TIL Delta Airlines has a “Parallel Reality Zone” in the Detroit Airport that allows customers to see their personal flight informations AND ONLY THEIR FLIGHT information on the same screen and the same time.

1. > HOW IT WORKS

   >The proprietary multi-view pixel technology within PARALLEL REALITY displays can direct different-colored light to each of many viewing zones, allowing multiple people simultaneously looking at the same display to each see their own unique, personalized content.

   >Customers must opt in at the registration kiosk to engage with the experience. Once you opt in, a private viewing zone is created at your location, and the display directs relevant flight information to that zone.

   >An overhead sensor detects your presence and location, using anonymous non-biometric object detection (the sensor sees you as an object, without recognizable features).

   >As you move around, the non-biometric overhead sensor continually shifts your private zone to your new location. This allows you to see your own personalized content even as you move within the viewing area.

   >Once you exit the PARALLEL REALITY experience viewing area, you must opt in again at the registration counter to see your personalized flight information again.

   Neat. I wonder how governments and corporations will abuse it.

2. I remember hearing about some company working on essentially the same idea, but for audio instead. It’s called sound beaming
