A computerised DJ that uses feedback from the dancers to generate new music
has been developed by artificial intelligence experts at Hewlett-Packard.Each clubber has a device like a wristwatch that monitors their location,
heart and perspiration rate, and movement and feeds info back to the “HPDJ”
via a wireless link.

To create a song, the HPDJ chooses tracks from a large library and then modifies and overlays them, based on this data, using a genetic algorithm to
determine which tracks survive.
