Abstract
Methods and apparatus for capturing motion from a self-tracking device are disclosed. In embodiments, a device self-tracks motion of the device relative to a first reference frame while recording motion of a subject relative to a second reference frame, the second reference frame being a reference frame relative to the device. In the embodiments, the subject may be a real object or, alternately, the subject may be a virtual subject and a motion of the virtual object may be recorded relative to the second reference frame by associating a position offset relative to the device with the position of the virtual object in the recorded motion. The motion of the subject relative to the first reference frame may be determined from the tracked motion of the device relative to the first frame and the recorded motion of the subject relative to the second reference frame.
