A few months ago, I stopped at a store to search for a new phone. The place I stopped at offered a couple of dozen different models of phones with different features, and I narrowed my search down to three or four that listed features on their boxes that sounded interesting. Usually, I’ll look online before I buy something like this, but I needed a new phone, and wanted to get one quickly.
I pulled out my mobile phone in the middle of the shopping aisle, and started to search for reviews of the choices of phones in front of me. It would have been great if I could just take a picture of them, and had more information about them come up automatically, including reviews and alternative prices elsewhere so that I could compare costs as well.
A patent application from Google describes a way of using a mobile phone to take pictures of items, and sending them to the search engine to have it search through Google Product Search as well as other web sites, to find prices and reviews and other information about those items, and make a purchase online if you would like to. The images could be of a shirt that a friend is wearing, or a bicycle that you see parked on a street, or a package on a store shelf.
The search could be based upon the actual image itself, as well as words that might appear on a box for the image or other information. The information that you receive could include such things as technical specifications, nutritional value for food items, country of origin, prices from a number of vendors, and more. If the phone was GPS enabled, Google might see that I was in the middle of a specific store, and look up the online catalog of the store to show me that item and other items offered by the store.
