A novel system has been developed at the University of Maryland Space System Laboratory with the goal of providing the researcher with a new view of the human inside a space suit. Based on an array of microprocessors and microelectromechanical (MEMS) inertial measurement units (IMUs), the system allows monitoring of the kinematics of the suit occupant in an unobtrusive, light weight and compact fashion, without requiring any external equipment such as would be necessary with video-based motion tracking. The instrumented system is composed mainly of three blocks: the acquisition system, the receiver element, and the recording and visualization software. It includes seven microprocessors that acquire accelerations, angular rates and magnetic eld measurements from 18 dierent |
