Domestic Research Hot Spots and Frontier Analysis of Virtual Reality Technology in the Field of Education

2.1 Birth of Virtual Reality

The first idea of virtual reality was given by Sutherland (1965) known for the father of computer graphic and created the first Helmet-Mounted Displays (HMD) and head tracking system in 1968 and laid the foundation for the VR (Liu et al., 2017). The progression period started and in 1980’s first viewing system was developed by NASA in Virtual Planetary Laboratory. Foley (1987) discussed in detail the concept of virtual reality interface, hardware and application of VR. The term virtual reality was first suggested by Lanier (1989) and developed VR technology for the specific product and since 1990s, the progress and development in the simulation environment of virtual reality and the application is continuously growing across the world in the different norms. Year of 2016 is known for the year of artificial intelligence and virtual reality where big technological companies have shown much interest in the VR technology. since the industrialization and commercialization of VR technology in past two decades. Despite the emergence of virtual reality for over five decades yet much research studies are required to work in the field of VR in education and health etc. VR not only deals with computers or technology but also deals with human psychology (Coelho et al., 2006). VR is the mixture of multiple media devices in a 3D environment such as audio, image and video and much different than traditional multimedia (Riva, Waterworth, & Waterworth, 2004).
