Virtual reality (VR) is one of the hot new trends in tech. Virtual reality technologies are based on ideas that date back to the 1800s. The first stereoscope is said to be one of the oldest forms of VR. It was developed in 1838, and it used twin mirrors to project a single image. This stereoscope later evolved into the View-Master, which was patented in 1939 and is still produced to date.
The term “virtual reality” was initially used in the 1980s when Jaron Lanier, the founder of VPL research began developing the goggles, gear, and gloves needed to experience something he termed as “virtual reality.” However, before that, technologists were still developing simulated environments such as Morton Heilig’s Sensorama that was developed in 1956.
What is Virtual reality?
VR is an interactive computer-generated simulation of an environment or three-dimensional image that users can interact with, in an almost real or physical way. The artificial environments created are presented to users using specific electronic equipment such as gloves fitted with sensors. VR primarily uses auditory and visual senses, but it also allows other sensory feedback such as haptic.
Is VR similar to Augmented Reality and Mixed Reality?
VR reality is not the same as Augmented Reality or Mixed Reality.
Augmented Reality (AR) uses the camera of a phone or smart device and adds digital elements to a live view. The Snapchat lenses are an excellent example of AR. Mixed Reality (MR), on the other hand, is a technology that combines AR and VR.
How does Virtual Reality work?
VR primarily works by simulating one’s vision and tricking the brain to think that is in the real world. VR headsets create an immersive 3D environment by placing a screen with two lenses (one for each eye) in front of user’s eyes. This screen eliminates all interaction with the real world. The two-autofocused lenses placed between the screens adjust based on eye movement and positioning.
VR screens use stereoscopic display to bring out two slightly different angles to the scene of every eye. These two angles simulate depth, making the environment seem more real. VR also uses other techniques such as parallax and shading to create depth. The visuals on the screen of a VR kit are rendered using a phone or HDMI cable connected to a computer.
For total immersion, a VR screen has to meet these prerequisites:
- A frame rate minimum of 60 frames per second
- 100 degree minimum Field of View
- A refresh rate of 60 frames per second minimum to avoid causing motion sickness
If the kit does not meet these requirements, users will experience latency. VR kits are required to have a response of fewer than 20 milliseconds to trick the brain into believing simulations. This can only be achieved by combining the factors above in the right proportion. Do you have a VR it? How do you protect yourself from the increasing privacy issues and identity theft? By using tools such as virtual VPN router, you can ensure safety as you play.
