The concept of affordance has been brought to HCI by Don Norman, who has recently protested against its misuse by designers. They say they will put affordances in the interface, or afford this or that to the users, but Norman points out that affordances only exist inasmuch as they are perceived by users. Therefore, it doesn’t make sense to use the term as designers do. This paper takes the desi...

It has been conceived that children learn new objects through their affordances, that is, the actions that can be taken on them. We suggest that web pages also have affordances defined in terms of the users’ information need they meet. An assumption of the proposed approach is that different parts of a text may not be equally important / relevant to a given query. Judgment on the relevance of a...

In this study we untangle the sociomaterial interactions between developers, users, and artifacts by analyzing what types of affordances occur in the interactions between actors and artifacts in the context of group generativity. Hereto, we conducted an indepth ethnographic and interaction analysis of video data of the interactions of groups of people with each other and with a set of self-deve...

10 Abstract Performing any behavior requires perceiving 11 affordances—whether and how that behavior can be per12 formed. Perception of affordances exhibits action scaling— 13 choices about when to transition between two different modes 14 of behavior reflect the fit between action capabilities and en15 vironmental properties. The boundary between distances that 16 are perceived to be reachable...

The experience of virtual environments is often based on contradictions: the user should perceive the environment and objects as real, and yet the behavior of the environment is typically unreal; the user should accept the world as a temporary reality, yet at the same time interact with it magically. At the core of these differences is affordances and the question: Are virtual affordances the s...
