Abstract
Systems and methods are provided for rendering of a dual eye-specific display. The system tracks the user's eye movements and/or positions, in some implementations, based on electroencephalography (EEG) of the user, to correctly label the central (foveal) and peripheral (extra-foveal) areas of the display. Foveal data is fully rendered while extra-foveal data is reduced in resolution and, in some implementations, shared between the two displays.
Claims20
A head-mounted display device with eye-tracking of a user's two eyes, comprising:
- a first display for the left eye;
- a second display for the right eye;
- a memory, coupled to the first display and the second display, comprising a first frame buffer for the first display and a second frame buffer for the second display, wherein the first frame buffer comprises a first foveal frame buffer and a first extra-foveal frame buffer and the second frame buffer comprises a second foveal frame buffer and a second extra-foveal frame buffer;
- and
- one or more processors, coupled to the memory, configured to:
- receive eye-tracking information of the user wearing the head mounted display, wherein the eye-tracking information comprises at least one of an eye movement and an eye position of the user,
- determine, based on the eye-tracking information, a first foveal region of the first display, a first extra-foveal region of the first display, a second foveal region of the second display, and a second extra-foveal region of the second display, and
- load, into the memory, first foveal region pixels of the first foveal region, first extra-foveal region pixels of the first extra-foveal region, second foveal region pixels of the second foveal region, second extra-foveal region pixels of the second extra-foveal region,
- wherein:
- the first foveal region pixels are represented with full resolution and loaded into the first foveal frame buffer,
- the first extra-foveal region pixels are represented with reduced resolution and loaded into the first extra-foveal frame buffer,
- the second foveal region pixels are represented with full resolution and loaded into the second foveal frame buffer, and
- the second extra-foveal region pixels are represented with reduced resolution and loaded into the second extra-foveal frame buffer.

- loading, into a first foveal frame buffer of a first frame buffer for the first display, first foveal region pixels that are represented with full resolution of the first foveal region;
- loading, into a first extra-foveal frame buffer of the first frame buffer for the first display, first extra-foveal region pixels that are represented with reduced resolution of the first extra-foveal region;
- loading, into a second foveal frame buffer of a second frame buffer for the second display, second foveal region pixels that are represented with full resolution of the second foveal region;
- and
- loading, into a second extra-foveal frame buffer of the second frame buffer for the second display, second extra-foveal region pixels that are represented with reduced resolution of the second extra-foveal region.

A non-transitory computer readable medium storing a computer-readable program for a head mounted display device with eye-tracking of a user's two eyes, comprising
- computer-readable instructions to receive eye-tracking information of the user wearing the head mounted display, wherein the eye-tracking information comprises at least one of an eye movement and an eye position of the user;
- computer-readable instructions to determine, based on the eye-tracking information, a first foveal region of a first display for the left eye, a first extra-foveal region of the first display, a second foveal region of a second display for the right eye, and a second extra-foveal region of the second display;
- and
- computer-readable instructions to load, into a first foveal frame buffer of a first frame buffer for the first display, first foveal region pixels that are represented with full resolution of the first foveal region;
- computer-readable instructions to load, into a first extra-foveal frame buffer of the first frame buffer for the first display, first extra-foveal region pixels that are represented with reduced resolution of the first extra-foveal region;
- computer-readable instructions to load, into a second foveal frame buffer of a second frame buffer for the second display, second foveal region pixels that are represented with full resolution of the second foveal region;
- and
- computer-readable instructions to load, into a second extra-foveal frame buffer of the second frame buffer for the second display, second extra-foveal region pixels that are represented with reduced resolution of the second extra-foveal region.
