A new system is being developed that uses Electromyography (EMG) sensors attached to your muscles to let players gesture instead of using a peripheral. In plain English this means that this system will let you play games like Guitar Hero without the guitar. While the original article and video include other, more “practical” uses for this system, the implications of this for video games is… pretty cool. Playing video games without needing any controller? Soon enough we’ll be able to play video games with our minds.
