Abstract

Systems, apparatuses, and methods may provide for technology to dynamically control a display in response to ocular characteristic measurements of at least one eye of a user.

First claim

What is claimed is:

1. An apparatus, comprising:
a graphics processor to dynamically adjust, in response to a measurement of at least one ocular characteristic of an eye of a user that includes a vertical palpebrae position relative to a pupil of the eye of the user, a rendering rate of an image for display between a full rendering and a partial rendering.

2. The apparatus of claim 1 , wherein the at least one ocular characteristic comprises a pupil dilation.

3. The apparatus of claim 2 , wherein the graphics processor is to dynamically adjust, in response to the measured pupil dilation, a brightness level of a display device to display the image.

4. The apparatus of claim 1 , wherein the logic is to dynamically render the image in a manner that corresponds to the measured vertical palpebrae position.

5. The apparatus of claim 1 , wherein the at least one ocular characteristic comprises at least one electrical impulse emitted by an extraocular muscle of the eye of the user.

6. The apparatus of claim 5 , wherein the graphics processor is to stop rendering of the image based on a prediction, in response to the measured at least one electrical impulse, of when the pupil is to be unexposed.

7. The apparatus of claim 6 , wherein the graphics processor is to resume rendering of the image based on a prediction, in response to the measured at least one electrical impulse, of when the pupil is to be exposed.

8. A method of processing an image for display, comprising:
dynamically adjusting, via a graphics processor in response to a measurement of at least one ocular characteristic of an eye of a user that includes a vertical palpebrae position relative to a pupil of the eye of the user, a rendering rate of the image between a full rendering and a partial rendering.

9. The method of claim 8 , wherein the at least one ocular characteristic comprises a pupil dilation.

10. The method of claim 9 , further comprising dynamically adjusting, via the graphics processor in response to the measured pupil dilation, a brightness level of a display device to display the image.

11. The method of claim 8 , further comprising dynamically rendering the image, via the graphics processor, in a manner that corresponds to the measured vertical palpebrae position.

12. The method of claim 8 , wherein the at least one ocular characteristic comprises at least one electrical impulse emitted by an extraocular muscle of the eye of the user.

13. The method of claim 12 , further comprising stopping the rendering of the image, via the graphics processor in response to a prediction based upon the measured at least one electrical impulse, of when a pupil is to be unexposed.

14. The method of claim 13 , further comprising resuming the rendering of the image, via the graphics processor in response to a prediction based upon the measured at least one electrical impulse, of when the pupil is to be exposed.

15. At least one computer readable medium, comprising a set of instructions, which when executed by a graphics processor of a computing device, cause the computing device to:
dynamically adjust, in response to a measurement of at least one ocular characteristic of an eye of a user that includes a vertical palpebrae position relative to a pupil of the eye of the user, a rendering rate of an image for display between a full rendering and a partial rendering.

16. The least one computer readable medium of claim 15 , wherein the at least one ocular characteristic comprises a pupil dilation.

17. The least one computer readable medium of claim 16 , wherein the computing device is caused to dynamically adjust, in response to the measured pupil dilation, a brightness level of a display device to display the image.

18. The least one computer readable medium of claim 15 , wherein the computing device is caused to dynamically render the image in a manner that corresponds to the measured vertical palpebrae position.

19. The least one computer readable medium of claim 15 , wherein the at least one ocular characteristic comprises at least one electrical impulse emitted by an extraocular muscle of the eye of the user.

20. The least one computer readable medium of claim 19 , wherein the computing device is caused to stop the rendering of the image, in response to a prediction based upon the measured at least one electrical impulse, of when the pupil is to be unexposed.

21. The least one computer readable medium of claim 20 , wherein the computing device is caused to resume the rendering of the image, in response to a prediction based upon the measured at least one electrical impulse, of when the pupil is to be exposed.
