Abstract

Disclosed are systems and methods for identifying user input. In one embodiment, a system and method pertain to detecting application of a force to a user interface using input sensors that are laterally spaced from the point at which the force is applied, and calculating the location at which the force is applied using information collected by the input sensors.

Claims

1. A method for identifying a user input, comprising:

detecting application of a force to a user interface using input sensors that are laterally spaced from a point at which the force is applied; and

calculating the location at which the force is applied using information collected by the input sensors.

2. The method of claim 1, wherein detecting application of a force comprises detecting application of a force using input sensors positioned at a perimeter of the user interface.

3. The method of claim 1, wherein calculating the location at which the force is applied comprises comparing the information collected by each of the input sensors.

4. The method of claim 1, wherein calculating the location at which the force is applied comprises calculating the location from forces measured by the input sensors.

5. The method of claim 1, wherein calculating the location at which the force is applied comprises calculating the location from deflections measured by the input sensors.

6. The method of claim 1, wherein calculating the location at which the force is applied comprises calculating the location from vibrations measured by the input sensors.

7. The method of claim 1, wherein calculating the location at which the force is applied comprises calculating the location from the times at which vibrations are detected by the input sensors.

8. The method of claim 1, further comprising interpreting an intended user input from the calculated location.

9. The method of claim 8, wherein interpreting an intended user input comprises correlating the calculated location using a user interface map.

10. A system for identifying a user input, comprising:

a user interface to which a force may be applied to register a user input;

input sensors that are laterally spaced from areas of the user interface to which the force may be applied; and

an input analysis manager that is configured to calculate the location at which a force is applied to the user interface using information collected by the input sensors.

11. The system of claim 10, wherein the user interface comprises a display.

12. The system of claim 11, wherein the input sensors are positioned at a perimeter of the display.

13. The system of claim 10, wherein the user interface comprises a control panel including at least one mock button.

14. The system of claim 13, wherein the input sensors are positioned at a perimeter of the control panel.

15. The system of claim 10, wherein the input sensors comprise a force sensor that measures force transmitted through the user interface.

16. The system of claim 10, wherein the input sensors comprise a displacement sensor that measures displacement of a discrete portion of the user interface.

17. The system of claim 10, wherein the input sensors comprise a vibration sensor that measures vibrations that propagate through the user interface.

18. The system of claim 10, wherein the input sensors comprise a vibration sensor that detects arrival of vibrations that propagate through the user interface and wherein the input analysis manager is configured to identify the time at which the vibrations arrived at each vibration sensor.

19. The system of claim 10, wherein the input analysis manager is configured to calculate the distances between the input sensors and the location at which the force was applied by comparing the information collected by the sensors.

20. The system of claim 10, wherein the input analysis manager is configured to interpret an intended user input from the calculated location at which the force was applied.

21. A system for identifying a user input, comprising:

means for detecting a force applied to a user interface, the means for detecting being laterally from the location at which the force was applied; and

means for calculating the location of the applied force.

22. The system of claim 21, wherein the means for detecting comprise no greater than four input sensors.

23. The system of claim 21, wherein the input sensors are positioned around a perimeter of the user interface.

24. The system of claim 21, wherein the means for calculating comprise means for calculating the distances between input sensors and the location at which the force was applied.

25. A user interface, comprising:

a display having an outer perimeter; and

input sensors provided only around the outer perimeter of the display, the input sensors being configured to detect application of force to the display.

26. The user interface of claim 25, wherein the interface only comprises three input sensors.

27. A user interface, comprising:

a control panel including a plurality of mock buttons; and

input sensors laterally spaced from the mock buttons that are configured to detect application of force to the mock buttons.

28. The user interface of claim 27, wherein the mock buttons comprise indicia that identify an associated function and an indication as to the boundaries of the mock buttons, the interface being absent of dedicated switches for the mock buttons.
