The students have built a game. The aim of the game is to bring all the obstacles to life at the same time. Instead of joysticks and controllers, all that is needed are human instincts—twice over. Person x guides the ball to the left and right with their nose, while their partner, person y, juggles the ball in the air by clapping their hands. A camera and a microphone recognize the poses and sounds of both players. After a short lifetime, the animations lose energy and return to hibernation. The more advanced the level, the faster this happens. Only together and with good coordination will you be successful.
