Abstract: A system where application programs can be programmed and accessed with input/output device independent, generic functional commands. A shared memory structure (200) allows the translation of device specific commands to device independent, generic functional commands. The system provides a multi-dimensional user oriented synthetic environment with a craft (400) surrounding the user to provide a visual reference and motion parallax cues enabling the user to better appreciate distances and directions within the synthetic environment. The system provides the display of the craft in close proximity to the user's point of perspective without substantially degrading the image resolution of the displayed environment.
