I want augmented reality and that does kind of require a camera.

I want the ability to overlay historic photos over real life so I can see in a much more immersive how things used to be.

Overlays of navigation so that paths could be highlighted. Objects I’m looking for highlighted like in a video game.

All the cool things that are context sensitive.

But I want local processing and don’t need recording or photos from my pov. My pov sucks compared to what I can get from holding a camera.
