Virtual Reality (VR) has limitless possibilities for the creation of 3D stimuli for treating psychiatric patients . In virtual reality exposure therapy (VRET), a person is exposed to a computer-generated virtual environment with the help of a head-mounted display device, flat screen or a computer-automated room with images all around. This virtual environment provides visual, auditory, tactile, vibratory, vestibular, and olfactory stimuli to patients.
Such a system helps a person confront feared situations or locations that are difficult and unsafe to encounter in real life.
