Effects of Illumination and Viewing Angle on the Modeling of Flicker Perception in CRT Displays
… as part of a new ANSI/HFES 100 standard for CRT flicker. A graph based flicker prediction method developed from Farrell, 1987 was evaluated. The Farrell model is based on phosphor persistence, screen luminance, display size, and viewing distance. The graph based method assumes a worse case …

Subjective Image Quality of CRT Displays under Ambient Glare: Assessing the ISO 9241-7 Ergonomic Technical Standard
… judgments by viewing alphanumeric text on the CRT screens. Subjective scale values also were correlated with ISO classifications and two ISO metrics: screen image luminance ratio (Diffuse, 200 lux) and specular reflection image luminance ratio. The ANOVA findings indicated that specular glare …

Objective Image Quality of CRT Displays under Ambient Glare: Assessing the ISO 9241-7 Ergonomic Technical Standard
This thesis assessed the readability of CRT displays viewed under ambient lighting conditions and then evaluated the findings with respect to the ISO 9241-7 standard. More specifically, two phases of work were conducted in this thesis. In Phase 1, seven monitors were evaluated photometrically …

Effects of illuminance, luminance, viewing angle, and screen test pattern on the perception of flicker in CRT displays
… angle affect the perception of flicker in a CRT, especially in relation to the flicker evaluation method in the ANSI/HFS 100-1988 standard. Twenty participants viewed a CRT at different viewing angles, under different levels of illuminance and luminance, and with different screen test …

The effects of image quality on reading performance and perceived image quality from CRT and hard-copy displays
… on reading and on perceived image quality from CRT and hard copy were studied in this experiment. The results showed that as the image quality of a display increased, indicated by an increase in the value of the MTFA, the reading speed increased and subjective image quality V; ratings increased. …

Effects of color CRT misconvergence, target size, and nontarget density on visual search performance
… decade have led to the widespread use of color CRT displays. misconvergence among the primary colors of a shadow-mask CRT is a principle human factors concern for applications of this technology. The major objectives of this research were: (1) to determine the effect of misconvergence on visual …

Effects of color CRT misconvergence and font type on text readability and subjective preference
… society relies on the widespread use of color CRT displays. Misconvergence of the primary colors of a shadow-mask CRT is a problem with this technology that deserves human factors engineering consideration. The purpose of this research was as follows: (1) to determine the effects of …

Effects of retinal disparity depth cues on cognitive workload in 3-D displays
… the use of field-sequential stereoscopic CRT displays. The usefulness of stereopsis to present depth information has been studied in terms of performance measures such as search time, search accuracy, and subjective image quality ratings. Few, if any, studies have been conducted to …

An Investigation of Color Memory as a Function of Hue, Saturation, Lightness and Observer Imagery Vividness for Blue, Green and Orange Test Hues
Fifty-two college-aged observers participated in an experiment assessing color memory via a PowerPoint '97 computer display program which varied one of the three dimensions of hue, saturation and lightness at a time. Consistent with previous research, errors were greater for the lightness …
