By the application of electronics and computer operated machines nearly arbitrary design of controlling and operating the technical equipment seems possible. So more and more the question arises: what is operable by the human operator and what leads probably to a disaster due to much stress. By applying systems ergonomic rules, this can be avoided to a far extent. In order to consider these rules already in a early state of development it seems useful to incorporate such rules in digital human models. By this procedure cognitive human models will be created. The combination of such models with anthropometric digital human models will lead to the possibility to carry out virtual experiments under the condition of CAD-design. So in future more ergonomic knowledge will be considered by this new technique.

In order to clarify concrete difficulties in Web use, the behavior of younger and elderly users was observed with eye tracking during a timetable search task using electronic timetable systems on the Web. The result shows on the one hand common difficulties

This development is leading from an earlier “corrective ergonomics” to a new “prospective ergonomics”. There is an incredible improvement in the depth and also in the width of the abilities of the human models. And it can be expected that this development will continue for some time.

This entails the interaction of users with concepts and relations embodied in ontologies in a dialogue process that can be interpreted as a query or used as a sign to suggest other paths that could lead to casual encounters. In this paper, we describe a number of ontology-enabled search tactics that ...
