Understanding Virtual Reality: A Closer Look at How It Works

Understanding Virtual Reality (VR) is an immersive technology that has exploded in popularity in recent years. It enables users to be transported to virtual worlds and to feel as though they are truly “there” through the use of computer technology and sensory equipment, such as screens and sensors. But what, more precisely, is VR, and how does it work?

At is heart, VR is simply a three-dimensional, computer-generated environment that one can explore and interact with. When you put on a VR headset, an individual is truly transported to a different place and time.

What’s happening when this occurs? Just how does VR work? To answer that, we’re going to have dive into the technology behind this.

Display and Headsets:

The most well-known piece of VR gear is the headset. Basically, it is a display (or two) that takes up the user’s field of vision.Headsets include lenses that change the flat image on the screen into a stereoscopic 3D image. The monitors’ high refresh rates and combined with the lenses and the user’s persistance of vision helps to create the illusion of landscape you can see Microsoft HoloLens .

Tracking and Sensors:

For a more immersive experience, the headsets are equipped with sensors/trackers that track the user’s movements. These are generally made up of gyros and accelerometers, which detect orientation, and magnetometers, which detect direction. 

External sensors help to correct for the fact that a user’s hands or peripheral remain fixed in the real world, even while the user is, perhaps, moving around in a virtual world. These sensors may be anything from Kinect-style motion sensors to the more familiar game system motion detector like the PlayStation camera.

Audio and Sound:

Sound might not be an effect of vision, but since the brain usually uses what it sees to process the sounds it hears, it functions like it is. This is beneficial for a couple of reasons. First, what the user hears can give them the illusion of space they see. Second, in addition to looking around, users like to look with the ears: wherever they hear a sound from. The company RealSpace 3D has created a sound system that uses algorithms to detect how sound should act in a virtual environment, and mimic it.

Content Creation:

Behind every virtual reality experience is a team of content creators. They use specialized software and tools to design and develop the virtual environments, objects, and interactions. From gaming to education, virtual reality content spans a wide range of applications. Developers utilize 3D modeling, animation, and programming to bring these virtual worlds to life.

Rendering and Processing:

To ensure smooth and realistic visuals, virtual reality relies on powerful computer hardware. The process of rendering involves generating the images and graphics in real-time as the user interacts with the virtual environment. This requires high-performance processors and graphics cards to handle the complex calculations and deliver a seamless experience.

Connectivity and Interaction:

Virtual reality is not limited to individual experiences. With the growth of social tools, you can now connect with others in the virtual world. You can share the same graphic environment and talked to each other as your virtual avatars move around a scene.This shift to social virtual reality will have implications for games, as you can race or play with others, and for virtual field trips, if you want to learn in the Comte Basin with your classmates.

The Oculus Rift, Vive, and PlayStation VR—which is compatible with the PlayStation 4 gaming system—are a few well-known examples of these.

Applications of Understanding Virtual Reality:

Virtual reality has applications in a wide range of industries. In gaming, it has been used to create immersive gameplay experiences that transport players into fantastical environments relating to games as diverse as The Witness and Job Simulator. In healthcare, it is employed for training medical professionals and some forms of therapy. The Gear VR and Google Cardboard are two well-known examples.

With conditions such as PTSD and phobias, the technology has been shown to be a particularly effective treatment. Elsewhere, education, 3D modeling and architecture, tourism, and perhaps even therapy are likely to see revolutionary changes over the coming years as virtual reality takes hold.

Virtual reality is a computer technology that utilizes headsets, sometimes in combination with physical spaces or multi-projected environments, to create an experience that simulates a user’s physical presence in a virtual or imaginary environment.

VR is able to manipulate our senses by recreating realistic sounds and images. Thus, our minds can be tricked into believing it is somewhere that it is really not by simply creating a virtual environment that looks and sounds beautiful.

Simply put, virtual reality is the creation of a simulated environment by means of visual and auditory cues such as a headset and sensors often times paired up with the appropriate software and powerful hardware.

The world that is created is made believable by interacting with the conscious and unconscious parts of our psyche in allowing us to respond naturally like it is real. As VR technology continues to be constantly improved, we can look forward to a bevy of new and unique applications of the future.
