Abstract

Systems, apparatuses and methods may provide away to render augmented reality (AR) and/or virtual reality (VR) sensory enhancements using ray tracing. More particularly, systems, apparatuses and methods may provide a way to normalize environment information captured by multiple capture devices, and calculate, for an observer, the sound sources or sensed events vector paths. The systems, apparatuses and methods may detect and/or manage one or more capture devices and assign one or more the capture devices based on one or more conditions to provide observer an immersive VR/AR experience.

calculate, for the observer, ray tracing vector paths of sound sources or sensed events, wherein the ray tracing vector paths include vector path attributes that include one or more of positional information and directional information relative to the observer;
generate a number of ray bundles for the sounds, wherein the ray bundles include a number of frequency bands wherein the number of ray bundles include a number of audio bands for sounds with dialogue type acoustic effects; and
play back the normalized environment information to the observer as augmented reality sensory enhancements (AR) or virtual reality (VR) sensory enhancements based on the ray tracing vector paths.

2. The system of claim 1 , wherein the number of ray bundles include a number of surround sound bands for surround sound type acoustic effects.

3. The system of claim 1 , the ray tracing engine further to:
adjust the number of frequency bands within the ray bundles based on acoustic properties of one or more of the sound sources.

4. The system of claim 1 , wherein the environment information is captured by one or more capture devices for multiple n-dimensional environments, the environment information including one more of sounds from one or more sound sources or sensed events from one or more event sources, wherein, during the playing back of the environment information, the ray tracing engine is to attenuate at least one of the sounds to produce a surround sound experience for the observer based on the superposition of the ray bundles, wherein normalizing the environment information includes determining, by at least one of the capture devices, the position of the observer, and wherein the operating parameters include one or more of user preferences, application parameters, or performance parameters.

5. The system of claim 4 , the ray tracing engine further to:
superimpose the ray bundles to the visual information presented during playback, and wherein attenuating at least one of the sounds is based on the superposition of the ray bundles, produces a ray trace Doppler effect for the observer, by applying a relative motion filter to the normalized environment information.

8. The system of claim 4 , further comprising a capture device manager to:
detect, for the capture devices, one or more of a capture device mode of operation, capture device capabilities, or a change to the capture device mode or a change to the capture device capabilities based on one or more operating parameters;
assign one or more of the capture devices to capture at least a first microphone of the microphones to a first sound of the sounds or a first sensor of the sensors to a first sensed event of the sensed events based on one or more of the user preferences, the application parameters, attributes of the first sound or the first sensed event, the location or direction of travel the sound source of the first sound; and

10. The system of claim 1 , the ray tracing engine further to:
apply two or more of an absorption filter, an attenuation filter, and a reflective filter to the normalized environment information to form filtered normalized environment information associated with acoustic properties of objects and surfaces, based on attributes of the ray tracing vector paths of the sound sources or sensed events.

11. An apparatus comprising:
a memory comprising environment information; and
a graphics pipeline apparatus comprising:
