3D audio delivery accompanying 3D display supported by viewer/listener position and orientation tracking

Abstract

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.

Problems solved by technology

Problems exist with such techniques for viewing three-dimensional images.

For instance, persons that use such displays and systems to view three-dimensional images may suffer from headaches, eyestrain, and / or nausea after long exposure.

Furthermore, some content, such as two-dimensional text, may be more difficult to read and interpret when displayed three-dimensionally.

A disadvantage of parallax barriers is that the viewer must be positioned in a well-defined location in order to experience the three-dimensional effect.

If the viewer moves his / her eyes away from this “sweet spot,” image flipping and / or exacerbation of the eyestrain, headaches and nausea that may be associated with prolonged three-dimensional image viewing may result.

However, surround sound has its limitations, especially when applied with respect to three-dimensional display devices.

For example, if a viewer moves away from the fixed location, a degradation of the viewer's audio experience may result.
