Hmm... I wonder if there's any solid way to detect a camera lens being in active focus or use. This app works by parsing Bluetooth traffic, but a person locally recording on their phone wouldn't have such a trail. Is there any reliable way to detect a camera lens reading exposed light?
Yeah: they'd be pointing the phone at you.
Yeah, but the issue is intent and actual usage. I don't want to fuck up my neck by always looking down at a 30deg angle, so I do try to view things on my phone more level with my face. I avoid pointing it directly at people, but I can't change how others would interpret that.
Presumably the sensor's data lines would be detectable, but probably more like laboratory conditions.
Perhaps a physical shutter would be a good happy medium. Put 'em on the damn cell phones, too.
Shoot, I should 3d print one for mine. I don't use my camera for much anyway, and better protection from impacts would be nice.
