In fairness people can already see where you're going at an airport. Almost everyone sits at the gate for their flight if they're not waiting in a lounge. And it's not points but frequent flyer status. Minor distinction sure.

Which they also already more or less see (modulo credit cards and other ways you can board early).

Exactly. This isn't privacy preserving but it's also opt-in and shows stuff that's already fairly obvious to people at the airport.

Isn’t the idea of the tech that only the intended person sees it? When I’ve walked by I haven’t caught a glimpse of anyone’s info. I haven’t walked up close to a person viewing it though. It must have some FOV that allows “spying”.

The point of this technology is that the 20 people behind cannot see the same thing you do. This isn't just "Jane is walking past, let's display Jane's information on the TV now". The point is that this technology has pixels that selectively beam Jane's information to Jane and only Jane, while simultaneously beaming OtherPerson's information to OtherPerson and only OtherPerson.

It's very cool technology. The one thing I don't see any information on is how precise it can be (like if I'm standing directly next to Jane rather than 15 feet away, will I see Jane's info?).

Since we don’t see any details on the precision, it’s hard to make the statement that others can’t see your information. If this is a lenticular display, then anyone standing in your line of sight will see what you see.

I’m more concerned about protecting my privacy from organizations, but I think privacy concerns regarding other viewers can be addressed by not displaying anything personally tied to you. The name is cute for a demo, but I don’t need to see my name, just my flight. I’ll know it’s mine.

Interesting, thanks. I wonder how narrow the angle of personalized viewing is.

This is me just completely guessing, but I would assume it's probably pretty close to how close someone would need to be standing next to you to see the same information on the phone.
