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...

Planning precise manipulation in robotics to perform grasp and release-related operations, while interacting with humans is a challenging problem. Reinforcement learning (RL) has the potential make robots attain this capability. In paper, we propose an affordance-based human-robot interaction (HRI) framework, aiming reduce action space size that would considerably impede exploration efficiency ...

Gibson’s notion of affordance seems to attract roboticists’ attention. On a phenomenological level, it allows functions, which have “somehow” been implemented, to be described using a new terminology. However, that does not mean that the affordance notion is of help for building robots and their controllers. This paper explores viewing an affordance as an abstraction from a robot-environment re...

Gibson developed the affordance concept to complement his theory of direct perception that stands in sharp contrast with the prevalent inferential theories of perception. A comparison of the two approaches shows that the distinction between them also has an ontological aspect. We trace the history and newer formalizations of the notion of affordance and discuss some competing opinions on its sc...

Recent years, Gibson's affordance concept has drawn many attentions in the field of human-computer interface and product design. However, the development of affordance concept in design practice is by far not yet matured, and the differentiation between affordance and symbolic meaning of designed artifacts is not clear. As a result, that wrongly exercising the techniques of “Product Semantics” ...

Autonomous agents must often detect affordances: the set of behaviors enabled by a situation. Affordance detection is particularly helpful in domains with large action spaces, allowing the agent to prune its search space by avoiding futile behaviors. This paper presents a method for affordance extraction via word embeddings trained on a tagged Wikipedia corpus. The resulting word vectors are tr...

A contemporary view of motor development considers environmental influences as critical factors in optimal growth and behavior, with the home being the primary agent. The intent of this communication is to introduce the Affordances in the Home Environment for Motor Development Self-Report (AHEMD-SR) to early childhood practitioners. The AHEMD-SR is a reliable and valid parental self-report asse...

This study investigates the impact of hyperlink affordance, psychological reactance, perceived loss of freedom, perceived business tie between sites, and trust in source site, on trust in target site. Hyperlink affordance represents the extent that the Web encourages users’ behavior. Perceived loss of freedom is based on psychological reactance, which refers to the extent that users react to hy...

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...
