Abstract

System and method for informing a user of functions or characters associated with keys on a mobile communications device includes a keyboard operable to input dual-tone multi-frequency (DTMF) codes and a display screen operable to display information. The display screen is also operable to display a virtual representation of at least a portion of the keyboard. The virtual representation includes help information on one or more virtually represented keys of the keyboard. This help information informs a user of an associated telephone function or character of one or more keys that are virtually represented on the display.

Claims

1. A communication device, comprising:

a display screen;

a keyboard having keys, each key having associated indicia corresponding to at least one of alphabetic characters, numbers, and functions, wherein the keys are operable to input corresponding Dual-Tone Multi-Frequency (DTMF) codes corresponding to the associated characters, numbers, or functions; and

a processor communicatively coupled with said keyboard and said display screen, said processor being configured to;

receive an input, via said keyboard, of one or more alphabetic characters of a phone number; and

cause the display of the inputted alphabetic characters on said display screen.

2. The communication device of claim 1 wherein the alphabetic characters are arranged in a non-ITU Standard E.161 phone keypad layout.

3. The communication device of claim 2 wherein the keyboard is a QWERTY layout or reduced QWERTY layout.

4. The communication device of claim 2 wherein the keyboard is a AZERTY, DVORAK, or QWERTZ layout, or a reduced version of any one of said layouts.

5. The communication device of claim 1 wherein the processor is configured to cause, on the display screen, the display of:

the phone number having alphabetic characters and numbers; and

a DTMF phone number having numbers corresponding to the alphabetic characters.

6. The communication device of claim 5 wherein said DTMF phone number is displayed below the phone number.

7. The communication device of claim 1 wherein an additional key is pressed in order to enter the alphabetic character.

8. The communication device of claim 1 wherein an ALT key is pressed in order to enter the alphabetic character.

9. The communication device of claim 1 wherein an additional key is pressed in combination with the alphabetic character in order to enter the alphabetic character.

10. The communication device of claim 1 wherein an ALT key is pressed in combination with the alphabetic character in order to enter the alphabetic character.

11. The communication device of claim 1 wherein a multi-tap technique is used to enter the alphabetic character.

12. A non-transitory medium configured to store instructions for execution by a processor of a communication device, the non-transitory medium includes instructions to:

receive an input, via a keyboard, of one or more alphabetic characters of a phone number, with each key of the keyboard having associated indicia corresponding to at least one of alphabetic characters, numbers, and functions, wherein the keys are operable to input corresponding DTMF codes corresponding to the associated characters, numbers or functions; and

cause display of the inputted alphabetic characters on a display screen of the communication device.

13. The non-transitory medium of claim 12 wherein the non-transitory medium includes instructions to cause, on the display screen, the display of:

the phone number having alphabetic characters and numbers; and

a DTMF phone number corresponding to the alphabetic characters.

14. The non-transitory medium of claim 13 wherein said DTMF phone number is displayed below the phone number.

15. The non-transitory medium of claim 12 wherein the alphabetic characters are arranged in a non-ITU Standard E.161 phone keypad layout.

16. The non-transitory medium of claim 15 wherein the keyboard is a QWERTY layout or reduced QWERTY layout.

17. The non-transitory medium of claim 15 wherein the keyboard is a AZERTY, DVORAK, or QWERTZ layout, or a reduced version of any one of said layouts.

18. The non-transitory medium of claim 12 wherein the received input further includes an additional key being pressed in order to enter the alphabetic character.

19. The non-transitory medium of claim 18 wherein the additional key is an ALT key in order to enter the alphabetic character.

20. The non-transitory medium of claim 18 wherein the ALT key is pressed in combination with the alphabetic character in order to enter the alphabetic character.
