We’re interested in the music potential for visual recognition technology in smartphones: the ability to take pictures of things using the camera, and get related content and information. A 69p iPhone app called Tune hints at this potential. “Take a picture of anything, and get a music related to that item,” explains its App Store listing. “Take a picture of a music album cover, and Tune will start playing that album for you right on your iPhone! You can literally take a picture of anything and Tune will find you music to listen to!” It’s using Rdio’s API to provide the actual music, seemingly.
