I tried out Google’s new Goggles app. Basically it lets you use the camera on an Android phone to do an image-based search. The examples include landmarks, book covers, artwork, logos, contact info, and places.
So I played with it for a bit at home tonight. It’s good at picking out book covers and logos, if you’ve got good lighting and a clear image. 50-50 at landmarks, at least when taking pictures of my monitor. In a couple of cases, it actually picked out the exact photo as a match. It’s not so good at objects, even obvious ones like a Coke can. I’ll have to try it out in the real world next.
