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 a finger operated conveyor belt 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, including a bidirectional controller operated by one or more fingers fingers of said user, for producing a third signal indicative of a third position of said object on said display with respect to a third translational axis, said bidirectional controller including a belt operative to be bidirectionally moved by said fingers and having means or detecting bidirectional movement of said belt and converting the detected movement of said belt to said third signal, said belt being affixed to said housing in such a manner that said user can operate said belt equally as well when said device is stationary as when said device is being moved across a surface by said user;

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 bidirectional controller results in said third position of said object being defined on said display.

2. The device as recited in claim 1, wherein said belt has two broad side surfaces having a plurality of fingertip sized holes formed therein through which said fingers can be inserted.

3. The device as recited in claim 1, wherein said belt has a rough outer surface for engaging said fingers.

4. The device as recited in claim 1, wherein the bidirectional movement of said belt is unbounded.

5. The device as recited in claim 1, wherein said housing further includes a belt enclosure affixed to said housing for extending a portion of said belt away from said housing, said enclosure having an aperture through which said fingers can be inserted to engage said belt.

6. The device as recited in claim 1, wherein said belt is further affixed to said housing in such a manner that the physical direction of motion of said fingers operating said belt substantially corresponds to the direction of motion of said object with respect to said third translational axis.

7. The device as recited in claim 6, wherein said housing further includes a belt enclosure affixed to said housing for extending a portion of said belt away from said housing, said enclosure having an aperture through which said fingers can be inserted to engage said belt.

8. 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, including a bidirectional controller, for producing a third signal indicative of a third position of said object with respect to a third axis, said bidirectional controller including a roller operative to be bidirectionally moved by said fingers and having means for detecting bidirectional movement of said roller and converting the detected movement of said roller to said third signal, said roller being affixed to said housing in such a manner that said user can operate said roller equally as well when said device is stationary as when said device is being moved across a surface by said user;

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

9. The device as recited in claim 8, wherein said roller has a rough outer surface for engaging said fingers.

10. The device as recited in claim 8, wherein said housing further includes a roller enclosure affixed to said housing for extending a portion of said roller away from said housing, said enclosure having an aperture through which said fingers can be inserted to engage said roller.

11. The device as recited in claim 10, wherein said roller is further affixed within said enclosure in such a manner that the physical direction of motion of said fingers on said roller substantially corresponds to the direction of motion of said object with respect to said third axis.

12. The device as recited in claim 8, wherein said roller is further operative to be continuously moved in a direction by two fingers of said users in such a manner so as to continuously change the definition of said third position for said object.
