This thesis investigates the ergonomic design of sources of information generated by search engines. Based on experiments by means of gaze tracking, an empirical model regarding the user’s behavior when selecting appropriate source of information is defined. According to this general user model, cognitive resources are being allocated in an instrumental-rational way depending on subjective cost-benefit considerations. The model is specified by a subjective hypothesis on the presumption regarding the applicability of the information. From a practical point of view, ergonomic recommendations for designing sources of information are derived. In addition, a process of self-organization is proposed as a result of the sources of information’s utilization. The findings indicate a multiplier effect, encouraging the user’s motivation to apply a knowledge management system.
