I was in Cologne last weekend, a city in the middle of Germany I do love for its cultural richness. Although I travel there from time to time I still feel a little bit lost without a trace of what restaurants might be worth a visit or what places would be cool.
No problem if you have a mobile device with an Android operating system in your pocket. Google Goggles from Google Labs runs on Android version 1.6+, Google's mobile operating system. If you already have e.g. a Nexus One click on the "market" button to get access to the tool.
How does Google Goggles work? - A combination between GPS data localizing your position and compass does the job. Google will deliver detailed information of the current scene, e.g. today's carte. It works with sights, artwork, labels and book covers but in a slightly different way. If you take a photo of a sight Google uses image recognition to access related information. All these examples illustrate how powerful Google's blended search already is. By the way, "blended" search is Google's search across all vertical search directories integrated into Google (books, images, video, etc.).
Imagine if face recognition and social data, which are already indexed and retrievable via Google, will be available via Google Goggles as well. Search your name in Google to get to know what the world already knows about you.
The powerful technology behind the restaurant recognition (GPS + compass data combined) will be helpful for street journalists as well. Photos taken outside can easily be linked to location. Validation of pictures will be easier if location data were added. Remember the "famous" Twitpic picture "There's a plane in the Hudson. I'm on a ferry going to pick up the people. Crazy."
