Hobbies. You are knitting - you see AR overlay of next stitch(es). You are servicing you car - you see an overlay of the part you are dismantling. You and your mate are doing yoga - you see an overlay of how they are supposed to hold the pose. You are a watch collector, browsing potential purchases in a physical shop - you see an overlay of history and recent sale prices for the piece. You are into electronics - you can see the datasheet associated with the device you are looking at, at a glance. Or the instrument reading without looking away. And so on... Possibilities genuinely seem endless and relatively mass market.

Pre Coronovirus, a killer app might have been translation. (menus, street signs, etc). Hey ho.
