Shown below is a a recent prototype "Go Prone" virtual-reality harness prototype designed for use with optical tracking devices.
It uses an original, highly overconstrained spatial mechanism whose redundant multiple constraint paths provide lateral and torsional stiffness along with strong force cues to the fully-immersed wearer. It also uncouples the vertical and rotational inertias.
It was designed by Roger Kaufman and built for the Naval Research Laboratory in the GW SEAS machine shop with the aid of Carl Behnke.
It has yet another innovative system of spatial compliant mechanisms which allows the user to jog without moving the major translational inertias.
It has laser cut parts which provide stiffness, lightness and manufacturing economy.
