Microsoft has applied to patent a free-space gesture controller for a MIDI
interface that could see you kicking out jams on invisible instruments.
Using a Kinect-style depth camera, individual movements would be mapped
to notes and played out by the games console observing the action. The company actually teased a similar function in its Kinect Effect
advert, where it showed cellists, violinists and pianists all miming in
front of the sensor, although we doubt the technology is at a
sufficiently capable stage just yet. If granted, it means we could see
plenty of intentional arm-waving in future music games, or an even more
outrageous stage show from the world's most beloved Gallicsynth maven.
