A group of Japanese scientists have invented an electronic device that stimulates the muscles on the forearm to move the fingers in time with ones favourite guitar solo.
The invention, called PosessedHand, can be programmed to move your fingers in time with the tunes without your brain needing to think about it.
Using a belt worn around the forearm, the machine contains 28 electrodes, which flex each of the joints in your fingers and thumb as well as producing two wrist movements.
While the device could be used for wannabe musicians, it is also hoped that the technology may be able to help rehabilitate people who have suffered strokes.
Emi Tamaki and a team at the University of Tokyo, using the Koto, a Japanese stringed instrument, undertook the development of the device.
Players wear plectrums on three fingers to pluck the instrument’s strings, while the music score indicates which fingers should be moved.
The scientists programmed PossessedHand to stimulate the wearer’s hand to play a tune on the instrument.
“The user’s fingers are controlled without the user’s mind,” the Daily Mail quoted Tamaki as telling New Scientist.
But Simon Holland, director of music computing the Open University was sceptical of the device, saying there is a big difference between learning to play one song using this method and being a competent musician.
“You might learn a fingering technique and be able to reproduced that, without being able to perform simple variants,” he added.
