3D AUDIO DELIVERY ACCOMPANYING 3D DISPLAY SUPPORTED BY VIEWER/LISTENER POSITION AND ORIENTATION TRACKING
Techniques are described herein for supporting 3D audio delivery accompanying 3D display supported by viewer/listener position and orientation tracking. For example, audio content is configured to have a spatial orientation that accords with an orientation of a viewer. A spatial orientation of audio content is a configuration of the audio content in which characteristics of respective portions of the audio content, which correspond to respective speakers, indicate an orientation of ears of a viewer/listener with respect to sound source(s) that correspond to (e.g., are depicted in) a three-dimensional view. Such a characteristic may include an amplitude of sound that corresponds to a sound source and/or a delay associated with the sound that corresponds to the sound source.

identifying at least one positional characteristic relating to the first orientation of the viewer within the premises;
delivering a video output, tailored based at least in part on the at least one positional characteristic, for the three-dimensional visual presentation to the viewer in the first orientation; and
delivering an audio output, tailored based at least in part on the at least one positional characteristic, to audibly supplement the video output for the viewer in the first orientation.
2 . The method of claim 1 , wherein the at least one positional characteristic comprising a relative location of the viewer.
