Those of you who follow Imogen Heap's impressive social media outpourings, will be aware that she's had a pair of gloves made (built?) to allow her to control aspects of her performance using had and finger gestures.
She performed last Wednesday at Wired Magazine's The Future Of Music Event in London. Only recently finished, the gloves had their first outing at TEDGlobal in Edinburgh.
From a witness at the event (thanks Matt for pointing us to this video):
She had 4 radio packs on and a USB cable trailing down her leg!
Sharp wrist rotations step through a number of modes and then arm and finger positions can be used to control stuff - volume, pan, reverb send, low-pass filter, distortion, looping, sample triggering and pitched instrument playing.
