Friday, October 08, 2004From Smart Cards to Smart Objects( Via Roland Piquepaille.) A rfid based prototype of a smart watch that can warn you if you forget your wallet or your keys when leaving home has been built at university of washington.In the not-so-distant future, your wristwatch could stop you if you try to run out the door without the necessities you need for the day, like your keys, wallet or cell phone. At work,it could prompt you for important items needed for a meeting or a business lunch. In an academic setting, it could remind students which books to take as they hurry out the door for class. Think of it as a technological string around the finger – one that's smart enough to take the initiative to save you from the inconvenience and embarrassment of forgotten essentials.Such integrated, responsive systems are the next logical step in computing.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. The complete paper titled, "Reminding about tagged objects using passive RFID's" is available here. The coming explosion of RFID usage would not be centered only on big impact supply chain issues, but also on smaller utility application needs such as this. | |
