Google is already training its brand-new Goggles image-recognition app on advertisers, hoping the software's "visual search" capabilities prove useful in helping customers glean more information from print and outdoor ads, among other media. Five top marketers—Buick, Disney, Diageo, T-Mobile and Delta Airlines—have signed up to experiment with Goggles. Each has embedded the Goggles symbol in ads, allowing people who are running the app on Android phones to snap photos of the ads and then click through to mobile properties associated with them. Watch the video below to see how it works. The app, which is still rudimentary, certainly seems to hold promise, though of course it's a shame you don't get to wear actual goggles.
