Mixed reality simulation system

A mixed reality simulation system, comprising - a real-time motion capture system (20), including the following elements connected to one another. - at least one data processing unit (PC1, PC2), - a group of markers (22) which can be attached to the body of an active user (100) of the system, - a plurality of cameras (21) arranged such that at all times, at least two of them can capture a same marker (22), - two data gloves (30), - a graphic station (10), - a first display device (40) for said active user, and - at least one physical mock-up (60), said graphic station being configured to process the information provided by the motion capture system and data gloves, and to send said information in the form of images to the first display device in real time.
