Shaped like a TV remote, the controller has been designed to be easily used by beginners and pros alike. Sensors determine the Wii Remote's position is in 3-D space, which means that racing-game steering and a tennis swing, for example, are done through movements of your hand rather than by just your thumbs. What's more, a tiny speaker built into the Wii Remote promises some interactive surround sound experiences. The controller also has a force feedback "Rumble" feature and an expansion port for use with accessories, such as the Nunchuck, which adds an analogue thumbstick and trigger buttons
