Hey, nice to see museum folks here!

I previously worked for a museum too, trying to solve the same problem.

Many of the providers called it "blue dot" positioning/wayfinding, and aside from Bluetooth, vendors also offered ultrasonic beacons (your phone can hear and triangulate), wifi triangulation (you map out various APs across the property into a 3d map and the app then triangulate). I think there were also some that would try to guess your location based on the music playing in the background (like if your exhibit had a background track) and another that did something similar with visible light.

One of the more interesting techs I saw was a image recognition network of ceiling cameras, mounted on lighting rails, that was supposed to keep track of individual visitors as they moved about each exhibit. I wasn't sure if it could track them through the whole facility (as opposed to just one discrete room), but if so, that'd be interesting (and creepy).

Edit: PS you might wanna check out the MCN (Museum Computer Network) conference and mailing list for museum technologists.

At the end of the day all of them were too complex and/or expensive. We just printed out a bunch of "you are here" signs with QR codes that led to specific webpages and/or anchors on our digital map. Like /exhibits/blah or /map#blah. The signs showed a cutout of their current map position, so when they scanned the QR code, it would look like the same section of the map.

This was at the tail end of covid, though, and management was still against paper maps at that point. I really wish we could've just printed those out.

IMO only (we wanted to do more research and A/B tests, but I don't think we got to it): the UX of trying to navigate a big 3d indoor space on a tiny phone screen is not great. It's hard to represent both floors (and their corresponding stairs/elevators) and relative facing (NSEW is totally unclear indoors). Pathfinding / navigation from point A to B was also something we didn't solve yet, because it's hard to see the whole path when you're zoomed in, hard to see geometry when you're zoomed out. Overall a bigger paper map in a trifold was a lot simpler.

Thanks so much for sharing your experience. I'm thinking less about mapping (at least, not 'live' mapping) and more about proximity to key exhibits (ie the app says 'hey, you're near X painting' and jumps to the info on that piece. Some of the technical solutions you outline are really interesting (background music!). It may all come to nothing but I'm enjoying investigating and talking to other museum people :)
Cool! I think that becomes more doable then, when the app just has to be able to distinguish between one of several possibilities (one out of X exhibits) instead of anywhere on the museum campus.

I think the ultrasonic beacons might work better than Bluetooth for this, and have less issues with wall/floor penetration. It's probably easier to ask visitors "our exhibits play a special sound signal to let the app know when you're close. Will you allow mic access?" than to try to explain how BT beacons work. Whatever you choose though, it's probably best to back it up with a QR code or just a printed number ("Which exhibit are you at?" 27) etc.
