I was thinking about this just the other day. You're on your way to implementing your own real-life stealth meter! Very cool!

#42A much-needed project. Making yourself invisible to such privacy-invasive devices will be the need of the day. Of the two approaches you mentioned, blocking/jamming the specific wireless traffic would be pretty interesting, if possible.
> blocking/jamming the specific wireless traffic would be pretty interesting, if possible. And probably highly illegal.
Yeah, true. Implementing this would be tricky.

#43Does 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…
there's a lovely documentary by a blind British comedian about exactly this: https://connect.open.ac.uk/seeingintothefuture/

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…
Have you thought about the potential eye/skin damage you would be causing with IR LEDS.
Potentially as much as none, because it's UV that does the damage?

#46I 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?
I have been thinking of a device to thwart license plate readers by dumping a ton of IR and/or visible light on the plate before it gets read.
Perhaps combined with some reflective coating? Retroreflectors are promising

I guess IR can be harmful (IR lasers, military grade IR LEDs). But yes, likely not the consumer grade IR LED.

#48Interesting 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)
It's me. I want to be protected from hidden cameras from other peoples glasses.

Every time I read about smart glasses I wonder the same thing. Obviously the technology isn’t perfect, but it seems that even a basic pair of smart glasses with primitive image processing could be life-changing for a completely blind person. Yet as far as I can tell, most blind people don’t use technology at all for this purpose.
Unfortunately, the HN website is extremely unfriendly to users relying on assistive technologies (lack of ARIA tags, semantic elements etc.), otherwise there might be more blind people commenting here who could shed light on such things, no pun intended.

What about correlating transmitted wireless frames with a LED flashing pattern? If the glasses stream video with a variable bitrate codec over wireless, flashing vs. non-flashing should change bandwidth and therefore frame frequency. However, with searching over all channels this might be quite slow in practice.
