  • Jaron Lanier is the Founding father of Virtual Reality. He is an American computer philosophy writer, computer scientist, and visual artist.

“The computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen onside gloves fitted with sensors.”

Meaning:

  • Virtual Reality hardware is used in with software to show the user the environment that is not physically existed but it looked so real. Some VR hardware provides glasses, gloves and other accessories to simulate other senses like touch.
  • Virtual reality helps the user to interact with the environment or experience different type of world or dimensions.
  • We can use virtual reality for daily life. Ex., – Training and learning, healthcare, recruitment, tourism, meetings and everyday communication.
  • There are three main types of virtual reality, used to experience the world around us-
    • Non-immersive
    • Semi Immersive
    • Fully immersive

  • It’s important to keep in mind that semi-immersive VR simulations still give users the perception of being an indifferent reality.
  • This type of VR is not always possible to experience wherever. Instead, physical environments are created to supplement virtual reality.

Non-immersive Simulations:

  • Non-immersive simulations are used for video games.
  • VR allows for interacting with the environment through mouse or joystick.
