Abstract

An embodiment of an electronic processing system may include an application processor, persistent storage media communicatively coupled to the application processor, a graphics subsystem communicatively coupled to the application processor, a sense engine communicatively coupled to the graphics subsystem to provide sensed information, a focus engine communicatively coupled to the sense engine and the graphics subsystem to provide focus information, a motion engine communicatively coupled to the sense engine, the focus engine, and the graphics subsystem to provide motion information, and a motion biased foveated renderer communicatively coupled to the motion engine, the focus engine, the sense engine to adjust one or more parameters of the graphics subsystem based on one or more of the sense information, the focus information, and the motion information. Other embodiments are disclosed and claimed.

First claim

What is claimed is:

1. At least one non-transitory computer readable storage medium comprising a set of instructions, execution of which by a graphics apparatus causes the graphics apparatus to:
associate a first image portion with a focus area of an image based on eye-tracking information;
cause the first image portion to be rendered at a first rate;
cause a second image portion to be rendered at a second rate, wherein the second image portion is a region outside of the first image portion, and wherein the second rate is different from the first rate;
associate a third image portion with a relocation of the focus area of the image based on a change in the eye-tracking information; and
cause an adjustment to a size of the focus area, wherein the size of the focus area is to be adjusted based on at least one of a workload amount for the graphics apparatus or scene content.

2. The at least one non-transitory computer readable storage medium of claim 1 , wherein before adjustment the focus area is a first shape, and after adjustment the focus area is a second shape, and wherein the first shape is one of a circular shape or an elliptical shape.

3. The at least one non-transitory computer readable storage medium of claim 2 , wherein the second shape is an elliptical shape.

4. The at least one non-transitory computer readable storage medium of claim 1 , wherein the first rate is higher than the second rate.

5. The at least one non-transitory computer readable storage medium of claim 1 , comprising further instructions, execution of which by the graphics apparatus causes the graphics apparatus to cause the third image portion to be rendered at the first rate.

6. The at least one non-transitory computer readable storage medium of claim 1 , wherein the adjustment to the size of the focus area results in an increase in the size of the focus area.

7. A graphics apparatus comprising:
a cache memory; and
logic communicatively coupled to the cache memory, the logic implemented at least partly in one or more of configurable hardware logic or fixed-functionality hardware logic, the logic to:
associate a first image portion with a focus area of an image based on eye-tracking information;
cause the first image portion to be rendered at a first rate;
cause a second image portion to be rendered at a second rate, wherein the second image portion is a region outside of the first image portion, and wherein the second rate is different from the first rate;
associate a third image portion with a relocation of the focus area of the image based on a change in the eye-tracking information; and
cause an adjustment to a size of the focus area, wherein the size of the focus area is to be adjusted based on at least one of a workload amount for the graphics apparatus or scene content.

8. The graphics apparatus of claim 7 , wherein before adjustment the focus area is a first shape, and after adjustment the focus area is a second shape, and wherein the first shape is one of a circular shape or an elliptical shape.

9. The graphics apparatus of claim 8 , wherein the second shape is an elliptical shape.

10. The graphics apparatus of claim 7 , wherein the first rate is higher than the second rate.

11. The graphics apparatus of claim 7 , wherein the logic is to cause the third image portion to be rendered at the first rate.

12. The graphics apparatus of claim 7 , wherein the adjustment to the size of the focus area results in an increase in the size of the focus area.

13. A method comprising:
associating a first image portion with a focus area of an image based on eye-tracking information;
rendering the first image portion at a first rate;
rendering a second image portion at a second rate, wherein the second image portion is a region outside of the first image portion, and wherein the second rate is different from the first rate;
associating a third image portion with a relocation of the focus area of the image based on a change in the eye-tracking information; and
adjusting a size of the focus area, wherein the size of the focus area is adjusted based on at least one of a workload amount for the graphics apparatus or scene content.

14. The method of claim 13 , wherein before adjusting the size of the focus area, the focus area is a first shape, and after adjusting the size of the focus area, the focus area is a second shape, and wherein the first shape is one of a circular shape or an elliptical shape.

15. The method of claim 14 , wherein the second shape is an elliptical shape.

16. The method of claim 13 , wherein the first rate is higher than the second rate.

17. The method of claim 13 , further comprising rendering the third image portion at the first rate.

18. The method of claim 13 , wherein adjusting the size of the focus area results in an increase in the size of the focus area.

19. A graphics apparatus comprising:
means for associating a first image portion with a focus area of an image based on eye-tracking information;
means for rendering the first image portion at a first rate;
means for rendering a second image portion at a second rate, wherein the second image portion is a region outside of the first image portion, and wherein the second rate is different from the first rate;
means for associating a third image portion with a relocation of the focus area of the image based on a change in the eye-tracking information; and
means for adjusting a size of the focus area, wherein the size of the focus area is adjusted based on at least one of a workload amount for the graphics apparatus or scene content.

20. The graphics apparatus of claim 19 , wherein before adjusting the size of the focus area, the focus area is a first shape, and after adjusting the size of the focus area, the focus area is a second shape, wherein the first shape is one of a circular shape or an elliptical shape, and wherein the second shape is an elliptical shape.

21. The graphics apparatus of claim 19 , wherein the first rate is higher than the second rate.

22. The graphics apparatus of claim 19 , further comprising means for rendering the third image portion at the first rate.

23. The graphics apparatus of claim 19 , wherein adjusting the size of the focus area results in an increase in the size of the focus area.
