Google recently released something called Google Goggles that effectively allow you to use your mobile phone (equipped with camera) to take a snapshot of something (like a bar code, business card, etc) and then have it reveal additional information about it.   You can read a little bit about it here.

While it is relatively new, the immediate thing I considered was someone attaching their iphone (or similar device) to their grocery cart as they walk through the store to “capture” the prices of all the items in a grocery store.   Rinse & repeat for competitors and you suddenly have a real-time price list of items at your favorite grocery store.   It’s a combination of Google Street View and Google Goggles with price match!

To take it one step further, I’d love to compile a list of items I generally buy and have google (or some app) tell me where the cheapest place is to get those items.  The big plus is getting rid of all those flyers and circulars regarding what’s on sale where and when – it would be all instant!

Come on Google, give the public what it wants!
