Abstract
Briefly, in accordance with one or more embodiments, a kinematic sensor may be carried by or on one or more body segments of a user to obtain one or more kinematic variables based at least in part on movement of the user with respect to a fixed, global reference system. The kinematic sensor comprises a tri-axial accelerometer sensor, a gyroscope sensor, and a magnetometer sensor to define the global reference system and to obtain kinematic data. The kinematic data may be transmitted via a wireless link to a remote information handling system or device, for example to monitor a health status of the user based at least in part on movement of the user with respect to the fixed, global reference system.
