I would imagine that the at system at MSG is similar to Ingenuity Sun Media's system that's been deployed across NASCAR[0]. (The NYT article doesn't identify the vendor, but how many are there?) ISM's system specifically looks at the number of people in the crowd and how many are looking at the screen. Additionally, it tries to identify demographics in the crowd. Which makes sense, because this is meant for mass advertising. Although, I wonder how much more accurate you're going to get with some geewiz face scanner, than traditional demographic information sources. (Lots of middle aged white men at NASCAR? You don't say!) Update: Apparently, you can get better info. > "We've learned the age demographic is more diverse than we thought it would be," Hutchins said. "We're seeing a very balanced male-female [ratio], we're seeing a very balanced adult-young adult [ratio], and we're seeing a bigger crowd than they told us we would see."[1] [0] https://jalopnik.com/the-video-boards-at-nascar-races-are-scanning-your-face-1823610364 https://jalopnik.com/the-video-boards-at-nascar-races-are-sc...
