The idea is definitely cool (and important/impactful at this time if successful). That said, in the midst of a global pandemic where human density is inherently dangerous and social distancing is espoused, naming a product "Safe by Density" gives the exact opposite initial reaction you're probably hoping for.

Yeah. Should have been "Safe by reducing Density"

"Safe from Density"

I think it could work. Heavens know, I will now have to actively avoid places that are not at least careful about how they reopen. I am mildly concerned about people, who see doing the opposite as a political expression, but some things cannot be helped.

The bet is that by giving data back to people to let them make their own decisions about safety, they'll self moderate.

Except for the workers, paid predominantly minimum wage or near it, who effectively have no choice.

A phone app could replace this right? Using the front facing camera you could run some image recognition to count the flow of people and show the statistics on screen. Put the phone on a stand and leave it running. Much cheaper.

Frankly this is an idiotic idea. In a nice cafe or lobby you’re going to have a phone on a stand with a USB cord leading to a wall wart with a readout on a 5 inch screen telling people it’s safe to go in?

Earlier quoted context omitted.

Actually, many deployments are going into factories, fulfillment centers, and meat processing plants specifically to help keep workers safe.

Viruses don't care about how many people are in a room, and this doesn't seem like something people are going to worry about much 10 years down the road.

They do "care".

First of all, if that number is in the interval [0,1], it's a qualitatively different situation than if the number is in [2,∞].

Jokes aside, there is a statistical relationship between the number of people in a room and the distance they can/will keep from each other. More density means more close encounters on average. Less density doesn't guarantee nobody gets too close to someone else, but it makes it less likely.

Having seen the way people 'queue' when waiting outside an eatery implementing social distancing guidelines - this only solves part of the problem.

Edit: Perhaps integrating it with some sort of QR Code based ticketing system for entry would alleviate the issues of people queueing (or huddling) outside the store?

You're right. "Notify me when it's quiet" is a thing the system supports. In related news, load balancing humans is a two-sided thing.

Good example of this is in elevators. People fill the available space like water.

At the same time, I'd much rather shop in a small neighborhood grocery store with 5-10 other patrons instead of 200. Trader Joe's and other retailers (at least in the bay area) have to delegate a full-time employee to the front door to throttle incoming patrons. This would free up that employee.

There are grocers who have required all corporate employees to work at least 3 days a week in a store bagging groceries, cleaning carts, and managing lines. Side not, essential businesses are the only real experts in safety right now. Everyone WFH is just guessing.
