I would miss the tactility of playing with Lego or whatever.
Identifying people's faces (and buildings and streets and stuff) is a more practical application.
Kinda meh.
Walking down the streets of Sydney,
Face identify: GH ID: Rowdy
Description: Clack Fiend
I think Id'ing with glasses is too privacy invading honestly, although it would make me feel safer if you would know past criminal records but it's dangerous
Clack Fiend? With only two?!?
But considering how many hundreds if not thousands of people would pass in front of the glasses every day - what fraction of a percent would you actually recognise?
Unless there was a database of everyone's faces, and the glasses were fast enough to scan the entire database for every face.
Buildings and streets is easier - GPS location + orientation of glasses = street + building.
