Google Goggles visual search has been available for Android phones since December. Now Google is launching a version of Goggles for iOS. It’s part of the latest Google Mobile App for iPhone. The app is available for the iPhone 3GS and iPhone 4 running iOS 4. iPod touch users need not apply.
You should be able to use Goggles as a visual search tool, which means you can use the Google Mobile app to search by text, voice, or image.
As with the Android app, the iPhone app lets you point your phone camera at certain types of objects to identify them and pull up relevant search results. Right now that works best with book covers (or bar codes), DVD covers, wine labels, artwork, or famous landmarks.
You can check out Goggles for the iPhone in action in Google’s demo video below.
