Geoweb 2.0 for Participatory Urban Design: Affordances and Critical Success Factors

In this paper, we discuss the affordances of open-source Geoweb 2.0 platforms to support the participatory design of urban projects in real-world practices.We first introduce the two open-source platforms used in our study for testing purposes. Then, based on evidence from five different field studies we identify five affordances of these platforms: conversations on alternative urban projects, citizen consultation, design empowerment, design studio learning and design research. We elaborate on these in detail and identify a key set of success factors for the facilitation of better practices in the future

Dynamics of Affordances and Implications for Design

Affordance is an important concept in HCI. There are various interpretations of affordances but it has been difficult to use this concept for design purposes. Often the treatment of affordances in the current HCI literature has been as a one-to-one relationship between a user and an artefact. According to our views, affordance is a dynamic, always emerging relationship between a human and his environment. We believe that the social and cultural contexts within which an artefact is situated affect the way in which the artefact is used. Using a Structuration Theory approach, we argue that affordances need also be treated at a much broader level, encompassing social and cultural aspects. We suggest that affordances should be seen at three levels: single user, organizational (or work group) and societal. Focusing on the organizational level affordances, we provide details of several important factors that affect the emergence of affordances

Affordances in AI

Affordances in AI refer to a design methodology for creating artificial intelligence systems that are designed to perceive their environment in terms of its affordances (Sahin et al. 2007). Affordances in AI are adapted from affordances introduced in The Ecological Approach to Visual Perception by James J. Gibson (1979). Design methodologies in the applied sciences use affordances to represent potential actions that exist as a relationship between an agent and its environment. This approach to artificial intelligence is designed for autonomous agents, making it suitable for robotics and simulation

Using Debated Definitions of Affordances for A Qualitative Discussion of Campus Affordances

The goal of human factors is to examine and improve the relationship between individuals and their environment. This presentation will be a qualitative review and discussion of everyday environmental cues and affordances located around the University of Central Florida campus. The goal will be to discuss the relationship between the design of perceptual affordances and the user’s interpretation of the object\u27s intention. In general, affordances explain how perception guides an individual to respond to an object or situation. The theory of affordances is widely debated in the literature. As a result, two definitions of affordances will be compared and contrasted. The main arguments of interest are the classic approach to affordances (Gibson, 1977) and the modern approach (Stoffregen, 2003). Gibson coined the term “affordances” and argued that objects have action potential with an inherent meaning and that the environment offers something to the person. Stoffregen, on the other hand, has argued that there are emergent properties in the human-environment system that result in behavior and that objects have no inherent meaning. Examples of affordances will be explained, compared, and contrasted under both viewpoints. Additionally, several examples of campus affordances will be shown that demonstrate good and poor design. The design aspect of affordances will be examined with Norman’s (1988, 1999, 2002) approach. Norman referred to affordances as “perceived affordances” and argued that the designer of objects concerns himself and controls the perceived affordances of the system. Norman urged for the usability of objects, including objects that have never been seen before by the user. Suggestions for design improvement will be discussed. Overall, the environment may be designed in ways that afford certain actions, but it is up to the individual to perceive the environmental cue and the intended action. I will argue that the intended action should be evident to the individual and if what the user perceives and what the designer intended mismatch, this can result in poor design. In summation, this presentation will review the debates about defining an affordance, provide examples of affordances from the University of Central Florida campus and how these definitions would vary in describing objects, and make an argument about the design and usability of the objects

Designing constraints: composing and performing with digital musical systems

This paper investigates two central terms in Human Computer Interaction (HCI) – affordances and constraints – and studies their relevance to the design and understanding of digital musical systems. It argues that in the analysis of complex systems, such as new interfaces for musical expression (NIME), constraints are a more productive analytical tool than the common HCI usage of affordances. Constraints are seen as limitations enabling the musician to encapsulate a specific search space of both physical and compositional gestures, proscribing complexity in favor of a relatively simple set of rules that engender creativity. By exploring the design of three different digital musical systems, the paper defines constraints as a core attribute of mapping, whether in instruments or compositional systems. The paper describes the aspiration for designing constraints as twofold: to save time, as musical performance is typically a real-time process, and to minimize the performer’s cognitive load. Finally, it discusses skill and virtuosity in the realm of new musical interfaces for musical expression with regard to constraints

