Abstract
A method improves performance of a computer that provides binaural sound to a listener. A memory stores coordinate locations that follow a path of how the head of the listener moves. This path is retrieved in anticipation of subsequent head movements of the listener to improve computer performance of executing binaural sound.
Claims20
A method comprising:
- processing sound to generate binaural sound that localizes to a virtual image displayed to a listener with a wearable electronic device (WED) worn on a head of the listener;
- tracking movements of the head of the listener;
- and
- improving performance of the processing by prefetching and caching head-related transfer functions (HRTFs) for the movements of the head of the listener.
1 more element
An electronic device, comprising:
- a cache memory;
- and
- one or more processors that processes sound into binaural sound that localizes to a virtual sound source for a listener with a head orientation, wherein performance of the processor improves by prefetching and caching head-related transfer functions (HRTFs) into the cache memory with the HRTFs having coordinates for where the virtual sound source will move.
A method comprising:
- displaying a virtual image to a listener that localizes binaural sound to the virtual image;
- and
- improving performance of processing the binaural sound by prefetching and caching head related transfer functions (HRTFs) corresponding to a path the virtual image will move.
