Google just officially announced that they are working on Project Glass - think of it as augmented reality heads up display glasses that works like a smartphone. This concept has been bandied about for a long time, but may be closer than we think.
I'm sure it will take a while before the mainstream legal software vendors will provide compatible software. And for those of us who have avoided glasses through contacts or laser surgery, the thought of wearing glasses again is not compelling. But the contact lens version might take a while longer.
But think of the possibilities.
Face recognition to remind us how we know that person who just said hello.
When giving presentations it could control slide advance, show us the current slide, and include our talk on a teleprompter that would automatically scroll to the speed we are speaking.
What other uses come to mind?
