Recently there have been some advances in the field of virtual reality medicine. Virtual reality is a complete immersion of the patient into a virtual 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 virtual 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 virtual environments. Thus, augmented reality can offer an efficacious alternative to some less advantageous exposure-based therapies.
