Introduction To Virtual Reality

1. INTRODUCTION TO VIRTUAL REALITY

Computer is one of the most widely used device by all the group of age of user, in almost every aspect of our daily life. Virtual reality (VR) is the new era of technology. It plays the most important role in the revolution of computer and technology. The meaning of virtual reality exists in the word itself. ‘Virtual’ means almost and ‘reality’ means real, which we human face every day. So ‘virtual reality’ simply means ‘almost real’. "Virtual reality can be defined as a three-dimensional, computer-generated simulation in which one can navigate around, interact with, and be immersed in another environment. Virtual reality provides a reality that mimics our everyday one." (Briggs, 1996). Virtual reality

Applications

Virtual reality has offered various benefits to the user and society in various fields. As it is one of the ongoing system of science and technology, the interest of people toward it is increasing day by day. Many inventors and scientists are working for new creation and better development of existing virtual environment and peripherals used in it. Areas like medicine, military, gaming, education, manufacturing, scientific visualizations, etc, all are using the virtual reality system to make their working more convenient and easy to use.

3.1. Medicine area Previously, medicine field was based on theoretical study and plastic model. And now with the help of virtual reality, the medical students can study practically in 3D form. VR has also help in the rehabilitation centers, aged people, children and other medical conditions.

Physical and mental fitness has to be in balanced form for a person to remain healthy. As the time pass by, people start facing problems of aging factors like memory loss, losing the capacity to learn, hard to perform physical activities (Sofi et al., 2010). With the help of VR, aged people are introduced to video games which make them exercise mentally and physically (Pedraza-Hueso et al., 2015). Platforms like PlayStation, Wii Balance, Xbox, Wii provides a physical system through which the user can interact physically (Roy et al., 2013). Likewise, it has also been used with the antidepressant treatment (Castro et al.,
