The announcement of a new controller-free, motion-sensing interaction device so soon after the release of Microsoft’s Kinect may seem like blatant coat-tail riding, but it’s hard to complain when the company doing the announcing basically created the Kinect.  PrimeSense, the people behind the Kinect’s dark sorcery, is teaming with Asus to bring a similar gesture-based control system to PCs.

The device is (unfortunately) called the WAVI Xtion, and uses PrimeSense’s Immersive Natural Interaction technology to enable gesture-based controls for PC applications.  Whereas the Kinect is geared toward gamers, the Xtion will focus more on multimedia applications. 

The Xtion will be complemented by the Xtion PRO, “the world’s first PC-exclusive 3D sensing professional development solution,” designed to allow developers “to easily create their own gesture-based applications and software.”  Both will be unveiled at this month’s CES event in Las Vegas.

While the system may not be focused on games, the “Xtion Online Store,” expected to launch sometime after the devices’ Q2 2011 launch, will offer applications built on the Xtion PRO platform.  Let enough developers work on whatever they want, and they’ll inevitably make some games.  Maybe even some good ones.
