What's this, another fun tech demo from Sony? Just a few days ago we got a glimpse of the PS3VR library, which allows seamless zooming from far away to very, very close indeed. The company also showed off voice recognition tech and it's now applying the same idea to the PlayStation Eye, fulfilling earlier promises of advanced facial recognition for the PS3. It's called the Vision Library and, once a face has been analyzed, the machine can tell it apart from others, determine orientation, identify gender, tell what expression that face is... expressing, and then superimpose some big-eyed anime head right on top of it real-time. We fear this might take some of the fun out of cosplay night, but could make life rather more interesting for freaks with bovine fetishes. See for yourself after the break.
