Abstract
A wearable electronic device (WED) worn on a head of a user displays a virtual image that has sound. One or more processors process the sound for the virtual image into binaural sound for the user. The binaural sound has a sound localization point (SLP) with a coordinate location that occurs behind the virtual image while the image is located a near-field distance from the head of the user.
Claims20
A method, comprising:
- displaying, with a wearable electronic device (WED) worn on a head a user, a virtual object that appears within a near-field distance from the user;
- and
- processing, with one or more processors in the WED, sound for the virtual object to generate binaural sound that has a sound localization point (SLP) with a coordinate location at a far-field distance from the user that occurs along a line-of-sight from the user to the virtual object and behind the virtual object while the virtual object is within the near-field distance from the user.
A wearable electronic device (WED) worn on a head of a user, the WED comprising:
- a display that displays a virtual image that occurs within a near-field distance from the head of the user;
- and
- a digital signal processor (DSP) that processes sound for the virtual image with far-field head-related transfer functions (HRTFs) to generate binaural sound that has a sound localization point (SLP) that occurs at a far-field distance located behind the virtual image and along a line-of-sight from the user to the virtual image while the virtual image is located within a near-field distance from the head of the user.
A wearable electronic device (WED) worn on a head of a user, the WED comprising:
- a display that displays a virtual image that is located within a near-field distance from the head of the user viewing the virtual image;
- and
- one or more processors that process sound for the virtual image with head-related transfer functions (HRTFs) to generate binaural sound that has a sound localization point (SLP) with a coordinate location that occurs at a far-field distance located behind the virtual image along a line-of-sight from the user to the virtual image while the display displays the virtual image to the user at the near-field distance, wherein the coordinate location of the binaural sound continues to occur at the far-field distance located behind the virtual image when the head of the user moves while the virtual image remains within the near-field distance from the head of the user.
