I remember seeing some celebrities in the late 00s / early 10s with IR-emitting sunglasses or accessories to flood the camera sensors of paparazzi and make it harder for photographers to get spyshots of them. Would this approach work for these camera glasses as well, simply flooding them with so much IR spectrum light that their sensors simply can't see you anymore?

One of my future ideas was to have the detection trigger turning a bunch of IR LEDs on to do just this! I've only tested it a little bit against my phone camera (with around 5 850nm LEDs), but it didn't work super well (fairly bright but not enough to be useful). It did work much better in low-light though. My guess is modern cameras have better IR-cut filters, but like I mentioned I only tested against my phone and not the Ray-bans yet.

I heard about similar hats being used during the Hong Kong protests, but most modern cameras filter out IR anyway. Reflective jackets tend to work much better; they basically turn you into an overexposed bright blob on camera.

Does anyone work on smart glasses for blind people yet? Something with blackened glass, obviously, that uses image recognition to translate visual input into text via (headphone) audio to the wearer.

That would allow for urgent warnings (approaching a street, walking towards obstacle [say, an electric scooter or a fence]), scene descriptions on request, or help finding things in the view field. There's probably a lot more you could do with this to help improve quality of life for fully blind people.

Can they detect Agency Glasses? 8)

Sorry I'm still confused. Do you have a reliable way to detect if a smart glass is recording or not? I never used smart-glasses regularly, but wouldn't it be "on" all the time if one is using it, so detecting the power-on and pairing is kinda useless?

Interesting idea. It seems to me that most things which would need to be protected from hidden cameras would be stationary and not require the operator to mount the detectors on his body, but starting with mobile constraints is often helpful. I would like to draw attention to this gem of wit, easily the best I've seen in a long time: > I think the idea behind this approach is sound (actually it's light)

Isn't the biggest mobile use case where you don't want to be secretly recorded in public? This was a big concern with the original Google Glass.

The idea of being constantly monitored by a megacorp tracking all my movements wih their swarm of cameras to feed us personalized ads is utterly dystopian indeed.

But I think the only valid way yo prevent this will be legislation though, it's not a fight individuals can win on their own.

Well, there's https://www.nii.ac.jp/userimg/press_details_20121212.pdf

I think fooling facial recognition systems and CCTV-cameras-at-night is easier than fooling professional photographers. Most photograhers' cameras have IR filters, after all. And nobody's got an LED brighter than the sun.

Have you thought about the potential eye/skin damage you would be causing with IR LEDS.
