摘要： Techniques and architectures may involve operating a wearable device, such as a head-mounted device, which may be used for virtual reality applications. A processor of the wearable device may operate by dynamically tracking the precise geometric relationship between the wearable device and a user's eyes. Dynamic tracking of eye gaze may be performed by calculating corneal and eye centers based, at least in part, on relative positions of points of light reflecting from the cornea of the eyes.

摘要： The techniques discussed herein may facilitate real-time computation and playback of a propagated signal(s) perceived at a listener location in a three-dimensional environment in response to reception of a desired anechoic signal at a source location in the three-dimensional environment. The propagated audio realistically accounts for dynamic signal sources, dynamic listeners, and effects caused by the geometry and composition of the three-dimensional environment. The techniques may parameterize impulse response(s) of the environment and convolve the anechoic signal with canonical filters at run-time in a manner that respects the parameters of the parameterized impulse response(s). The techniques also provide for real-time computation and playback of a propagated audio signal perceived at a listener location in a virtual three-dimensional environment responsive to generation of source audio signals generated at multiple source locations in the virtual three-dimensional environment.
