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.

First claim

That which is claimed is:

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.
