How Does Virtual Reality Work

Have you ever wondered how does virtual reality work? Well, you are not alone. Virtual reality is overtaking the real world and you cannot help but come into contact with virtual environments.

What is a virtual environment? A virtual reality space is said to exist when a 3D computer generated world has been created. This world must allow users to interact with the environment and each other and leave the user with the feeling that he is actually in the virtual environment.

Universities and schools use virtual reality to interact with students. Businesses use virtual reality to communicate and to advertise. Online gaming uses virtual reality to create realistic gaming scenarios. The uses of virtual reality are endless.

For an experience to qualify as a virtual reality experience it must both immerse you in the virtual world and allow you to interact with the environment and others in the environment. The combination of immersion and the ability to interact is known as telepresence. If either of these qualities is missing you will not have a true virtual experience.

How Does Virtual Reality Work? Dive Right In!

To understand how virtual reality works you must understand the concept of immersion. Immersion allows users to feel as if they exist within the virtual world. In order for a user to feel he is in a virtual world the world must appear to be a regular sized world where perspectives and movement can be achieved effortlessly.

Immersion includes such concepts as sight and sound. A user must be able to see in the virtual world as he does in the real world. If looking at a tree the user must be able to walk around the tree and view it from many perspectives.

Sound is a major component of how virtual reality works. In the real world sounds are heard in different volumes, pitches, and tones depending on where you are and how you are moving. A virtual world must recreate this experience.

If a user becomes aware of the real world environment the virtual world has failed. The goal of immersion is for the virtual world to mimic the real world to the point that a user will be “lost” in the virtual environment and forget he is using a computer or that the real world exists.

How Does Virtual Reality Work? With Inter-Action

The second component of a virtual world, and a driving force behind how a virtual world works, is interaction. Users in the virtual world must be able to interact with other users and the virtual environment.

Interaction with others in virtual worlds can be accomplished via text or speech. A keyboard will allow users to communicate with other users in text format. Microphones and headsets let users communicate using speech.

Interaction with the environment means that the user has the ability to move objects in his environment. The virtual user can move in the virtual environment and do many things he would in the real world.

As with immersion, interaction must be seamless. There should be no lag time between your real life movements, (or speech), and the corresponding actions in the virtual world. Lag time will cause the virtual experience to be limited.

Understanding how virtual reality works will make your life easier. Many virtual reality programs are currently being created to make users’ daily lives more pleasant. Once you understand how virtual reality works you can dive into the virtual world.
