Gaming mag Gamasutra has an interesting interview up with In2Games’ Harry Holmwood about the company’s forthcoming Gametrak Fusion controller. Designed to bring motion-control the PS3 and Xbox 360, the Fusion combines an accelerometer with ultrasonic tracking in order to provide both movement and position-awareness regardless of the orientation of the controller device.

The Fusion was announced in 2006 and is due to hit the market in Q3, according to the company. Like all 3rd party attempts at adding motion sensing to an existing platform, success will rely upon the creation of an ecosystem of games and controller devices that appeal to a large enough market — certainly Wii has proven the value of motion control in the overall market, so it probably comes down to In2Games’ ability to execute their strategy. We’ll be following up on this, as we’re particularly intrigued by the mix of relative and absolute positioning and the use of ultrasonic instead of infrared for the absolute side of the equation.
