The DEMO exhibition in Palm Desert, in California has been going on this week and this little invention from Livescribe really appealed to us.

The Pulse Smart pen is one of those electronic pens that comes out and is almost immediately lumped into the same category as talking clocks and torch-pens.

Surprisingly, it seems like it might actually be useful.

Livescribe CEO describes Pulse as a new type of mobile computer that supports the four basic modes of human communication (reading, writing, speaking and listening).

He then went on to explain how the pen actually works.

"Using an embedded speaker and display for audio/visual input, and microphones and a pen for audio/visual output, Pulse advances the power and flexibility of mobile computing — it’s the missing link that now connects the paper and digital worlds."

A Livescribe spokesperson, Eric Petitt told TechNewsWorld the basics,

"The best way to think about it is that while you’re taking notes, it’s recording simultaneously everything your ears would be hearing. You can then go back and tap on words in your notes, and it will replay what was going on when you heard them — it’s basically time-stamped."

Sounds great. If only we had them when I was in school. Might have done a little better in Physics.
