Nested affordance-based intuitive design tool: Affordance interaction matrix
Abstract
AbstractAffordances serve as design cues, facilitating users in effortlessly identifying the intended use of objects. However, due to the phenomenological nature of the affordance concept, its application and understanding in the human-computer interaction (HCI) domain remain uncertain, resulting in limited utilization in design practice. This study introduces the concept of nested affordances, linking affordances more closely and explicitly with perception. We reposition the affordance concept and transform it into a design tool—the Affordance Interaction Matrix (AIM). This matrix captures the nested relationships and perceptual conflicts between target affordances within a product, assisting designers in identifying and eliminating potential confusion for users when facing a design, providing implicit interaction cues. The AIM-based design method proposed in this research addresses the shortcomings in describing product affordance interactions, focusing on the natural guidance of specific behaviors. This approach enables designers to clarify intuitive interaction foundations and make swift, effective decisions. Finally, the paper demonstrates the application and advantages of AIM through a practical case study of accessible kitchen furniture.
