Jeremiah Wander likes to use the online running game known as QWOP as an analogy for his research.
In QWOP, you control an athlete using the Q, W, O and P keys on a keyboard to move a man’s calves and thighs. The game is incredibly challenging; when most people run or walk, it just happens without thinking about it.
Wander studies signals that people don’t normally control, with the aim to use those signals to eventually create an action, like making a hand move.
