Immerstar, a still evolving 25 years old VR research facility

The two platforms Immersia and Immermove offer an immersive collaborative space called ImmerStar, intended for the scientific and industrial community, for international research projects. Immersia is a 3D virtual reality platform which, thanks to its exceptional dimensions, offers an environment for experimentation, particularly in the context of real-time and multi-modal interaction (vision, sound, haptics, brain-computer interface) between humans and virtual models. Immermove is a technological platform dedicated to motion capture, extended by a virtual reality space. It enables the precise capture of rapid movements (sports for example) or of a group of people, in order to study human behavior such as crowd-movement or sport gestures. This paper presents the history of the evolution of these two joint platforms, an overview of their technical specifications, associated research projects and perspective of evolutions.
