Google has launched a new version of Google Goggles for Android, which will let you you know when you take pictures that Goggles can actually recognize.
"With this new opt-in feature in Goggles, you can simply photograph an image using your phone’s camera, and Goggles will work in the background to analyze your image," explains software engineer Pavel Vodenski. "If your photo contains items that Goggles can recognize, the app will notify you."
"Photos you take with your phone’s camera will only be seen by Goggles if you enable the Search from Camera feature," adds Vodenski.
To do this, simply launch Goggle Goggles, go to settings under menu and enable it.
No word on when the feature might come to other devices, such as the iPhone. Kind of like the Instant Upload feature of Google+.
It's version 1.6, and is available in the Android Market.
