Amazon Remembers via iPhone

The Amazon app for the iPhone includes a pretty ingenious component called “Remembers”: Take a photo of a product that you want more info about, wait a few minutes for it to process and voila, you get the corresponding product page on Amazon.com.  It worked perfectly for the three products I tested:  a book cover, a nutrition bar and a water bottle.  It yielded the exact product result, including the Klean Kanteen Stainless Water Bottle.  It works not by advanced OCR image processing, but with the aid of an actual human being(s) processing the request and locating the result in the Amazon DB.  Amazon calls this process a, “Human Intelligence Task” and offers similar services under their beta called  Mechanical Turk.
