The Validity of Subjective Reports of Visual Discomfort

Human Factors: The Journal of the Human Factors and Ergonomics Society, 1986
Many surveys comparing users of visual display units with non-users have evaluated discomfort with a single questionnaire, designed to determine the occurrence of various symptoms. These in reality elicit the person's opinion or recollection of their discomfort rather than its actual frequency or severity.

Discomfort and visual displays

Displays, 1985
Abstract The complaints of discomfort associated with the use of cathode ray tube displays are discussed from the perspective of a recent neurological theory of visual discomfort. It is concluded that stripes with a certain width, spacing and contrast can induce discomfort and various visual effects.

Visualizing the Perceived Discomfort of Stereoscopic Video

2012 IEEE International Symposium on Multimedia, 2012
Visual discomfort prediction is of importance for image safety issue in stereoscopic displays. This paper proposes automatic visualization of the perceived discomfort for stereoscopic video contents. The proposed method makes effective use of saliency-based measures for visual importance analysis in video scenes.

Visual discomfort prediction for stereo contents

SPIE Proceedings, 2011
The current renaissance of 3D movies has drawn more and more attention from the audience. Three-dimensional television (3DTV) has been expected to be the next advance in television. Studies have shown that different people have different comfort range of depth in a 3D content, especially in 3DTV scenario, wherein much smaller screen sizes and ...

The Effects of Visual Discomfort and Pattern Structure on Visual Search

Perception, 1998
Unpleasant somatic and perceptual side effects can be induced when viewing striped repetitive patterns, such as a square wave or a page of text. This sensitivity is greater in participants with higher scores on a scale of visual discomfort. In three experiments the effect that this sensitivity has on performance efficiency in a reading-like visual ...

Visual Discomfort and Visual Fatigue of Stereoscopic Displays: A Review

Journal of Imaging Science and Technology, 2009
Visual discomfort has been the subject of considerable research in relation to stereoscopic and autostereoscopic displays. In this paper, the importance of various causes and aspects of visual discomfort is clarified. When disparity values do not surpass a limit of 1°, which still provides sufficient range to allow satisfactory depth perception in ...

Discomfort Glare and Visual Performance

Transactions of the Illuminating Engineering Society, 1968
An experimental study was carried out to determine whether glare which had been scaled for discomfort would produce a decrement in visual performance. Three levels of glare and a no glare condition based on the IES glare index classification were established in a carefully controlled visual environment.

The eye, vision, and visual discomfort

Lighting Research & Technology, 1972
The eye, refractive errors and their significance and correction, accommodation and presbyopia, and the use of different types of multifocal lenses are first discussed. The functioning of the binocular visual system is considered, particularly in relation to efficient visual performance.
