what is virtual reality?

Virtual reality (VR) is a simulated experience that can be similar to or completely different from the real world. Applications of virtual reality include entertainment (e.g. video games) and education (e.g. medical or military training). Other distinct types of VR-style technology include augmented reality and mixed reality.

Virtual reality is a realistic, three-dimensional computer-generated environment that can be explored and interacted with by a person. That person becomes a part of that environment and can manipulate objects or perform a series of actions.

The goal of virtual reality is to create a simulated environment that is so realistic and convincing that the person interacting with it suspend disbelief and accept it as reality.

There are a number of different virtual reality systems available on the market today, ranging from high-end systems designed for gamers and movie fans to lower-cost options that are more accessible to the average consumer.

How Virtual reality came about

In the late 1960s, computer science professor Ivan Sutherland and his student Bob Sproull created the “Ultimate Display,” a head-mounted system that allowed a user to see computer-generated imagery. This was the first true virtual reality (VR) system.

Sutherland’s system was extremely primitive by today’s standards. It used a bulky CRT monitor for each eye and was so heavy that it had to be suspended from the ceiling. But it was a breakthrough nonetheless, and laid the groundwork for the development of modern VR systems.

In the 1980s, NASA began using VR to train astronauts for space walks. In 1992, the first VR game, “Dactyl Nightmare,” was released for the Commodore Amiga. And in 1994, the first VR headset for consumers, the Virtual Boy, was released by Nintendo.

Since then, VR has come a long way. Modern VR systems are far more advanced, and can provide a much more immersive experience. But it all started.
