Google Goggles has become my new favorite app on Android. There is something about just taking a picture and it tells me what I want to know about it. It just came out and it isn’t perfect but it’s a great start. In no time it will be able to detect anything. I could just image if I was hiking and I could take a picture of what I think is poison ivy and Goggles will tell me if I’m right. It’s free in the Android marketplace. Just search for Goggles.
