Applications
As Virtual Reality has gained traction in the real world, scientist and researchers have started to think about their use in various fields like medical science, gaming and education.
· Medical Science – One of the most common uses of the virtual reality is in Virtual Reality Exposure Therapy (VRET) which treats the patients
suffering from some specific anxiety or phobias. Patients are gradually introduced to the negative situations in a virtual environment until they become desensitized and are able to handle with their fear or anxiety. The diseases like acrophobia (the fear of heights), Agoraphobia (fear of spaces), Arachnophobia (social phobia) are treated using the VERT therapy. Virtual Environments (VEs) are also used to study the patient’s reactions and behaviors to high anxiety environments. Medical students, doctors and nurses are taught the basics of human anatomy as well as surgical procedures by creating 3D virtual models.

The simulation of environments using sensory immersion has been proven an effective training method. Training in monitoring and verification of performance is as simple as simulating the normal and abnormal conditions within the workplace environment. Simulations can be distributed to centers to be used by the trainers or trainees, and new environments and conditions can be added easily. The use of virtual reality is also increasing in military, especially to train pilots by developing special flight simulators which provide pilots a safer and less expensive way to learn flying skills. Also Virtual simulations of conflict scenarios have been used to teach soldiers how to make quick and effective decisions under stressful circumstances.

An example of a simulation tool is ‘MaxwellWorld’, which is designed to help students understand the concepts of electrostatic fields. Generally students have trouble understanding the relationship of abstractions about electric fields to phenomenological dynamics. The MaxwellWorld enable learners to virtually experience scientifically accurate models of electric fields and make factors significant that are not noticeable in the real world like how forces at each point in space continually accelerate a test charge through 3D interactive imageries.· Gaming – Gaming is another industry where virtual reality technology is deployed and resultantly we have more interactive and entertaining games with us. These 3D games use a high definition helmet mounted with LCD or LED screen and 3D stereo headset. The gamers are highly immersed with the gaming scenario and the characters and objects interact with the gamer like live things. Some companies like Sony are now involved in developing games augmented with the VR technology.
