From Saturday, Oct. 5 through Monday, Oct. 7, the Downtown and Macdonald Campuses will be open only to McGill students, employees and essential visitors. Many classes will be held online. Remote work required where possible. See Campus Public Safety website for details.

Du samedi 5 octobre au lundi 7 octobre, le campus du centre-ville et le campus Macdonald ne seront accessibles qu’aux étudiants et aux membres du personnel de l’Université McGill, ainsi qu’aux visiteurs essentiels. De nombreux cours auront lieu en ligne. Le personnel devra travailler à distance, si possible. Voir le site Web de la Direction de la protection et de la prévention pour plus de détails.

3D Motion Capture

Using an optoelectric infra-red based motion capture system (4 Vicon Vantage V5, 4 Vero2.2, 8 T10S, and 2 T40S) we are able to analyze several ice hockey related tasks without having to constrain the subjects' movement with wires and/or devices that could alter the nature of the investigated task. Small retro-reflective markers are placed on the participants which are tracked by the camera system for further kinematics analysis.

This system has been used to assess wrist shot accuracy in lab, skate push-off kinematics in lab, hockey stick handling in lab, hockey skating starts on the ice surface, and wrist/slapshots on the ice surface.

Here are a few example videos of 3D work done in lab and on ice:
