I was sitting down chatting with my Aunt and Uncle over the weekend and they were asking about features of the Android phone I'm using -- and I had recently loaded google goggles -- and hadn't tried it.
Sitting in front of me is a picture on the wall. My Aunt says something like "That picture is so old, it probably won't recognize it."
Well, conversely, that's not exactly the case -- stuff that's been around a lot, it did really well on. It instantly recognized (and brought up several links related to) a Norman Rockwell painting on a nearby calendar. It recognized a DVD I had brought over to watch with them. It was darn impressive, actually.
If you have a 'droid -- you need to try this thing. It's supposed to someday recognize plants from their leaves, and is supposed to recognize bar-code (it failed, unfortunately, at that task ever time I tried it).
Entertaining at least! Give it a whirl:
