| Summary: | 博士 === 雲林科技大學 === 設計學研究所博士班 === 97 === Perception of affordances results from perceptual information. The existent-absent relationship between affordances and perceptual information can result in the affordance conditions, perceptible, hidden and false affordance. This study aims to explore affordance conditions of product parts and find out a way of how specific affordances could be presented. For the purpose, this study reviews the related literatures about affordances in design and affordance-information relationship. Furthermore, two applications of affordance concept in design and three categories of perceptual information about affordances are proposed and discussed in this study.
This study employs different case studies to explore and analyze affordance concept in design, perceptual information about affordances and affordance conditions of product parts. The results show that: 1) affordance for operability not only refers to the physical-corresponding relationship between user and object but also two certain parts; Affordance for functionality refers to a product’s intended function; 2) three categories of perceptual information about affordances, behavioural information, assemblage information and conventional information are proposed; 3) an affordance-information analysis scheme is proposed to serve to analyze the affordance conditions of product parts and present affordances of product parts for user-product interaction.
Finally, from usability test, this study outlines an extended affordance-information relationship in which another level of affordance condition, lucid affordance, is suggested to help more practically explain user-product interaction. Affordance for functionality should not only be perceptible, more importantly, but also lucid for users in user-product interaction. In addition, the conventional factors as strong cues can effectively guide users to perceive a product’s affordances in user-product interaction. The results would be contributive for designing and improving user-product interaction as design references.
