Virtual Reality is turning into a really in demand idea and with such a large amount of new devices and cameras that have to begin showcasing this technology, it is straightforward to feel left behind. As a result of VR remains comparatively new it’s going to not even be one thing that you just have full-fledged nonetheless. Virtual reality (VR) actually means that we can experience things through our computers that don’t really exist in the real world. From that simple definition, the idea doesn’t sound especially new. When you look at an amazing painting, for example, you’re experiencing the sights and sounds of Italy as it was about 250 years ago—so that’s a kind of virtual reality. Same way, if you listen to instrumental or classical music with your eyes closed, and start imagining things, isn’t that an example of virtual reality—an experience of a world that doesn’t really exist? What about losing you in a book or a movie? Surely that’s a kind of virtual reality?
If you need to understand why books, movies, paintings, and pieces of music aren’t the same thing as virtual reality, we need to define VR fairly clearly. For the purposes of this simple, introductory blog, we are going to define it as:
“A believable, interactive 3D computer-created world that you can explore so you feel you really are there, both mentally and physically.”
Putting it another way, virtual reality is essential:
Believable: You really need to feel like you’re in your virtual world (on Mars, or wherever) and to keep believing that or the illusion of virtual reality will disappear.
Communal: As you roam around different places, the VR world needs to coordinate with the movements of yours. You can watch a 3D movie and be transported up to the Moon or down to the seabed—but it’s not interactive in any sense.
Computer-generated: Why is that important? Because only powerful machines, with realistic 3D computer graphics, are fast enough to make believable, interactive, alternative worlds that change in real-time as we move around them.
Explorable: A VR world needs to be big and detailed enough for you to explore. However realistic painting is, it shows only one scene, from one perspective. A book can describe a vast and complex “virtual world,” but you can only really explore it in a linear way, exactly as the author describes it.
In the context of present-day VR head-mounted displays (HMDs; these are those box-shaped gadgets you wear on your head), it is predominantly our senses of sight and hearing that is being fed computer-simulated data. Either through 3D modeled environments or 360-degree recordings of real-world locations, VR HMDs help transport the user to an entirely new location, completely blocking out the real world in the process. The more realistic the images and audio fed to the user, the more convincing is the illusion – the more the user feels like she is actually “immersed” or “present” in this new world.
In the Jurassic World VR demo on the Samsung Gear VR ‑ as the dinosaur stands up, you truly understand how small you are compared to it and when it leans down and breathes into your face, your lizard brain coils back in fright. These are sensations that were impossible to experience before the advent of VR.
Of course, once you realize the true potential of VR, your mind begins to race with the possibilities that have now opened up. You imagine its applications in tourism, education, gaming, social networks, etc.
Types of Virtual Reality:
Virtual reality has now often been used as a most compelling market buzzword, video games which are interactive or even movies that are 3D and different television programs, and you know that none of which really counts as virtual reality because they don’t immerse you either partially or even fully in a virtual world. Search on your own for “virtual reality” in your mobile phones apps store and you’ll find hundreds of similar apps, even though you also know it that your mobile phone screen could never get anywhere near producing the convincing experience of VR. And things like interactive gaming and computer would certainly meet certain parts of our definition given above, so definitely there’s clearly more than one approach to build virtual worlds and more than one type of virtual reality. Here are a few of the variations of Virtual Reality:
Fully immersive: For any fully VR experience, we basically need three things. First, a richly designed and detailed virtual world so that we can explore; in other words a computer or a simulation. Secondly, a powerful machine/system that can detect what we’re going to do and adjust itself according to our experiences in real time (like what we hear or see must change according to our movements—just like in real reality). Third, and most importantly hardware linked to the computer that fully leads us in the virtual world as we wander around. Usually, these kinds of experiences can be discovered by putting off what’s called a head-mounted display (HMD) with stereo sound and two screens. Or we could just move around inside a room, fitted with surround-sound streaming speakers, onto which movable images are projected from outside.
