Abstract

Disclosed is a computer keyboard and cursor control system and method for use with a computer having a pointing device operated by a user. Upon determining that the user is operating the pointing device, the invention switches to a different keymap, so as to remap at least one typing key on the keyboard into other functional key(s) such as a “left mouse click” function button.

Claims

1. A method for switching functions of one or more keys of a computer keyboard, comprising the steps of:

activating a keyboard having a plurality of text typing keys, the keyboard being coupled to a pointing device that remains active at all times to permit a user to achieve instant manual control of a cursor on a display screen;

activating a first keymap for enabling the user to manually activate a text typing mode at the keyboard;

determining whether the user is operating the pointing device; and

deactivating the first keymap and activating a second keymap upon determination that the user is operating the pointing device, the second keymap operable to enable the user to manually activate a cursor mode at the keyboard;

whereby one or more keys of the keyboard are enabled by the second keymap to control pointing device functions.

2. The method of claim 1 whereby, upon activation of the second keymap, functions of selected text typing keys on the keyboard are switched into cursor control functions that are specified by an active application.

3. The method of claim 1 whereby neither the first keymap nor the second keymap is switched to another keymap while at least one key on the keyboard is held pressed.

4. The method of claim 1 whereby shortcut keys are detected and executed regardless of whether the first keymap or second keymap is activated.

5. The method of claim 1 whereby functions of at least one typing key on the keyboard is switched to enable mouse click functions upon activation of the second keymap.

6. The method of claim 2 whereby functions of at least one typing key on the keyboard is switched to enable window scroll functions upon activation of the second keymap.

7. The method of claim 1 whereby functions of at least one typing key on the keyboard is switched to enable page back/forward functions upon activation of the second keymap.

8. The method of claim 1 whereby functions of at least one typing key on the keyboard is switched to enable script execution functions upon activation of the second keymap.

9. The method of claim 1 whereby functions of at least one typing key on the keyboard is switched to enable launch application functions upon activation of the second keymap.

10. The method of claim 1 whereby functions of at least one typing key on the keyboard is switched to enable open file functions upon activation of the second keymap.

11. The method of claim 1 whereby functions of at least one typing key on the keyboard is switched to enable sound volume control functions upon activation of the second keymap.

12. The method of claim 1 whereby functions of at least one typing key on the keyboard is switched to enable display-brightness-control functions upon activation of the second keymap.

13. The method of claim 1 whereby an icon on the display screen indicates whether the first keymap or second keymap is activated.

14. The method of claim 1 whereby a light indicates whether the first keymap or second keymap is activated.

15. The method of claim 1 whereby the appearance of a cursor on the display screen indicates whether the first keymap or second keymap is activated.

16. The method of claim 1 whereby two sets each of the first keymap and second keymap are stored in a computer memory, one set configured for right-handed users and the other set configured for left-handed users.

17. The method of claim 1 whereby at least one separate mouse click button is provided in addition to the first keymap and second keymap.

18. The method of claim 1 whereby functions of at least one typing key on the keyboard is switched into special keys that change the functions of other keys upon activation of the second keymap.

19. The method of claim 1 whereby the first keymap is activated while a text-edit object is active.

20. The method of claim 1 whereby the second keymap is activated while no text-edit object is active.
