What is the VR? How is Virtual Reality Made Possible?


The term “virtual reality” is derived from the words “virtual” and “reality.” When compared to the human experience, which is close to the notion of “real,” “virtual” seems far off. Therefore, “virtual reality” might be defined as “near-reality.” While this could signify anything, the term is most commonly used to describe a certain style of virtual reality.

Our senses and brains provide us with insight into the world. The five senses of taste, touch, smell, sight, and hearing were all taught to us in elementary school. However, these are merely the most noticeable of our senses. Humans actually have many more senses than this, including the ability to maintain their balance.

These additional sensory inputs, in addition to some specialized processing of sensory information by our brains, guarantee that our thoughts receive a wealth of data about the world around us.

Our senses are the only means through which we can gain knowledge about the world around us. In other words, what we take in through our senses and process through our mental machinery constitutes our whole perception of the world around us.

Logic dictates that if you can trick your senses into believing a lie, your view of the world will shift accordingly. You’d be shown a fake representation of the world that looks and feels real to you because of your unique point of view. The equivalent of what we call virtual reality.

To recap, VR is an experience where a computer-generated scene is presented to the senses and explored.

VR in Technical Terms…

In technological terms, it’s easy to explain what virtual reality is. The phrase “virtual reality” is used to refer to a fully immersive, computer-generated, three-dimensional world that a user can move around in and interact with. They enter the virtual world, become a part of it, and can do things like move around or interact with things while they’re there.


How is Virtual Reality Made Possible?

Although we discuss a few early examples of virtual reality elsewhere on this site, these days virtual reality is typically accomplished by means of computer technology. Headsets, omnidirectional treadmills, and specialized gloves are just a few of the equipment deployed toward this goal. Using all of our senses at once, help us believe that we are experiencing something real.

However, this is trickier than it sounds because our senses and brains have evolved to present us with a synchronized and mediated experience. With some practice, we can generally spot even the slightest deviation. Words like “immersive” and “realistic” start to get thrown around here.

There are technical and conceptual barriers that separate convincing or delightful virtual reality encounters from ones that are startling or unpleasant. The human body must be taken into account in the development of VR technologies.

The human visual field, for instance, doesn’t have the same proportions as a video frame. Although you may not constantly be aware of your peripheral vision, you would certainly miss it if it suddenly disappeared. Similar to how motion sickness can be brought on by a disagreement between what your eyes are telling you and what your vestibular system is telling you, dizziness is a common result.

This is a common occurrence for some people when they read in a moving vehicle or on a boat.

 In virtual reality, a sense of presence is achieved when all of the hardware, software, and sensory synchronization is perfect. To the extent that the person experiencing it believes they are actually there.

Why Do We Have Virtual Reality?

This may appear to be a great deal of work, and it is! What factors justify the development of virtual reality? The potential amusement value is evident. Films and video games that provide an immersive experience are examples. The entertainment sector is worth billions of dollars, and consumers are always interested in innovation. Virtual reality offers numerous more, more serious applications.

Virtual reality has a wide range of applications, which include:

  • Architecture
  • Athletics
  • Medicine
  • The Arts
  • Entertainment

Virtual reality can lead to innovative and interesting discoveries in various fields that have an impact on our daily lives.

When something in the actual world is too dangerous, costly, or impractical, virtual reality is the solution. Simulated reality enables trainee fighter pilots and medical applications trainee surgeons to take virtual risks in order to get real-world experience.

As the price of virtual reality decreases and it becomes more common, you may anticipate more significant applications, such as education and productivity, to emerge. Virtual reality and its cousin augmented reality has the potential to significantly alter how we interact with digital technologies. Humanizing our technologies will continue.


Features of Virtual Reality Systems

Virtual reality systems come in a wide variety, but they all have some things in common, like the ability to display content in three dimensions. The viewer is fooled into thinking the images are the actual size.

They also evolve in step with the shift in the observer’s visual field as they explore their surroundings. The goal is for the person’s head and eye movements to automatically trigger the desired reaction, such as a shift in perspective. This guarantees a satisfying and realistic virtual experience.

As a person navigates their virtual environment, they should receive timely, relevant feedback. When there is a lag between a user’s actions and the system’s response, known as latency, problems arise and the user’s experience is disrupted. Realizing they are in a simulation, the individual modifies their actions to fit the new context, leading to a robotic and stilted manner of communication.

The goal is to have the conversation flow easily and organically, creating a moment that will stick with the listener.

Final Words

Combining the ideas of “virtual” and “reality” produces the term “virtual reality.” It’s shorthand for a computer-generated, three-dimensional environment in which a user can freely move around and interact with objects.

Virtual reality (VR) is typically achieved through the use of computer technology. When hardware, software, and sensory modalities are perfectly in sync, a virtual reality experience can feel as real as being there. The evolution of virtual reality tools must account for the human form.

The fields of architecture, medicine, entertainment, and the arts are just some of the many that can benefit from virtual reality technology. Virtual reality is the answer when doing so in the real world would be too risky, expensive, or impractical.

Because of virtual reality technology, students learning to fly fighter planes and operate on patients using medical simulations can practice taking real-life risks without actually doing so. The way we interact with digital technologies may be fundamentally altered by virtual reality and its cousin augmented reality.
