I've written a bunch more on the link (+photos are there), but essentially this uses 2 fingerprinting approaches: - retro-reflectivity of the camera sensor by looking at IR reflections. mixed results here. - wireless traffic (primarily BLE, also looking into BTC and wifi)
For the latter, I'm currently just using an ESP32, and I can consistently detect when the Meta Raybans are 1) pairing, 2) first powered on, 3) (less consistently) when they're taken out of the charging case. When they do detect something, it plays a little jingle next to your ear.
Ideally I want to be able to detect them when they're in use, and not just at boot. I've come across the nRF52840, which seems like it can follow directed BLE traffic beyond the initial broadcast, but from my understanding it would still need to catch the first CONNECT_REQ event regardless. On the bluetooth classic side of things, all the hardware looks really expensive! Any ideas are appreciated. Thanks!
I would like to draw attention to this gem of wit, easily the best I've seen in a long time:

Not a creep here and use my Meta glasses to record my normal non-creepy life and life experiences. They are really convenient and useful (just suck cause they break easily either from software updates to water splashes)!
It teaches people to trust "Currently NonEvil Company™" to do the good thing.
First, and obvious problem is that this "trains" us to rely on brands to protect us. And to keep doing this. Companies may have different interests than their consumers. Ideally and sometimes these interests are aligned. But nothing guarantees this remains so. Companies will "Become evil", if only because they are sometimes legally forced to by governments or shareholders.
Second, is that this teaches people not to be responsible but to leave that to companies or technology. Which works if e.g. Apple and Meta are the only providers. But falls apart the moment Focebook glasses, Apelle Gear or Rang Doorbell is available on temu. And becomes worse when HP, Dell, Samsung, IBM and other legitimate producers start competing in the space. We've now been trained that what the first companies did was "The Good Thing", but lack the social structure, laws, or even common sense to manage a world in which this self-constraint of the companies no longer applies.
Overall why are we not up in arms about all the video cameras that record in all cities everyday which companies like Clearview and others have our public images in their databases yet we are up in arms about smart glasses?
THis is a solution to this public debate and Apple hasnt released their glasses yet and they are a privacy company and heavily market themselves as such. As the poster notes smart glasses adoption is rising and will only continue to do so... so this debate in time will continue to fade into the background as there is no same amount of debate about all the cameras in cities that are already recording us. With that in mind the smart glass privacy debate is an odd one to me where corporations are already recording us in these same public places.
Reminds me of my 24 year old niece in which her and her friends hate chatGPT/AI. Hippies fighting technological progress futilely. Like the iPhone haters of 2007 to 2010!
