What is affordance theory and how can it be used in communication research?

Affordance theory proposes that the use of an object is intrinsically determined by its physical shape. However, when translated to digital objects, affordance theory loses explanatory power, as the same physical affordances, for example, screens, can have many socially constructed meanings and can be used in many ways. Furthermore, the affordance theory core idea that physical affordances have intrinsic, pre-cognitive meaning cannot be sustained for the highly symbolic nature of digital affordances, which gain meaning through social learning and use. A possible way to solve this issue is to think about on-screen affordances as symbols and affordance research as a semiotic and linguistic enterprise

Affordance Theory for Improving the Rapid Generation, Composability, and Reusability of Synthetic Agents and Objects

This paper describes an effort to revise the PMFserv agent architecture in order to implement J.J. Gibson\u27s Affordance Theory. The theoretical justification for this revision is outlined along with the engineering constraints that inspired it. We describe the resulting architectural changes and the impact of those changes on the flexibility, ease of rapid scenario creation, and ability to reuse previous investments in knowledge engineering offered by our architecture. The level of effort required to build a new scenario within PMFserv both with and without the revisions suggested by Affordance Theory is compared. We conclude that Affordance Theory is an elegant solution to the problem of providing both rapid scenario development and the simulation of individual differences in perception, culture, and emotionality within the same agent architecture

Reconciling Function- and Affordance-Based Design

Traditional engineering design methods are based on Simon\u27s (1969) use of the concept function, and as such collectively suffer from both theoretical and practical shortcomings. Researchers in the field of affordance-based design have borrowed from ecological psychology in an attempt to address the blind spots of function-based design, developing alternative ontologies and design processes. This dissertation presents function and affordance theory as both compatible and complimentary. We first present a hybrid approach to design for technology change, followed by a reconciliation and integration of function and affordance ontologies for use in design. We explore the integration of a standard function-based design method with an affordance-based design method, and demonstrate how affordance theory can guide the early application of function-based design. Finally, we discuss the practical and philosophical ramifications of embracing affordance theory\u27s roots in ecology and ecological psychology, and explore the insights and opportunities made possible by an ecological approach to engineering design. The primary contribution of this research is the development of an integrated ontology for describing and designing technological systems using both function- and affordance-based methods

Making sense of visual management through affordance theory

Visual management is much used within operations management practice, particularly in association with process improvement initiatives in diverse areas such as production and healthcare. The practitioner literature abounds with suggested best practice. However, there is little attempt to theorise about why the design and use of ‘visual’ devices for such process improvement works in practice. Within this paper we describe a novel theory of operation which highlights the role that material and visual artefacts proposed by visual management practitioners play within particular ways of organising work. We develop an innovative way of employing the theory of affordances to explain how first and second order affordances, situated around the visual devices at the heart of visual management, connect three domains of action, which we refer to as articulation, communication and coordination. Our analysis of three cases from healthcare, clothing manufacturing and software production help ground the theorisation discussed

IT-Enabled Capabilities for Sustainable Supply Chain Management: An Affordance Theory Perspective

There is an increasing consumer pressure to improve the environmental and social impacts of supply chain activities, forcing organisations to adopt sustainable supply chain practices. However, the management of sustainable supply chain is complex because it is inter-organisational in nature involving different and sometimes conflicting objectives and priorities among various stakeholders. Successful implementation of sustainable supply chain practices requires a set of specific organisational capabilities. Currently, very little is known about what capabilities are required and how information technology (IT) can enable those capabilities. This paper aims to address this knowledge gap by identifying a set of possible IT-enabled capabilities based on Affordance Theory. We put forward a novel approach that demonstrates how Affordance Theory could be applied to discover the roles of IT in capability development to support the successful implementation of sustainable supply chain management (SSCM)

An athletic approach to studying perception-action integration: Does sport-specific training, and the impact of injury, influence how individuals visually guide navigation?

