I was hoping for a pen that simultaneously puts ink on the page and also tracks exactly what you write/draw and uploads it every minute or so. It'd probably be too difficult to do that with a tactile sensor, so perhaps a tiny camera could be used instead?

I assume neither of those are very practical at the moment, otherwise a company would've tried it already.

They do exist ( http://www.livescribe.com/en-us/smartpen/ ) but I have no idea if they're any good. You have to use their pen and their paper… I like my Field Notes and Lamy.
