How does Virtual Reality Headsets for PC Work ?
The headset set-up is being used by Microsoft, Oculus, Google, Sony, HTC and Samsung and requires three things:

  • PC, a console or a mobile device to run the app or game
  • A headset which secures a display in front of your 
  • Inputs such as head tracking, controllers, hand tracking, trackpads or other 

Most VR headsets for PC are referred to as HMD for Head Mounted Displays. Even with no audio, trackpads or hand tracking, you can experience Virtual Reality with the Google Cardboard (you simply place your smartphone inside the Googlr Cardboard and you display it in front of your). The Game or Video is sent from the console, PC or Laptop to the headset via a HDMI cable. For Google Cardboard and other VR heasets for smartphones, it's already on the mobile device/headset. Virtual Reality headsets use either two feeds sent to one display or two LCD displays (one per eye). There are also lenses which are placed between the eyes and that can be adjusted to match the distance between eyes (the distance called PD varies from person to person). 

One important way VR headsets can increase immersion is to increase the field of view and the most popular VR headsets for PC makes 100 or 110 degree field of view and a minimum frame rate (FRS) of around 60 frames per second is needed to avoid users feeling sick. For example, the Oculus headset is capable of 90 Frame Rate per Second and other VR are as much as 120 FPS. 

Head tracking

Head tracking means that when the user’s wear a Virtual Reality headset, the picture in front shifts as the user look up, down and side to side or angle his head. Head tracking is also one big advantage that VR headsets for PC have over the Google Cardboard headset or other Headsets for smartphones.

Motion tracking
These can detect the precise position of your head and your hands based on the timing of when they hit each sensor on the headset and or around the handheld controllers. 

Eye tracking 
Eye tracking is also another important component of Virtual Reality but it is not available on all Headsets. In short, there is an infrared sensor that monitors your eyes inside the virtual reality headset so the headset knows where the eyes of the user or gamer are looking in virtual reality. It makes the depth of field very realistic. Without eye tracking and with everything in focus as you move your eyes  around a scene, the feeling of sickness is more likely.
