google goggles

Google Goggles (free) is an ambitious Augmented Reality (AR) app that uses your Android smartphone camera as input, then tries to match the captured image with relevant search results. When you see something interesting, such as a restaurant or a landmark, and decide you want to know more about it, you can whip out your Android phone and snap a picture. Google Googles then goes to work to serve up information about the restaurant or landmark--often, however, with very mixed results. But when it is used properly, Goggles can be quite useful.
