Affordances of a product are messages which could be perceived by a human user so that the product function can work by a user's activities naturally induced with the help of such messages. Affordance features are structural elements providing affordances. That is, affordance features and their relations as well as human users are critical constituents for affordance. In this research, we introduce three types of affordance features as Functional Affordance Feature (FAF) related to the physical properties for behaviors of an object by physical laws, Ergonomics Affordance Feature (EAF) related to convenience for user activities and Informative Affordance Feature (IAF) related to the properties that can help human understand the functionalities and so guide him/her to proper operations. Above all, identification of affordances and affordance feature reasoning of a typical household product is conducted through function and user task analysis reflecting user aspects and product function aspects. Some critical affordances and affordance features are identified through geometric and function reasoning.
