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: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
