Coding of visual information is an important step in designing man-machine dialogues. After an analysis of the coding and decoding procedures the human properties in information transmission tasks are described by applying the Shannon-Wiener measure of information. The strongly limited human capacity for absolute judgements in information transmission tasks leads to the recommendation of a rather small number of coding steps when using single stimulus dimensions. In a comparison different codes like analogue, digital, alphanumerical, chromatic, pictorial and blinking signals are discussed in order to give application-oriented design rules.
