Iddo Genuth writes to mention that MIT researchers have made their first pass at bringing the common yellow post-it note into the digital age. Using a combination of artificial intelligence, RFID, and ink recognition, the team hopes to make the digital version as ubiquitous as possible. "The Quickie application not only allows users to browse their notes, but also lets users search for specific information or keywords. Using a freely available commonsense knowledge engine and computational AI techniques, the software processes the written text and determines the relevant context of the notes, categorizing them appropriately. "The system uses its understanding of the user's intentions, content, and the context of the notes to provide the user with reminders, alerts, messages, and just-in-time information" - said the inventors. Additionally, each Quickie carries a unique RFID tag, so that it can be easily located around the house or office. Therefore, users can be sure never to lose a bookmarked book or any other object marked with a Quickie."
