In the same vein, it would be kind of cool if there was a wristband / necklace kit that vibrated aggressively if they were placed within close proximity. For example, most people touch their face between 2-3,000 times a day. The current CDC recommendation is to not touch your face, but people do this unconsciously.

So make two wrist bands, wear one on each wrist. Then also make a necklace of some kind, and if a wristband is brought within 1-2 inches of the necklace, vibrate the wristband somehow. This will alert the person that they are touching their face and after enough use, they will hopefully do it less.

I wonder if this could be done with a smartwatch alone.

Touching your face means that your hand is at a specific angle, and probably has some accelerometer and gyroscope readings that can be identified as "touching your face" vs "raising your hand" or lifting things or whatever else.

Dedicated hardware would be nice, but it's unlikely to be useful in time for the current pandemic. But an app that was like 90% accurate that could be released right now (or within a week or 2) might be able to make a difference.
