Abstract
A method and an apparatus for registering motion of a user tracked by heterogeneous sensors are disclosed. The method includes initializing the first sensor so that an origin of a first sensor coordinate system is adjacent to an origin of a device coordinate system, wherein the device coordinate system is a three-dimensional coordinate system with a current position of the device as the origin; and determining a calibration parameter for transforming coordinates of the plurality of feature points according to the first sensor coordinate system to coordinates according to a second sensor coordinate system, based on the position and orientation of the device in the second sensor coordinate system.
