Ski Faster with Camera-less Fusion Motion Capture

01.07.2008
Professional skiers can now learn how to ski faster with the aid of a new system used to capture 3D motion of athletic movements – Fusion Motion Capture (FMC). Featured in Wiley-Blackwell’s journal, Sports Technology, this is the first time the study of FMC has been published in a journal.

This pilot study “Fusion Motion Capture: a Prototype System using Inertial Measurement Units and GPS for the Biomechanical Analysis of Ski Racing” uses FMC to capture 3D kinetics and kinematics of alpine ski racing and shows how this new technology can overcome the technological difficulties associated with athlete performance monitoring in an alpine environment.

FMC is a system which uses small sensors attached to the athlete’s limbs, helmet and soles to generate raw data from the athlete’s movement. The numbers are then crunched with the aid of a computer to reproduce accurate estimates of the position, velocity and acceleration of the athlete’s limb segments.

Lead author, Matthew Brodie, Massey University, says “With FMC, it is possible to capture motion and dynamics of alpine ski racing throughout the ski run while maintaining high resolution. This is the first time full body motion of an athlete skiing an entire course can be captured with results returned as soon as the run is completed.”

FMC is developed to capture motion in large spaces which is impractical for video motion capture. While video analysis requires several weeks to measure only a few turns, FMC is able to collect and analyze several hundred turns in a single day.

Mr. Brodie adds. “FMC enabled biomechanical analysis which provides insights into how technique, race strategy and equipment changes can increase the athlete’s speed. It is now possible to measure how ski friction, wind drag, gravity and ground reaction forces affect performance and see how variability in technique is beneficial to race time.”

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
