An accelerometer has many practical uses for applications that depend on the movements of a Windows Phone in three-dimensional space. With data from an accelerometer, you can steer a simulated car in a driving game or fly a plane in a flight simulator. Capturing a motion such as a shake, a punch, a swing, or a slash and mixing this accelerometer data with a physics engine can be used to create Wii-like games. Just for fun, you can build novelty applications to amaze your friends, such as a light saber simulation that makes Star Wars-like sounds as you swing your phone in the air. An accelerometer can even be used for business applications, like a level to use when you hang a picture frame. Under the covers, the controllers for games that run on consoles like the Wii remotes are nothing more than accelerometers wrapped in buttons and plastic.
