A kinematic data gathering system to assess human motion in zero-g

Research was conducted to assess the feasibility of utilizing one-dimensional accelerometers mounted in an orthogonal arrangement to measure astronaut´s motion in zero-gravity environments. The initial investigation was centered on determining optimal positions, orientations, and response of the accelerometer device. Various types of accelerometers were tested to determine the most suitable device for the measurement of low-frequency human motion. A system is described that eliminates the shortcomings of video-based systems while providing a real-time graphical representation of the motion.<>
