The Text-it Note system offers users an alternative means of sending and receiving text messages. By combining hand writing recognition software and some novel hardware, users can simply write messages directly onto conventional Post-it Notes; the message itself is then converted into text automatically, and the recipient identified with a final stroke of the pen. Incoming SMS messages can also be printed onto small paper labels, thus offering the user an entirely paper based messaging system.
