Abstract
Methods, systems, and apparatus are described for posture detection. Orientations of a body are detected with respect to first and second axes. A movement of the body with respect to a third axis is also detected. Three-dimensional orientations of the body are determined based on the orientations and the movement. The detected posture may be used for applications such as controlling medical devices and detecting patient disorders.
