VR is used to incrementally trigger an embodied sensory experience in PTSD patients by placing soldiers within the virtual sights, sounds, feelings, and smells of common combat scenarios in Iraq and Afghanistan. This virtual exposure therapy stimulates the original embodied experience of traumatic events for soldiers so that they can connect to specific details of their memories so that they can engage in cognitive restructuring by telling the story of their experience. Rizzo says that a key component of healing from PTSD is if the patient is able to connect to the underlying emotions of the experience while sharing the narrative of their experience, and that this can unlock a cascade of healing effects that USC has been able to measure over the years.
I had a chance to try out a demo of the VR PTSD Exposure Therapy project during a reception at USC ICT during the IEEE VR 2017 conference in Los Angeles in March, and was struck by their holistic multi-modal approach of using subwoofers, smells, and passive haptic guns.
