This post isn’t about anything new, but I get asked about this every time I use it so I thought I would write about it. For the past two years I’ve been using the excellent Livescribe Echo recording pen to record my class lectures. I’m a painfully slow writer and I often just can’t keep up with what professor is saying as I furiously try to take notes. The Livescribe Echo has allowed me to take far fewer notes and concentrate to a much greater degree on what is being said in class. It does this by recording every pen stroke I make on paper, as well as capturing every sound that is made as I write. After class, I can transfer the recording to my PC and watch myself taking notes as I listen to the lecture at the same time. I can skip ahead to any point, or even play it back at 2x speed (yes people will sound like Alvin and the Chipmunks if you do the latter).
How does it accomplish this voodoo?
