What Is Virtual Reality (VR) And How Does It Work?

In a world where people are distanced because of the global pandemic, VR has gained a totally new significance over the past year. Although virtual reality has already become a common technology in the 21st-century world, most people are still unaware of its multifunctional properties. Nowadays, the scopes of VR applications continually expand, engaging more and more industries. At the same time, the need to explore modern technologies also grows, motivating people to search for trustworthy information concerning virtual reality. Do not miss your chance to discover the world of virtual reality, read our new article, and keep up with the times!


Virtual reality (VR) is a computer-generated illusion of the real world that immerses people into a simulated environment and provides visual, audio, and haptic senses. When we put on a VR headset, it takes us into the fictitious world, completely separating us from the real surroundings. By convincing the human brain that it is somewhere it is really not, VR makes it possible to experience anything, anywhere, and anytime. The ultimate goal of virtual reality is to provide an experience that feels so real that you forget it is an artificial environment and begin interacting with it. On the one hand, it may be a completely synthetic world. On the other hand, it may mimic the features of a real-world environment. Hence, everything depends on the purpose of VR utilization.

How Does Virtual Reality Work?

How does a virtual reality headset make you think you are visiting another country when you are staying in your bedroom? The answer to this question is pretty simple – a life-like virtual environment makes your brain trust that everything around you is real. The video is sent via cable to the headset or through the phone fitted into the headset. VR headsets have two small LCDs placed next to each other, like glasses or two feeds sent to one display showing pictures of the same object that are slightly shifted towards one another. This technology creates an illusion of 3D space.

Tracking Options

Head Tracking

This tracking option works due to the ability to follow the user’s head motion. A system called 6DoF (six degrees of freedom) marks your head regarding your X, Y, and Z-axis to take the measurements of head movements forward, backward, and shoulder to shoulder. It includes one of the three components, such as a gyroscope, accelerometer, and magnetometer, that are usually used to track objects.

Eye Tracking

One more incredible feature of VR technology is the function of eye tracking. The infrared sensor tracks your eyes inside the headset, so the headset recognizes what you are looking at. By tracking the direction of your eyes inside a virtual environment, this technology makes your immersion more realistic.

Hand Tracking

This essential option provides a unique sense of presence, intensifies user engagement, and provides more natural interactions with articulated fingers. Notably, there are two possible scenarios of hand tracking. First, it may be performed with the use of special gloves. Watch how it works with our PPE Virtual Reality Training Simulator for HTC VIVE with full-hand tracking. Second, integrated hands without any additional equipment can also deliver object interactions utilizing simple hand gestures. See how it works here – VR Job Training for Retail, Cafe, Fast Food.

Motion Tracking

Motion TrackingThere is no doubt that motion tracking relates to the cohort of VR’s most significant benefits. If you want to achieve complete immersion, motion tracking is the key to break all limits, enabling you to look and move around the virtual environment. Thanks to 6DoF and 3D space, there are two motion tracking options – optical and non-optical tracking. Optical tracking is generally a camera on a headset that follows the movements, while the non-optical tracking option usually incorporates the use of other sensors on a device.

How Much Does It Cost to Develop VR Application?

The cost of application development depends on multiple factors, including your goal, design preferences, project’s key features, etc. VR applications have become a real successor in many industries from gaming to healthcare. After all, by immersing customers or employees, businesses and organizations have an opportunity to interact with them much more cost-effectively. Why is VR training so reasonable?

Limitless Scopes of Application

Even though virtual reality was initially created for gaming and video, this technology is used in a wide variety of other industries today. VR is successfully applied in education, science, medicine, design, architecture, engineering, gaming, and entertainment, to mention just a few. There are so many different areas that it is even difficult to describe all of them in one article.

Summing Up

In conclusion, virtual reality is considered an inseparable part of modern life. With such a wide range of opportunities, VR is undoubtedly worth your attention because it may improve your life in many diferent ways, ranging from business to personal use.
