Abstract

A portable electronic device comprising a user input device, a device for presenting information to a user, and a processor for receiving inputs from the user input device and altering the operating state of the portable electronic device accordingly, the processor being operable to present a menu of items to a user, from which an item may be selected by a user by means of the user input device, wherein the menu of items includes both operands and text entry characters.

Claims

1. A portable electronic device, comprising:

a user input device comprising a plurality of directional inputs for enabling a user to input alphanumeric characters into the electronic device, where each of the directional inputs is associated with a different group of alphanumeric characters, and each character in the group is associated with a different mode of actuation of the directional input;

a display for presenting information to a user indicative of the group of alphanumeric characters associated with each of the directional inputs;

a processor for controlling the electronic device operable to detect actuation of the directional inputs and determine the mode of actuation of the directional input and select the character associated with the mode of actuation of the actuated directional input.

2. A portable electronic device as claimed in claim 1 wherein the currently selected character is highlighted on the display.

3. A portable electronic device as claimed in claim 1 wherein the processor is operable to detect an interrupt and, in response to the interrupt, enter the currently selected character into the electronic device.

4. A portable electronic device as claimed in claim 3 wherein the interrupt comprises a depression of the user input device.

5. A portable electronic device as claimed in claim 3 wherein the interrupt comprises a detection that no further input has occurred within a predetermined time.

6. A portable electronic device as claimed in claim 3 wherein once a character has been entered into the electronic device the character is displayed on the display.

7. A portable electronic device as claimed in claim 1 wherein the mode of actuation comprises the number of actuations of the directional input.

8. A portable electronic device as claimed in claim 1 wherein the user input device comprises a joystick.

9. A portable electronic device as claimed in claim 8 wherein the joystick includes four directional inputs.

10. A method of inputting alphanumeric characters into an electronic device comprising a plurality of directional user input devices, the method comprising;

presenting groups of alphanumeric characters to a user where each of the groups of alphanumeric characters are associated with a different directional input and each character in the group is associated with a different mode of actuation of the directional input;

detecting actuation of one of the directional user inputs;

determining the mode of actuation of the directional user input;

selecting the alphanumeric character associated with the mode of actuation of the directional input.

11. A method as claimed in claim 10 wherein the currently selected character is highlighted on the display.

12. A method as claimed in claim 10 further comprising detecting an interrupt and, in response to the interrupt, entering the currently selected character into the electronic device.

13. A method as claimed in claim 12 wherein the interrupt comprises a depression of the user input device.

14. A method as claimed in claim 12 wherein the interrupt comprises a detection that no further input has occurred within a predetermined time.

15. A method as claimed in claim 12 wherein once a character has been entered into the electronic device the character is displayed on the display.

16. A method as claimed in claim 10 wherein the mode of actuation comprises the number of actuations of the directional input.

17. A computer program comprising program instructions for controlling an electronic device, the electronic device having a display and a plurality of directional user input devices, which, when loaded into a processor, provides:

means for presenting groups of alphanumeric characters to a user where each of the groups of alphanumeric characters are associated with a different directional input and each character in the group is associated with a different mode of actuation of the directional input;

means for detecting actuation of one of the directional user inputs;

means for determining the mode of actuation of the directional user input; and

means for selecting the alphanumeric character associated with the mode of actuation of the directional input

18. A graphical user interface configured to:

display groups of alphanumeric characters to a user where each of the groups of alphanumeric characters are associated with a different directional input of a user input device and each character in the group is associated with a different mode of actuation of the directional input; and

enable the selection of a characters for entering into the electronic device.
