Abstract

A touchscreen system for adapting a user interface broadly comprises a controller and a display screen, the display screen comprising a touchscreen. The display screen is operable to present the user interface. The controller may be configured to detect a defect in an area of the touchscreen, determine a location on the display screen related to the defect, and adapting the user interface on the display screen to compensate for the defect.

Claims

1. A method of adapting a user interface for a touchscreen system associated with a display screen, the method comprising the steps of:

a) detecting, using a processing element, a defect in an area of the touchscreen system;

b) determining, using the processing element, a location on the display screen related to the defect, the display screen presenting the user interface including one or more functional components selectable with a touch input over the viewable area of the display screen;

c) scaling, using the processing element, at least a portion of the user interface to be presented in a smaller area on the display screen;

d) adapting, using the processing element, the user interface on the display screen to compensate for the defect, wherein the user interface is adapted by presenting the one or more selectable functional components of the user interface on the display screen in areas other than in the location of the defect; and

e) identifying, using the processing element, a touch input in an area of the touchscreen system associated with a selectable functional component of the adapted user interface as a selection of the functional component.

2. The method of claim 1, wherein the user interface is adapted by decreasing the size of one or more selectable functional components presented on the display screen.

3. The method of claim 1, further comprising presenting an indicator on the display screen that the touchscreen system is inoperable in the area of the defect.

4. The method of claim 1, further comprising restoring the user interface to a default configuration once the defect is corrected.

5. The method of claim 1, wherein the scaling is at least partially based on stored user interface configuration information.

6. The method of claim 1, further comprising disabling a portion of the user interface prior to step d.

7. The method of claim 1, further comprising changing a location of where a portion of the user interface is to be presented prior to step d.

8. The method of claim 1, wherein step a) further comprises the steps of:

transmitting, using the processing element, a plurality of beams from a plurality of transmitters to a plurality of receivers,

generating, using the processing element, a receive signal from one or more of the receivers that detects at least one of the beams, and

analyzing, using the processing element, a status of the receive signals to detect the defect.

9. An adaptive touchscreen system comprising:

a display screen for presenting a user interface including one or more functional components selectable with a touch input over the viewable area of the display screen, the display screen comprising a touchscreen; and

a controller configured to

detect a defect in an area of the touchscreen,

determine a location on the display screen related to the defect,

scale at least a portion of the user interface to be presented in a smaller area on the display screen;

adapt the user interface to present the one or more selectable functional components of the user interface on the display screen in areas other than in the location of the defect; and

identify a touch input in an area of the touchscreen system associated with a selectable functional component of the adapted user interface as a selection of the functional component.

10. The system of claim 9, wherein the controller is further configured to cause an indicator to be presented on the display screen that the touchscreen system is inoperable in the area of the defect.

11. The system of claim 9, wherein the controller is further configured to restore the user interface to a default configuration once the defect is corrected.

12. The system of claim 9, wherein the scaling is at least partially based on stored user interface configuration information.

13. The system of claim 9, wherein the controller is further configured to disable a portion of the user interface.

14. The system of claim 9, wherein the controller is further configured to change a location of where a portion of the user interface is to be presented.

15. The system of claim 9, further comprising:

a plurality of transmitters for transmitting beams across the display screen, and

a plurality of receivers for detecting the beams from the transmitters and generating receive signals,

wherein the controller is in communication with the transmitters and the receivers and configured to analyze a status of the receive signals to detect the defect.

16. An adaptive touchscreen system comprising:

a display screen for presenting a user interface including one or more functional components selectable with a touch input over the viewable area of the display screen, the display screen comprising a touchscreen;

a plurality of transmitters for transmitting beams across the display screen;

a plurality of receivers for detecting the beams from the transmitters and generating receive signals; and

a controller configured to

analyze a status of the receive signals,

detect a defect in an area of the touchscreen,

determine a location on the display screen related to the defect,

scale at least a portion of the user interface to be presented in a smaller area on the display screen,

adapt the user interface to present the one or more selectable functional components of the user interface on the display screen in areas other than in the location of the defect; and

identify a touch input in an area of the touchscreen system associated with a selectable functional component of the adapted user interface as a selection of the functional component.

17. The system of claim 16, wherein the controller is further configured to present an indicator on the display screen that the touchscreen is inoperable in the area of the defect.

18. The system of claim 16, wherein the controller is further configured to restore the user interface to a default configuration once the defect is corrected.

19. The system of claim 16, wherein the scaling is at least partially based on stored user interface configuration information.

20. The system of claim 16, wherein the controller is further configured to disable a portion of the user interface.

21. The system of claim 16, wherein the controller is further configured to change an area of the display screen in which the user interface is to be presented.
