This document discusses motion sensors and their applications. It notes that combinations of accelerometers, gyroscopes, magnetometers, and pressure sensors can provide up to 10 degrees of freedom for precise motion detection. It describes how these sensors detect linear and angular motion. The document also outlines an application framework for handling data from different motion sensor devices and situations, and lists some potential applications like controls, games, and navigation.

2.  Accelerometer + Gyroscope + Magnetometer (+
Pressure Sensor)
 Up to 10 D(oF, Degree of Freedom) of
combinations for more precision
 Accelerometer: Detects Linear Motion in 3 Axis
 Gyroscope: Detects Angular Motion in Axis
 Magnetometer: Same as Gyroscope, less
precise/less expensive
 Application Framework needed to handle
versatile situations/devices
