ASUS may not be anywhere close to ready for its Wavi Xtion to hit retail shelves (we're hearing Q2 of 2012), but that didn't stop our brethren over at Engadget Spanish from stopping by for a hands-on demonstration at CES. We'll spare you the details on how it works, but in practice, we learned that it's quite similar to Kinect. Not shocking considering that PrimeSense is behind both boxes, but the primarily difference seemed to be the reaction time. ASUS' solution wasn't quite as snappy as the Kinect, being slower to recognize and translate motions in testing. Of course, we wouldn't expect a product that's 18 months out from mass production to be completely on top of its game, but feel free to head on past the break to see exactly what we mean.
