Apparatus for natural torso tracking and feedback for electronic interaction

1. An apparatus for natural, three-dimensional torso tracking and feedback for electronic interaction, comprising:

a plurality of tethers each comprising a line with one end being affixed to an attachment point at a fixed location distal from the body of a human user and with another end being affixed to an attachment point proximal to the body of the human user, the proximal attachment point being configured to be worn or otherwise attached to the human user's person or clothing, and at least a portion of the distal attachment points comprising a sensor configured to measure at least strain of the affixed tether; and

a plurality of angle detection sensors, wherein at least a distal attachment point comprises an angle detection sensor configured to measure angular deflection of an affixed tether up or down with respect to a horizontal plane.

2. The apparatus of claim 1 , further wherein at least an angle detection sensor further comprises an angle measurement device configured to measure the precise angle of an affixed tether.

3. The apparatus of claim 1 , wherein an angle detection sensor comprises an electrical switch.

4. The apparatus of claim 3 , wherein the electrical switch comprises a mechanical leaf switch.

5. The apparatus of claim 3 , wherein the electrical switch comprises a rubber-dome switch.

6. The apparatus of claim 1 , wherein an angle detection sensor comprises a capacitive sensor.

7. The apparatus of claim 1 , wherein at least a distal attachment point comprises a mechanism for applying tension to an affixed tether.

8. The apparatus of claim 7 , wherein the mechanism comprises at least a pulley.

9. The apparatus of claim 7 , wherein the mechanism comprises at least a coiled spring.
