"Conventional human engineering legibility specifications for alphanumeric symbology displayed on video monitors consist f predictors of user performance derived from legibility research studies. Typical legibility predictors are symbol size, symbol luminance, contrast ratio, font, dot matrix dimensions, and pixel active area. This report discusses a number of significant problems associated with the development and application of conventional legibility specifications"--Abstract, page 2. Optical character recognition.
