/**
* A motion device is an input device that returns a tuple of accelerometer state vector and
* gyroscope state vector.
*
* For accelerometer state vector:
* x+ is the same direction as LEFT on D-pad.
* y+ is normal to the touch screen, pointing outward.
* z+ is the same direction as UP on D-pad.
* Units: measured in unit of gravitational acceleration
*
* For gyroscope state vector:
* x+ is the same direction as LEFT on D-pad.
* y+ is normal to the touch screen, pointing outward.
* z+ is the same direction as UP on D-pad.
* Orientation is determined by right-hand rule.
* Units: deg/sec
