High Tech Slalom Ski Training

A new motion capture system using a network of sensors to detect high speed movement can help skiers to improve their downhill slalom racing techniques

clipped from technology.newscientist.com Sensors provide motion capture without the cameras The precise twists and turns of a skier's body during a downhill run have been captured for the first time by fusing the data from a multitude of body-worn sensors. The information could help skiers hone their technique before important competitions. clipped from www.youtube.com Body sensors capture a skier's twists and turns clipped from www3.interscience.wiley.com Research Article Fusion motion capture: a prototype system using inertial measurement units and GPS for the biomechanical analysis of ski racing Matthew Brodie 1 *, Alan Walmsley 1, Wyatt Page 2 Block diagram of the fusion integration algorithm for IMU and GPS measurements.
