Zusammenfassung
To develop a product out of a set of given variables and operators, complex
information processing and the application of problem-solving strategies is
needed. Unfortunately, these complex requirements on human problem-solving
abilities are confronted with the designer’s cognitive and creative limitations resulting
from a restricted working-memory capacity. To overcome these limitations
and to foster a creative and innovative product development, suitable supporting
systems are needed. Their development should be based on a profound understanding
of the cognitive actions and perceptual processes that are involved in design
problem-solving. Thereby, a permanent exchange between internal thinking, reasoning
and decision making steps and external writing, sketching and verbalisation
steps takes place. The most challenging question in this context is how external
representations should be configured and how interaction with these representations
should be implemented to efficiently combine mental and motor actions. Another
interesting question is, whether virtual environments are helpful for design
problem-solving by providing information-rich, interactive visualisations in a 3D
manner. To answer these questions and to deduce cognitively based guidelines for
the development of design support systems, several experiments in virtual environments
are planned in a laboratory setting.
