Sensor To Monitor TV Watchers Demoed At Cable Labs

An anonymous reader writes "Cable operators at the semi-annual CableLab's Innovation Showcase have informally voted as best new product a gizmo that can determine how many people are watching a TV. Developed by Israeli company PrimeSense, the product lets digital devices see a 3-D view of the world (the images look like something from thermal imaging). In other words, that cable set-top box will know whether three people are sitting on the sofa watching TV and how many are adults vs. children. Do we really need cable and/or video service operators knowing this? It all happens via a chip that resides in a camera that plugs into the set-top box."

      I suspect the actual uses of the device would be for advertisers to get some feedback and makeup of their viewing audience. The blurb linked to suggests it can tell between kids and adults. That doesn't sound like a tech to limit the number of viewers, that sounds like a tech to see "okay, how many kids versus how many adults are watching right now? More kids? Awesome, McDonalds pays more to run happy meal ads than value meal ads."

      Some years ago, I developed a small box for the research organization in one of the cable companies that monitored the IR remote control to track button presses and did screen grabs of the STB output in order to allow in-home monitoring of customers' use of the various UI features (needed both because the STB in question was notorious for missing button presses). One version of the little box added a camera pointing out at the viewers and grabbed those images at the same time. The original intent was to allow researchers to check who was in the room when strange button sequences were encountered in the data; while testing the box in a researcher's home, the odd sequences turned out to occur when the three-year-old got her hands on the remote control. The human factors types loved having the snapshots available; again during in-house testing, the image sequences jogged peoples' memories: "Yeah, Bobby was there and that was when this odd thing happened..."

      The version that took pictures of viewers never got used in customers' homes. The legal department was seriously concerned about how to write an agreement regarding the use of those images. I certainly have to wonder whether Comcast's legal department has looked at what needs to be added to the terms of service, and what the privacy requirements will be. If I believe my spouse has been cheating on me, can I get access to what was observed while I was out of town?

      The members of the research group and I did have some odd conversations about whether the viewer snapshots should be disabled based on which channel was being watched...

      On the contrary. I bet it does.

      One of my graduate professors at the University of Missouri is doing some work with elder care with technology like this. Getting real 3-D information from multiple cameras takes a lot of processing time, but they can segment the space in a room down to 1 inch cubes. The result is a 3-D silhouette of the objects and people moving in the room. They can tell the difference between people moving throughout the room. A small child is different from a dog in that the dog has 4 legs, for example.

      They can identify whether a person is laying on the couch or has fallen. They can extract information such as the bend of the spine and whether a person favors one leg or the other. A silhouette of a cardboard cutout would appear flat to the camera.

      What I described above is PHD research using some fairly complex computer vision, 3-D segmentation and pattern recognition algorithms. 3-D scene reconstruction cannot be done with a single camera. The math doesn't work. I would not expect a set-top box with a single webcam to be that good. I would, however, expect them to do motion segmentation on frames of video. Background subtraction would let them ignore the furniture in the room and identify regions of motion. From there, pattern recognition algorithms could be used to find faces and identify the relative shape of a body based on a template. Given that, you could identify whether a person was tall or short and the relative proportions of their bodies. You probably couldn't identify male or female, though. That would be a tough call. You probably could identify a dog versus a child with relative ease.

      Luckily, the amount of bandwidth needed to send these images back to the cable company would be pretty massive (given everyone who watches cable in a small to medium sized city) so you shouldn't worry about that. You probably only need to worry about packets being sent back over the cable line identifying the date, time, number of adults, number of children, channel and number of seconds since the last channel change.

      Ratings companies like Nielsen have been using "people meters" for years now. However the current technology relies on household members pressing a button to register their presence in the room. Nielsen experimented with infrared sensors over twenty years ago. Trust me, this is hardly new technology.

      Of course, becoming a member of one of the Nielsen meter panels depends on your agreeing to participate. A system where one is automatically monitored by a set-top box with or without prior agreement raises enormous privacy issues.
