The below video shows Canesta's new 3D gesture control system, which it's hoping to sell soon with help from Hitachi and GestureTek. The idea is to build the sensors into media devices such as game consoles or Apple TV-like gear to give your remote control a rest.
It's a pretty cool idea, and according to the accompanying press release, it should be a low-cost product. We're not sure when--if ever--this will make its way into living rooms, but the know-how is there. If this Canesta video and Microsoft's E3 announcements prove anything it's that the technology is ready, too.
