<unk>  <unk>  uses specially programmed computers, visual immersion devices and artificially created environments to give the patient a simulated experience that can be used to diagnose and treat psychological conditions that cause difficulties for patients. In many environmental phobias, reaction to the perceived hazards, such as heights, speaking in public, flying, close spaces, are usually triggered by visual and auditory stimuli. In VR-based therapies, the<unk>  world is a means of providing artificial, controlled stimuli in the context of treatment, and with a therapist able to monitor the patient's reaction. Unlike traditional cognitive behavioral therapy, VR-based treatment may involve adjusting the<unk>  environment, such as for example adding controlled intensity smells or adding and adjusting vibrations, and allow the clinician to determine the triggers and triggering levels for each patient's reaction. VR-based therapy systems may allow replaying<unk>  scenes, with or without adjustment, to habituate the patient to such environments. Therapists who apply<unk>  reality exposure therapy, just as those who apply in-vivo exposure therapy, can take one of two approaches concerning the intensity of exposure. The first approach is called flooding, which refers to the most intense approach where stimuli that produce the most anxiety are presented first. For soldiers who have developed PTSD from combat, this could mean first exposing them to a<unk>  reality scene of their fellow troops being shot or injured followed by less stressful stimuli such as only the sounds of war. On the other hand, what is referred to as graded-exposure takes a more relaxed approach in which the least distressing stimuli are introduced first. VR-exposure, as compared to in-vivo exposure has the advantage of providing the patient a vivid experience, without the associated risks or costs.<unk>  has great promise since it historically produces a "cure" about 90% of the time at about half the cost of traditional cognitive behavior therapy authority, and is especially promising as a treatment for PTSD where there are simply not enough psychologists and psychiatrists to treat all the veterans with anxiety disorders diagnosed as related to their military service.<unk>  is also a promising adjunctive therapy for the treatment of other clinical populations, such as individuals with psychosis. A recent systematic review of psychosocial interventions using<unk>  reality shows these interventions are safe and well accepted in this population. The studies identified in the review show that psychosocial<unk>  can improve cognitive, social, and vocational skills as well as symptoms of auditory verbal hallucinations and paranoia in individuals with psychosis. Recently there have been some advances in the field of<unk>  reality medicine.<unk>  reality is a complete immersion of the patient into a<unk>  world by putting on a headset with an LED screen in the lenses of the headset. This is different from the recent advancements in augmented reality. Augmented reality is different in the sense that it enhances the non-synthetic environment by introducing synthetic elements to the user's perception of the world. This in turn "augments" the current reality and uses<unk>  elements to build upon the existing environment. Augmented reality poses additional benefits and has proven itself to be a medium through which individuals suffering from specific phobia can be exposed "safely" to the object(s) of their fear, without the costs associated with programming complete<unk>  environments. Thus, augmented reality can offer an efficacious alternative to some less advantageous exposure-based therapies.