A design for affordances framework for product packaging: food packaging case study

Since affordances provided by packaging features play a major role in facilitating user packaging interaction, it is important to integrate the concept of affordances into the packaging design process and to understand the interrelationships between packaging features and affordances. A framework is proposed for linking user requirements to packaging design features utilizing the concept of affordances. The framework is accomplished in two main steps; first, determine the affordances required to facilitate performing packaging-related tasks, and second, link these affordances to packaging features. Previous packaging usability studies were reviewed to elicit requirements in terms of affordance properties such as intuitiveness, responsiveness, and clarity of information. The elicited properties represent the affordances of purchase-ability, store-ability, open-ability, reopen/reclose-ability, handle-ability, unpack-ability, and dispose-ability. An affordance structure matrix (ASM) was built to link user requirements, represented by affordance properties, to packaging features, and to appraise the links between them. To demonstrate its functionality, the framework was applied to assessment of a food packaging design. Further, a usability study conducted with 37 users agreed with the framework outcomes. The framework systematically incorporates user requirements for affordances into the design stage, thereby allowing modifications of packaging features to improve packaging designs based on affordance measures

Affording Affordances

A striking feature of the latest version of Dennett’s ‘big picture’ of the evolution of life and mind is frequent reference to ‘affordances’. An affordance is, roughly, a possibility for action for a creature in an environment. Given more than one possibility for action, a good question is: what will the creature actually do? I argue that affordances pose a problem of selection, and that a good general solution to this problem of mind-design is to implement a system of preferences

What do teachers attend to in curriculum materials?

In this paper, we describe an emerging methodology using eye tracking to explore teachers’ curricular attending as they interact with curriculum materials to design a lesson in order to learn what teachers pay attention to and how this attention shifts during planning. We propose affordances of this new method, remark on some of its limitations, and propose future directions

Affordances, constraints and information flows as ‘leverage points’ in design for sustainable behaviour

Copyright @ 2012 Social Science Electronic PublishingTwo of Donella Meadows' 'leverage points' for intervening in systems (1999) seem particularly pertinent to design for sustainable behaviour, in the sense that designers may have the scope to implement them in (re-)designing everyday products and services. The 'rules of the system' -- interpreted here to refer to affordances and constraints -- and the structure of information flows both offer a range of opportunities for design interventions to in fluence behaviour change, and in this paper, some of the implications and possibilities are discussed with reference to parallel concepts from within design, HCI and relevant areas of psychology

Learning with facilitation affordances: The case of citizens’ advice services

How can employees be qualified to provide sound customer advisory services? How can they be empowered to deliver the value of public sector modernization to customers? In this paper, we offer a novel approach to qualify service personnel on-the-job using “facilitation affordances”. In this approach, artifacts, providing appropriately designed facilitation affordances, are introduced into service personnel’s work practices. These facilitation artifacts invite them to start experiential learning, and, hence, to improve their advice giving behavior. To develop our approach, we followed a design research approach, here we developed a set of design requirements and, ultimately, five design principles for facilitation artifacts. We tested our approach in the context of citizens’ advice services in public administrations. We implemented a prototype facilitation artifact and conducted a user study with six real-world advisors and twelve clients. Our preliminary results show that the “learning with facilitation affordances”-approach promises to enhance the service personnel’s skills that matter in modern public administrations. Furthermore, with the proposed qualification approach and the design principles for facilitation artifacts, we seek to deepen the knowledge on the importance of affordances for learning and, concurrently, provide practitioners with useful guidelines to implement the “learning with facilitation affordances”-approach in their organizations
