Early versions of portions of MediSim have been demonstrated. In these configurations, pre-rendered medical animation sequences were added to the JackML motion library. NPSNet (from the Naval Postgraduate School [22]) used JackML to generate human motions involving typical combat-oriented activities, as well as specialized medical treatment animations. The participant in the exercises interacted with the environment by using the Sarcos I-Port, a VR mobility simulator.
This system was tied into a standard Distributed Interactive Simulation (DIS) network. In this way, medic treatment scenarios could be performed in an environment populated by external DIS entities (although the medical animations themselves were not rendered on standard DIS image generators). Flags needed for medical animation were stored in unused segments of standard DIS Protocol Data Units. As this system evolves, new methods of transporting this data will be developed.
