Video games from simple arcade to massively multiplayer online game and training programs such as flight and driving simulators. Entertainment environments such as motion simulators that immerse the riders/players in a virtual digital environment enhanced by motion, visual and aural cues. Reality simulators, such as one of the Virunga Mountains in Rwanda that takes you on a trip through the jungle to meet a tribe of mountain gorillas. Or training versions such as one which simulates taking a ride through human arteries and the heart to witness the buildup of plaque and thus learn about cholesterol and health.
