Dynamic Field of View

About

One of the causes of VR sickness is the mismatch between our visual perception of the virtual environment (VE) and our vestibular system (a part of our inner ear allowing the perception of movement and balance).
Developers of the current VR technology attempts to combat it through improving the tracking systems. However, it only works when the user is not being moved inside VE (only their real world movement is projected in VE). When the user is supposed to be moving in-game, i.e. in a vehicle, or walk/run using the controller, the VR sickness symptoms will reappear.

Limiting the field of view (FOV) dynamically, can help reduce the VR sickness.This approach is used in many VR projects including the most popular ones, like Google Earth VR.

Usage
