The Third European Workshop on Ecological Psychology: The Keynote Lectures

Intentional dynamics is a modeling framework that provides methods and measures with which to evaluate and predict goal-directed behavior. The authors introduce the framework by showing how it can be used to solve two general problems in the design of human–machine interaction as they are encountered by designers of driving assistance systems. The first problem the authors treat is that of path planning on tasks in which multiple goals have to be satisfied, necessitating the evaluation of performance relative to conflicting criteria. The second problem is that of design selection in which designers need to assess the effectiveness of competing designs in improving performance relative to such criteria. The authors close with a small empirical study testing the predictive validity of the approach.
