Operator performance as a function of line and cell failures on a flat panel display

Abstract

The effects of manipulating discrete element failure types and font types were determined on a reading performance task using a plasma panel display. Thirty male and thirty female college students attending Virginia Polytechnic Institute and State University participated as subjects. The results demonstrate that reading performance is significantly degraded by the random addition or removal of discrete elements or lines of elements. Subjects took longer to read and made more null responses with lower case characters than with upper case characters. Similarly, reading performance was poorer in the discrete element failure condition than in the horizontal line or vertical line failure conditions. The Huddleston font was found to be better than the Lincoln/Mitre and the font used on the HP2621A.
