Gibson used "affordance" to describe how animals perceive and interact with their environment. Since the term was coined, many studies, both theoretical as well as empirical, have been done. We conducted a review of the 56 most cited works on physical affordances to answer: (1) What methods have been used to study affordances, and how have they changed with time? (2) How has the definition of affordances evolved over time? We went through papers decade-wise and compare their key contributions. Finally, we discuss how the definition and research on affordances has evolved in the last 40 years.

During the third millennium BC, new types of anthropogenic landscape emerged across northern Europe: heathlands and pasture. These open landscapes afforded mobile pastoralism and the arena for a new funerary practice: barrow building. Here, the authors define this entanglement of people, animals and landscapes as a literal and figurative ‘ancestral commons’. Focusing on western Jutland, they combine palaeoecological and archaeological evidence to characterise the form and temporal depth of the co-emergent links between pastoralism, barrows and mobility. Conceptualising the ancestral commons as a deep-time entanglement, characterised by rhythms of physical and metaphorical movement, reveals a landscape that afforded shared understanding of the ancestral past and a foundation for the subsequent Nordic Bronze Age.

This work investigates how the concept of affordance should be revised following the digital evolution. Starting from a review of the literature about affordance, the most acknowledged constructs are compared with the variegated definitions of digital artefacts. The paper proposes a definition of digital affordance, overcoming the inconsistencies identified in the literature. The study is enriched by a series of interviews to investigate the final users' perception of affordance. Finally, the paper shows the application of the proposed model with a case study related to food delivery services.

This study advances an original theoretical framework to understand the deployment of Information and Communication Technologies (ICTs) in political contention. It argues that we should not look only at the use of ICTs in contention, as technologies are not “born” to be used in and for political activism. Rather, people appropriate and manoeuvre technologies—some but not others—for such purposes, in specific contexts. This study proposes a relational understanding of ICT uses in contention, taking into account their technicalities and their sociality, as well as the transformation and actualisation that occurs between them. It suggests that an investigation necessitates the perception of communication technologies as a repertoire of contention on the basis of affordances that structure the possibilities of the use of technology. The study further presents an application of the framework in cases of protests in mainland China. Through fieldwork and in-depth interviews, this study indicates that the choice of (certain functions of) mobile phones as protest repertoire derives from a confluence of (a) a given social group’s habitus of media use that manifests particular affordances, and (b) the learned experience of the contested means of the past in official mass communication. It concludes that what people do and do not do with ICTs in political contention is significantly shaped by affordances and habitus, thereby revealing the dynamics behind repertoire selection and constraint.

The importance of affordance in Engineering design is well established. Artifacts that are able to activate spontaneous and immediate users’ reactions are considered the outcome of good design practice.

A huge effort has been made by researchers for understanding affordances: yet these efforts have been somewhat elusive. In particular, they have been limited to case studies and experimental studies, usually involving a small subset of affordances. No systematic effort has been carried out to list all known affordance effects. This paper offers preliminary steps for such an ambitious effort.

We propose a set of three different approaches of Natural Language Processing techniques to be used to extract meaningful affordance information from the full text of patents: 1) a simple word search, 2) a lexicon of affordances and 3) a rule-based system.

The results give in-depth measures of how rare affordances in patents are, and a fine grain analysis of the linguistical construction of affordances. Finally, we show an interesting output of our method, that has detected affordances for disabled people, showing the ability of our system to automatically collect design-relevant knowledge.

The action property of an object appears to function as an intrinsic part of its mental representation. This phenomenon has been demonstrated in cases where although the grasp response evoked by a visual object is irrelevant to a participant’s task it still appears to be encoded. This is an affordance effect. Recent findings have shown that dangerous objects can modulate the motor system by evoking aversive affordances. However, the way the time course of response activation generated by the dangerous object develops remains unclear. To investigate this process, we used a priming paradigm that varied the stimulus-onset asynchrony (SOA) between a prime and a target. Participants were asked to judge a symbol after presentation of a dangerous object. Results showed a significant congruency effect between the affordance of the ignored object and the requisite response when the SOA was 800 and 1,200 ms, (t(29) = 4.13, p < .001; t(29) = 2.56, p < .05, respectively). However, with briefer SOAs (0 and 400 ms), this congruency effect was not observed (ps > .10). Results indicate the time course of response activation with a dangerous object are relatively long-lasting.

As a result of the exclusive use of extremely small megaliths (miniliths), the prehistoric stone settings of Exmoor, south-west England, challenge current approaches to the interpretation of monumental stone architecture during the later Neolithic and Early Bronze Age. Whilst the broader context of the practice of erecting tiny upright stones (a seemingly diverse and widespread phenomenon) and the reasons why this diminutive architecture has tended to escape sustained critical comment have been explored (smaller stone elements being relegated to a generalised background or subsidiary role such as ‘packing’), attempts to explain the settings have been remarkably few. Drawing upon the results of ten years of piecemeal fieldwork on the moor the present paper seeks to rectify this, arguing that far from being generalised ritual structures or metaphorical expressions of hunting groups, the tiny stones were, instead, an integral part of a dynamic human–animal landscape of movement and pause.

The objective of this research is to develop a computational representation of knowledge associated with affordance-based design (ABD). The ABD ontology formalizes the entities, properties, and relationships within the domains of ABD. The ontology enables designers to describe the affordances of existing products and specify the intended affordances of future products in line with ABD. The ontology consists of 14 concepts and 5 relationships. The ontology is developed using Protégé 4.3 and DL-query to query and reason with the ontology. The ontology is demonstrated using a consumer vacuum cleaner. The formal ontology serves as the basis for developing computer support for ABD applications. When implemented, these design tools will help designers manage the affordances of artifacts being designed, specifying the interacting entities of every affordance when a three-dimensional model of the artifact is available. Further, these software tools could be used to support ABD methods.

We describe three approaches to identify novel product affordances: affordance of absence; insights from lead users, specifically do-it-yourselfers (DIYers); and natural-language searches. While these approaches were separately pursued, we show their connection to each other in this paper. We begin by describing the affordance of absence, inspired by insights on affordances arising from a lack of resources. For example, in the absence of specialized tools, more general tools are used to accomplish similar tasks. Such absence clarifies how other tools could be modified to add relevant features and identifies critical features of the absent tool. In addition, the temporary removal of physical features and objects enables user interaction in ways that may not emerge in their presence. Affordance of absence has the potential to more fully specify affordances for a given object and to help overcome functional fixedness. For the second approach, we describe insights from DIYers obtained from the “IKEA hackers” online community. We consider DIYers lead users for seeking out and exploiting product affordances, often transforming product functions dramatically. We also discuss their projects through the lens of affordance of absence. For the third approach, we outline our natural-language approach to affordance extraction, beginning with consumer product reviews provided for Canadian Tire, a major Canadian retailer. We describe efforts toward automatically identifying less common affordances, and the use of cue phrases to highlight insightful DIY transformations from the IKEA hackers community. Finally, we comment on the potential value of this work for product design in general.
