Abstract

Systems, apparatus, articles, and methods are described including operations for eye tracking based selective backlighting of a display.

First claim

What is claimed:

1. A computer-implemented method for selectively backlighting a display of a computer, comprising:
receiving visual data, wherein the visual data includes video of one or more users;
performing eye tracking for at least one of the one or more users based at least in part on the received visual data;
determining a region of interest associated with a portion of the display of the computer system based at least in part on the performed eye tracking; and
selectively backlighting the portion of the display associated with the determined region of interest and dimming a secondary portion of the display that is not associated with the determined region of interest;
determining whether or not an application has been selectively designated for operation with eye tracking; and
determining whether or not at least one of the one or more users is present based at least in part on the received visual data, wherein the determination of whether or not at least one of the one or more users is present occurs in response to the determination that the application has been selectively designated for operation with eye tracking.

2. The method of claim 1 ,
wherein the selective backlighting comprises selectively backlighting an area based at least in part on associating the region of interest with a discrete display element, wherein the discrete display element comprises a paragraph of text and/or a default number of text lines.

3. The method of claim 1 , further comprising:
determining whether or not at least one of the one or more users is present based at least in part on the received visual data, and
wherein the performance of eye tracking occurs in response to the determination that at least one of the one or more users is present, for at least one of the one or more users.

4. The method of claim 1 , further comprising:
determining whether or not an application has been designated for operation with eye tracking; and
determining whether or not at least one of the one or more users is present based at least in part on the received visual data, wherein the determination of whether or not at least one of the one or more users is present occurs in response to the determination that the application has been designated for operation with eye tracking,
wherein the performance of eye tracking occurs in response to the determination that at least one of the one or more users is present, for at least one of the one or more users.

5. The method of claim 1 , wherein the selective backlighting comprises selectively backlighting an area based at least in part on a default area size.

6. The method of claim 1 , wherein the selective backlighting comprises selectively backlighting an area based at least in part on associating the region of interest with a discrete display element, wherein the discrete display element comprises a text box, a paragraph of text, a default number of text lines, a picture, and/or a menu.

7. The method of claim 1 , wherein the selective backlighting comprises turning off a previously lit portion of backlighting associated with the secondary portion of the display.

8. The method of claim 1 , wherein the selective backlighting comprises turning on a previously dimmed portion of backlighting associated with the portion of the display associated with the determined region of interest.

9. The method of claim 1 , further comprising:
determining whether or not at least one of the one or more users is present based at least in part on the received visual data, and
completely dimming the display in response to the received visual data based at least in part on a determination that none of the one or more users is present.

10. The method of claim 1 , further comprising:
completely dimming the display in response to the received visual data based at least in part on a determination that none of the one or more users eyes are directed at the display in response to the performed eye tracking.

11. The method of claim 1 , further comprising:
completely dimming the display in response to the received visual data based at least in part on a determination that none of the one or more users is present and/or on a determination that none of the one or more users eyes are directed at the display in response to the performed eye tracking, and
wherein the performance of eye tracking occurs in response to the determination that at least one of the one or more users is present, for at least one of the one or more users,
wherein the selective backlighting comprises selectively backlighting an area based at least in part on a default area size and/or selectively backlighting an area based at least in part on associating the region of interest with a discrete display element, wherein the discrete display element comprises a text box, a paragraph of text, a default number of text lines, a picture, and/or a menu,
wherein the selective backlighting comprises turning off a previously lit portion of backlighting associated with the secondary portion of the display and/or turning on a previously dimmed portion of backlighting associated with the portion of the display associated with the determined region of interest.

12. A system for selectively backlighting a computer, comprising:
a display;
an imaging device configured to capture visual data;
one or more processors communicatively coupled to the display and to the imaging device;
one or more memory stores communicatively coupled to the one or more processors;
a visual data logic module communicatively coupled to the one or more processors and the one or more memory stores and configured to receive visual data, wherein the visual data includes video of one or more users;
an eye tracking logic module communicatively coupled to the one or more processors and the one or more memory stores and configured to perform eye tracking for at least one of the one or more users based at least in part on the received visual data;
a region of interest logic module communicatively coupled to the one or more processors and the one or more memory stores and configured to determine a region of interest associated with a portion of the display based at least in part on the performed eye tracking;
a selective backlighting logic module communicatively coupled to the one or more processors and the one or more memory stores and configured to selectively backlight the portion of the display associated with the determined region of interest and dim a secondary portion of the display that is not associated with the determined region of interest; and
a user presence logic module communicatively coupled to the one or more processors and the one or more memory stores and configured to determine whether or not at least one of the one or more users is present based at least in part on the received visual data, wherein the determination of whether or not at least one of the one or more users is present occurs in response to a determination that the application has been selectively designated for operation with eye tracking.

13. The system of claim 12 ,
wherein the selective backlighting comprises selectively backlighting an area based at least in part on associating the region of interest with a discrete display element, wherein the discrete display element comprises a paragraph of text and/or a default number of text lines.

14. The system of claim 12 , further comprising:
a user presence logic module communicatively coupled to the one or more processors and the one or more memory stores and configured to determine whether or not at least one of the one or more users is present based at least in part on
