A COMPARISON OF TWO PROPOSED LOGIC SYMBOL TYPE5 FOR LEGIBILITY AND READABILITY DIFFERENCES
Abstract
Two proposed logic symbol types were compared for legibility and readability differences. One symbol type, Shaped Symbols, used shaped forms to differentiate basic logical functions. The other symbol type, Block Symbols, utilized a specified alphabetic character inclosed within a defined area to denote logical functions. An unpublished legibility study was replicated and the results of both studies agreed. This agreement was largely attributed to constant, uncontrolled variables in both studies. A readability evaluation was conducted to functionally compare the two symbol types. The results tended to favor the use of Shape encoded symbols in situations where problem solving of functional and logical relationships, in the context of other essential information, is of prime concern and density of symbols is high.
