Field of View (FOV) in VR refers to the extent of the virtual environment that a user can see while wearing a VR headset. It is an essential aspect of the VR experience as it determines how much of the virtual world the user can take in at one glance, and how immersive the experience will be. It is measured in degrees, and it typically ranges from 90 to 120 degrees in most VR headsets. However, some high-end VR headsets have a wider field of view, which can reach up to 200 degrees, providing a more immersive experience.
A larger field of view allows the user to see more of the virtual environment at once, making the experience more realistic, and providing a greater sense of immersion. On the other hand, a smaller field of view can lead to a sense of tunnel vision, making the experience less immersive, and less realistic.
It’s important to note that the field of view is not only determined by the VR headset but also depends on other factors such as the resolution and size of the display, the distance between the lenses and the eyes, and the distance between the user and the screen. With advancements in VR technology, VR headset manufacturers are working on increasing the field of view to provide more immersive experiences for users.
