Gravity sensor is a soft sensor, which derives value from standard accelerometer device by filtering out the acceleration which is not caused by gravity. Gravity sensor provides a three dimensional vector indicating the direction and magnitude of gravity. Typically, this sensor is used to determine the device's relative orientation in space. The units and the coordinate system is the same as the one used by the acceleration sensor. When a device is at rest, the output of the gravity sensor should be identical to that of the accelerometer. More information can be found in: http://www.usb.org/developers/hidpage/HUTRR59_-_Usages_for_Wearables.pdf Gravity sensor and accelerometer have similar channels and share channel usage ids. So the most of the code for accel_3d can be reused.
