The great smartening of the idiot box continues. It was several years ago that we started seeing the first internet-connected TVs, and since then TV makers have been adding more and more slightly useful features, generally one or two per generation — it wouldn’t do to put them all out at once, of course. And while much functionality is still left to the set-top box, media player, or console, it seems inevitable that these increasingly capable display devices will integrate things we consider cutting-edge today.Take gesture controls, for instance. Microsoft’s hit gaming peripheral, the Kinect, has made people aware of the possibilities of motion tracking and depth-sensing cameras, though it’s often hacks that really deliver on the potential. PrimeSense, who contributed much to the development of Kinect, is hoping to combine this next-gen interface with next-gen display hardware.
