Klangpong is an audible interpretation of the arcade classic “Pong”. It extends the gaming experience by enabling gaming between seeing and blind people by providing audible feedback of the game elements. The game and the menu interface do not dependend on its graphical representation and can thus be enjoyed in its an entirety with just a pair of headphones and a WiiMote.
