Today is Demo Day for TechStars NYC . I'll be at the event, but here is a little preview from when I visited last week . TechStars organizers David Cohen and David Tisch showed me around the New York office. In this video, I get a peak at a smart digital sign being developed by Immersive Labs and a very cool learning app from a startup called Veri . The digital sign is a large flat screen display with a camera on top that detects the faces of people who stop and look at the signs. It tries to determine gender, age, distance from the sign and how long each person is paying attention. Software then tries to serve up the most relevant ads based on whether it thinks more men or women are looking at it, and other factors. Yup, this is exactly the kind of thing that leads to a Minority Report type of world.
