Technologies are described herein for providing enhanced motion tracking using a transportable inertial sensor. Configurations disclosed herein utilize a first inertial sensor mounted to a device to determine a frame of reference, and a second inertial sensor mounted to an object to determine movement of the object within the frame of reference. Configurations disclosed herein determine if the frame of reference is established. If it is determined that the frame of reference is established, the first inertial sensor and the second inertial sensor are used to detect movement of the object within the frame of reference.
