Named Gametrak Fusion, it uses a patent-pending ultrasonic and RF system to track the motion of a Wii-Mote-style controller, using a small base unit on the floor in front of the player. A 3D accelerometer in the controller also provides data on absolute position and orientation.

Combined together, the company claims it is both more accurate and more flexible in terms how it can be applied to games than Wii’s technology. For example, it offers better range and isn’t affected by ambient lighting conditions. Perhaps more interesting however, because the USB-based system is expected to be available for PlayStation 3, Xbox 360, and PC platforms, it will provide a potential secondary market for publishers who have developed custom games for the Wii’s hitherto unique controller system. Indeed, In2Games’ managing director Elliot Myers goes so far as to refer to Fusion as providing Wii emulation, albeit with the proviso that it’s more capable.
