Abstract

Systems and methods for compensating for visual distortion caused by surface features on a display are disclosed. For example, one disclosed system includes: a display including one or more surface features; a processor configured to: receive a display signal including graphical data; determine a location of the surface feature; transform the display signal based at least in part on the location of the surface feature; and cause the transformed display signal to be displayed.

Claims

1. A system, comprising:

a display comprising a touch-screen comprising a surface feature; and

a processor coupled to the touch-screen and the display, the processor configured to;

receive a display signal associated with an image;

receive a signal associated with the surface feature;

transform the display signal based at least in part on the surface feature; and

transmit the transformed display signal to the display.

2. The system of claim 1, wherein the touch-screen comprises a transparent surface.

3. The system of claim 1, further comprising a substrate associated with the surface feature, and wherein the processor is further configured to:

transmit a deformation signal associated with a deformation to the substrate,

the substrate configured to modify the surface feature based on the deformation signal.

4. The system of claim 3, further comprising:

an optical sensor configured to detect optical information and transmit a user signal;

wherein the processor is further configured to receive the user signal; and

wherein the deformation is associated with the user signal.

5. The system of claim 4, wherein the deformation is configured to magnify the user'"'"'s view of the display.

6. The system of claim 4, wherein the user signal comprises data associated with one or more of a viewing angle or eye movements.

7. A method comprising:

receiving a display signal associated with an image;

receiving a signal associated with a surface feature on a touch-screen;

transforming the display signal based at least in part on the surface feature; and

transmitting the transformed display signal to a display, wherein the display comprises the touch-screen.

8. The method of claim 7, wherein the touch-screen comprises a transparent surface.

9. The method of claim 7, further comprising:

transmitting a deformation signal associated with a deformation to a substrate associated with the surface feature, the substrate configured to modify the surface feature based on the deformation signal.

10. The method of claim 9, further comprising:

receiving a user signal from an optical sensor configured to detect information associated with a user and transmit a user signal; and

wherein the surface feature is associated with the user signal.

11. The method of claim 10, wherein the deformation is configured to magnify the user'"'"'s view of the display.

12. The method of claim 10, wherein the user signal comprises data associated with one or more of the user'"'"'s viewing angle or the user'"'"'s eye movements.

13. A non-transitory computer readable medium comprising program code, which, when executed by a processor, is configured to cause the processor to:

receive a display signal associated with an image;

receive a signal associated with a surface feature on a touch-screen;

transform the display signal based at least in part on the surface feature; and

transmit the transformed display signal to a display, wherein the display comprises the touch-screen.

14. The non-transitory computer readable medium of claim 13, wherein the touch-screen comprises a transparent surface.

15. The non-transitory computer readable medium of claim 13, further comprising:

transmitting a deformation signal associated with a deformation to a substrate associated with the surface feature, the substrate configured to modify the surface feature based on the deformation signal.

16. The non-transitory computer readable medium of claim 15, further comprising:

receiving a user signal from an optical sensor configured to detect information associated with a user and transmit a user signal; and

wherein the surface feature is associated with the user signal.

17. The non-transitory computer readable medium of claim 16, wherein the deformation is configured to magnify the user'"'"'s view of the display.

18. The non-transitory computer readable medium of claim 16, wherein the user signal comprises data associated with one or more of the user'"'"'s viewing angle or the user'"'"'s eye movements.
