Google offers search by sight
Google's first search engine let people search by typing text onto a Web page. Next came queries spoken over the phone.
On Monday, Google announced the ability to perform an Internet search by submitting a photograph. The experimental search-by-sight feature, called Google Goggles, has a database of billions of images that informs its analysis of what's been uploaded, said Vic Gundotra, Google's vice president of engineering. It can recognize books, album covers, artwork, landmarks, places, logos, and more.
"It is our goal to be able to identify any image," he said. "It represents our earliest efforts in the field of computer vision. You can take a picture of an item, use that picture of whatever you take as the query."L33tdawg: So what happens when you submit a picture of a single quotation mark? :P
