You've heard that Google is working on computerized glasses. They're called Google Glass, and developers can already buy them. It turns out Microsoft is working on something similar. It filed some patents on the project. There's a big difference between what Microsoft is working on and Google Glass, though. The most recent word out of Google is that Google Glass isn't going to use "augmented reality" – where data and illustrations overlay the actual world around you.
