UC Davis researchers have helped develop an Internet-based virtual reality environment that simulates the hallucinations of schizophrenia patients to help medical students and residents improve their understanding of the auditory and visual hallucinations experienced by people with schizophrenia. The environment takes the form of an inpatient hospital ward, based on furnishings at UC Davis Medical Center. The team used interviews with schizophrenia patients to construct simulations of auditory and visual hallucinations. Among the various effects, the hallucinations include multiple voices, a newspaper in which the word "death" would stand out in a headline, a floor falls away, leaving the user walking on stepping stones above a bank of clouds, and a gun that appears under a cone of light, with associated voices telling the user to take the gun and commit suicide. Those interested in accessing the virtual hallucinations environment can find instructions for doing so on the Web at www.ucdmc.ucdavis.edu/ais/.
