  • Support Based 3D Navigation
    Publication number: 20170352188
    Abstract: A portable display device is operative to modulate the appearance of a real or virtual image in response to the motion of the display device with respect to its relative movement with respect the object's virtual position. The display in effect becomes a portable window into a virtual world. The virtual object can be created from a real object by image capture and can be 2 or 3 dimensional. Specific modes of display movement can be used to infer a relative movement of the display window with respect to the one or more objects in the virtual world.

  • Method and apparatus for creating sounds in a virtual world by simulating sound in specific locations in space and generating sounds as touch feedback
    Patent number: 5587936
    Abstract: A method and apparatus for creating sounds in a virtual world. The system provides signal processing capabilities to convert monaural sounds to fully spacialized sound sources. A user of the system wearing a pair of stereo headphones perceives live, computer generated, or recorded sounds as coming from specific locations in space, just a listener does in the real world.
