer side, and is inclined so that the nearer side becomes lower. This screen displays thereon a first hierarchy menu for indicating an arrangement of genre pictures, a second hierarchy menu for indicating an arrangement of commodity pictures, and a map image for indicating a map of the sales counters. A user brings his or her hand tip nearer to this screen. This operation allows a double-ring pointer to be displayed at a position which corresponds to the spatial position or direction of the user's hand tip relative to the screen. On this screen, the user is permitted to change the position of this double-ring pointer by performing a gesture of changing the spatial position or direction of the user's hand tip.
