How Concert LED Wristbands Work | WSJ Tech Behind 

Even in Celine Dion tour in 2019-20, they used drones that changes colours and moves extensively.

as soon as i heard that they used IR i thought it was such a bad idea... IR requires you to be in line of sight for it to work. Then I saw them mask the signal with a gobo to make shapes i thought it was such a brilliant idea. They literally took a disadvantage of the technology and made it into an advantage.

@@bwoogie I thought the same way too 😅

Now that I know how they work, I can’t wait to draw a giant weener in the crowd!

Supreme Court Justices in the US should only have 16 year terms

lol

Oil - is plant based

Hello, do you know any specific website which shows upcoming concerts in Germany?

The microchip is obviously not biodegradable

@James Stevens notice the " organizers told us" if he would believe that there is compostable plant based plastic - he'd just state it as a fact.

These wristbands are made from PLA

Lol right! Came here to point that out. Horrible research by news agency

@@stayupthetree It's not horrible research, it's PixMob probably being under an NDA - why do you think it it shows you the connection right then?

@@rosonowski well trees aren’t capable of critical thought 😂

@@rosonowski it doesn't matter that PixMob is under NDA, the point of a news agency is to do independent research. It's clear that here they did not bother to investigate.

@@MrNoipe or maybe it's because them disclosing information that their interviewee is not supposed to hand out can get people in trouble, regardless of whether or not this information was provided by the interviewee themselves? laws are very complicated beasts, and companies generally do not want to accidentally break them just so they can say stuff everyone already knows

I still have mine from that concert!

That tour was so amazing

When your music sucks so much that you have to strap gimmicks onto the audience to keep them awake.

They were ahead of the game, stadium kings fr

yes, you are right...

At least those celebrities who tell us to save the planet don't feel guilty about the mountains of waste they create.

Same! I have Twice one! It was so beautiful to see!

My bro went to a Taylor Swift show ? Sus.....

@@sanynava9160going to concert makes u gay now?😭😭

@@sanynava9160 bro needs to touch grass

@@sanynava9160and what. she’s an amazing performer

@@jamesssharpe okay heshe

No they don't

No way these kinds of things are reused. Probably so cheap to mass produce.

This was my first thought about this. Cool experience, but this is an INSANE amount of ewaste being created! Like, a semi trailer full of landfill every show

When we went to a Coldplay concert, there were people by the exit to collect these after the concert was over.

I kept it to make it work again.

the implementation is innovative, the technology is ancient

nope, Coldplay might've been the first ones to use it in the USA. other's have used this in Korea/china waaaaay before that, even in the 90s

@@LuizHartkopf I’m not sure what technology they were using in the 90’s, but I’m referring to the specific technologies that Coldplay now has the patents for, and allowed the technology to be used in even more innovative ways than similar examples previously. Also I feel it necessary as a Brit to point out Coldplay aren’t from the US haha 🇬🇧

I was a bit sad that Coldplay wasn't mentioned at the start and only as an example at the mid/end of the video. When Coldplay had the xylobands for the first time everyone was speaking about it. It was so unique and new. Adds such an amazing new layer to the light design of the show

Well... if that's "entirely Coldplay's tech" and if Coldplay own Xyloband and has patented their technology... then it *can't* be entirely Coldplay's tech now, can it? I get the point you're trying to make, which is to point out who the "inventors" where but... I mean they're not going to sell their patents to someone else (at least I don't think so). Montreal is the city with the most festivals in the world and we are known worldwide for being top providers of anything you want in the event industry with several companies ranking very very high (Solotech being 3rd biggest event tech company in the world). What I mean is, I would be more than surprised, since Xylobadn is still very much in activity, that Pixmob is based on their patents. They (or more likely someone on their team with the name of the band being incorporated so the patent belongs to "Coldplay") wouldn't sell that tech, and no Montreal start-up would have the capital to get a patent like that. Nope, they figured that one out on their own, and it's different enough that it doesn't infringe the patent. So, not entirely Coldplay tech... I mean I really don't think so.

and they did it because of when bands used to have fans hold up lighters

what makes you feel that way?

That's why the usual "Pixel" isn't a giveaway. It's meant as a handout that is supposed to be returned.

Not sure how Bluetooth makes it for a better experience. I don't want to have to fiddle with an app for my expensive souvenir to work, and I certainly don't want it connected to thousands of other phones inter-connected into one giant hub. I don't know what kind of thing they can scan once you give them permission. Whereas the wrist band is 100% fool proof, free, doesn't distract from the concert, 100% private... I'd say for the intended purpose, I'd take the wristband any day.

@@jas_batailleI went to a twice concert and it automatically worked. No Bluetooth connection needed!

​@@jas_batailleyou aren't connected to thousands of phones, you're just receiving the Bluetooth signal. And from what they are showing, the light show is much more detailed and it sounds like they are reusable rather than used once and toss in the trash. It's a totally different experience and doesn't connect you to everyone else. I've never used either so no skin in the game, just pointing out the difference.

@@jas_bataille The lightsticks themselves have bluetooth. Some of them have an app that allows you to connect to it and customize the colors.

@@jas_bataille Recently the tech has been updated to automatically connect your lightstick to the venue's controllers, a good example is BTS. Before you had to either connect the light to your phone, or via a venue booth. Now just turning your light to bluetooth mode will automatically connect it to the controller. So now it'll work similarly to the light bands that performers and festivals use.

True ARMY Bomb is very luminouos too!

Trans Siberin Orchestra. That is all.

i use my BTS lightstick as a flashlight outside concerts 😂

I was looking for this comment 💜

Ikrrrrrr💜💜💜

I thought it was a cool video. I assume most people like myself don't know about this tech even if it is old

More than anything, making it sound like a western thing when in korea and japan had been around for decades, was annoying

@@nadie-qm8rq In the video it specifically said it started in Korea. 🤦‍♂ But this infrared version of the technology is started in the west.

ow, those were my eyes!

seems dangerous for the band and the crowd to have a bunch of lasers shining every which way

@@T3H8 No, no one was harmed.

Lol blame their label. They don’t want to pay

​@@liljohnnygogowhy blame anyone? The fans are happy to pay

while Reading the comment section, only you seemed to care about this ... how crazy.

​@@speeder172What are you talking about. Theres tons of comments about this and if the e-waste wasn't your first reaction that means you are a selfish unnaware person

@@TheTransitmtl hey mate, don't need to be like this, on my desktop, I had to scroll very low to see someone carrying about it

There is no incentive for the manufacturers to do this. So they will continue to be one time use and end up in landfills.

@@the_rzh That's what regulation is for.

The BTS lightstick does that. You buy it for about $60, Bluetooth it and use the app in your phone to enter your seat number. From there, the control booth will synchronize lights for certain songs, write messages, and turn them off when needed. It's something you keep. It's also great to use as a flashlight 😅

Sounds pretty new.

its not canadian. its quebecois company

@@blip-hn6is LOL

nope, it wouldn't work as expeccted. You've missed an edge case, which is: people can change their location during the show.

i assume they can reuse these wristbands

@@Xiefux theoretically, yes. But are they actually collected for reuse after each concert?

@@andreasotto1977 i dont know, never been to such a concert

they don't collect them at least at the concerts I've been to. it probably isn't that much e-waste because of how small the chips are but it definitely is a big waste of plastic

I went to a Coldplay concert and they were collecting after the show. They even made a cute competition by showing recycling rates of the previous shows to encourage you to recycle better than other fans.
