Abstract

A scroll wheel assembly for computer input device having a housing. The scroll wheel assembly includes a housing and an engagable scroll wheel. The scroll wheel is rotatable with a shaft to preferably cause vertical scrolling of an image on a display. The scroll wheel is laterally tiltable relative to the housing and the shaft. A sensor is preferably positioned within the housing for sensing tilting of the rotatable member. In response to sensed tilting movement of the rotatable member, the image is horizontally scrolled, preferably in the direction of the lateral movement. The computer input device having the rotatable member may take the form of a keyboard, a mouse, a trackball device, or another type of computer input device.

Claims

1. A computer input device for scrolling an image, the device comprising:

a housing having an opening;

a finger-engagable control member provided within the housing and having a portion extending through the opening permitting user manipulation thereof, the finger-engagable control member being endlessly rotatable about a rotating axis extending within the housing and tiltable about a tilting axis;

a rotation sensor for sensing rotation of the finger-engagable control member; and

an optical tilt sensor for sensing tilting of the finger-engagable control member.

2. The computer input device of claim 1, wherein when the finger-engagable control member is rotated, a signal is transmitted to scroll the image in a first scroll direction and wherein when the finger-engagable control member is tilted, a signal is transmitted to scroll the image in a second scroll direction, the second scroll direction being approximately perpendicular to the first scroll direction.

3. The computer input device of claim 1, further comprising a tilt axle, wherein the optical tilt sensor includes an encoder mounted to the tilt axle and the optical tilt sensor is positioned at a rear of the finger-engagable control member.

4. The computer input device of claim 1 wherein the optical tilt sensor comprises a light source, a light sensor and a movable intervening member between the light source and the light sensor.

5. The computer input device of claim 4 wherein when the finger-engagable member is tilted in a first rotational direction, the movable intervening member moves in the same rotational direction.

6. The computer input device of claim 1 further including:

a carriage containing at least a portion of the finger-engagable control member; and

a tilt axle operatively connected to the carriage along the tilting axis, wherein the optical tilt sensor is located at the rear of the finger-engagable control member underlying the tilting axis and includes a light source, a light sensor, and a movable intervening member between the light source and the light sensor, the movable intervening member being operatively connected to the tilt axle.

7. The computer input device of claim 6 wherein the carriage may be rotated irrespective of tilting.

8. A system comprising:

an input device for scrolling an image, the input device including;

a housing; and

a finger-engagable control member provided within the housing and having a portion extending through the opening permitting user manipulation thereof, the finger-engagable control member being endlessly rotatable about a rotating axis extending within the housing and tiltable about a tilting axis;

a rotation sensor for sensing rotation of the finger-engagable control member;

an optical tilt sensor for sensing tilting of the finger-engagable control member; and

a controller in communication with the input device configured to generate a signal to scroll an image in a first direction responsive to rotation of the finger-engagable control member and to generate a signal to scroll an image in a second direction responsive to tilting of the finger-engagable control member, the second direction being perpendicular to the first direction.

9. The system of claim 8, wherein the tilting axis is perpendicular to the rotating axis, the rotation sensor senses rotation of the finger-engagable control member about the rotating axis and the optical tilt sensor senses tilting of the finger-engagable control member about the tilting axis.

10. The system of claim 8 further comprising a tilt axle, wherein the optical tilt sensor includes an encoder mounted to the tilt axle and wherein the optical tilt sensor is positioned at a rear of the finger-engagable control member.

11. The system of claim 8 wherein the optical tilt sensor comprises a light source, a light sensor and a movable intervening member between the light source and the light sensor.

12. The system of claim 8 further comprising

a carriage containing at least a portion of the finger-engagable control member;

and

a tilt axle operatively connected to the carriage along the tilting axis, wherein the optical tilt sensor is located at a rear of the finger-engagable control member underlying the tilting axis and includes a light source, a light sensor, and a movable intervening member between the light source and the light sensor, the movable intervening member being operatively connected to the tilt axle.

13. The system of claim 12 wherein the carriage may be rotated irrespective of tilting.

14. The system of claim 8, wherein the first direction is a vertical direction along a display screen and the second direction is a horizontal direction along the display screen.

15. A computer input device for scrolling an image, the device comprising:

a housing having an opening;

a finger-engagable control member provided within the housing and having a portion extending through the opening permitting user manipulation thereof, the finger-engagable control member being endlessly rotatable about a rotating axis extending within the housing and tiltable about a tilting axis;

a carriage for housing at least a portion of the finger-engagable control member and being tiltable about the tilting axis;

a shaft extending from the carriage;

a light-blocking member coupled to the shaft; and

a tilt sensor configured for sensing a position of the light blocking member.

16. The device of claim 15 wherein the tilt sensor includes a light source and a light sensor that is configured to sense light from the light source.

17. The device of claim 16 wherein the light-blocking member is configured to block transmission of light between the light source and the light sensor.

18. The device of claim 16 wherein tilting the finger-engagable control member along the tilting axis causes corresponding tilting of the carriage.

19. The device of claim 16 wherein when the finger-engagable member is tilted in a first rotational direction, the light-blocking member moves in the same rotational direction.

20. The computer input device of claim 15 wherein the tilt axle is operatively connected to the carriage along the tilting axis, and wherein the optical tilt sensor is located at a rear of the finger-engagable control member underlying the tilting axis and includes a light source and a light sensor, the light-blocking member being arranged between the light source and the light sensor and the light-blocking member being operatively connected to the tilt axle.
