Microsoft has been granted a patent for Electromyography (EMG) technology, which allows users to interact with smartphones, games consoles and other devices through muscle movements. Patent images (via Engadget) suggest that Microsoft is planning to adapt the tech into a â€Wearable Electromyography-Based Controller,â€ which will take the form of an armband. Another option is to attach sensor nodes to the arms, legs, chest and head. Technology like this could allow hardware such as Kinect to pick up on even the tiniest muscle movement. Theoretically it could even allow you to free run and turn in games, removing the need for rails. This is some pretty advanced tech that we probably wonâ€™t be seeing for a good few years, that is if it even gets past the design stage. It could seriously improve the accuracy of Kinect and open up new avenues for developers to explore. Freedom is key when removing the controller, and this could be the answer. However, a more user-friendly solution will have to be discovered along the way. Sticking sensors all over your body before you play would be a right pain.
