Google has today launched Goggles, a visual search app for Android phones. Instead of using words, you can take a picture of an object with your camera phone: Google attempts to recognize the object, and return relevant search results. Goggles also provides information about businesses near you by displaying their names directly in the camera preview.
For example you can take a picture of a landmark (The Eifeltower for example) and Google will give you information about it. This can also be done for works of art, or in another example, bottles of wine. This way you do not have to describe it in words and do the search directly with a picture.
Google Goggles lets you use pictures taken with your mobile phone to search the web. There’s no need to type or speak your query – all you have to do is open the app, snap a picture, and wait for your search results.
Google Goggles works better with certain types of queries. Try taking pictures of books & DVDs, landmarks, logos, contact info, artwork, businesses, products, barcodes, or text. Currently, it’s not so good when taking pictures of animals, plants, cars, furniture, or apparel.
For the best results when taking pictures, hold your phone in “left landscape” mode, as shown below, and press the on-screen shutter button with your right thumb. via Overview : Google Goggles (Labs) – Mobile Help.
