The company's Multifunction Dome is the largest commercially available rear projection dome. It lets people experience almost any situation for training or entertainment purposes by immersing them in an environment that combines a Hollywood-style set and realistic props, such as functioning, simulated instruments, along with projected high-resolution images. The first dome will be in operation at Ft. Sill, Okla., in early 2010. It will be used by the U.S. Army Air Defense Artillery School for immersive training of Stinger missile crews and forward observers, as well as for mission rehearsal and other purposes.Other possible applications for the dome include training for air traffic controllers, unmanned aerial systems pilot training, as well as applications for the entertainment industry and amusement parks.
