Virtual Reality Technology and it’s Applications

Virtual reality

Virtual reality (VR) is an experience taking place within simulated and immersive environments that can be similar to or completely different from the real world. Virtual reality has had the meaning of “being something in essence or effect, though not actually or in fact” since the mid-1400s.

As a kid, I wanted to do a lot of things as we all did. So, I dream of becoming an Astronaut, go to the mars, or become a Pilot, at one point I wanted to become a Cricketer and represent my country, There was also a time I thought of joining the army or work in the film Industry.

In childhood, we all had such dreams but when we grew up we realize we can’t do everything. But if Virtual reality ever lives up to its promise, you might be able to do all these things and many more without even leaving your home.

Applications of Virtual reality include Gaming, movies, Education purposes. Apart from games and entertainment, it can also be used for training airline pilots and surgeons for complex problems. So, how does it actually work, let’s look at it?

Software

The Virtual Reality Modelling Language (VRML), first introduced in 1994, was intended for the development of “virtual worlds”. The Web3D consortium was subsequently founded in 1997 for the development of industry standards for web-based 3D graphics.

The consortium subsequently developed X3D from the VRML framework as an archival, open-source standard for web-based distribution of VR content. WebVR is an experimental JavaScript application programming interface (API) that provides support for various virtual reality devices, such as the HTC Vive, Oculus Rift, Google Cardboard or OSVR, in a web browser.

Hardware

Modern VR headset displays are based on technology developed for smartphones including gyroscopes and motion sensors for tracking head. Small HD screens for stereoscopic displays; and small, lightweight and fast computer processors. These components led to relative affordability for independent VR developers.

Independent production of VR images and video has increased by the development of omnidirectional cameras, also known as 360-degree cameras or VR cameras. To create a feeling of immersion, special output devices are needed to display virtual worlds.

Special input devices are required for interaction with the virtual world. These include the 3D mouse, the wired glove, motion controllers, and optical tracking sensors.

Applications or Uses of Virtual Reality

Virtual reality Military

  • One of the Areas where VR has been adopted is in the Military. Today, the number of VR projects for the military is increasing, and by 2025 it is even expected to generate a significant $1.4 billion in revenues.
  • About 1 in 20 deaths of Soldiers happen during the training. In order to solve this problem Virtual reality was introduced. VR provides immersive training to the soldiers which seem like real life combat.
  • They can simulate different kinds of battlefield scenarios. All the scenarios include flight simulation, medical administration in the battlefield, virtual boot camps and several other scenarios.
  • Since most VR training is a game like soldiers finds them quite enjoyable.

Virtual reality Cinemas

  • Since the Lumiere brothers showed the first film in Paris in 1895, cinema has made our lives quite entertaining. Cinema to me is the most immersive form of storytelling and combine that with virtual reality, magic is bound to happen.
  • A lot of cinemas have adopted VR technology nowadays. They distribute head-mounted display units to all viewers for each movie. 
  • With the VR technology becoming better each day, the movie-going audience has something awesome to look forward to.

Medical field

  • When we think of VR, we tend to associate it with entertainment. But VR has also made significant improvements in the lives of people with autism, lazy eye, chronic pain, and other health problems.
  • Surgeons now make use of virtual reality to figure out all the positions of unwanted tumors in the body of their patients. This will enable them to determine the best incision positions to be able to remove the tumors without any form of complications. It presents every part of the human body as clearly as possible. 
  • Virtual reality is now used for robotic surgery where robots perform surgeries under the control of surgeons. This increases speed, accuracy, and effectiveness of surgery processes and it also gives the surgeon some form of convenience as they won’t be the one to perform the task.

Work Collaboration in the workplace

  • Some companies have embraced virtual sharing to allow personnel to collaborate on assignments without relocating to one physical location. For example, where a company has remote workers from different geographical locations, it is necessary that they coordinate and complete tasks on time.
  • Since teamwork is essential for a company’s success, VR technology makes it possible for workers to hold meetings through video conferencing. With this technology, employees can gather in the same room and consult without meeting face to face.

Education

  • Virtual reality (VR) has entered the world of education through the big door creating new resources to teach and learn.
  • It improves teaching and learning. With virtual reality, a large group of students can interact with one another within a 3-dimensional environment.
  • Students can witness what happened in history in the first person, go deep into the human body and experience new learning experiences from a different point of view. 
  • Students can also use virtual reality to learn about the careers that may be of their interest, to have a better professional orientation that allows them to better decide their future.
  • It also makes learning fun for students.

Conclusion

In the end, Virtual reality (VR) technology is a quite exiting. It’s going to make our lives better in many different ways. We are still quite far to fully crack it but when we do it’s going to be a boon for the market.
