Abstract

A method of correcting an error in user input is described. The method includes monitoring for an occurrence of a shake in a user equipment, detecting a shake, comparing the detected shake with a threshold value, evaluating characters within a pre-determined distance of a character entered by the user during the shake, selecting a replacement character from the evaluated characters and replacing the entered character with the replacement character.

Claims

1. A user equipment comprising:

a transceiver for communicating data;

a memory for storing data;

a sensor for detecting movement; and

a processor for;

evaluating the detected movement;

evaluating characters within a pre-determined distance of a character entered by a user during the movement;

selecting a replacement character from the evaluated characters; and

replacing the entered character with the replacement character.

2. The user equipment of claim 1, wherein the sensor is an accelerometer.

3. The user equipment of claim 2, wherein the accelerometer detects a shake associated with the user equipment.

4. The user equipment of claim 1, wherein the memory further comprises:

a database of words.

5. The user equipment of claim 1, further comprising a graphical user interface with a virtual onscreen keyboard.

6. A method of correcting an error in user input comprising:

monitoring for an occurrence of a shake in a user equipment;

detecting a shake;

comparing the detected shake with a threshold value;

evaluating characters within a pre-determined distance of a character entered by the user during the shake;

selecting a replacement character from the evaluated characters; and

replacing the entered character with the replacement character.

7. The method of claim 6, wherein the characters are evaluated if the detected shake is greater than the threshold value.

8. The method of claim 6, further comprising:

measuring a magnitude of the shake;

determining a distance from the character entered during the shake based on the magnitude of the shake.

9. The method of claim 8, wherein the distance is a linear distance on a virtual keyboard of the user equipment.

10. The method of claim 6 further comprising:

providing a notification to the user,

11. The method of claim 10, wherein the notification is an aural notification.

12. The method of claim 10, wherein the notification is a visual notification.

13. The method of claim 6, wherein the shake is monitored by a sensor.

14. The method of claim 6, wherein the sensor is an accelerometer.

15. A method for correcting an error in user input comprising:

monitoring for an occurrence of a shake in a user equipment;

evaluating the shake; and

determining a user entry based on the evaluation.

16. A computer program comprising computer readable program modules which when run on a user equipment causes the user equipment to:

monitor for an occurrence of a shake in a user equipment;

detect a shake;

compare the detected shake with a threshold value;

evaluate characters within a pre-determined distance of a character entered by the user during the shake;

select a replacement character from the evaluated characters; and

replace the entered character with the replacement character.
