What Exactly Is Virtual Reality?
Virtual Reality essentially portrays a three-dimensional, computer-generated environment that a person can explore or interact with. A person will become immersed in the virtual world and will be able to perform a series of actions and sometimes even be able to manipulate the objects present.
Consider this… You are looking at an astonishing Canaletto painting. You are experiencing the sounds and sights of Italy just like it was about 200 years back. You are fully immersed in your surroundings…” Virtual Reality could make this possible…
In order to experience fully immersive VR, you will need a head-mounted display (HMD), stereo sound, and sensory gloves so that you can feel your surroundings.
Criteria for non-immersive VR can be fulfilled by a highly realistic flight simulator on a home PC, particularly having a very large screen with headphones. It’s obviously not essential for everyone to use fully immersive VR, for instance, some may prefer to create a comprehensive 3D model of a new building that can be shown to the clients on a desktop by simply moving a mouse.
The best examples of collaborative VR are games such as ‘Second Life’ and ‘Minecraft’. Though these games meet the VR criteria, they fail to fully immerse us. Games such as these enable the user to share an experience in a virtual world with others.
How Does VR Work?
VR makes use of sensors in order to detect the movements of your body. It sometimes uses surround-sound speakers, multiple screens, and in some cases, haptic feedback i.e touch and body perception.
Here is the list of some VR devices:
Head Mounted Display (HMD)
HMD enables you to see a 3D image changing effortlessly, in real-time when you move your head. It consists of two small screens, one in front of each eye, stereo headphones and a blackout blindfold that prevents all other light, eliminating distractions from the real world. HMD’s also have built-in position sensors or accelerometers so they can identify how exactly your body or head is moving and accordingly adjust the picture you see.
A big part of the VR industry is to provide people with the ability to handle virtual objects. Datagloves contain sensors which are wired to the exterior of the gloves helping to identify motions of hand and body.
A VR wand is a ‘stick’ you use to point at, touch, or interact with a virtual world. It has built-in motion position sensors like accelerometers, along with scroll wheels and mouse-like buttons.
The healthcare industry is one of the biggest early adopters of virtual-reality. Virtual-reality simulations make use of medical images from ultrasounds and CAT scans to build 3D models of a the patient’s anatomy. These virtual models aid both experienced and new surgeons to determine the most efficient and safest method to place surgical incisions, locate tumours, or practice tricky procedures prior to the surgical operation.
Virtual Reality App Development has greatly contributed to enhancing the approaches of teaching and learning. Cerevrum and Unimersiv are the best examples VR apps that provide a huge resource of online educational VR content.
Museums have started to use VR to help tech people about history. Recently, the American Museum of Natural History in New York City has used VR for some of its collections that would be accessible through Google Cardboard. With a Smartphone, Google Cardboard and a VR headset visitors can now explore the museum and can have a immerse historic experience.
Car manufacturers have been utilising high-tech simulations for different purposes right from the design process to virtual prototypes. Ford Motor Company has integrated Virtual Reality within its automotive development using the ‘Oculus Rift’. The employees in Ford’s Immersion Lab in Michigan, can put on a virtual-reality headset and look over the design of a new car. They can also ‘sit’ inside the car prior to it is manufacturing.
Virtual-reality apps like ‘Live4buy’ are taking the concept of online shopping to the next level. Such VR apps facilitate a virtual tour of an entire store and perks up on the conventional online shopping experience. Shoppers can have a real-time shopping experience, instead of looking through catalogs on a website.
VR is a technology that has captured the attention of the tech world, even in it’s early developmental stages. It’s great aptitude of generating a virtual environment has made it worthwhile for many businesses and industries.
