Summary

Many patients wonder about the risks related to sexual activity after total hip arthroplasty (THA), but this issue remains rarely discussed between patients and surgeons. To date, the relative risk of prosthetic or bony impingement and joint instability during sexual activities after THA is unknown. Hip range of motion necessary to perform sexual positions has also never been quantified.

The goal of this study was to obtain realistic motion data for 12 common sexual positions and to evaluate relative risk of impingement and joint instability during their practice. We therefore conducted an in-vivo study with two volunteers using motion capture and magnetic resonance imaging. The data obtained were then used for computer simulations of prosthetic hip joint 3D models. Our aim was to provide surgeon or other healthcare professionals with scientifically validated information, as well as specific instructions to answer patient’s inquiries.

Summary

Contracted by Kenzan SA, we created an innovative system for presenting objects or products. The Light Tracking system allows to illuminate a moving object and to display graphical content related to the presented object.

Here, the goal was to illuminate a watch. A video tracking system was developed in order to follow the movements of the watch. The tracked position was used to generate the projection of the lighting and graphics around the watch.

This system was used for Omega’s press conferences at Baselworld 2013.

Summary

First project in partnership with the Geneva University of Art and Design (HEAD) to test the protocol for a more comprehensive research to improve the comfort of garments.

Today, the complex sensations of comfort (interaction body – clothing, suitability of fabrics, etc.) are subjectively evaluated on a static body. The goal of this project was to provide new knowledge about comfort and garment fit taking into account the body movement. The comfort sensation was objectively measured with new 3D simulation tools on animated bodies, returning numerical fitting data. Ultimately, the existing perception of comfort will be innovated.

You can see here the related research project.

Summary

3D In Motion (3DIM) is a system of capture, visualization and sonification of movements in real time. This experimental setup allows to create and control 3D graphics in real time with the entire body, as well as to generate sounds from the body motion. The user’s movements are tracked by a motion capture system (Vicon, Xsens or Kinect) and instantaneously converted into sound events and graphic content, which allows you for instance to sculpt in 3D with your body. Your movements are thus transformed into an interactive instrument while immersed in a surround sound environment.

This framework is dedicated to the scene and to real time performances. It can be used for DJ nights, dance performances or other artistic projects. The interaction can be done alone or with others.

Summary

Daniel Jaquet, a PhD student in Humanities, focused his research on the description of fights in full armor in historical documents from the 16th century. Part of his thesis work aimed at analyzing the range of possible movements while wearing such a 30 kg medieval armor. By using motion capture, he was able to get a comprehensive amount of data.

For this mocap session, the main issue was related to the reflective surface of the armor. Indeed, reflections can be perceived as markers by the camera, introducing a lot of unwanted artifacts. By tuning our MXT40S cameras’ parameters and the reconstruction settings, we were able to solve this issue and collect good data for his study.
