Abstract: An image taken of a three-dimensional virtual space including a virtual designating object and an object arranged therein is displayed. When the position of the virtual designating object does not coincide with the object, the virtual designating object is arranged in a predetermined orientation. The position of the virtual designating object is determined based on an acquired designated position on a two-dimensional image, which is generated from the three-dimensional virtual space taken by a virtual camera. When the position of the virtual designating object corresponds to the object, the displayed orientation of the virtual designating object is based on the position.

Abstract: An image taken of a virtual space including a user-operable child object and user-inoperable furniture object is stereoscopically displayed on a screen of a stereoscopic image display device. On the other hand, an image taken, of the same virtual space, from the same direction is displayed in a planar manner on a screen of a planar image display device. On the screen of the planar image display device, a child object image, in which a silhouette of the child object displayed on the stereoscopic image display device is displayed. A user touches on the screen of the planar image display device, while seeing the child object displayed on the stereoscopic image display device, thereby operating the child object.

Abstract: A free direction input area, a lateral direction input area, and a longitudinal direction input area are provided on an input surface of a touch panel. When a user performs a slide operation whose starting point is within the free direction input area, movement of a virtual camera is controlled based on a change amount of a touch position with respect to X- and Y-axis directions. When the user performs a slide operation whose starting point is within the lateral direction input area, movement of the virtual camera is controlled based on a change amount of a touch position only with respect to the X-axis direction. When the user performs a slide operation whose starting point is within the longitudinal direction input area, movement of the virtual camera is controlled based on a change amount of a touch position only with respect to the Y-axis direction.
