I made an app.

Nearby Glasses is here to warn you when smart glasses are nearby.

I hope it's useful for someone.

The app is now open source (AGPL-3.0), the app is free and rather simple
https://github.com/yjeanrenaud/yj_nearbyglasses

It's also downloadable outside the Play Store. iOS port is in the making. F-Droid is an option, will have to look into that

@yjeanrenaud Now we need an app to Jam them or make them stop working altogether.
@Pamela1960 @yjeanrenaud let's not forget that these devices could be very useful, maybe even life-changing for people with impaired sight, and possibly other disabilities too?
@stine @Pamela1960 absolutely. I impose to people abusing it, for abusing people
@stine @Pamela1960 @yjeanrenaud some of us have had multiple concussions and dream of having devices that would just remind us what people's names are in public, and maybe when we last interacted. Sigh.
@mikebabcock @stine @Pamela1960 maybe. But at what cost?
@yjeanrenaud @stine @Pamela1960 there's no cost. You already have no expectation of privacy in public. You're on every dash camera driving by, red light cameras, security cameras, mostly connected to the Internet with very little security.
