Using Pervasive RFID to Predict Human Behavior

A Japanese consortium called the Tagged World Project has unveiled a prototype system for using RFID tags to continually monitor and ultimately predict a user's future behavior.

The project tags every object in a given space; each tag captures data and adds it to an XML database. The user can then receive feedback through a PDA, such as "Don't forget to lock the door" if he leaves the room without touching his keys.

In many instances (such as a hospital or nursing home), such an environment would be immeasurably helpful and could save lives. But in others, it could be annoying, invasive and just downright creepy.
