VR/AR
Summary: Research includes the development of an immersive virtual environment that simulates visual, aural and other sensory channels, and a network of sensors that captures users' responses, including motion, facial expression and various physiological signals. This system allows numerous forms of exploratory applications in psychology, neuro-science, mental health, and human factors in economics. Current exploratory applications includes: conceptual design in VR, post-stroke rehabilitation in VR, early detection of Alzheimer's, Parkinson's, mTBI (mild traumatic brain injuries), various anxieties, and dementia in VR, as well as various exposure therapies in VR.
