An anonymous reader writes "Do we really need cable and/or video service operators knowing this? It seems cable operators at the semi-annual CableLab's Onnovation Showcase have informally voted (http://www.cablefax.com/cfp/just_in/Future-Gazing-at-CableLabs-Innovation-Showcase_37042.html) a product developed by Israeli company PrimeSense (http://www.primesense.com/) that can determine via a sensor in a set top box how many people are watching a TV as best new product.
The PrimeSense product 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."
