Virtual Reality Explained: Benefits, Challenges & Future Trends

Virtual reality allows people to experience the world in ways they never could before. Ever wondered what it would be like to stand on top of a waterfall, fly with the birds, or visit Paris for a couple of hours? VR technology gives you the ability to go on adventures and travel around the world—even outer space—without leaving the comfort of your home.

Although this may seem futuristic or inaccessible, there’s a solid chance virtual reality is in your life already. For instance, many video games allow players to engage with virtual worlds and characters, using VR technology to make the experience feel more real.

In this article, we will discuss what virtual reality is, the pros and cons of virtual reality technology, its limitations, and what the future holds.

What is Virtual Reality?

Virtual reality (VR) refers to a computer-generated simulation or recreation of a three-dimensional (3D) environment that users can interact with using specialized hardware and software, such as a VR headset or helmet. This technology creates an immersive illusion that the user is somewhere else.

There are three types of virtual reality: non-immersive VR, semi-immersive VR, and fully-immersive VR. Each one offers varying levels of immersion and interaction, catering to different use cases and budget considerations.

Here’s an overview of each:

Non-immersive VR

Also known as desktop or 3D VR, non-immersive VR is the most basic form of virtual reality. In this type, users experience virtual environments through a computer screen or a handheld device, such as a smartphone or tablet. This means that users can view the virtual world on a screen and observe their real-world surroundings simultaneously.

Some examples of non-immersive VR include virtual tours, 360-degree videos, and flight or driving simulators.

Semi-immersive VR

Semi-immersive VR offers a more immersive experience than non-immersive VR but does not fully engulf users in a virtual environment. In this type, you typically wear a head-mounted display (HMD) that covers only part of your field of view.

The HMD may include motion tracking, allowing you to look around the virtual space by moving your head. However, your body movements are not fully tracked, which can limit the level of immersion.

Applications of semi-immersive VR include gaming experiences and training applications where you can interact with virtual environments through your head movements.

Fully-immersive VR

The third type of VR—fully immersive—provides the highest level of immersion and presence, offering a realistic and seamless virtual experience. For this type, you can wear special head-mounted displays (HMDs) or VR goggles that cover your eyes and ears.

These allow for 360-degree view and sound, which creates a real sense of presence within the virtual world. The displays also typically have high-resolution screens for each eye that can help enhance depth perception.

With this gear, you can interact with the virtual environment using both head and body movements. Some fully-immersive VR setups include additional accessories, such as motion controllers or haptic feedback devices, to further enhance the experience.

Examples of fully-immersive VR include high-end gaming experiences, virtual simulations for medical training or pilot training, and advanced architectural visualization tools that allow users to walk through virtual buildings.

Difference Between AR and VR

While augmented reality (AR) often comes up in conversations about VR, there are notable differences between the two. The underlying technology is, in fact, closely intertwined, but AR is basically the cousin of virtual reality.

A defining characteristic of AR is that it still has one foot in the real world. The technology simulates artificial objects within reality, meaning objects and images are placed in the real world. Virtual reality, however, doesn’t feature any existing territory and instead happens within an entirely artificial environment.

One of the most well-known examples of AR is the game Pokémon Go. In it, you can walk around your neighborhood while virtually catching Pokémon.

It’s worth noting that although VR and AR are different, they can be used together. For example, both are fields of the Metaverse, which you can learn more about here.

Benefits of Virtual Reality

VR technology, when used for good purposes, can offer endless possibilities, opportunities, and excitement. It can benefit various fields and industries, such as education, medicine, architecture, and entertainment. The technology can also simulate senses such as hearing, touch, and even smell.
