Ever seen one of those iPhone astronomy apps where you hold up the phone and it shows which stars you’re looking at (e.g. Star Walk)? That’s augmented reality. You paint useful information on top of the world. There are going to be a LOT of reality-augmenting apps on the way.
Here’s my favorite new example: an app that will turn your Prius (or whatever under-powered car you drive) into a super car. It’s called XLR8 (“accelerate”… get it?). The reviewer says “I didn’t write this app, but I hope the folks that did become wealthy beyond their wildest dreams.” All it does is give your car a new sound, but it’s responsive and realistic. Watch this video.
For comparison with something a little more, shall we say realistic and unaugmented, here’s a famous short film called C’était un Rendez-vous in which a (crazy) guy drives inadvisably fast through the streets of Paris.
