Virtual reality sickness may have undesirable consequences beyond the sickness itself. For example, Crowley (1987) argued that flight simulator sickness could discourage pilots from using flight simulators, reduce the efficiency of training through distraction and the encouragement of adaptive behaviors that are unfavorable for performance, compromise ground safety or flight safety when sick ...
An increase in vergence-accommodation conflict [2] occurs as the eye changes its movement patterns to focus on the position of objects recreated by stereoscopy. [3] One may counter vergence-accommodation conflict when seeing a 3D movie or using a near-eye display system (e.g., augmented reality (AR) and virtual reality (VR) ) adapting ...
This commonly occurs in virtual reality devices, augmented reality devices, 3D movies, and other types of stereoscopic displays and autostereoscopic displays. The effect can be unpleasant and cause eye strain. Two main ocular responses can be distinguished: vergence of eyes, and accommodation. Both of these mechanisms are crucial in ...
Motion sickness due to virtual reality is very similar to simulation sickness and motion sickness due to films. [19] In virtual reality the effect is made more acute as all external reference points are blocked from vision, the simulated images are three-dimensional and in some cases stereo sound that may also give a sense of motion.
Stereoblindness (also stereo blindness) is the inability to see in 3D using stereopsis, or stereo vision, resulting in an inability to perceive stereoscopic depth by combining and comparing images from the two eyes. Individuals with only one functioning eye have this condition by definition since the visual input of the second eye does not exist.
Foveated rendering is a rendering technique which uses an eye tracker integrated with a virtual reality headset to reduce the rendering workload by greatly reducing the image quality in the peripheral vision (outside of the zone gazed by the fovea).
Virtual reality (VR) is a simulated experience that employs 3D near-eye displays and pose tracking to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games ), education (such as medical, safety or military training) and business (such as virtual meetings).
In the context of human and primate vision, the term "field of view" is typically only used in the sense of a restriction to what is visible by external apparatus, like when wearing spectacles [1] or virtual reality goggles. Note that eye movements are allowed in the definition but do not change the field of view when understood this way.
