A new patent was recently discovered from Sony Ericsson that while listening to our music, your device will change the song depending on your mood. The example is based on the idea that while you hold your Smart Phone, through the camera, a picture of your face will be taken, scanned and pending on your mood, a corresponding song will play. Of course as all patents go, I wouldn’t give this a second thought for something like this could be many years out or something that may just never work.
