Thrixxx has demonstrated a sex game that is controlled using "Kinect," the motion-sensing control system from Microsoft. Thrixxx used open source tools to intigrate the device to work on a PC. Development is in the early stages, and so far the controller can only be used for a little casual groping and dildo action.
Thrixxx expects to fully commercilaze the product, eventually offering full control over sex games including virtual penetration, and will include voice cammands. Microsoft is not onboard with the idea to say the least, but Thrixxx is going to forge ahead, even if they have to release the product for free to avoid lawsuits. It's almost certain that the Kinect controller will eventually be available for use with existing sex games from Thrixxx including 3D Sexvilla, Hentai 3D, and more.
