Abstract: A screen display apparatus includes an operation information reception unit that receives operation information regarding an inclination direction and an inclination angle of a joystick from the joystick, and a screen controller that performs a scroll process for scrolling a screen and a zoom process for zooming based on the operation information. The screen controller scrolls the screen according to the inclination direction and the inclination angle of the joystick, and continues a zoom-out process for zooming-out of the screen based on a detection of the inclination angle that is greater than a predetermined angle for a predetermined period until detecting the inclination angle of the joystick to be equal to or smaller than the predetermined angle or until zooming out to a predetermined minimum zoom rate.

Abstract: A map display controller displays a three-dimensional map image on a display screen of a display device, and superimposes a route wall standing from a route and along the route in the three dimensional map image on the display device. This reduces a difficulty in confirming the route behind structures such as a building in the three-dimensional map image displayed on the display screen.

Abstract: In a display screen of an image display device, plural menu items in a higher rank menu hierarchy are displayed in a first circular arrangement, and plural menu items in a lower rank menu hierarchy that is subsidiary to the higher rank menu hierarchy is displayed in a second circular arrangement that concentrically surrounds the first circular arrangement with a greater diameter than the first circular arrangement. In addition, a pointed-out portion in the display screen is identified according to a user operation to an operation device, and a function of a menu item in the lower rank menu hierarchy being in association with the identified pointed-out portion is realized by a processing for the function. Each of the menu items in the lower rank menu hierarchy is arranged in a position in a manner that expresses the subordination of the lower rank menu item to one of the menu items in the higher rank menu hierarchy.

Abstract: A sound data retrieval support device includes an operation receiving unit, a sound output unit, and a control unit. The sound data retrieval support device supports the user in retrieving a desired sound data item among a plurality of sound data items. The each of the plurality of sound data items is associated with a location and a sound field in the virtual space based on attribute information items of the sound data item. The control unit causes a search point to be moved in the virtual space based on the operation command received via the operation receiving unit. The control unit causes the sound output unit to output sound that corresponds to one of the plurality of sound data items. The search point is located in the sound field of the one of the plurality of sound data items.
