I won’t even attempt to describe how this works scientifically, but I’ll dumb it down for you a-la-Britt version: **AHEM** So, you hook these sensors up to four different muscles. Each sensor is designated an action. In this case, the right forearm is linked to jumping, the left is linked to running, etc.
You may find yourself asking: what does this mean?
It means that it is possible to play Super Mario with your buttcheeks. That is exactly what this means.
But for now, watch a dude play with his arms. <3.
