LEGIBILITY OF SEGMENTED VERSUS STANDARD NUMERALS: A REVIEW,

Abstract

The literature review compares the legibility of segmented numerals and standard Arabic numerals. Based on present literature, the following conclusions are drawn. When compared to standard Arabics, segmented numerals are usually found to be less legible. However, of all the nonstandard numeral designs, segmented numerals are consistently superior. As the complexity of the observer's task increases, differences between the legibilities of segmented and standard numerals become insignificant. Therefore, no appreciable decrement in functional legibility is to be expected from segmented numerals in applied situations where tasks are typically complex. Practice effects, observers' motivation and stress, interaction of design types, number of segments and intersegmental distance are important variables to be considered. At present, little is known about how these variables influence legibility. Future research on legibility should be conducted under conditions which most nearly simulate the situation for which the proposed design is intended. (Author)
