In reaction to Norman’s (1999) essay on misuse of the term affordance in human-computer interaction literature, this article is a concept paper affirming the importance of this powerful concept, reinforcing Norman’s distinctions of terminology, and expanding on the usefulness of the concepts in terms of their application to interaction design and evaluation. We define and use four complementary...

Limb apraxia, a disorder of higher order motor control, has long been a challenge for clinical assessment and understanding (Leiguarda and Marsden, 2000). The deficits originally described in limb apraxia (Liepmann, 1920) have been classified by the nature of the errors made by the patients leading to, namely, ideational and ideomotor apraxia. The dual stream hypothesis (Goodale and Milner, 199...

This paper is a comparative study of gestural interaction with musical sound, designed to gain insight into the notion of musical affordance on interactive music systems. We conducted an interview base user study trialing three accelerometer based devices, an iPhone, a Wii-mote, and an Axivity Wax prototype, with four kinds of musical sound, including percussion, stringed instruments, and voice...

High affordance stimuli are associated with an enhancement in the activation of the corresponding motor programs. Such over-activation of motor programs may imply a decrease in performances based on inhibitory control. However, recent data suggest that high affordance stimuli are associated with a widespread privileged neural activation that goes beyond motor representations. In this case, we c...

Affordances, as for example grasping possibilities, are known to play a role in the guidance of human attention but have not been considered in artificial attention systems so far. Extending our earlier work, we investigate the combination of affordance estimation and visual saliency in an artificial visual attention model. Different models based on saliency, affordance estimation, or their com...

This work creates a model of the value different external viewpoints robot performing tasks. The current state practice is to use teleoperated assistant provide view task being performed by primary robot; however, choice ad hoc and does not always lead improved performance. research applies psychomotor approach develop relative quality using Gibsonian affordances. In this approach, for affordan...

Affordances (unit utility, functional and topological relationships) and semantic scene understanding are key to building a generic, scalable and cognitive architecture for visual perception. ‘Affordance based object recognition’ or recognition based on affordance features is an important step in this regard. In this paper, we extend the scope of affordance features to define ‘Conceptual Equiva...

The growing interest of IS researchers in using the theory of Affordances for studying the uses and consequences of the IT artefact calls for an integrative view on the subject. The originating literature is dispersed and the definition of the concept of affordance varies in these studies. With this paper we offer a framework for organizing the existing interdisciplinary literature modeling aff...
