A menu screen includes multiple buttons. Assigned to each button for each direction is another button to which an anchor is moved according to a directional user input of up, down, right or left. A button B and a button C both located downstream of a button A are candidates to which the anchor is moved when the down direction key is input with the anchor pointing to the button A. Scores of positional relationships of the position between points of the shortest distance from an anchor position of the button A within the range of the button B and the button C to the anchor position are calculated. According to the calculated scores, the next destination of the anchor when the down direction key is input with the anchor pointing to the button A is set to either button B or button C.
