TVision raises $6.8M to take on Nielsen with thermal eye and emotion tracking tech

The company starts with a small device that sits on top of and works with your ordinary television. It does not read the world as we see it with an optical camera alone; it uses lasers and thermal infra-red so that it can pick up more data even when lighting conditions are low (as they often are when you are watching TV). Its sensors and algorithms are capable of identifying not just who is watching in a family group, but also who is just sitting in the room but not watching TV (instead playing on, say, a mobile phone), and what viewers’ reactions are to the show that is on at the time. – Ingrid Lunden, TechCrunch http://ift.tt/2ev15P5
