This futuristic tech is now available in Detroit.

Immediately after going through security at Detroit’s Metro Airport earlier this week, I encountered Delta Air Lines’ new Parallel Reality experience. I’d read about the amazing technology earlier this summer when it debuted, and have since been intrigued. Essentially it personalizes one of the large airport flight information screens just for you. In fact, you are the only person who can see your information up on the screen above you – sort of.

My wife and I saw an attendant by the kiosk. So we stopped and asked how it works. He had me scan my digital boarding pass into a machine at the kiosk, and then scan my face. “Okay, just step up to the flight information screen and look up,” he said. Instantly I saw what had been a blue screen with an airplane image on it instantly change to “Hello Scott” in large letters, with all of my flight information below that – including my gate number and an arrow pointing me in the right direction. Standing three feet away, my wife said she didn’t see anything. So the attendant had her move right up to me and look up. “Oh wow,” she said. “That is so cool.” Please understand that my wife is never awed by technology. Like ever. So for her to respond in this way was a breakthrough.

The voluntary experience was truly mind-bending, and I can definitely see the possibilities for it in the future. Currently this is the only place in the world where you can experience the technology, according to Delta, which is testing it at DTW.

The parallel reality display allows up to 100 customers to each see their personalized flight information on that one digital screen — simultaneously, mind you. And yes, each customer who opts in can see only his or her own flight information. It’s designed to create a more streamlined and personalized airport experience for customers, allowing them to navigate the airport with more ease and eliminate the need to search for a specific flight among the many rows on a typical departure board. And for the moment, Delta passengers can scan either a digital or paper boarding pass to experience this seamless process.

According to Delta, the proprietary multi-view pixel technology within the display 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. An overhead sensor detects your presence and location, using anonymous non-biometric object detection. In other words, the sensor sees you as an object without recognizable features – and without facial recognition. As you move around, the overhead sensor continually shifts your private zone to your current location. This allows you to see your own personalized content even as you move within the viewing area.

Delta says that future applications of the technology could exist at stadiums, shopping centers, entertainment venues and more. I’ve heard that retail stores have been working on digital ads that are personalized to each passerby, via their smartphone. I’d kind of doubted the validity of such technology, until I saw it first-hand this week. If Delta is somehow able to eliminate the boarding pass scan part of the process – and everyone sees their information without having to stop at the kiosk – it could make navigating strange and foreign airports much less stressful.
