The airport's smart scoreboard displays information for a specific passenger.

At the airport in Detroit, a scoreboard appeared that displays flight information for 100 passengers at a time. They can all look at the same screen and see different information. The scoreboard screen, called Parallel Reality, is made up of pixels that project millions of light rays in different directions. The facial recognition system "directs" these rays to a specific person and displays information about his flight. The creators of the device say they wanted to make waiting for a flight more convenient - so that people do not feel lost and can instantly find their way without a smartphone.
