Immersive real-time multi-user interaction with computer simulated pedestrians during emergencies
… fire, smoke and toxic products. Interactive virtual training environments (VTE) with validated pedestrian dynamics are non-existent in firefighting and law enforcement training. Human behaviour is often made to appear real in VTEs rather than qualitatively correct and direct interaction with …
