Reminds me of a UX course I took many years ago at uni.

As an exercise, we were asked to come up with a solution to help people navigate campus. There were so many suggestions for apps or interactive touch screens. Someone suggested installing terminals where you type where you want to go, and then the floor lights up with directions. Someone else did the same, only it would launch a drone for you to follow.

I suggested hanging printed paper maps on the walls with "you are here" stickers.
