What is VR?

Key Takeaways

Virtual reality, or VR, is a computer-generated environment that gives people the illusion of existing and interacting in a synthetic world. Using high-resolution graphics, 3D models, and wearable technology, such as headsets, VR users experience an immersive, multi-sensory environment with various applications, including gaming, education, and training. Some important things about this exciting technology are:

• The demand for specific VR applications across various verticals continues to grow, resulting in numerous career options for those interested in this evolving technology.

• While many consumers associate virtual reality with gaming, it has other industrial and commercial applications.

• The market for VR is growing. According to data from Fortune Business Insights, the global virtual reality market is projected to reach $123 billion by 2032, representing a significant increase from $20 billion in 2025 [1].

To pursue a career in VR, you can earn a degree in a tech-related field like computer science or information technology, or hone your skills through industry-leading boot camps and online courses like Introduction to Virtual Reality, where you'll review the history of VR, explore its applications, and consider its challenges.

Types of VR

Before pursuing a career in virtual reality, it's essential to understand the three basic types of VR. The type of VR varies based on an immersive scale, from non-immersive to fully immersive.

Non-immersive

The best way to explain non-immersive VR is to think of a video game or a simulation. You experience a computer-generated world. However, you remain fully aware of your physical surroundings as a player. In other words, you interact with VR displayed on a TV screen or smartphone rather than becoming part of it.

Since many assume that VR must be immersive, this type of VR is often overlooked. 

Semi-immersive

Semi-immersive VR uses high-resolution 3D graphics to create an environment that allows you to fully experience the game or VR world while remaining aware of your physical surroundings. Uses of this type of VR include training. For example, companies can use it to train mechanics on the parts of a car required for garage work and on methods for repairing and maintaining vehicles. 

Fully immersive

With fully immersive VR, the virtual world will feel real—you'll feel part of it. You see, hear, and can even interact with the simulation. Designers create artificial environments through graphics, sights, and sounds loaded onto various wearable technologies, such as headsets, gloves, and body sensors. 

What is VR used for?

While many consumers associate virtual reality with gaming, it has other industrial and commercial applications. It can train doctors and nurses in the health care field, provide immersive education, and generate gamified exercise to improve fitness levels.

Additional applications include: 

• Virtual home tours

• Virtual fashion shows

• Demonstrate products at conferences and events

• Provide training in specific industries

• Cybersecurity audits

• Facilitate remote repairs

• Athlete training

Pros of using VR

The benefits of virtual reality range from educating and entertaining the masses to providing visualization of items otherwise challenging to describe. Let’s explore some advantages of using VR to understand its scope and potential. 

Improved educational opportunities

People in many industries can learn new skills or complete training with VR. It enables individuals to hone their skills and helps companies boost engagement and morale.

New entertainment

VR has found a home in the world of online gaming. It is also emerging as a player in alternative ways to enjoy live music, experience new destinations without ever leaving home, and experience movies and shows in a new way.

Simultaneously, the availability of affordable VR components, such as headsets, has entered the market, contributing to the industry's growth.

Visualization of buildings and products

By using virtual reality, you can illustrate ideas, concepts, and products that would otherwise be challenging to explain. With VR, you can provide architectural drawings, offer virtual tours of office space or a home, or create prototypes for a new product before building a physical one. 

Cons of using VR

As with any technology, VR has potential drawbacks. The disadvantages of virtual reality center on tech issues, health challenges, and privacy concerns. 

Tech problems

Tech issues exist for both users and creators. VR users may experience latency issues, which are delays between the VR hardware and its complementary software. The result is a jittery experience, which can diminish its entertainment or educational value. 

You need a computer with advanced graphics capabilities to create a sci-fi world for a VR game or to simulate open-heart surgery for medical training purposes. These types of computers can be hard to find and often come with a high price. 

Health challenges

VR users have reported several side effects, including nausea, headaches, or disorientation, commonly referred to as "cybersickness," which is similar to motion sickness caused by the immersive environment. Since many VR applications utilize a head-mounted display, users may bump into objects in their real-world environment or trip and fall.  

Privacy concerns

As with any application, VR requires security measures to protect data and prevent unauthorized access by hackers. However, research from Rutgers University has examined how voice command features on headsets can give hackers an open door to "eavesdrop" and capture spoken data, such as a person's credit card number [1]. While measures to tighten security are being implemented, it remains a continued source of trouble for many VR brands.

How to pursue a VR career

The market for VR is growing, and the demand for VR is already impacting the workplace, with many companies enhancing current jobs with VR components or adding new positions specifically for VR implementations and oversight.

If you're interested in a VR career, you must have a passion for the technology and seek education about it. You could pursue a degree,  explore boot camps or online courses, or consider certification to learn the necessary skills. 

Consider attending college.

While you might be able to find a few degrees specializing in virtual reality development, they're rare. People in this niche usually focus on a more general degree like computer science, information technology, or a related field.

Consider bootcamps and online courses.

A computer science degree will offer the background you need, but you may also need specific courses to help you tailor your skills for a particular job. For example, if you're interested in pursuing a career as a VR software developer, you may need additional education in 3D modeling, design software, or game development. If you prefer to work on VR hardware, classes focusing on modern electronics or computer hardware engineering could be helpful.

Develop human and technical skills.

As you might suspect, working in VR does require technical skills, including:

• Proficiency in coding languages like C++, C#, or JavaScript

• Experience with 3D modeling and rendering

• Awareness of VR hardware and software

While the VR industry places a strong emphasis on technical skills, human skills are also essential. To work in this industry, you'll need:

• Communication skills

• Collaboration skills

• Problem-solving skills

Understand your career options.

When you're ready to pursue a job in the field, knowing what kind of jobs and job titles to look for is helpful. Jobs could include:

• VR content producer: Create digital content that includes the use of VR.

• 3D artist: Use software to create 3D worlds and special effects.

• Programmer: Write and test code to create or improve operating systems or software.

• UI designer: Create visual elements that contribute to a site or video game.

• UX researcher: Analyze data to improve a customer's experience with a product.
