Play the guitar with your feet

Japanese students are developing a machine that lets you pluck guitar strings with your foot.
The technology could one day help people who only have one arm play guitar. Playing guitar requires lots of dexterity. Instead of plucking strings with your hand, you use a foot pedal with six switches on it, each switch corresponds to a string on the guitar. The pedal is connected to a big mechanism attached to the guitar, which has six hammers on it. When you hit a switch with your foot, the hammer plucks a string.
