Abstract

An information handling system (IHS) controls a display for an immersive experience based upon a gazing view of a user. A processor communicates with the display and a gaze detector to detect a relative location of a user to the display. A graphic processing unit (GPU) allocates a field of view on the display based upon the relative location, centers display content in the field of view on the display, and accesses color point control data in response to the allocated field of view. The GPU manages color and brightness of display components of the display according to the accessed color point control data to compensate for variations of color and brightness in a viewing angle of the field of view.

Claims

1. An information handling system (IHS) comprising:

a display comprising an array of more than one display panel each comprising a gaze detection sensor;

a gaze detector that synthesizes information from the gaze detection sensors to detect the relative location of the user;

a processor that communicates with the display and the gaze detector to;

detect a relative location of a user to the display; and

a graphic processing unit (GPU) that communicates with the processor and the display to;

allocate a field of view on the display based upon the relative location;

center display content in the field of view on the display;

access color point control data in response to the allocated field of view; and

manage color and brightness of display components of the display according to the accessed color point control data to compensate for variations of color and brightness in a viewing angle of the field of view.

2. The IHS of claim 1, wherein:

the gaze detector comprises a three-dimensional camera to produce a three-dimensional camera image; and

the processor detecting the relative location of the user comprises the processor detecting the user within the three-dimensional camera image.

3. The IHS of claim 1, wherein the processor detects the relative location of the user by:

detecting more than one candidate user within a viewing area of the display;

querying the more than one candidate user to indicate which one candidate is to be deemed as defining the field of view; and

receiving confirmation from the user of the more than one candidate user as having the field of view.

4. The IHS of claim 1, wherein the processor detects the relative location of the user by:

detecting relative locations of more than one candidate user within a viewing area of the display; and

determining a compromise location between the relative locations by three dimensionally averaging the relative locations of the more than one candidate user.

5. The IHS of claim 1, wherein the processor detects the relative location of the user by receiving a communication signal from a portable communication device that is being worn or carried by the user.

6. The IHS of claim 1, further comprising one or more microphones that detect an angular direction to an audio source, wherein the processor is electronically connected to the one or more microphones and detects the relative location of the user by receiving the angular direction based on a verbal utterance from the user that is detected by the one or more microphones.

7. The IHS of claim 1, further comprising a measuring device that:

maps color shift and brightness of pixel display components of the display as a function of viewing angle; and

generates more than one three-dimensional (3D) look up table (LUT) of compensation values for color management of the pixel display components, wherein each 3D LUT corresponds to a selected viewing angle and one of the 3D LUT comprises the accessed color point control data that is associated with the selected viewing angle of the allocated field of view.

8. The IHS of claim 1, wherein the display comprises a curved display panel and the GPU manages color and brightness of display components, while taking a curvative and direct viewing of the curved display panel into consideration to make a correction.

9. A computer-implemented method of controlling a display for an immersive experience based upon a gazing view of a user, the method comprising:

a processor communicating with a gaze detector for detecting a relative location of a user to a display, the display comprising an array of more than one display panel each comprising a gaze detection sensor, wherein the gaze detector synthesizes information from the gaze detection sensors to detect the relative location of the user; and

a graphic processing unit;

allocating a field of view on the display based upon the relative location;

centering display content in the field of view on the display;

accessing color point control data in response to the allocated field of view; and

managing color and brightness of display components of the display according to the accessed color point control data to compensate for variations of color and brightness in a viewing angle of the field of view.

10. The method of claim 9, wherein the processor detecting the relative location of the user comprises detecting the user within a three-dimensional camera image.

11. The method of claim 9, wherein the processor detecting the relative location of the user comprises:

detecting more than one candidate user within a viewing area of the display;

querying the more than one candidate user to indicate which one candidate is to be deemed as defining the field of view; and

receiving confirmation from the user of the more than one candidate user as to having the field of view.

12. The method of claim 9, wherein the processor detecting the relative location of the user comprises:

detecting relative locations of more than one candidate user within a viewing area of the display; and

determining a compromise location between the relative locations by three dimensionally averaging the relative locations of the more than one candidate user.

13. The method of claim 9, wherein the processor detecting the relative location of the user comprises receiving a communication signal from a portable communication device that is being worn or carried by the user.

14. The method of claim 9, wherein the processor detecting the relative location of the user comprises:

one or more microphones detecting an angular direction to an audio source; and

the processor that is electronically connected to the one or more microphones detects the relative location of the user by receiving the angular direction based on a verbal utterance from the user that is detected by the one or more microphones.

15. The method of claim 9, further comprising:

a measuring equipment mapping color shift and brightness of pixel display components of the display as a function of viewing angle; and

the measuring equipment generating more than one three-dimensional (3D) look up table (LUT) of compensation values for color management of the pixel display components, each 3D LUT corresponding to a selected viewing angle and one of the 3D LUT comprises the accessed color point control data that is associated with the selected viewing angle of the allocated field of view.

16. The method of claim 9, wherein the display comprises a curved display panel.
