Abstract

A computer keyboard may include an assembly for scrolling and navigating an image in multiple directions relative to a display screen. A computer keyboard may include an assembly for control of a graphical object, insertion point or mouse cursor in multiple directions relative to objects on a display screen. Two control devices are provided onto each side of a computer keyboard. The devices are configured such that both control a graphical cursor. One device controls a graphical cursor and the other device controls view scrolling of an image. In yet another aspect, the functionality of the devices for cursor control or view scrolling is selectable.

Claims

1. A computer keyboard configured for navigation of a graphical user interface of a host computer, comprising:

means for permitting scrolling of content items of a display screen relative to the display screen along a first axis so as to change the direction of scrolling to movement of said content items along a second axis when scrolling along said second axis exceeds a predetermined elapsed time, said second axis being perpendicular to said first axis; and

an input device for receiving manual movement and responsive thereto moving a graphical pointer relative to the perpendicular axes; and

an alphanumeric section being laterally disposed between the means and the input device.

2. The computer keyboard according to claim 1, wherein the means includes a trackball assembly including a spherical member being rotatably configured to receive the manual movement;

and a scrolling sensing system that determines when said spherical member is rotated for scrolling along one of the first or second axes.

3. The computer keyboard according to claim 1, wherein the means includes a spherical member being rotatably configured to receive the manual movement;

and a scrolling sensing system being configured to sense a transition state of the spherical member when the member is rotated for a first directional scrolling along the first axis and responsive to the transition state change to a second directional scrolling along the second axis.

4. The computer keyboard according to claim 1, wherein the means includes a spherical member being rotatably configured to receive the manual movement;

and a scrolling sensing system being configured to sense a transition state of the spherical member when the member is rotated for scrolling along one of the first or second axes.

5. The computer keyboard according to claim 1, wherein the means includes a spherical member being rotatably configured to receive the manual movement;

and a scrolling sensing system that determines when said spherical member is rotated for directional scrolling along one of the first or second axes to a threshold level after a transition state of the directional scrolling so as to maintain said scrolling.

6. The computer keyboard according to claim 1, wherein the means and the input device each include a trackball device.

7. The computer keyboard according to claim 6, wherein the means includes a scroll wheel assembly.

8. The computer keyboard according to claim 1, wherein said first means includes a touchpad.

9. The computer keyboard according to claim 1, wherein the means includes a touchpad and the input device includes a trackball device.

10. The computer keyboard according to claim 1, wherein the means includes a trackball device and the input device includes a touchpad.

11. The computer keyboard according to claim 1, wherein the scrolling is responsive to voice input.

12. The computer keyboard according to claim 1, wherein the means permits adjusting a size scale of a said content item of a display screen.

13. A computer keyboard configured for navigation of a graphical user interface of a host computer, comprising:

a keyboard housing;

means for permitting scrolling of content items of a display screen relative to the display screen in one of a vertical direction and a horizontal direction so as to change the direction of scrolling to movement of said content items along the other of one of the vertical and horizontal direction when scrolling along the other of one of the vertical and horizontal directions exceeds a predetermined elapsed time;

an input device for receiving manual movement and responsive thereto configured for moving a graphical pointer relative to two dimensions of the image display screen; and

an alphanumeric section being disposed between the means and the input device.

14. The computer keyboard according to claim 13, wherein the means includes a movable ball and a scrolling sensing system that determines when said movable ball is rotated for the vertical scrolling and the horizontal scrolling.

15. The computer keyboard according to claim 13, wherein the means includes a movable ball and a scrolling sensing system being configured to sense a transition state of the movable ball when the ball is rotated for vertical scrolling and responsive to the transition state change to horizontal scrolling.

16. The computer keyboard according to claim 13, wherein the means includes a movable ball and a scrolling sensing system being configured to sense a transition state of the movable ball when the ball is rotated for horizontal scrolling, and responsive to a change in the transition state, changing said horizontal scrolling to vertical scrolling.

17. The computer keyboard according to claim 13, wherein the means includes a movable ball and a scrolling sensing system that determines when the movable ball is rotated for vertical scrolling to a threshold parameter after a transition state of the horizontal scrolling so as to maintain said vertical scrolling.

18. The computer keyboard according to claim 13, wherein the means includes a movable ball and a scrolling sensing system that determines when the movable ball is rotated for horizontal scrolling to a threshold parameter after a transition state of the vertical scrolling so as to maintain said horizontal scrolling during said rotation.

19. The computer keyboard according to claim 13, wherein said input device comprises a touchpad.
