Introduction to Virtual Reality
What is Virtual Reality?
Today the Virtual Reality technology is applied to advance field of medicine, engineering, education, design, training, and entertainment. VR is a computer interface which tries to mimic real world beyond the flat monitor to give an immersive 3D visual expierence. Often is it hard to reconstruct the scales and distances between objects in static 2D images. Thus the third dimension helps in bringing depths to those types of objects.
A brief history on VR
Virtual Reality has been a part of technology for quite a long time actually. It can date as far back as to the 1800s, almost around the time of practical photography. The term "virtual reality" was first used in the mid-1980s when Jason Lainer began to develop what he called "gear" to expierence virtual reality.
Even before that, during 1956, the Sensorama was a huge milestone. Morton Heilig wanted to see how viewers of films would feel if they were "in" the movie. The sensorama expierence simulated a real city enviornment which the viewer would "ride" through a city on a motorcycle. Another inventor, Ivan Sutherland, offered "the Ultimate Display," a head-mounted device that he suggested would serve as a "window into a virtual world."
Jumping back to the 1970s and 80s, optical advances ran parallel to projects that worked on haptic devices and other instruments that would allow you to move around in virtual space. Today's current virtual reality gear owes a debt of gratitude to the pioneering inventors of the past six decades who paved the way to allow us to have access to the low-cost, high-quality devices now.
