Football research. Researcher conducting a virtual reality football experiment in a sports laboratory. The screen at lower right, and the virtual reality room in the background, show a football heading towards a goal, and being saved by a sportsman wearing virtual reality goggles. This set-up allows the researcher to study the sportsman's performance and reaction times. This research is being carried out in the Movement and Perception laboratory, as part of work by the French National Centre for Scientific Research (CNRS) and the University of the Mediterranean.
