The idea that to perceive an object is to perceive its affordances—that is, the interactions of the perceiver with the world that the object supports or affords—is attractive from the point of view of theories in cognitive science that emphasize the fundamental role of actions in representing an agent’s knowledge about the world. However, in this general form, the notion has so far lacked a for...

Perceived affordance is utilized as a theoretical lens to explore factors influencing consumers’ positive or negative perceptions of Web advertisements, which is one type of information artifacts. Content and form are two main attributes shared by information artifacts. Based on the literature review and content analysis, a conceptual framework is proposed to shed light on perceived affordance ...

Physical interfaces have been proposed as a way to realize natural interactions with ubiquitous computing environments. The successful design of such interfaces requires design approaches that integrate aspects of our world which are usually treated separately in traditional system development approaches. This paper describes a design approach based on Gibson concept of affordance. We demonstra...

This paper develops and evaluates a new tensor field representation to express the geometric affordance of one object over another. We expand the well known bisector surface representation to one that is weight-driven and that retains the provenance of surface points with directional vectors. We also incorporate the notion of affordance keypoints which allow for faster decisions at a point of q...

The bidirectional control procedure was used to determine whether pigeons (Columba livia) would imitate a demonstrator that pushed a sliding screen for food. One group of observers saw a trained demonstrator push a sliding screen door with its beak (imitation group), whereas 2 other groups watched the screen move independently (possibly learning how the environment works) with a conspecific eit...

In this paper, we consider the influence of Gibson's affordance theory on the design of robotic agents. Affordance theory (and the ecological approach to agent design in general) has in many cases contributed to the development of successful robotic systems; we provide a brief survey of AI research in this area. However, there remain significant issues that complicate discussions on this topic,...

In an ERP study we investigate the time course of the interaction between the lexically specified telic role of a noun and the contextually provided ad-hoc affordance induced by a linguistic discourse. If preceded by a neutral discourse context, a verb inconsistent with the telic role in a sentence elicits an enhanced N400 compared to a congruent verb. However, if the preceding discourse contex...

The purpose of this study was to explore how users perceive the affordances of an object from specific operation tasks. These affordances can be specified in terms of perceptual information. To this end, the eye-tracking technique was employed to capture what product parts uses’ fixation focused on when using a product for specific operational tasks. The results show that, for physical-behavior...

The development of computer technology has created artifacts that have more complex and intelligent functions. Such artifacts need more sophisticated interfaces than primitive artifacts. In this paper, we discuss which characteristics are appropriate for interfaces with artifacts and propose a concept of active affordance. We describe an autonomous mobile chair that we built as a test bed for a...

We present a study that explores the affordance evoked by sound and sound-gesture mappings. In order to do this, we make use of a sensor system with minimal form factor in a user study that minimizes cultural association. The present study focuses on understanding how participants describe sounds and gestures produced while playing designed sonic interaction mappings. This approach seeks to mov...
