Prime Sense: Winner of the informal best new product vote idea, the vendor’s tech lets digital devices see a 3-D view of the world. In other words, that cable set-top box will know whether 3 people are sitting on the sofa watching TV and how many are adults vs children. It all happens via a chip that resides in a camera that plugs into the STB. The images look more like something from thermal imaging. The 3D-sensor works as a gestural control device (enhancing or replacing what a traditional remote control does), allowing consumers to operate their cable-box through simple hand motions from the comfort of their sofas. The tech uses a camera attached to the STB in a similar vein to IR and motion sensors used to turn on/off lights, etc, to sense when someone is in the room.
