VISUAL SIGNAL DETECTION AS A FUNCTION OF THE SPATIAL DISTRIBUTION AND THE SIZE OF DISPLAYED ELEMENTS,

Abstract

The report describes several experiments which investigated the luminance thresholds for signal recognition as a function of the spatial frequency and size of displayed elements on a television monitor. These factors were varied to simulate the perceptual conditions that occur when line scan displays are viewed at slant angles to enhance signal recognition. Several exploratory studies were conducted to determine if viewing the line scan display at a slant angle and if providing a dynamic control of the raster size enhanced signal recognition. (Author)
