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.
Google Glass is actually just a tiny screen you have to look up and to the left to see.
Microsoft's glasses seem to utilize augmented reality. In a patent illustration we've embedded below, you can see that the glasses put data on top of a live action concert and a ballgame.
Both gadget concepts are very interesting.
Lots of people disagree with me, including other BI writers, but I think something like Google Glass or whatever Microsoft is working on could end up replacing the smartphone as the dominant way people access the Internet and connect to each other.
