![]() Virtual reality technology is used in a variety of fields and possible medical application has attracted keen interest. Another distinguishing characteristic is that VR gives the illusion that objects that do not exist in the real world exist inside a computer-generated VE. The distinguishing characteristic of VR is a sense of immersion that occurs from the user interacting with a VE using multimodal stimuli, such as visual, auditory, and tactile stimuli. ![]() Virtual reality (VR) consists of indispensable elements including a virtual world, immersion, sensory feedback, and interactivity. In 1990 the human machine interfaces for teleoperators and virtual environments conference was held in Santa Barbara, CA and virtual reality was given as a general term for all related technologies. It is widely credited that Jaron Lanier, director and founder of VPL ( Visual Programming Language), coined the term virtual reality in 1989 to bring all of the virtual projects of VPL, such as eyephone, dataglove and datasuit under a single term. This resulted in the construction of the Super Cockpit in the 1980s which Tom Furness created as the director of this project. The US Air Force established a laboratory at Wright-Patterson Air Force Base in Ohio and created flight simulators for high speed military aircraft. During the 1960s and 1970s, virtual reality technology had been applied to aerospace and military fields. He also developed a head mounted display which was designed to immerse the viewer in a visually simulated 3D environment. ![]() In the fields of computer graphics, Ivan Sutherland created the pioneering virtual reality system, The ultimate display in which he used computers for the designing, construction, navigation and habitation of virtual worlds. The virtual reality technology developed in the 1960s is similar to what we see in the present day. These technologies, such as computer graphics, simulation, and human-computer interfaces have all led to the evolution of virtual reality technology. Virtual reality is state of the art technology, but its concept can be found in many fields even in the past. ![]()
