In general, systems based on radar are trying to replace wearables for sleep states tracking, elderly fall detection etc. But I'm not sure yet what other applications it might have. The ability to track my location just seemed like a good first step.
Cons: Wearing Hololens all day, spending thousands on a hobby project. :-/ Fascinating if you manage to borrow one though.
Even more fascinating, if they manage to wear it the whole day.
Tracking accuracy can sometimes drift quite a bit with this if you’re not careful, but it can perform pretty well, especially if loop closing is enabled.
Interesting approach using radar for tracking, if you make any progress would be interested to hear about it.
