The thesis at hand shall be a contribution to describe the Interaction between men and computer adequately and moreover to take into consideration empirical tests. In a first step, relevant theoretical linguistic approaches will be introduced. In this context, the class of speech-acts which are called 'computives' and have been developed by Schmitz, will decisively be enhanced by semiotical aspects. In a next step, the usefulness of empirical tests and the relevance of physiological data will be pointed out to reveal the stressors and to avoid them in future. Finally, possible research projects for the future according to the new theory of man-computer-interaction are described.
