the interaction between users and products, is one of the key factors in design process and assessment of products too. because design for user’s perception, is a specific and technical issue. designers refer to psychology and psychological theories to understand how on the one hand, form and other physical characteristics, and on the other hand, user intentions and values, affect the interacti...

The paper examines the notion that Information and Communication Technologies (ICT) have affordances that epitomize the features of our late modern age (Giddens, 1991) and explores whether these affordances (Salomon, 1993, p. 51) can be used to facilitate particular approaches to educational practice. It argues that a clear articulation of these affordances would enable us to understand how the...

Given that a user interface interacts with users, a critical factor to be considered in improving the usability of an e-learning user interface is user-friendliness. Affordances enable users to more easily approach and engage in learning tasks because they strengthen positive, activating emotions. However, most studies on affordances limit themselves to an examination of the affordance attribut...

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 preferenc...

In this paper we propose an approach to distinguish affordances on a fine-grained scale. We define an anthropomorphic agent model and parameterized affordance models. The agent model is transformed according to affordance parameters to detect affordances in the input data. We present first results on distinguishing two closely related affordances derived from sitting. The promising results supp...

Mobile devices offer technology affordances that were not previously available. With the rapid acceptance of these technologies it is imperative to understand and investigate both their positive and negative effects on individuals. In this ongoing research we have conceptualized an affordance of mobile devices in order to examine these positive and negative effects. Quality of Access Continuity...

In this article, I argue that affordances are properties of the animal–environment system, that is, that they are emergent properties that do not inhere in either the environment or the animal. I critique and review the formal definition of affordance offered by Turvey (1992). Turvey defined affordances as properties of the environment; I discuss some consequences of this and argue that Turvey’...
