Abstract

The present invention includes a device, method, and user interface for providing optimized entry of alphanumeric text. In one form, a method for providing selectable characters within a user interface includes determining an operating mode of a communication device and receiving an input associated with a selected input key. The method determines a group of characters associated with the selected key based on the operating mode and displays the group of characters within the user interface. The user interface may display a first character of the group of characters within a first portion of the user interface and the group of characters proximal to the first character within a second portion of the user interface.

Claims

1. An interface, comprising:

a first display portion configured to display a plurality of soft keys;

a second display portion configured to;

display a group of characters associated with a first key selection in response to the first key being selected; and

highlight a first character in the group of characters; and

a processor operable to;

determine an amount of time that has elapsed since the first key selection;

if an amount of time is greater than a time-out period, automatically select the highlighted character; and

calculate a new time-out period based on a time interval between the first key selection and a second key selection.

2. The interface of claim 1, wherein the second key selection is the same as the first key selection.

3. The interface of claim 2, further comprising a third display portion configured to highlight a second character in the group of characters upon receiving the second key selection.

4. The interface of claim 2, wherein the processor is further operable to calculate an average time-out period for a user.

5. The interface of claim 1, wherein the processor is further operable to:

associate the new time-out period with a user; and

store the association of the new time-out period with the user.

6. The interface of claim 1, wherein the first display portion is further configured to display a cursor alongside the highlighted first character.

7. A method, comprising:

receiving a first key selection;

determining a group of characters associated with the first key selection;

displaying the group of characters associated with the first key selection within a first portion of a user interface;

highlighting a first character in the group of characters;

determining an amount of time that has elapsed since the first key selection; and

if the amount of time is greater than a time-out period, automatically selecting the highlighted character;

receiving a second key selection;

determining a time interval between the first key selection and the second key selection; and

calculating a new time-out period according to the time interval.

8. The method of claim 7, wherein the second key selection is the same as the first key selection.

9. The method of claim 8, further comprising highlighting a second character in the group of characters upon receiving the second key selection.

10. The method of claim 8, wherein calculating the new time-out period comprises calculating an average time-out period for a user.

11. The method of claim 7, further comprising:

associating the new time-out period with a user; and

storing the association of the new time-out period with the user.

12. The method of claim 7, further comprising displaying a cursor alongside the highlighted first character.

13. A non-transitory computer readable medium comprising encoded logic configured, when executed by a processor, to cause a user interface to:

receive a first key selection;

determine a group of characters associated with the first key selection;

display the group of characters associated with the first key selection within a first portion of a user interface;

highlight a first character in the group of characters;

determine an amount of time that has elapsed since the first key selection; and

if the amount of time is greater than a time-out period, automatically select the highlighted character;

receive a second key selection;

determine a time interval between the first key selection and the second key selection; and

calculate a new time-out period according to the time interval.

14. The computer readable medium of claim 13, wherein the second key selection is the same as the first key selection.

15. The computer readable medium of claim 14, wherein the logic is further configured to highlight a second character in the group of characters upon receiving the second key selection.

16. The computer readable medium of claim 14, wherein the calculation of the new time-out period comprises calculating an average time-out period for a user.

17. The computer readable medium of claim 13, wherein the logic is further configured to:

associate the new time-out period with a user; and

store the association of the new time-out period with the user.

18. The computer readable medium of claim 13, wherein the logic is further configured to display a cursor alongside the highlighted first character.
