I wrote the AI detection with copyright one :) Happy you liked it! I found out a bit after publishing that a comic called SMBC had a similar idea a few months before me, and their approach is really funny too http://www.smbc-comics.com/comic/security

Like I mentioned in the text, I haven't looked into Wi-Fi yet. The picture/video -> transfer through the app is correct, and why an alternative method for detecting actual recording is necessary, but I'd expect to see that most events like battery status updates would be over directed BLE, since the initial boot + battery status is broadcast. And likely BTC for streaming audio. I'm unfamiliar with Wi-Fi Direct specifically, are you familiar with the process of scanning for active Wi-Fi Direct services?

Sorry don't mean to demean your effort, I read the GH post and like the hacker spirit :D. It's the rest of the people in the HN comments with 0 clue.

I like my glasses and don't really agree with your goals (nor see the point of letting you know when someone's wearing them; in my city your device would be beeping constantly) so I'm not interested in helping unfortunately. But I do wish you luck, as I said I like the spirit.

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.

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?

At some point it pretty much becomes a microwave. Radiation get absorbed and turned into heat. On a small scale not very helpful or harmful. On a larger scale nice to heat your food with but not your head.

You'd have to be moving pretty fast to red-shift IR radiation into microwaves, I think.

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

Thank you! To settle a debate between me and a friend, do you think Ray-BANNED or Ban-Rays is the better name?

Ray-Banned is a good pun, but might bring you legal trouble. I’d go with Ban-Rays

But you’d agree Ray-Banned is better

Only because I’m a pun addict. Don’t take my biased opinion on board.

Ban-Rays. Ray-BANNED could be read to mean that you've been banned by Ray-Ban IMO, the opposite of what's happening.

I think Ray-BANNED is the better name, by far.

the former

Oh hey I wrote that one! Thanks for the kind words. I'm hoping it can get the creative problem solver audience of PO!/HN thinking about the challenge of media literacy education
