What is virtual reality?

Virtual reality (VR) is an intelligent use of computer technology to provide simulated experience to the user. It is an artificial environment introduced to the user in a way where the user considers it as a real environment by suspending its belief. It gives the user a ‘near-reality’ experience where the user feels as if he/she is present there. Any users can experience virtual reality using their two senses, i.e. sight and sound.

 The virtual reality gives the user an immersive experience by 3-D images in its simplest form. The images can be explored and interacted with by the user at personal computers. The interaction is done by controlling the mouse or keys that provide direction to the image contents or to increase or decrease the magnification. Techniques such as covered display screen, the actual rooms that are upgraded with wearable computers, the tactile devices, that allow the user to feel the pictures displayed on the screen.

Virtual reality can be categorised as:

  1. Creating a virtual environment of training and education as a replica of the real environment.
  1. The development of an artificial environment for a game or story for entertainment.

Main Features of Virtual Reality:

  • Immersion:

The main motive of the virtual reality is to immerse the user entirely into the real-like virtual environment. The secondary vision of VR contains the use of a visor and noise-cancelling headphones. It takes the user into a virtual world and allows them to control the scene with their body movements. The immersive experience can be created by introducing three-mentioned control levels. The experience can become more powerful by the addition of new features for interaction.

  • Interaction:

In the field of entertainment such as films and games, app creators generate such applications or elements that provide the user with a more immersive experience. For example, the use of the specialty controller in the new PlayStation VR helps the user to interact and control the elements effectively. The immersion can be improvised by adding more valuable features such as providing the ability to select the objects and interact with the players. These features can add value to the VR simulations.
