Variables Influencing the Perception of Flicker in Wide Angle CRT Displays.

Abstract

An experiment was conducted to determine the influence of several variables on the perception of the psychophysical phenomenon of flicker in wide angle CRT displays. Three independent variables were 3, 6, and 9 FL illumination levels, of which there were four images, three static and one dynamic; 26 fixation points were positioned around a display from 0 to 120 deg in the horizontal axis and 60 deg down to 90 deg up in the vertical axis. Recorded measures in the factorial experiment consisted of time to the first observation of flicker, percentage of the total number of trials that flicker was observed, and the severity of flicker regarding its interference with a visual task. Analysis of variance tests were applied to the experimental data. (Modified author abstract)
