Approaches to human-computer interaction based on observation of a software developer

The human-computer interaction is important concern of working with computer system, especially in the growing trend of multi-display work environments. This paper introduces an approach of interaction with computer system based on observation of the software developer. This interaction has additional benefits in multi-display work environment. It connects multiple computer displays as one user interface, in which the developer can execute commands by his look. The main contribution of this paper is to show usefulness of dynamic reactions in multi-display work environment, for example with activation of the program window on the watched monitor.
