Beginners Guide To VR

VR, short for virtual reality, allows people to be fully immersed in a fabricated environment. This is usually (but not always) delivered through head-mounted hardware that tracks a person’s movements. These VR headsets consist of a screen (or two display panels, one for each eye) housed in a frame (or headset) strapped or fitted to your head.

A pair of lenses is usually placed between the panel and your eye, blocking out the outside world, making it seem like what you see through the headphones is your whole world.

The PSVR prescription lenses is one of the best lenses for VR adopters.

Terminology and basic concepts:

Field of view (field of view)

The FOV is shortened beyond the field of view. In the context of our eyes, our field of vision is all that you can see at any time.

In the context of headphone VR, the field of view describes everything that you can see in the virtual world at any time while using the headphones.

Degrees of freedom

When it comes to movement and tracking in VR, people often talk about "degrees of freedom" or DoF. More degrees of freedom means more of your physical movements are captured by the headphones and mapped to your performance simulation.

Tracking type

Every VR headset needs a way to track the movements of the people wearing the system. The most common form of tracking today is known as inside-out tracking. These systems are usually based on a camera built into the headphones to track movement from the inside of the headset to the outside.

Controller

There are several ways to interact with simulated content. Headphones like the Oculus Quest 2, HP Reverb G2 and HTC Vive Cosmos are available with two controllers, one for each hand, which are also tracked in 6DoF with an inside-out tracking system.
