Design for user experience: An affective-cognitive modeling perspective

This research proposes a new formalism to embody the human-product interactions in the product ecosystem context for enhancing user experience. A comprehensive formulation of the product ecosystem is presented with emphasis on the event-driven user experience. Next, a colored dynamic fuzzy Petri net (CDFPN) model is proposed to capture the causal relations embedded in users´ affective and cognitive processes. In a case example of designing a subway station ecosystem, it is demonstrated that the concept of ecosystem is an innovative step toward affective-cognitive engineering and the CDFPN approach is appropriate to include the user experience in system development toward high added-value.
