With funding from the U.S. military, Rizzo's team in the virtual reality lab at USC's Institute for Creative Technologies wants to prepare military recruits for mental trauma before they are ever deployed overseas. It is developing virtual re-creations based on the stories told by returning veterans.
"What we want to create is something that pulls at the hearts of people," Rizzo said. "Maybe there's a child lying there with the arms blown off, screaming and crying. Maybe your action kills an innocent civilian, or you see a guy next to you get shot in the eye with blood spurting out of his face."
At the most upsetting moment, the simulation would freeze and allow a virtual character to come out and walk the player through the situation. That character might look like a gunnery sergeant, a Buddhist monk, even a former schoolteacher - whatever helps the recruit think calmly after experiencing the virtual trauma.
