  • Patent number: 11178384
    Abstract: A game system that is a non-limiting example information processing system is attached to a goggle device, and generates and displays a left-eye image and a right-eye image on a display. When starting a game application that a plurality of individual games can be selectively played, a menu image is displayed on the display. A plurality of icons each relating to each of the plurality of individual games are arranged at predetermined positions in a virtual space for displaying the menu image. A virtual camera arranged at a predetermined position in the virtual space changes a posture thereof so as to correspond to a posture change of a main body apparatus in a real space, thereby to control a direction of a line-of-sight of the virtual camera. If an icon is included in a field of view of the virtual camera when a user depresses a predetermined button, predetermined processing relevant to the icon is performed.
