Want to know, How does VR actually works? then In this post, we will explain you How does VR work.

How does VR work- working of VR\

VR working procedure


VR requires multiple devices such as a headset, computer / smartphone or other device to create a digital environment, and a device to track motion in some cases. Typically, a headset displays content in front of the user's eyes, while a cable (HDMI) transfers images to the screen from a PC. Another option is headsets that work with smartphones, such as Google Cardboard and GearVR - a phone that acts as a display and source of VR content.


Some retailers use lenses to transform three-dimensional images. Typically, a 100/110-degree visual field is available for VR devices. The next key feature is the frame rate per second, which should be at least 60 fps to make the visual comparison seem more realistic.

Complete procedure of VR working-


Head tracking-

The head tracking system on VR headsets follows the movement of your head towards the sides and angles. It provides an X, Y, Z axis for navigation and movement, and includes tools such as an accelerometer, gyroscope, LED circle (around the headset to enable an external camera). Head tracking requires a minimum delay, i.e. 50 milliseconds or less, otherwise, users will notice a slip between head movement and simulation.


Eye tracking-

Some headsets contain an eye controller that traces your eyes within the visible area. The great advantage of this technology is finding a realistic and in-depth viewing field.


Tracking-

Although not yet fully developed and operational yet, movement tracking can elevate VR to a whole new level. The thing is, without following the footsteps you will be limited to VR - you can look around and navigate. Using 6DoF (six degrees of freedom) concepts and 3D space, the motion support support options fall into 2 groups, visual tracking and light use. Visual tracking is usually a camera on the headset to track movement, while non-optical means the use of other sensors in the device or body. Most existing devices actually include both options.
