Information Transfer from Computer-Generated Dot-Matrix Displays.

Abstract

This report summarizes a research program which has investigated the effects of numerous design parameters of alphanumeric dot-matrix displays upon operator performance. Among the parameters investigated experimentally are dot size, dot shape, dot contrast (or modulation), dot spacing, matrix size, character size, word context, ambient illuminance, character (dot) luminance, and character font. Operator performance in reading and search tasks was predicted by a linear regression model and subsequently cross-validated by additional experiments. Evaluations of several specific flat panel displays were made, with operator performance predicted acceptably from the previously derived regression model of display quality. Optimal capital alphanumeric fonts were determined for 5 x 7, 7 x 9, and 9 x 11 matrices. (Author)
