Abstract:
Visual representations can support communication in general and convey knowledge in an effective way. Moreover, in contrast to purely textually encoded information, visual notations can be processed in parallel by the human mind. However, a prerequisite is always a good visual notation. However, little attention is paid to the design and evaluation of visual notations in research. Mostly, more attention is paid to the semantics than to the syntax of visual notations. Therefore, a literature review is used to present the current state of research and to derive design and evaluation procedures for visual notations from the literature. Due to the highly individualized and varying evaluation procedures, especially in the field of empirical evaluation, an evaluation procedure is also developed that is largely software-supported and combines various aspects of the evaluation procedures in the literature. Thus, a high repeatability, a reduction of complexity for notation designers and test persons as well as a comparability of different evaluations can be achieved.
