Every office, university campus, events venue, hotel, airport, warehouse, factory — basically everywhere indoors have some need to navigate people around, provide relevant information, and improve efficiency.

You'd think they would add this information to openstreetmap then or at least put a map on their website (and put it in the public domain so others like OSM can add it to their maps). Or put it in the store so people can take a picture. I go into target and there are posters saying to install an app for maps. Put the map on the poster!

> and they could pop up relevant promotions along the way

Oh, right, they don't want to provide information. They want to track people and spam them.

Why do you need a human to do the initial mapping ? why can't you use a Roomba or a smaller hardware for this task

It's been said in one of the comments that the initial mapping by a human takes like 2-3 hours. Knowing the speed of a Roomba, I guess that it would take much more time to do it. And 'humans' are COTS devices available on any department store (sorry ;P).

How does your system handle the massive variance in sensor quality (accelerometer, gyro, WiFi radio) between a high-end iPhone and a budget Android device? Does the 1m accuracy hold up across the board, or does it degrade gracefully? Getting this right seems critical for scaling to a 'billion people'

All of the videos shown on the speed-run of our technology is on 4 year-old Android devices, such as Samsung S21, Pixel 6 etc.. We always test and gather statistics on older devices to fairly represent what's available, rather than latest-and-greatest.

So, devices that were top of the line a few years ago. But what about budget devices? in the 100-200 range new? I remember my old xiaomi started literally running in circles as the phone heated up 10-15 minutes after starting navigation: If i stood still the position would move in a circle of a few meters of radius.

Incidentally, the devices you metion are what i also use to develop, because those line of products actually behave as they should, per documentation. But most bugs and crashes always come from budget and no name devices because both the hardware and firmware is crap

Honestly, I've wanted a system for a while where shops can provide a map, and I can search for an item and it will show me where in the shop that item is. I don't think I've ever been in a shop big enough where I'd need satnav to tell me how to get there though, is that an American thing?

I was with them until they said that it's going to give me ads while I'm walking around

The dream of augmented reality was brilliant until the obvious consequences were recognized

Interestingly, a version of this technology was built by a government contractor some years ago, because they too wanted to track people indoors. I don't think it used a smartphone though...

I think an acquisition would be unfortunate. This could become really huge / useful to the world without being locked up as a private company's IP. Personally I would license it rather than sell it, as well as offering offline apps and limited SaaS. You don't need an established enterprise to sell it commercially; you just need a sexy product and some industry vets with contacts. If you do end up going that way, and need someone in IT Ops / DevOps / SysEng stuff to work on the "going enterprise with a billion users", give me a shout.
