The anonymous source included an illustration showing how this rumored new feature would work. The user will use his/her finger to outline on the screen, the object that information is requested for. In the example sent by the source, a coffee mug and a tape dispenser are pictured. The mug is outlined by a finger while the other object is left alone. The Google Camera app comes back with information about the outlined object, in this case the mug, and reveals a store where it can be purchased from, and a price. And the outlining can be done in real-time before a picture is snapped, or after a photo has been taken.
Until this new feature is ready for prime time, you can still download and install the Google Goggles app on your Android phone.
