7. Google Goggles, 2009
At its search event in December 2009, Google unveiled its foray into visual search with a product called Google Goggles. Goggles, which today is still in beta, is a downloadable image- recognition application for mobile devices.
If you use the app to take a picture of a famous landmark, for example, Goggles will search for more information about it. If you use it to scan a barcode, and it will search for information on the project.
