In Part 1 of this interview, Engineering TV visited Jeff Bellinghausen, CTO and Chief Architect, at the Sixense studios in Los Gatos, California. Jeff gives us a run-down of their TrueMotion control system. The TrueMotion 3D controller from Sixense is an input device based on precise tracking relative to a base station and is able to react with pinpoint accuracy to movement in six degrees of freedom. Unlike a Wiimote or Sixaxis controller, the TrueMotion controller operates within a weak magnetic field rather than relying upon accelerometer technology. The degree of accuracy falls to the nearest millimeter, and is updated once every ten milliseconds. This results in a fluid, highly accurate input device that could revolutionize PC and console gaming, as well as lead to some fascinating applications in the engineering design, industrial and medical fields.
