Timo Arnall had a great idea: using post its on a desk and a mobile phone to trigger specific events and actions. The idea behind the address book desk is very simple: to each Post-It on the table top, correspond a rfid tag that can be programmed with a specific trigger. Now the mobile comes to play, because when close to the tag, with a specific reader can match the will of the user to activate the specific trigger indicated on the Post-It. Very simple, yet very powerful.
