This discussion of factors involved in the presentation of text, numeric data, and/or visuals using video display devices describes in some detail the following types of presentation: (1) visual displays, with attention to additive color combination; measurements, including luminance, radiance, brightness, and lightness; and standards, with specific comparisons between Swedish and U.S. standards for visual display units; (2) color description systems, including the Munsell System, the Natural Colour System (NCS), the hue-lightness-saturation system (HLS), the hue-value-saturation system (HVS), and the red/green/blue (RGB) system; (3) text systems, including characters, design, background, and context; (4) numeric data, with attention to computer graphics hardware and software; and (5) visuals that depend largely on the quality of the screen, e.g., pie charts. The need for additional research in several areas is noted, and a 16-item bibliography is provided. (THC)
