The simple perception of an object can potentiate an associated action. This affordance effect depends heavily on the action context in which the object is presented. In recent years, psychologists, psychiatrists, and phenomenologists have agreed that subjects with schizophrenia may not perceive the affordances of people or objects that could lead to a loss of ease in their actions. We examined...

PERCEPTION AND ACTION ARE TIGHTLY LINKED objects may be perceived not only in terms of visual features, but also in terms of possibilities for action. Previous studies showed that when a centrally located object has a salient graspable feature (e.g., a handle), it facilitates motor responses corresponding with the feature's position. However, such so-called affordance effects have been criticiz...

Bingham, Schmidt, and Rosenblum (Bingham, G. P., Schmidt, R. C., & Rosenblum, L. D. (1989). Hefting for a maximum distance throw: A smart perceptual mechanism. Journal of Experimental Psychology: Human Perception and Performance, 15, 507-528) found that skilled throwers could heft objects and select the weight in each size that they could throw to a maximum distance. Bingham et al. hypothesized...

A detection scheme is presented for maneuvering affordance in noisy imagery. By introducing a mental maneuvering process within an intentional coordinate system, image features are assumed to be represented in terms of directional Fourier images. The detectability of affordance patterns has been verified through experimental studies.

Intuitive interactions are supported by users’ implicit and explicit learning experiences. But, determining user knowledge can be difficult. With many options available for eliciting that knowledge, we tested the effectiveness of two methods – performance and reflection. Users were presented with simple interactions that had varying levels of intuitiveness (affordance, convention, bias). They w...

This paper explores three potential affordances (social, technical and pedagogical) of wikis in the context of designing 32 teachers’ learning of classroom management cases. Two learning environments were designed and two groups of the teacher-participants posted their own written and audio cases, identified problems, discussed and proposed solutions with the input of their peers, in the respec...

If autonomous agents like humans and robots act in physical space, several types of conflicts can occur that result from the fact that actions occupy space. To avoid such conflicts, social robots must have the capacity to consider the actions taken by other robots and by humans. This thesis proposes a conceptual framework which can be used to specify knowledge about spatial needs of activities ...

In this study, we propose a research model to assess the effect of a mobile health (mHealth) app on exercise motivation and physical activity of individuals based on the design and self-determination theory. The research model is formulated from the perspective of motivation affordance and gamification. We will discuss how the use of specific gamified features of the mHealth app can trigger/aff...

The theory of affordances, a conceptual pillar of the ecological approach to perception and action, has the potential to become a guiding principle for research on perception and action in sport. Affordances are opportunities for action. They describe the environment in terms of behaviors that are possible at a given moment under a given set of conditions. Affordances capture the tight coupling...

This paper argues that concepts derived from affordance theories are highly useful in understanding the role of online technologies in learning. However, it is suggested that the value of this approach is maximised when the focus is moved away from the inherent properties of the technologies to the opportunities for learning provided by the total context in which the technologies are embedded. ...
