Virtual Iraq and Virtual Afghanistan are two U.S. Army programs that help soldiers cope with post-traumatic stress disorder. The projects use exposure therapy: the soldier is guided by a therapist through a virtual reconstruction of the traumatic event via head-mounted display, directional 3D audio, vibrations and smells. The system is based on technology developed for Xbox and the combat simulation scenario Full Spectrum Warrior. Researchers are currently collecting data on treatment effectiveness and will soon start clinical trials. Story
