“…Despite thus providing an elementary and pivotal formalism for the nature of affordances, we however argue that this relation does not capture the various aspects of affordances in full detail as discussed next. Recent research (Ellis & Tucker, 2000;Wells, 2002;Cisek, 2007;Borghi & Riggio, 2015) has shown that affordances-outside of their fundamentality and independence-are, further to that, of a hierarchical, competitive and dynamic nature. This requires an extension of the relational scheme as introduced by Chemero (2003).…”

“…From a behavioral point of view, these interrelations and dependencies between affordances play a crucial role for action selection and behavior sculpting that goes beyond the present moment and allows planning into the future by chaining different affordances together. This ultimately results from the coordination of perception and the possibilities for action that a situation affords at a given time and place (Wells, 2002). For capturing this idea of a hierarchy among affordances coupled with the paradigm of behavior affording behavior (Gibson, 1977) in a relational manner, we introduce the relation Affords-Φ(Affords-φ 1 , Affords-φ 2 , .…”

Computational models of affordance in robotics: a taxonomy and systematic classification

J. J. Gibson's concept of affordance, one of the central pillars of ecological psychology, is a truly remarkable idea that provides a concise theory of animal perception predicated on environmental interaction. It is thus not surprising that this idea has also found its way into robotics research as one of the underlying theories for action perception. The success of the theory in this regard has meant that existing research is both abundant and diffuse by virtue of the pursuit of multiple different paths and techniques with the common goal of enabling robots to learn, perceive and act upon affordances. Up until now there has existed no systematic investigation of existing work in this field. Motivated by this circumstance, in this article we begin by defining a taxonomy for computational models of affordances rooted in a comprehensive analysis of the most prominent theoretical ideas of import in the field. Subsequently, after performing a systematic literature review, we provide a classification of existing research within our proposed taxonomy. Finally, by both quantitatively and qualitatively assessing the data resulting from the classification process, we highlight gaps in the research terrain and outline open questions for the investigation of affordances in robotics that we believe will help inform future work, prioritize research goals, and potentially advance the field towards greater robot autonomy.Prepared using sagej.cls [Version: 2015/06/09 v1.01]

“…It is important to understand that affordances are not merely properties of the environment: they exist only as a complementary relationship between an agent and its environment (Wells, 2002). Bucher and Helmond (2018) describe how the concept of affordances has been examined from different perspectives, such as high-level and low-level affordances (boyd, 2011), imagined affordances (Nagy & Neff, 2015), and vernacular affordances (Mcveigh-Schultz & Baym, 2015).…”

Framing online collective behavior within theoretical frameworks developed to describe offline phenomena is common in social media studies. This can limit the scope of analysis because the interplay between user capabilities, intentions, and platform architecture makes online exchanges different from offline interaction. We introduce a novel conception of online publicness, momentary connectedness, which is a structure of polymorphic computer-mediated sociality that includes transactive as well as non-transactive phenomenological online activity. We suggest that Twitter issue-response hashtags can be seen as affordances for momentary connectedness where Tweets that display broad and vague audience dimensions, as well as clusters with different interactional orientations, co-exist within the same topical network. We illustrate this polymorphism of momentary connectedness with a case study of an issue-response network.

“…Different researchers and scientists have defined affordance in their own terms and understanding as follows: Affordance is "Perception of the environment leads to a course of action" [3]; Affordance can be defined as "the actionable relation between the environment and an actor" (a person or animal or an object/artifact) [4]; "Affordances are properties of the environment taken relative to an observer." [5].…”

Abstract. Traditionally, design phase of construction projects is often performed with incomplete and inaccurate user preferences. This is due to inefficiencies in the methodologies used for capturing the user requirements that can subsequently lead to inconsistencies and result in non-optimised end-result. Iterations and subsequent reworks due to such design inefficiencies is one of the major reasons for unsuccessful project delivery as they impact project performance measures such as time and cost among others. The existing design theories and practice are primarily based on functional requirements. Function-based design deals with design of artifact alone, which may yield favourable or unfavourable consequences with the design artifact. However, incorporating other interactions such as interactions between user & designer is necessary for optimised end-result. Hence, the objective of this research work is to devise a systematic design methodology considering all the three interactions among users, designers and artefacts for improved design efficiency. In this study, it has been attempted to apply the theory of affordances in a case project that involves the design of an offshore facility. A step-by-step methodology for developing Affordance Structure Matrix (ASM), which integrates House of Quality (HOQ) and Design Structure Matrix (DSM), is proposed that can effectively capture the user requirements. HOQ is a popular quality management tool for capturing client requirements and DSM is a matrixbased tool that can capture the interdependency among the design entities. The proposed methodology utilises the strengths of both the tools, as DSM compliments HOQ in the process. In this methodology, different affordances such as AUA (Artifact-User-Affordance), AAA (Artifact-ArtifactAffordance) and DDA (Designer-Designer-Affordance) are captured systematically. Affordance is considered to be user-driven in this context that is in contrast to prevailing design methodologies. The initial feedback from industry on the proposed ASM-based design methodology is encouraging.
