You may have come across the notion of shooting a picture of a visual bar-code like object which in turn triggers a web page or some other action. I'm thinking here of something like a QR Code.
Well, Nokia is about to offer something similar, but without the code. Which is a great idea, since who really wants a world with QR tags stuck all over it?
As revealed at their current The Way We Live Next convening, it's in the 
works.
Nokia's Point & Find lets people point a camera phone at an object or picture and find out more about it or buy it just by clicking once when its name comes up on the screen.
It works by linking a set of image properties with a URL for information about what's in the image. When a user points the phone's camera at something, the system compares what the viewfinder sees with sets of image properties in a database. Also taking into consideration the user's location, it then delivers useful information about what the user is looking at.
For example, pointing the phone at a movie poster and pressing a key could make a page pop up that offers an ad for the movie and a way to buy a ticket at the theater nearest the user.
Pointing the phone at the street might bring up a contact page for a local cab company. The system could give retailers, transit agencies, manufacturers, and others the chance to reach consumers while making it easier and more intuitive for consumers to find things.“ [Pondering Primate]
