A Watch Smarter Than You
Computer scientists from the University of Washington (UW) have built a working prototype of a 'smart watch' that warns you if you forget your wallet or your keys when leaving home.

The system is based on RFID tags attached to your car keys or your cell phone while RFID readers are installed in your home or your office. When an object is pinged by a reader, the information is transmitted to a personal server that you carry in your pockets. If the server 'thinks' that you're missing an important object, it tells the watch to alert you. Now the team wants to add a wireless location system to the personal server to improve its decision-making process. It seems useful, but what happens if you forget the server?

This summary contains more details and references, plus a picture of a user walking through a doorway with several tagged objects and carrying the 'smart watch' system.
