Abstract

A three degrees of freedom interactive display controller device is disclosed, comprising a hand manipulable housing unit having an opening for the passage of a mouse ball, two motion detectors for detecting the movement of the mouse ball and converting that motion to output signals controlling the translational movement of an object on the display of a computer and at least one finger operated wheel or roller for controlling the translational motion of the object with respect to a third translational axis. All translation controls are operable to be physically moved in a direction which corresponds to the desired simulated direction of movement of the object on the display. The physical motion of each control is unbounded and the actual physical position of the housing unit is independent of the simulated position of the object on the display.

Claims

1. A device for providing signals indicative of an object'"'"'s location on a display, comprising:

a housing operative to be manipulated by a user;

a first translation position indicating means affixed to said housing for producing a first signal indicative of a first position of said object on said display with respect to a first translational axis;

a second translation position indicating means affixed to said housing for producing a second signal indicative of a second position of said object on said display with respect to a second translational axis; and

a third translation position indicating means affixed to said housing, said third translation position indicating means comprising at least two separately operable rotatably coupled bidirectional finger wheels, for producing a third signal indicative of a third position of said object on said display with respect to a third translational axis;

whereby a movement of said device over a surface results in said first and second positions of said object being defined on said display, and whereby a movement of said finger wheels results in said third position of said object being defined on said display.

2. The device as recited in claim 1, wherein said finger wheels are axially aligned.

3. The device as recited in claim 2, wherein said finger wheels are separated by a selection means.

4. The device as recited in claim 1, wherein said finger wheels are tangentially aligned.

5. The device as recited in claim 4, wherein said tangentially aligned finger wheels are translatable within said housing as a single unit.

6. The device as recited in claim 1, wherein the bidirectional movement of said finger wheels is unbounded.

7. The device as recited in claim 1, wherein said bidirectional finger wheels are affixed to said housing in such a manner that the physical direction of motion of said finger wheels substantially corresponds to the direction of motion of said object with respect to said third translational axis.

8. The device as recited in claim 7, wherein said third translation position indicating means further comprises:

a belt operative to be bidirectionally moved by rotation of said finger wheels; and

means for detecting the bidirectional movement of said belt and converting the detected movement of said belt to said third signal.

9. An apparatus for generating signals indicative of the three-dimensional position of an object, comprising:

an external housing;

a first translation position indicating means mounted to said housing for producing a first signal indicative of a first position of said object with respect to a first axis;

a second translation position indicating means mounted to said housing for producing a second signal indicative of a second position of said object with respect to a second axis; and

a third translation position indicating means mounted to said housing, said third translation position indicating means comprising at least two bidirectional finger wheels, for producing a third signal indicative of a third position of said object with respect to a third axis;

whereby movement of said apparatus over a surface results in said first and second positions of said object being defined, and whereby movement of any of said bidirectional finger wheels results in said third position of said object being defined.

10. The apparatus as recited in claim 9, wherein said finger wheels are translatable within said housing as a single unit.

11. The apparatus as recited in claim 9, wherein the bidirectional movement of said finger wheels are unbounded.

12. The apparatus as recited in claim 11, wherein said bidirectional finger wheels are affixed to said housing in such a manner that the physical direction of motion of said finger wheels substantially corresponds to the direction of motion of said object with respect to said third translation axis.

13. The apparatus as recited in claim 12, wherein said third translation position indicating means further comprises:

a belt operative to be bidirectionally moved by rotation of said finger wheels; and

means for detecting the bidirectional movement of said belt and converting the detected movement of said belt to said third signal.
