How does the field of view affect VR video clarity?
The field of view (FOV) of a VR headset can have a significant impact on the clarity of VR videos. The human eye has a wide field of view, and when viewing a VR video, the eye is sensitive to distortions and aberrations at the edges of the field of view. If the FOV of the VR headset is too narrow, the image may appear distorted or blurry, particularly at the edges. Additionally, if the FOV is too wide, the image may appear stretched or distorted, which can also affect clarity. To address these challenges, VR headset manufacturers are working to develop headsets with wider FOVs, as well as more advanced optics and rendering technologies to minimize distortions and aberrations.
The ideal FOV for VR headsets is still a topic of debate, but most experts agree that a FOV of at least 100 degrees is required to provide an immersive and engaging VR experience.
