Abstract

A method includes determining by a sensor of a mobile device that a first ambient sound level represents a quiet context for the mobile device, providing a audio signal to a speaker of the mobile device in response to determining that the first ambient sound level represents a quiet context, determining, by the sensor, that a second ambient sound level represents a first noisy context for the mobile device, wherein the second ambient sound level is louder than the first ambient sound level, modifying the audio signal into a beam forming audio signal in response to determining that the second ambient sound level represents the first noisy context, and providing the beam forming audio signal to the speaker.

Claims

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.
