Amazon begins temperature checks and will provide surgical masks at warehouses

This sentence stuck out to me:

"The company will also use machine-learning software to monitor building cameras and determine whether employees are staying at safe distances during their shifts, or whether they are often huddled too close together"

I can see that working in tandem with some kind of alarm or alert sounding when workers are too close together. The second order effect, would be some kind of Pavlovian response in Amazon warehouse workers even beyond this physical distancing period.

That's the kind of stuff you used to read in sci-fi novels.

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.
