       | The representative said there can be up to 100 people in this
       | large-ish rectangular area and each person can only see their
       | details and nobody else's (even as everybody moves around).
       | Everybody outside of the rectangle sees generic information.

       | I'm generally pretty good with figuring out how things work. I
       | could figure out the tracking piece, but I definitely didn't
       | figure out how they could so accurately make sure that I could
       | read my info everywhere within that box. There are some other
       | comments here that describe how it works -- pretty cool!
       | 
       | I was definitely amazed at how well this actually worked with
       | about 10 other people also testing it out. Privacy issues aside,
       | this is an amazing experience to be able to be on-the-move and
       | see a giant arrow that points you to exactly where you need to go
       | in an airport you're unfamiliar with.

       | which one applies to me. Airports are confusing monsters and
       | there's always an element of time pressure. This is brilliant.
       | 
       | Except the time until it gets used for something much more
       | dystopian is probably measured in hours now.

         | 
         | And this way it would be totally opt-in by installing the app.
         | 
         | I know this tech is also opt-in, however, the facial
         | recognition itself is seeing everyone, even the people who
         | haven't opted in, and is probably tracking them. Just doesn't
         | know who they are.

           | 
           | So it's not reading your face in front of the display to
           | determine what to show, but rather you scan your pass and
           | verify your identity, then walk around the airport where it
           | tracks your position to keep track of who you are and where,
           | and when you then stand in front of this display it knows
           | where you are relative to the display which can deliver a
           | directionally targeted image to your eyes.

           | ... that describes a lenticular lens array. Each lens takes a
           | section of the screen and projects it out just as a projector
           | does. A lenticular array of cylindrical lenses does it in
           | only one dimension. It's possible they are using a microlens
           | array to do it in two dimensions instead of one, but the
           | concept is very similar and also not unique.

       | show different information depending on where you're standing,
       | but I don't imagine this works perfectly. Second, facial
       | recognition is creepy. Some comments are arguing that this isn't
       | a problem because you're already being tracked anyway by other
       | cameras around the airport. But just because it's already
       | happening doesn't make it okay. Third, it seems technically
       | impractical. It takes the relatively simple task of picking a
       | flight out of a list and turns it into something brittle and
       | error prone.
       | 
       | I get that the technology is impressive in a way. And my first
       | two points are perhaps less concerning since the Delta program is
       | opt in. But overall it seems to cost more than it's worth. Maybe
       | that makes this more of a marketing gimmick than anything.

         | this board (which ostensibly only you or someone directly in
         | your space can see), especially when someone can go to a random

               | think people expect water tight personal information
               | security. But I do think people have an expectation of
               | _privacy_. The example you gave is illustrative. You said
               | someone can ask you for your first name. If they 're an
               | airline employee, fine. That's necessary for them to run
               | their business properly. But if they're a stranger on the
               | street, you're perfectly entitled to tell them to get
               | lost. Now let's consider that a hypothetical, non-opt-in
               | PI display in an airport would be rather like a stranger
               | walking up and asking you for your first name. Yes,
               | there's not much actual threat in giving it. But who
               | would want to do that? No one. I'm not sure I could say
               | why, but I don't think it's fair to ask why and I don't

               | I think it's important to take into account these kinds
               | of "first-person" concerns that have a sort of common
               | sense to them. You might be able to diffuse them from a
               | strictly logical point of view. But that doesn't do away
               | with the fact that an average person would still have the
               | concern. And maybe there's an unseen logic in the common
               | sense viewpoint.
