Virtual Reality – Meaning, Types, Equipment, Advantages And Disadvantages Of 3D Virtual Environment

Has your brain been tricked? Have you ever imagined being in a video game with warriors and scary, dangerous, gigantic animals like a dragon? That explains Virtual Reality better. It feels like being in a 3D virtual environment or travelling into another world entirely.

It is used in entertainment applications commonly found in Video games, amusement parks, dark rides and 3D cinemas.

Virtual reality is a computer-generated three-dimensional environment that can appear to be real, giving users an immersive feel of a virtual world. Users interact with this environment using special electronic devices like gloves fitted with sensors, VR headsets or helmets.

Types Of Virtual Reality

There are 3 categories of VR simulations: Non-immersive, Semi-immersive and Fully-immersive. Which one have you tried out?

Non-immersive VR:

 Non–immersive virtual reality is the type we are already common with. It provides a computer-generated environment but allows users consciousness of their physical environment. Non-immersive VR has input devices like gamepads, keyboards and mice.

Semi-immersive VR:

This provides users with a partial virtual environment. Hence, users simultaneously perceive they are in a different reality when they centre on the digital picture and remain conscious of their physical atmosphere. This type is mainly used for educational training and depends on high-resolution displays, projectors and powerful computers.Semi-immersive VR

Fully-immersive VR:

Fully-immersive virtual reality, as the name goes, gives users a completely realistic simulation effect, full of sound and sight. Users need VR glasses and head mount displays (HMD) to involve and connect with fully-immersive virtual reality.

The VR glasses utilize a method called head-tracking, which modifies the visual field based on the user’s head movements. These glasses offer high-quality content with a broad range of vision.Fully-immersive VR

Equipment You’ll Need To Operate A VR Game

When considering a VR game, it is important to prioritize the space required for playing the game. This is because the game involves movements of the arms and body, and it is recommended to play it in a room that has enough space to avoid any injuries that may occur from hitting obstacles.

To enjoy a virtual reality game, you will also require a wireless headset, such as the Meta Quest 2 or Pico 4, as opposed to a tethered headset like the HTC Vive. The advantage of a wireless headset is that it eliminates the need to buy gaming computers to operate it.

There are additional accessories available that can improve your gaming experience, but they are not necessary to play the game. However, certain accessories, such as fitness and haptic accessories, can greatly enhance your virtual reality game.

Advantages And Disadvantages Of Virtual Reality

As with any other invention, Virtual Reality has pros and cons. It is essential to be aware of the exciting and enjoyable aspects of Virtual Reality, the concept of an unreal environment, and its drawbacks. However, it is unnecessary to be overly fearful and miss out on virtual reality’s entertainment, learning and creative benefits.

Advantages of Virtual Reality

1. Mitigates Phobia

Virtual Reality has proved to be a valuable tool for aiding people in the force. The simulations are designed to replicate real-life scenarios, allowing military patients to cope with incapacitating tension.

In addition, Virtual Reality can alleviate phobias by providing a better understanding of the fearful environment. Furthermore, it enhances patients’ motor skills and facilitates physical rehabilitation.

2. Edutainment

Virtual Reality (VR) has the potential to assist students and professionals in reconstructing complex tasks and projects that may be challenging to comprehend in reality. Although VR is often associated with entertainment, it is also a valuable resource for medical practitioners and surgeons to learn about anatomical structures.

Additionally, VR is a safer alternative for the aviation and automobile industry. Pilots can receive simulation training to prevent accidents, and aspiring drivers can also undergo VR training for the same purpose.

3. A Way To Explore Places

With the ever-changing technological landscape, Virtual Reality (VR) is a valuable asset for technology enthusiasts. VR enables us to discover various locations worldwide without leaving our current location.

Consider the scenario where you desire to visit a specific destination while sitting on your couch; VR makes it possible to tour that place without any expenses. The realistic experience provides an overview of the site, which can aid in planning a trip in the future.

4. Communication and Interaction

Virtual reality headsets make it simpler to interact with other people within virtual reality environments. As this technology is currently at its highest point, you will always be able to meet new friends.

Consequently, virtual reality offers numerous opportunities for you to connect and communicate with others, sharing your experiences with people connected through social media. It’s an excellent way to hang out with friends through virtual reality, and social media platforms using this technology can revolutionize your previous experiences.

Disadvantages Of Virtual Reality

1. Virtual Reality Confines You In Reality 

The longer one spends in a virtual environment, the greater the likelihood of feeling disconnected and isolated. This can result in difficulty expressing oneself in public and private settings, making it challenging to establish meaningful relationships.

As humans, we thrive on interpersonal connections with family and friends, and relying too heavily on virtual reality can lead to a disconnection from the real world. Therefore, it is important to recognize the potential dangers of excessive virtual reality use.

2. VR Can Cause Eye Strain

Virtual reality headsets have two small LCD monitors placed very close to your eyes. This proximity can increase the likelihood of developing eye problems if used for extended periods.

Eye strain is the most common eye problem that can arise from using VR headsets for long periods. This is caused by prolonged focus on a single object, such as watching a lengthy movie or staring at a computer or smartphone screen for extended periods.

3. Weakens Educational Flexibility

Relying exclusively on software-based simulations in a class can negatively affect students’ mental capacity and flexibility. This is because it reduces verbal interaction between instructors and students, as answers are predetermined, and no cross-questions are allowed.

Real-time interaction suffers when teachers and students follow programmed instructions and guidelines. It is important to remember that education should not be limited to software programs alone.

4. Virtual Reality Is Addictive 

The longer you spend immersed in virtual reality, the greater the risk of becoming disconnected from the real world and developing an addiction to VR. It can be difficult to track how much time you’ve spent playing video games, and it’s important to remind yourself that it’s not real life.

It’s crucial to re-engage with reality and not get lost in virtual reality for extended periods.

Conclusion

Determining precautionary measures when dealing with constantly evolving technology like Virtual Reality can be challenging. Despite the potential drawbacks, such as addiction, it is important to recognize the positive impacts that Virtual Reality has in most educational fields.

Therefore, it is important to weigh the advantages and disadvantages of considering implementing VR in educational and creative sectors as a potential solution to balance the equation.
