The “Soundtrack Jacket” plays music that corresponds with your mood and biological signals. It can either play it outloud over built-in speakers or pump tunes into a headset.
It has a neural net training mode that senses your bio-metrics in response to musical inputs. This maps certain musical tempos, genres, timbres, instruments, etc. to heart rate, skin voltage, body temperature, chemical concentrations, etc. Then you can use the neural net to detect bio-metric patterns and play music that fits your mood. The songs could be selected from a playlist (perhaps from the music genome project - see www.pandora.com) or maybe even generated real-time from tracks and samples.
