Photo2Search: Explore the Real World via Camera Phone: “Photo2Search works like this: Seeking information about something seen, a user takes a photo of the object and sends the photo, via e-mail or Multimedia Messaging Service, to a Web-based server, which searches an image database for matches. The server then delivers database information—whether it be a Web page featuring the object in the photo or information associated with the object—to the user, who can act on the information received: read a menu, enter a gallery, book a hotel room, make a purchase.”
