Abstract

Adaptive text input modes for a mobile electronic device permit efficient entry of hybrid alpha-numeric text records, such as street addresses and calendar dates, using a keypad. Adaptive text input modes automatically toggle between different text input modes in a manner that conforms to expected formats for text records. The number of keypad inputs is thereby reduced without the need for a user of the mobile electronic device to manually toggle between text input modes when entering text records on the keypad. The adaptive text input modes may be selected based on location information.

Claims

1. A method for generating a hybrid alpha-numeric text record on a mobile electronic device using a keypad, comprising:

selecting an adaptive text input mode for the text record based on location information; and

generating a plurality of characters of the text record in conformance with the adaptive text input mode in response to a respective plurality of inputs on the keypad.

2. The method of claim 1 wherein the adaptive text input mode comprises a numeric text input mode and a multi-tap text input mode.

3. The method of claim 1 wherein the plurality of inputs comprises one or more single tap inputs and one or more multi-tap inputs.

4. The method of claim 1 wherein the adaptive text input mode specifies a first text input mode, a second text input mode and a mode delimiter for the text record.

5. The method of claim 1 wherein the location information is acquired by the mobile electronic device from one of a network node and a global positioning system (GPS) satellite.

6. The method of claim 1 wherein the location information is acquired by the mobile electronic device from a user of the mobile electronic device.

7. The method of claim 1 wherein the location information comprises country information.

8. The method of claim 1 wherein the text record comprises street address information.

9. The method of claim 1, wherein the text record comprises calendar date information.

10. A method for generating a hybrid alpha-numeric text record on a mobile electronic device using a keypad, comprising:

selecting an adaptive text input mode specifying a first text input mode, a second text input mode and a mode delimiter applicable to the text record;

in response to one or more first inputs on the keypad, generating one or more first characters of the text record in conformance with the first text input mode;

in response to one or more second inputs on the keypad including the mode delimiter, switching between the first text input mode and the second text input mode; and

in response to one or more third inputs on the keypad, generating one or more second characters of the text record in conformance with the second text input mode.

11. The method of claim 10, wherein the adaptive text input mode is selected based on location information.

12. The method of claim 11 wherein the location information is acquired by the mobile electronic device from one of a network node and a GPS satellite.

13. The method of claim 11 wherein the location information is acquired by the mobile electronic device from a user of the mobile electronic device.

14. The method of claim 11 wherein the location information comprises country information.

15. The method of claim 10 wherein the text record comprises at least one of street address information and calendar date information.

16. A mobile electronic device, comprising:

a memory adapted to store an adaptive text input mode;

a keypad adapted to receive a plurality of inputs; and

a processor communicatively coupled with the memory and the keypad and adapted to select the adaptive text input mode and generate a respective plurality of characters of a text record in conformance with the adaptive text input mode in response to the plurality of inputs.

17. The method of claim 16 wherein the adaptive text input mode comprises a numeric text input mode and a multi-tap text input mode.

18. The method of claim 16 wherein the plurality of inputs comprises one or more single tap inputs and one or more multi-tap inputs.

19. The method of claim 16 wherein the adaptive text input mode specifies a first text input mode, a second text input mode and a mode delimiter for the text record.

20. The method of claim 16 wherein the adaptive text input mode is selected based on location information.
