Studies of Display Symbol Legibility: Xxi. the Relative Legibility of Symbols Formed from Matrices of Dots
نویسندگان
چکیده
The purpose of this study was to determine the legibility of symbols formed from matrices which contained different numbers of dot elements. A set of alphanumeric symbols was constructed from each of the following dot matrices: 3x5, 5x7, 7x 11, and 9 x 15. The four symbol, sets were shown for identification to one group of operators under nearly optimal viewing conditions and to a second group under degraded viewing conditions. Both rate and accuracy of identification were recorded. The results indicate that the 5x7 symbols are as legible as 7 x 11 and 9 x 15 symbols for most of the conditions studied, but in one condition the 7 x 11 was more legible than the 5x7,

This report describes the findings of a study in symbol legibility which investigated the reading time and errors for common five-letter words when they are projected by a solid stroke and when they are shown by a broken stroke. The latter was produced on a 945-line TV monitor at 10, 7, and 5 active lines per symbol height. This study is similar to an earlier report on the readability of common...

Introduction Symbol (i.e., "pictorial") highway signs yield legibility distances which are on average twice as great as those achieved for their text sign counterparts. However, the relative superiority of symbol signs is neither uniform nor universal. Some symbol signs are legible from 3-times as far away while other poorly designed symbol signs can be recognized at only half the distance of t...
