Line 1:

[[FOV Reduction]], also sometimes referred to as '''Blinders''', '''Blinkers''', or '''Vignetting''', is a user interface feature some VR creators offer in their VR content. In an effort to reduce potential motion sickness, when the user performs certain in-game motion actions, such as turning, running, jumping, falling, ~~flying~~, etc, their [[FOV]] is automatically temporarily reduced. This may help reduce or prevent motion sickness.

'''Dynamic FOV Reduction''', also sometimes referred to as '''Blinders''', '''Blinkers''', or '''Vignetting''', is a user interface feature some VR creators offer in their VR content. In an effort to reduce potential motion sickness, when the user performs certain in-game motion actions, such as turning, running, jumping, falling, driving, etc, their [[Field of view|FOV]] is automatically temporarily reduced. This may help reduce or prevent motion sickness.

The user's view might be restricted to a small circle, or have black borders on the left and right, or the screen may be briefly blacked-out entirely.

In some VR content, this is a feature that can be turned on or off, or adjusted as to when or how often it will occur, and how significantly the [[FOV]] will be altered. Setting a FOV Reduction setting to a "strong" setting would mean that the user's FOV is significantly reduced when the reduction is triggered.
