The company says (via CNet):
"The open-sourcing of device drivers for Kinect have enabled the...device to be used directly from connected PCs operating on Windows 7...The Kinect interface provides another exciting interface option for users of the sex simulation software to control the experience in extraordinary new ways. Controller-free is the next generation of game user interfaces, allowing users to use gestures, spoken commands, or objects to control in-game action that creates a completely new sex game activity and magical experience."
For now, the game just uses hand motions and gestures.
It is unclear whether ThriXXX's game will be even legal given Kinect's license agreement.
