"I guess it was only a matter of time." That's how adult-game maker ThriXXX sums up its latest project, a sex game that uses the Xbox 360's motion-sensing camera to let users fondle virtual females.

　　Viewable via a risque YouTube video, a demonstration of the game--still in its early stages--shows a user controlling the onscreen action with just his hand. The control scheme was set up by attaching a Kinect to a Windows 7 computer with an open-source Kinect driver installed. Similar drivers have been used for more scientific pursuits using Kinect.

　　Open-source drivers are allowing sex-game creators to use Kinect in ways Microsoft did not intend.

　　"The Kinect interface provides another exciting interface option for users of the sex simulation software to control the experience in extraordinary new ways," ThriXXX said in a statement provided to GameSpot sister site CNET. "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."

　　According to the YouTube page, ThriXXX is "currently in development of adult-themed Kinect games for the Microsoft Xbox 360 and or PC." How such a game could ever come to the Xbox 360 is unclear, as Microsoft does not allow Adults Only-rated games to be distributed on its console.

　　In a statement, Microsoft said the following: "This isn't the first example of a technology being used in ways not intended by its manufacturer, and it won't be the last. Microsoft did not authorize or license its technology for this use and will take appropriate action against violations of its intellectual property. Xbox is a family-friendly games and entertainment console and does not allow Adults Only (AO) content to be certified for use on its platform and would not condone this type of game for Kinect."
