Now your phone’s camera can help you find out more about the world around you. Google Goggles lets you search by taking pictures. Goggles is now a feature of Google Mobile App for iPhone (it was only available for androide phones before).
If you don’t like to photograph, you can also give voice commands and/or use the GPS function to find locations.
For now, the Google Goggles feature is only available in English and for iPhone 3GS and iPhone 4 devices running iOS 4 or higher. The Google Mobile app is free and available in iTunes for downloading.
In the new version of Google Mobile App just tap on the camera button to search using Goggles. Goggles will analyze the image and highlight the objects it recognizes, just click on them to find out more.
