Are you saying this doesn't do any kind of positioning? Just plays when the accelerometer shows movement and stops when it doesn't? I need to try this at some point because it really feels like that wouldn't work. People walk at different speeds so the video would desync, take a wrong turn or incorrectly recognise landmarks so the video would be completely wrong... What's the error recovery procedure here?

Might just need to try it if you say it works well. Hopefully I find some time to nuke the blockchain out of this and set up a test instance for our university.

Correct - no positioning at all. Just get the user where they want to go.

MotionAware playback. And yes! You are asking all the right questions.

Desync from the video playback is a known problem with 1st person POV nav - many different ways to tackle it. I haven't implemented them yet - right now I am focused on building a Stableframe feature that allows the creators to upload video that hasn't been recorded with a gimbal and will stabilize the frame the get rid of the vertical bounce when people walk and record routes
