Windows8 gravity acceleration sensing

The accelerometer demonstrates the use of windows. devices. sensors. The API of the accelerometer. This simple allows users to browse the accelerated army along X-, Y-, and a 3-axis Z-axes accelerometer. You can choose one of the three scenarios: • Events of accelerometer data • Events of accelerometer shake • Read acclerometer Data Events of the existing accelerometer when you choose to enable choice of Button accelerometer data items, apply Program Starts the Flow Acceleration Sensor reading in real time. Accelerometer shake event when you choose to make the button accelerometer shake event option, this application shows the cumulative number of Vibrations for each event to occur. (This application first increases the event count and then makes the most recent value .) Existing accelerometer read when you choose to make the button for the current accelerometer read option, this application will resume reading of the latest accelerometer.
