Coming to a giant airport screen: Your personal flight information

Inside a terminal at Detroit Metropolitan Airport, thousands of passengers a week are finding their way to gates using technology that looks like something out of a futuristic sci-fi movie.

Delta Air Lines recently introduced a “Parallel Reality” system that lets travelers access individual flight information on a shared overhead screen based on a scan of their boarding pass — or their face. The twist is that 100 people can do this at a time, all using the same digital screen but only seeing their own personal details…

In Detroit, an overhead motion sensor that tracks moving objects anonymously follows passengers after they scan their boarding pass or face to know where to direct flight information, Ng said. Travelers need to opt in to Delta’s facial recognition technology to use the face scan.