The objective of this thesis was to investigate perception-action integration capabilities of individuals during a choice navigation task. This task assessed navigation strategies in open space while individuals avoided colliding with two vertical obstacles that created a body-scaled, horizontal gap, at three varying obstacle distances from the starting location (3m, 5m, 7m). The two studies completed in this thesis employed the same paradigm to assess the hypothesized group differences. Gaze behaviours and kinematics of navigation strategies were compared between: 1) athletes specifically trained in navigating in open space versus non-athletes; and 2) athletes with post-concussion syndrome (PCS) versus non-concussed, specifically trained athletes. Specifically trained athletes have been identified as demonstrating more successful perception-action integration in discrete motor tasks related to their sport (Mann et al., 2007; Vickers, 2007). However, whether these abilities translate to the continuous motor task of obstacle avoidance in open space was unknown. The purpose of Study 1 was to identify the influence of sport-specific training on navigating in open space (i.e. navigational strategies of large field sport athletes) compared to age-matched, non-athletes. It was hypothesized that specifically-trained athletes would demonstrate fewer, longer fixations, suggesting a more successful perception-action integration strategy (as defined by Mann et al., 2007), and would employ more sport-specific navigation strategies than non-athletes by maintaining their straight trajectory toward the goal (Fajen & Warren, 2003). Athletes were found to make fewer, longer fixations than non-athletes. However, no differences were observed between navigation strategies of the two groups, nor were any kinematic measures found to differ between groups. It can be concluded that athletes and non-athletes differentially obtain visual information to perform the same actions, suggesting that athletes and non-athletes differentially perform perception-action integration when navigating in open space. Future studies are required to identify sport-specific nuances of navigation (moving obstacles, running) to better identify athletic-related navigation strategies. Although athletic training can enhance perception-action integration strategies, sport-related injuries can hinder this process. Following a concussion, individuals experience deficits of perception-action integration that persist well beyond 30 days of recovery, post-concussion (Baker and Cinelli, 2014; Slobounov et al., 2006). These perception-action integration deficits may also exist in individual with postconcussion syndrome (PCS). The purpose of the Study 2 was to identify whether perception-action integration deficits persist with the persistent physical symptoms of concussion characteristic of PCS. The current study revealed that athletes with PCS did not differ from non-concussed athletes on any measure of visual fixation strategy, nor were they found to differ on any kinematic measure assessed. These findings suggest that in the context of the current paradigm, athletes with PCS have no perception-action integration deficit. In that, athletes with PCS may have adapted perception-action integration strategies to navigate with equal efficiency as a specifically-trained group of athletes or that the paradigm was not sensitive enough to identify these differences. Such findings suggest that more research is required to assess what, if any, perception-action integration deficits persist with persisting physical symptoms of PCS to better benefit rehabilitative procedures and outcomes for these individuals. Together, these studies add to what was previously known about perception-action integration, as it relates to navigation. Both studies assessed perception-action integration in unique populations that add to understanding of behavioural dynamics in the sport setting. Study 1 builds on a line of research assessing affordance theory and behavioural dynamics in sport (Fajen, Riley, & Turvey, 2008). The findings of this study suggest that although navigation strategies did not differ between specifically trained athletes and non-athletes, visual search strategies employed in task did. Such findings add to the understanding that sport-specific training influences perception-action integration, through our understanding of how athletes obtain visual information to perform actions. This thesis did not identify perception-action integration deficits in athletes with PCS. These findings suggest that the individuals in the present study likely adapted to their injury as they demonstrated equal ability in gaze and navigation strategies to specifically-trained athletes. As such, further research is required to assess the cognitive, motor, and sensory-motor deficits that may persist with the persisting physical symptoms of PCS. As individuals with PCS do not demonstrate similar visuomotor integration deficits as individuals with acute concussions (Baker & Cinelli, 2014), such individuals must be assessed and researched as a separate population

Do E-books Enhance the Reading Experience: An Affordance Theory Perspective

The digitisation of publishing has redefined the publishing industry and the reading experience for consumers. E-readers and smart devices are now part of the value proposition of e-books offering affordances ranging from overcoming the physical limitations of print books to providing the functionality of information systems to the reading experience. A gap exists in understanding the preferences of readers for print books and e-books. Through an affordance theory lens this paper aims to go some way to fill the gap in understand the perception of reading e-books on smart devices as well as advancing the use of affordance theory in information systems research by demonstrating the use of a proposed theoretical model. Using netnography an appropriate sample is identified and thematic analysis is used to identify affordances, positive and negative. The theoretical model is illustrated in the context of e-books and e-readers

Clarifying the Relationship Between Fitness Apps’ Affordances and Features

Affordance theory posits that users\u27 engagement with technology can form affordances that facilitate goal-oriented actions. Studies investigating affordances of fitness apps employed diverse definitions of affordances. Relying on the affordance theory, we developed principles to help identify fitness apps\u27 affordances: (1) affordances require users\u27 perception of their usefulness, (2) app features exist regardless of users\u27 perception, and (3) a single affordance can be enabled by multiple features. Using these principles, we examined fitness apps\u27 affordances reported in the literature. Our results show that 12 affordances out of the 17 followed the principles, and the remainder are features of the apps. We then mapped the 12 affordances against Fitbit app\u27s features. Our mapping identified several instances where multiple features can enable a single affordance and a single Fitbit feature could enable multiple affordances. Our findings enhance research studying the roles the features and affordances play in users’ engagement with fitness apps

Designing products with a focus on self-explanatory assembly, a case study

Designing products with a focus on self-explanatory assembly can reduce the use of procedural instructions and the associated problems. This paper describes how different groups of students, in two different design-engineering courses designed or redesigned products in an attempt to make the assembly of the product self-explanatory. The design outcomes are discussed in relation to the design context and linked to existing theory on design for meaning
