You will probably never go to Mars, swim with the sharks, run an Olympic 100 meters, or sing onstage with your favourite singer. Virtual reality (VR) might be able to let you do all these things without even leaving your home.
What is Virtual Reality?
VR means experiencing things through our computers that don’t really exist. It simulates our world using high-performance computers and sensory equipment, like headsets and gloves. VR makes you think you are actually living inside a completely believable virtual world. It is two-way interactive: as you respond to what you see, what you see responds to you.
Types of Virtual Reality
- Fully immersive
For the complete VR experience, we need three things.
- A computer model or simulation
- A powerful computer that can detect what we’re going and adjust our experience accordingly in real time
- Hardware linked to the computer that fully immerses us in the virtual world as we roam around.
A highly realistic flight simulator on a home PC might qualify as non-immersive virtual reality, especially if it uses a very wide screen, with headphones or surround sound, and a realistic joystick and other controls.
The idea of sharing an experience in a virtual world with other people, often in real time or something very close to it. Collaboration and sharing are likely to become increasingly important features of VR in future.
What Equipment Are Required For Virtual Reality?
Head-mounted displays (HMDs)
HMDs enable you to see a 3D image that changes smoothly, in real-time, as you move your head. It looks like a welding visor with two small screens in front of your eyes. HMDs usually have built-in accelerometers or position sensors so they can detect exactly how your head and body are moving and adjust the picture accordingly.
An alternative to putting on an HMD is to sit or stand inside a room onto whose walls changing images are projected from outside. As you move in the room, the images change accordingly. Flight simulators use this technique, often with images of landscapes, cities and airport approaches projected onto large screens positioned just outside a mockup of a cockpit.
You will touch or reach out to it when you see something amazing. It’s a natural instinct of human. Data gloves let you touch the objects seen in the virtual world. They are gloves with sensors wired to the outside to detect hand and figure motions.
A wand is a stick used to touch, point or interact with a virtual world. It has position or motion sensors built in, along with mouse-like buttons or scroll wheels.
VR is interesting, right? Many game and entertainment companies are developing related products that adopt the concept of VR. Some retailers integrate VR into shopping to create a more amazing shopping experience for shoppers. What more intriguing is the adoption of VR in funeral services to enable customers to preview the decorations of the funeral ceremony. VR will be everywhere in the future, by then, we will be living in two worlds – the real and the virtual world.
