We revisit the notion of object affordances, an idea that speaks to an object’s functional properties more than its class label. We study the problem of spatially localizing affordances in the form of 2D segmentation masks annotated with discrete affordance labels. For example, we use affordance masks to denote on what surfaces a person sits, grabs, and looks at when interacting with a variety ...

Current approaches to visual object class detection mainly focus on the recognition of basic level categories, such as cars, motorbikes, mugs and bottles. Although these approaches have demonstrated impressive performance in terms of recognition, their restriction to these categories seems inadequate in the context of embodied, cognitive agents. Here, distinguishing objects according to functio...

Road networks, roads, and junctions are examples of natural language terms whose semantics can be described by affordances of their physical referents. In order to define affordances in such a way that they can be used for classifying and describing instances in a geographic database, one has to deal with the problems of informational incompleteness and limited definability. In this paper, we p...

Reasoning about objects and their affordances is a fundamental problem for visual intelligence. Most of the previous work casts this problem as a classification task where separate classifiers are trained to label objects, recognize attributes, or assign affordances. In this work, we consider the problem of object affordance reasoning using a knowledge base representation. Diverse information o...

The evolution of social media has introduced novel possibilities for work and interaction in organizations. The wiki technology is one important kind of social media technologies that is often used to facilitate the creation and sharing of organizational knowledge within communities. Using an affordance lens, we seek to understand the relationship between social media and organizations through ...

According to several authors in psychology and neurosciences, our ability to perceive affordances is subtended by motor simulation mechanisms. Such mechanisms provide dynamic representations of feasible actions, thus enabling to scale the surrounding structures on the behavioural repertoire and capacities supported by our body. This attractive hypothesis has been taken up in robotics, to build ...

The notion of affordance remains elusive, notwithstanding its importance for the representation agency, cognition, and behaviors. This paper lays down a foundation an ontology affordances by elaborating idea “core affordance” which would serve as common ground explaining existing diverse conceptions their interrelationships. For this purpose, it analyzes M. T. Turvey’s dispositional theory in l...

Recalibration of affordance perception allows observers to adapt to changes in the body's size or abilities that alter possibilities for action. Of key interest is understanding how exploratory behaviors lead to successful recalibration. The present study was designed to test a novel hypothesis-that the same processes of exploration and recalibration should generalize between affordances that s...
