PixMob ( https://pixmob.com/en/ ) has been used in past superbowls to create similar effects, which aparently uses IR.

Yes, PixMob also produced synched LED bracelets for Taylor Swift's most recent tour. Here's a video of that in action [1] and a video showing various events they've been at [2].

I'd be tempted to think they decided to solve the logistics challenge instead of the technical one. So instead of trying to build a generic piece of hardware that detects its own position and lights up accordingly, each torch was unique (or configured via software to be unique, even if at "runtime") and configured specifically for its exact position on the field. If each torch is designed for it's own show, then the…

so are you saying all those people are not some random spectators of the show but super bowl crew? Or random spectators who guarantee that they wont move from their predefined position?

The people holding them had some synched up dance moves, so they definitely had practice

The audience was doing choreographed moves during certain songs, so it was not random at all.

but didn't the torches move out when they had the sort of starfish shaped formation and they were all yellow? seems hard to believe they would've been able to coordinate the extras moving far away and then moving right back in position. What about something low tech like: the field has a grid with infrared emitters pointing up spaced let's say 6 feet apart, when changing positions extras have to keep the torch vertic…

It isn't that hard to coordinate professional dancers to do what they did.

I figured the dancers were just doing it manually.

edit: after a few rewatches, there's definitely a few places where (non-Chinese) human timing seems unlikely but I'm still hoping it was manual.

RAIN Rfid can do this for moving objects: https://www.youtube.com/watch?v=p1LykdRWTfk

View Technologies can track a moving RAIN Rfid tag to the size of a softball in a xyz plane in realtime.

Yeah, don't overthink the starfish pattern. There were radial and linear sweeps that were probably RF time-of-flight controlled, but not that part.

I don't think they were professional dancers, but I also don't think they were random people. Screened and rehearsed locals seems the most likely.
