I remember reading a short story a number of years ago (2000-2008) that involved a character wearing a computer like a crown on their head. They were able to query searches and know the results, and I think I also remember there being some description of a map-like program where they were able to look down at their location from the sky and routes would appear from their location to their destination.
I've looked through similar questions posted here and didn't find anything like it. It's not "Norbert and the System". I think I remember the main character being a woman?
