Claims
- 1. A position control device comprising:
- a plurality of grooved segments each presenting a longitudinal void therethrough,
- an annular band for supporting said segments and holding said segments in adjacent annular array to permit a user to apply a rotational force on at least one of said segments to accomplish rotational movement of said segment for communication of said rotational force to a detector and to permit a user to apply a lateral force to at least one of said segments to accomplish lateral movement of said segment for communication of said lateral force to a detector,
- means for detecting lateral movement of at least one of said segments,
- means for detecting rotational movement of at least one of said segments, and
- means responsive to said detected segment movement for generating a signal to effect repositioning of a symbol on a graphic display device.
- 2. The device as claimed in claim 1 wherein said rotational movement detecting means is a counter for quantifying the rotation of at least one of said segments.
- 3. The device as claimed in claim 1 wherein said lateral movement detecting means is a counter for quantifying the lateral movement of said plurality of segments.
- 4. The device as claimed in claim 1 wherein said means responsive to said detected movement generates an electronic signal to accomplish repositioning of a graphic display device.
