He’s spent the past three years developing new camera software that scans facial expressions to identify fan behaviors — think cheering, jeering, talking on a cell phone — in real time at a stadium. So a company can measure, for example, how many eyeballs are attached to a Jumbotron ad (are fans looking?) and how well it’s being received (are they laughing? Smiling? Fiddling on their phones and ignoring it?).

this type of technology is by no means benign, they already use simalar tech to monitor boarder check points to look for signs of nervousness.