Non-immersive: A very high realistic bus or train simulator on a home system usually qualifies as non-immersive virtual reality, especially if there is a usage of a very wide screen, with surround sound, and a joystick and other controllers. Not everyone in our surrounding wants or needs a virtual reality like for an example an architect might need to build a detailed 3D model of a new building to show to clients that can only be explored on a computer system by moving a mouse or handling different controllers. And till many people would classify this as a kind of virtual reality and you know it because it doesn’t fully lead to a virtual world. Archeologists-they doesn’t actually take you back to hundreds or thousands of years or create the smells, and tastes of the history, but they give a much detailed experience through virtual reality than a few pastel drawings or even an animated movie.
Augmented Reality: Devices like our smartphones and Laptops have put what used to be supercomputer power in our pockets and hands. If we’re roaming around the world, maybe visiting great and historic monuments or heritage site or a fascinating foreign city we’ve never been to before, then everyone wants is actually not virtual reality but an enhanced experience of the reality we can see in front of us. That’s procreated the idea of augmented reality (AR), where, for example, you just point your cell phones at a landmark or a historic building and interesting information about it pops up on your screen automatically. AR (Augmented reality) is all about connecting and immersing the real-world experience to the virtual world of information that we’ve created on the Web. We know that neither of these worlds is virtual, but the idea of exploring and roaming the two simultaneously does, but still, they have things in common with virtual reality. For example, how do the things you see on the smartphones screens changes as you wander around a city? Technically, we can say that there are some definite links between Virtual Reality and Augmented Reality.
Virtual reality is a trending technology based on the basic idea of immersing into reality artificially and not naturally. Finally, VR becomes a reality but to this technology, there are some Pros and Cons of it. Some of the main pros and cons are listed below:
Pros of Virtual Reality:
Better than reality: Visuals seen in virtual reality are far better than real experiences. Virtual reality technology is now being used in video games and the user gets a feeling that he is actually being transferred to another world. In video games by the game controller which is a VR tech transmits the vibrations and also other sensations to the user. The use of ambient sounds and graphics in video games has been incorporated into reality. Moreover, it gives a good gaming experience to the user. Also, users can also get real experiences in gaming such as user fighting with zombies.
Used in various fields: Due to its extensive features, virtual reality has been used in different fields such as in the military, education, and healthcare. It helps in adding more dimensions in various fields. Virtual reality used in aviation and architecture for viewing the final product.
Users have awesome experiences: The audience has exceptional experiences in using virtual reality. The VR technology makes the audience feel that they experience the real locations and hearing the real sounds and seeing the real things. Many people have the feeling to use more and more virtual reality technology. It can be used by disabled people. Because using virtual reality they can explore the real world. Films which are produced for VR gives permission to the audience to view the whole surroundings in each and every scene. Thus, it creates an immersive viewing experience for the audiences.
Gives detail views: Virtual reality helps you giving a full and detailed view of a place. For example, virtual reality makes tourism sites more attractive and easy. And as we discussed earlier, It gives the detailed view of a place where you want to visit. So that audience can plan their trip by seeing the real locations of that place. Moreover, users can also see the important landmarks, heritage sites as well important places in which they are interested to go.
Cons of Virtual Reality:
High cost: One of the main cons of VR (Virtual Reality) is that it’s not possible for everyone to afford it. It is too costly and users who cannot afford these will be left out from using this technology.
Communication should not be replaced by a group of people: Another major disadvantage of virtual reality is that communication using this technology should not be replaced with a group of people. Moreover, they would be vulnerable to lying.
Feeling of worthlessness: The actual users or audience of virtual reality many times get a feeling of worthlessness. They feel that they are actually escaping from the real world and responsibilities this further feeling is proved to be very dangerous for them.
Users addict to the virtual world: The users get addicted to the virtual world and drift away from the non-virtual environment. This addiction can cause various health issues to them in the long term.
Technology is still experimental: Though the virtual reality technology is used in various fields but is still experimental. It is not being accepted or fully developed. And like any other technology, VR also has many cons due to which it is not acceptable fully.
Particularly in the above blog, we have directed you the points where you can well imagine the different fields where it can be used for practical purposes but on the other hand, its erroneous use can be dangerous for us. Apart from all that this, as the technology is increasing its pace, VR is the result of that and definitely, it will be a powerful weapon in this era of techs and gadgets.
