Abstract

The virtual vision correction technique described herein pertains to a technique for determining a user'"'"'s vision characteristics and/or adjusting a display to a user'"'"'s vision characteristics. The virtual vision correction technique described herein provides vision correction for people with vision problems by making the video displayed adapt to the person'"'"'s vision correction needs. In one embodiment of the technique, the user can state their vision prescription needs and the video displayed is processed to appear “20/20” to that person. Alternatively, the video display, for example, video display glasses, can “auto-tune” a representative image (such as an eye chart) to determine the appropriate video processing for that person.

Claims

1. A system for automatically determining a user'"'"'s vision characteristics comprising:

a general purpose computing device;

a computer program comprising program modules executable by the general purpose computing device, wherein the computing device is directed by the program modules of the computer program to,

automatically determine settings for vision correction of a user by adjusting a digital image on a computer display.

2. The system of claim 1, further comprising:

a module for adjusting the digital image on the computer display to match the automatically determined setting for vision correction.

3. The system of claim 1, further comprising:

a module for obtaining the user'"'"'s feedback when viewing the digital image on the computer display to determine the settings for vision correction.

4. The system of claim 1, wherein the computer display comprises a display embodied in video display glasses.

5. The system of claim 1, wherein the computer display comprises a display on a wall.

6. The system of claim 1, wherein the user'"'"'s settings for vision correction are determined by using an eye chart displayed on the computer display and a keypad for entering characters of the eye chart displayed on the computer display read by the user.

7. The system of claim 1, wherein the user'"'"'s settings for vision correction are determined by using an eye chart displayed on the computer display and a touch screen on the computer display for indicating characters on the eye chart displayed on the display that the user can read.

8. The system of claim 1, wherein the user'"'"'s settings for vision correction are determined by using an eye chart displayed on the computer display and a microphone for indicating characters on the eye chart displayed on the computer display that the user can read.

9. The system of claim 1, wherein the user'"'"'s settings for vision correction are based on the user'"'"'s ability to determine colors and the settings for vision correction are determined by using a color eye chart displayed on the computer display and a means for indicating the colors the user can read.

10. A computer-implemented process for adapting video displayed in video display glasses to a user'"'"'s vision, comprising:

using a computing device for;

determining the user'"'"'s vision characteristics; and

changing the video displayed in the video display glasses to accommodate the determined user'"'"'s vision characteristics.

11. The computer-implemented process of claim 10, further comprising automatically tuning the video displayed based on user feedback on the changed video displayed to accommodate the determined user'"'"'s vision characteristics.

12. The computer-implemented process of claim 10, wherein changing the video displayed further comprises computing a transform to change the focus of the video on the display to conform to the user'"'"'s determined vision characteristics.

13. The computer-implemented process of claim 10, wherein changing the video displayed further comprises computing a transform to highlight edges in the video displayed on the display, guided by the user'"'"'s determined vision characteristics.

14. The computer-implemented process of claim 10, wherein changing the video displayed further comprises computing a transform to change the color palette of the video displayed on the display, guided by the user'"'"'s determined vision characteristics.

15. A computer-implemented process for adapting video displayed to a user'"'"'s vision, comprising:

using a computing device for;

automatically adjusting an image on a display to accommodate a user'"'"'s vision characteristics.

16. The computer-implemented process of claim 15, further comprising prompting the user for feedback while adjusting the image on the display.

17. The computer-implemented process of claim 16, further comprising automatically adjusting the image on the display based on the user'"'"'s feedback.

18. The computer-implemented process of claim 15, further comprising utilizing a graphics processor to aid in adjusting the image on the display.

19. The computer-implemented process of claim 18, further comprising utilizing special lenses to aid in adjusting the image on the display.

20. The computer-implemented process of claim 15, further comprising determining a user'"'"'s vision characteristics prior to adjusting the image on the display.
