A display is described that provides a three-dimensional perspective view with spatially correlated audio. The system is developed around an optics device that projects a three-dimensional perspective view from a CRT to a concave mirror that focuses the energy at an image plane above the mirror. The result is that the objects displayed on the CRT appear to be floating in space. The directional audio is provided from an audio localization cue synthesizer that encodes pinna filtering and an interaural time delay onto an input audio signal. A magnetic head tracker is used to keep the audio images stable. The optical system is presented along with the graphics methods that were used to generate the visual cues. Then the audio localization cue synthesizer is described with emphasis on using this device to provide spatialized audio for use in synthetic environments.
