INTEGRATING THEORY DEVELOPMENT WITH DESIGN EVALUATION

In this paper, we recruit the construct of psychological design rationale as a framework for integrating theory development with design evaluation in HCI. We propose that, in some cases, part of an artefact's psychological design rationale can be regarded as inherited from second-order artefacts (prescriptive design models, architectures and genres, tools and environments, interface styles). We show how evaluation data pertaining to an artefact can be used to test and develop the second-order artefact from which it inherits.
