System and method for context aware usability management of human machine interfaces

1. A non-transitory computer-readable medium including code for performing a method, the method comprising:

providing a first keypad image to a display of a mobile device;

determining, by a sensor of the mobile device, that a first motion level of the mobile device represents a still context for the mobile device;

receiving, by the mobile device, a first touch pad input for a first character associated with the first keypad image in response to determining that the first motion level represents the still context;

determining, by the sensor, that a second motion level of the mobile device represents a first moving context for the mobile device;

receiving, by a touch pad adjuster of the mobile device, a second touch pad input, wherein the second touch pad input comprises a sequence of selections of a plurality of characters associated with the keypad image in response to determining that the second motion level represents the first moving context;

averaging the sequence of selections; and

providing, from the touch pad adjuster, a second character input to the mobile device in response to the averaging.

2. The computer-readable medium of claim 1 , wherein the second character input is determined to indicate the second character based upon the sequence of selections including a larger number of touches to the second character than to any other character.

3. The computer-readable medium of claim 1 , wherein the second character input is determined to indicate the second character based upon the sequence of selections having a longest average touch duration on the second character.

4. The computer readable medium of claim 1 , wherein the characters include overlapping touch pad input areas.

5. The computer readable medium of claim 4 , wherein the overlapping touch pad input areas provide for enlarged touch pad input areas for the characters.

6. The computer-readable medium of claim 1 , the method further comprising:

displaying the characters as enlarged touch pad input areas.

7. A mobile device comprising:

a display operable to display a first keypad image;

a sensor operable to:

determine that a first motion level of the mobile device represents a still context for the mobile device; and

determine that a second motion level of the mobile device represents a moving context for the mobile device; and

a touch pad adjuster;

wherein the mobile device is operable to receive a first touch pad input for a first character associated with the first keypad image in response to determining that the first motion level represents the still context; and

wherein the touch pad adjuster is operable to:

receive a second touch pad input, wherein the second touch pad input comprises a sequence of selections of a plurality of characters associated with the keypad image in response to determining that the second motion level represents the first moving context;

average the sequence of selections; and

provide a second character input in response to the averaging.

8. The mobile device of claim 7 , wherein the second character input is determined to indicate the second character based upon the sequence of selections including a larger number of touches to the second character than to any other character.

9. The mobile device of claim 7 , wherein the second character input is determined to indicate the second character based upon the sequence of selections having a longest average touch duration on the second character.

10. The mobile device of claim 7 , wherein the characters include overlapping touch pad input areas.

11. The mobile device of claim 10 , wherein the overlapping touch pad input areas provide for enlarged touch pad input areas for the characters.

12. The mobile device of claim 7 , wherein the characters are displayed as enlarged touch pad input areas.

13. A method comprising:

providing a first keypad image to a display of a mobile device;

determining, by a sensor of the mobile device, that a first motion level of the mobile device represents a still context for the mobile device;

receiving, by the mobile device, a first touch pad input for a first character associated with the first keypad image in response to determining that the first motion level represents the still context;

determining, by the sensor, that a second motion level of the mobile device represents a first moving context for the mobile device;

receiving, by a touch pad adjuster of the mobile device, a second touch pad input, wherein the second touch pad input comprises a sequence of selections of a plurality of characters associated with the keypad image in response to determining that the second motion level represents the first moving context;

averaging the sequence of selections; and

providing, from the touch pad adjuster, a second character input to the mobile device in response to the averaging.

14. The method of claim 13 , wherein the second character input is determined to indicate the second character based upon the sequence of selections including a larger number of touches to the second character than to any other character.

15. The method of claim 13 , wherein the second character input is determined to indicate the second character based upon the sequence of selections having a longest average touch duration on the second character.

16. The method of claim 13 , wherein the characters include overlapping touch pad input areas.

17. The method of claim 16 , wherein the overlapping touch pad input areas provide for enlarged touch pad input areas for the characters.

18. The method of claim 13 , the method further comprising:

displaying the characters as enlarged touch pad input areas.
