Microsoft are developing technology that will allow people to perform "everyday tasks" - like playing Guitar Hero - by using their muscles, and not their hands.
The tech works by reading your body's electrical activity (the signals sent from your brain to your limbs) and intercepting the data, replicating the action in a program.
Potential uses for this tech include increased accessibility for those with disabilities and...lazy men with their hands full.
The above clip shows how it works, and also shows how Activision and Harmonix might be able to get around the cost and inconvenience of bulky plastic instruments by pitching future band games to the air guitar crowd.
