Experimental evaluation of a tide prediction display based on the ecological interface design framework

This study evaluates whether the approach of ecological interface design (EID) can be applied to natural systems. Whereas the EID has proved its worth in a number of studies done at interfaces for complex artificial systems, its application to natural systems is just emerging. A display was designed for tide predictions. This new tidal display, referred to as the ecological document (ED), was evaluated against a classical table format and a commercially available graphical display, to assess the cognitive contribution of the ED to user performance for maritime novices and experts. The results are that the ED leads to less misreading, shorter response times, and a subjective preference among novices and experts. In particular, response times to questions concerning abstract functions of the domain decrease with the use of the ED. Thus, a document reflecting the domain can significantly improve information retrieval, and in particular cognitive processing on abstract functions.
