How Does VR Technology Work?

Updated: Mar 4

Are you familiar with VR technology and how it works?  Are you aware of the vast amount of benefits this ever developing and advancing technology can offer you and your business?  From understanding just exactly what VR Technology is to the specifics on how it works, there is so much to learn! Let’s take a closer look at VR Technology!

What is VR Technology?

Before truly understanding how VR Technology works, it’s important to first understand just what VR Technology is.  VR Technology is a computer-generated, interactive technology that takes place within a simulated environment.  It has the ability to encompass auditory and visual feedback but can also, at times, use other types of sensory feedback.  By using this computer-generated technology and all the possibilities of different sensory feedback, the user is able to design and create just about anything they desire and eventually produce it as a 3D, physical object!

How Does VR Technology Work?

Although there are many different sectors and types of VR Technology, let’s take an in-depth view at the basics of how it works.  Essentially, think of this technology as almost a “trick” for your brain.  You’re not really in a 3D world when you’re using it and any of the objects you might be creating aren’t truly 3D yet, either.  However, that’s the secret to VR Technology—your brain thinks you are!  To help you understand, let’s break it down into smaller pieces.

Stereoscopic Display

It’s a huge word that sounds intimidating, but the concept is actually quite straight forward.  This is the first way VR Technology convinces your brain that you’re in a 3D world, when, in reality, you’re not.  Stereoscopic Display works by showing two different angels of the scene, or object you’re looking at, to each eye.  So, one eye is seeing one version from a specific angle and the other eye is seeing it from just a slightly different angle.  This adds depth to what you’re seeing as well as giving depth to any objects in your view.


Yet another technique VR Technology uses to make a virtual world seem like reality is through Parallax.  Generally speaking, parallax makes the objects closest to you move faster or at regular speed, whereas, objects further away from you move slower.  This adds yet another layer of realistic movement to your VR experience.

Field of View

The field of view is also enormously important when discussing how VR Technology works and just why it’s so very successful.  First and foremost, the field of view is defined as “the extent of the world that is visible to the human eye at any given time.”  So, in general, us humans, on average, when looking straight ahead can see everything within a 180-degree angle.  When we move our eyes side to side, we’re able to view things at a 270-degree angle.  When you work with VR, this is an important factor because the human eye is extremely good at picking out imperfections in vision and therefore, VR Technology has to work that much harder to ensure your eyes and brain are convinced.


Last, but certainly not least, speed and the rate you’re viewing things in VR makes a huge impact in the overall way VR Technology works.  For example, if the images you’re seeing with the VR are too latent, there is simply no way your brain will be tricked into thinking what you’re seeing is “real.”  Essentially, anything slower than 20 milliseconds won’t be fast enough to trick your brain into believing what you’re seeing is actually real.  Therefore, for VR Technology to work properly, speed and latency are massive attributes.

The Bottom Line

VR Technology is a complex, ever developing and quickly advancing technology.  It’s becoming one of the most efficient and advanced way to design, create and produce objects in the world—from machines that make our clothing to things like video games.  That being said, there are many factors that go into VR Technology and all of them are vital into convincing our brains that what we’re seeing is “real.”  From the speed at which we view images, to how fast or slow the object move in combination, to the field of view we’re shown and even down to the angles we see the images through, it all comes together to give us a VR experience.  Virtual Reality is always developing and changing but it is, nonetheless, one of the most popular technologies out there right now and utilizing it, in any form, can greatly benefit your business!
