Throughout the history of mankind, our heart has been used for one thing: pumping blood. Now researchers at the University of Udine in Italy have come up with a better use: making videogames more challenging. Using a pulse oxymeter sensor worn around the upper body, players can control games by moving back and forth. As you move your heart pumps faster and the game responds by increasing the difficulty. The system is meant to be used to help maintain the right level of exertion during exercise. Being physically active is great, but if you ask us, we'd rather play with the intimate controller.
