Whilst attending a session at University last week I was shown the Pulse Smart Pen which I thought was amazing. The pen records your writing or drawing on a special notebook using an infrared camera positioned just below the nib. It also records audio at the same time and can play it back. You can upload the files to the computer and share it with others.
I thought about getting one to record meeting notes or interview notes or teacher review notes amongst other uses. I think the thing that impressed me was the fact that we are just starting with the possible applications here. If you want another opinion new york times review .
