BackgroundDiscomfort evoked by stereoscopic depth has been widely concerned. Previous studies have proposed a comfortable disparity range and considered that disparities exceed this range would cause visual discomfort. Brain activity recordings including Electroencephalograph (EEG) monitoring enable better understanding of perceptual and cognitive processes related to stereo depth-induced visual comfort.MethodsEEG data was collected using a stereo-visual evoked potential (VEP) test system by… 

Neural Research on Depth Perception and Stereoscopic Visual Fatigue in Virtual Reality

Virtual reality (VR) technology provides highly immersive depth perception experiences; nevertheless, stereoscopic visual fatigue (SVF) has become an important factor currently hindering the

Research on the effect of contrast enhancement and illumination condition on 3D visual fatigue

3D visual comfort can be influenced by such common factors as binocular parallax, 3D image contrast, viewing distance, and illumination condition. This paper investigates the effect of contrast

Visual Discomfort and Visual Fatigue of Stereoscopic Displays: A Review

TLDR
The importance of various causes and aspects of visual discomfort is clarified and three-dimensional artifacts resulting from insufficient depth information in the incoming data signal yielding spatial and temporal inconsistencies are believed to be the most pertinent.

The zone of comfort: Predicting visual discomfort with stereo displays.

TLDR
This work focused on how vergence-accommodation conflicts in stereo displays affect visual discomfort and fatigue, and found that negative conflicts are less comfortable at far distances and that positive conflicts are more comfortable at near distances.

Towards a Physiology-Based Measure of Visual Discomfort: Brain Activity Measurement While Viewing Stereoscopic Images With Different Screen Disparities

TLDR
The results of the fMRI experiments suggest that visual discomfort due to excessive screen disparities can be caused by sensory and/or motor phenomena and the intraparietal sulcus (IPS) regions in the human brain may be involved in the sensory phenomenon.

EEG-Based Assessment of Stereoscopic 3D Visual Fatigue Caused by Vergence-Accommodation Conflict

Recent advances in 3D displays have contributed to the pressing need of new measurement methods for display comfort. Developing a valid measurement of visual fatigue caused by 3D display remains a

Assessing the zone of comfort in stereoscopic displays using EEG

TLDR
An experimental protocol is described which compares two different comfort conditions using electroencephalography (EEG) over short viewing sequences, which showed significant differences both in event-related potentials (ERP) and in frequency bands power.

EEG based evaluation of stereoscopic 3D displays for viewer discomfort

TLDR
3D passive polarized technology provides more comfortable visualization than 3D active shutter technology and 3D viewing is more attractive than 2D due to stereopsis which may cause of high attention and involvement of working memory manipulations.

Preliminary Study on EEG-Based Analysis of Discomfort Caused by Watching 3D Images

The objective here is to investigate the effects of 3D images on viewers, study the relationship between power spectrum features of EEG and discomfort of the viewers, and try to figure out an

TLDR
This paper quantified viewer discomfort by measuring eye blinking rates using an eye tracker system, and estimated the user's eyestrain by integrating theEye blinking rates with user's subjective test responses when watching stereoscopic 3D content in relation to binocular disparity, viewing time and display size.
