Those gun-show tickets you've been offering out to everyone (that nobody ever takes) can suddenly do a lot more, thanks to Advancer Technologies. It's developed an Arduino-based plug-and-play bio-feedback game controller that uses EMG (electromyography) sensors to monitor the electrical activity in your skeletal muscles and turn them into game controls. For example, a bicep twinge represents jump, a gripped fist means run forwards -- as long as you've sufficient definition for those two to be distinctive. Check out the must-see muscle action after the break, or see how it's done at the source link.
