PrimeSense, the folks behind the guts of the Kinect and other motion-sensing tech, has unveiled a cheaper and tinier 3D sensor that could bring motion sensors to a whole different class of products. Dubbed the Capri, the new system-on-a-chip is about ten times smaller than existing sensing devices — not only can it be embedded in tablets and laptops, it’ll likely fit in a mobile phone as well. The company will be showing it off come CES and samples will be available for OEMs starting mid-2013. If this means we can go all Jedi mind trick and wave our hands over our phones to shut it off, then we’re definitely looking forward to seeing this in action. Seriously, because there’s no picture to be had at the moment.
