Representational affordances in design, with examples from analogy making and optimization
Affordances in design can be understood as the action possibilities of a user interacting with a designed object. In this paper, we develop the notion of representational affordances to denote affordances provided by design representations to the designer as the user of these representations. A major characteristic of representational affordances is that they do not have to rely on existing representations but can drive the construction of new representations that may then afford different design actions. We describe representational affordances ontologically, proposing three affordance types: reflexive, reactive and reflective. We illustrate them with examples of analogy making and optimization.
