Abstract

A customizable keyboard for a handheld electronic device is provided. The keys of the keyboard are rotatable, either individually or in groups, either under manual control of a user of the device or by means of one or more micro-motors or solenoids controlled by a microprocessor running software on the device. The keyboard may be integrated in the device or may be detachable therefrom.

Claims

1. A keyboard comprising:

a key guide; and

a plurality of keys, each retained laterally in said key guide and operable for providing input to a device when depressed by a switch-activation distance in a direction substantially perpendicular to a plane defined by said key guide;

wherein each key of said plurality of keys is rotatable about a respective axis of rotation substantially perpendicular to said plane.

2. The keyboard of claim 1, wherein said key guide and each key of said plurality of keys are co-operatively shaped for limiting rotation of that key to a predetermined range of orientations.

3. The keyboard of claim 1, wherein said key guide and each key of said plurality of keys are co-operatively shaped for impeding rotation of that key from a predetermined orientation.

4. The keyboard of claim 3, wherein rotation of each key of said plurality of keys from said predetermined orientation requires at least one of:

application of a predetermined torque to that key about its respective axis of rotation; and

depression of that key by a release distance, wherein said release distance is greater than said activation distance.

5. The keyboard of claim 4, wherein each key of said plurality of keys includes one of a respective projection and a respective depression;

and wherein said key guide includes, for that key, one of, respectively, a corresponding depression for receiving the respective projection when that key is in the predetermined orientation and a corresponding projection for reception by the respective depression when that key is in the predetermined orientation.

6. The keyboard of claim 1, wherein each key of said plurality of keys is shaped for receiving a complementary tool for applying torque to that key about its respective axis of rotation.

7. The keyboard of claim 6, wherein each key of said plurality of keys is shaped so that a periphery of an upper portion of that key is shaped for matingly receiving the tool about at least part of said periphery.

8. The keyboard of claim 6, wherein each key of said plurality of keys is shaped so that an upper portion of that key forms a depression for receiving the tool within said depression.

9. The keyboard of claim 1, further comprising an actuator located beneath said key guide and in communication with at least one key of said plurality of keys, wherein motion of said actuator causes rotation of each key of said at least one key.

10. The keyboard of claim 9, wherein said at least one key comprises at least two keys arranged in one of a row and a column.

11. The keyboard of claim 9, wherein said actuator is capable of lateral movement.

12. The keyboard of claim 11, wherein said actuator comprises an elongate member;

wherein each key of said at least one key includes one of a respective projection and a respective depression; and

wherein said elongate member includes, for that key, one of, respectively, a corresponding depression for receiving the respective projection and a corresponding projection for reception by the respective depression.

13. The keyboard of claim 12, wherein said elongate member comprises a rack, and wherein each key of said at least one key includes a pinion engaging said rack.

14. The keyboard of claim 9, wherein said actuator comprises a worm gear capable of rotation, and wherein each key of said at least one key includes a respective projection received by said worm gear.

15. The keyboard of claim 14, wherein said worm gear comprises two portions having oppositely inclined threads, whereby motion of said worm gear rotates two keys of said at least one key in opposite rotational directions.

16. The keyboard of claim 9, wherein said actuator is operable to simultaneously rotate two keys of said at least one key through angles of different, respective magnitudes.

17. The keyboard of claim 16, wherein said respective magnitudes increase in relation to respective distances of said two keys from a bilateral axis of the keyboard.

18. The keyboard of claim 9, wherein motion of said actuator is manually controllable.

19. The keyboard of claim 9, wherein said actuator includes an electro-mechanical impeller.

20. The keyboard of claim 19, wherein said impeller comprises one of a micro-motor and a solenoid.

21. The keyboard of claim 19, wherein said impeller is controllable by a microprocessor of the device executing computer-readable instructions.

22. The keyboard of claim 21, wherein control of said impeller by the microprocessor is based on at least one of a software application running on the device and a user input received at the device.

23. The keyboard of claim 1, wherein an upper portion of each key of said plurality of keys has a generally oblong shape.

24. The keyboard of claim 1, wherein the keyboard is detachable from the device;

and wherein each key of said plurality of keys, when depressed, depresses a respective key of an integrated keyboard of the device.

25. A handheld electronic device comprising:

a microprocessor;

a keyboard in electro-mechanical communication with said microprocessor, said keyboard including

a key guide; and

a plurality of keys, each retained laterally in said key guide and operable for providing input to the device when depressed by a switch-activation distance in a direction substantially perpendicular to a plane defined by said key guide;

wherein each key of said plurality of keys is rotatable about a respective axis of rotation substantially perpendicular to said plane.

26. The device of claim 25, wherein rotation of each key of said plurality of keys is controlled by said microprocessor based on at least one of a software application running on the device and a user input received at the device.

27. A method of arranging a keyboard of a handheld electronic device, the device including a microprocessor and a keyboard in electro-mechanical communication with the microprocessor, the keyboard including a plurality of keys, each key of said plurality of keys being rotatable under control of the microprocessor, the method comprising:

receiving a selection of one of a plurality of keyboard arrangements; and

controlling rotation of the plurality of keys, in accordance with said selected keyboard arrangement.

28. The method of claim 27, wherein said selection is based on at least one of a software application running on the device and a user input received at the device.

29. The method of claim 27, further comprising providing a user interface enabling selection from amongst said plurality of keyboard arrangements.

30. The method of claim 27, further comprising:

providing a user interface enabling configuration of a custom keyboard arrangement of said plurality of keyboard arrangements; and

receiving, via said user interface, a configuration of said custom keyboard arrangement.

31. The method of claim 27, further comprising:

providing a user interface enabling association of a software application with a custom keyboard arrangement of said plurality of keyboard arrangements; and

receiving, via said user interface, an association of said software application with said custom keyboard arrangement.
