Imagine a pen that remembers everything it writes, and records everything it hears. Plug it into your computer and it regenerates page after page of your handwritten notes. Click on a word in those notes and you hear what was said, sung or played when the pen initially touched paper. That’s the experience of the Livescribe. The USB-dockable device looks like the lovechild of a Waterman and a Cuban cigar — a fattish writing implement, but not thick enough to be uncomfortable or overly dorky. The barrel contains an excellent microphone and speaker combo, up to 4G (400 audio hours) of flash memory, and an infrared camera that looks out onto your writing through a lens under pen’s shortened ink cartridge. That lens, and the Livescribe’s brain, decode tiny dot patterns on special Anoto paper that is required for the Livescribe to work its magic. (Notebooks cost about the same as Moleskines.) As the pen records audio it also captures the dot-encoded addresses of all the points on the page it passes over. The result is a mediamaker’s dream — a flawless, synched capture of notes and audio. And, everything you record can be uploaded to the Livescribe website so you can share your notes, animated and with sound. If Harry Potter were a reporter, this would be his gear.
