Using Digital Image Elements To Produce Schematic Pictures (original) (raw)

There are two categories of representations: figurative and non-figurative. Within the category of figurative representations, there are two groups: visuals and graphic symbols. Graphic symbols include pictorial symbols, abstract symbols, and arbitrary symbols. Symbols can be used for identification, overview, supplying instructions, positipn, size, representation, and media. As there are so many uses for symbols, every situation and every context requires the consistent use and explanation of the symbols used. The variety of symbols sed in schematic pictures makes it hard for users to understand the communication. ELLEMTEL, a Swedish research and development company, has created a set of defined symbols to be used as image elements. This allows a standard set of symbols to be used ;n various schematic diagrams which makes it an easier and cost e2fective method for readers to understand the message. (Contains 11 references.) (JLB)
