AUDIO AND OBJECT RECOGNITION: With a new Firefly feature, snap a photo of a book, and it'll show you where to buy it. Listen to a song playing in the background, and it'll direct you to that tune on Amazon. It can even direct you to knowledge, such as pulling up a Wikipedia entry on a painting you snapped. The feature will also let you snap bar codes, email addresses, phone numbers and more.
This concept isn't entirely new. Sony, for instance, has a tool for getting information over the Internet by snapping a bar code or a landmark. Firefly goes further, though, by incorporating audio recognition. (Source: AP)
