Abstract: The subject invention provides mixed simulator systems that combine the advantages of both physical objects/simulations and virtual representations. In-context integration of virtual representations with physical simulations or objects can facilitate education and training. Two modes of mixed simulation are provided. In the first mode, a virtual representation is combined with a physical simulation or object by using a tracked display capable of displaying an appropriate dynamic virtual representation as a user moves around the physical simulation or object. In the second mode, a virtual representation is combined with a physical simulation or object by projecting the virtual representation directly onto the physical object or simulation. In further embodiments, user action and interaction can be tracked and incorporated within the mixed simulator system to provide a mixed reality after-action review.
