Scene Understanding is among the grand challenges of computer vision. We consider indoor scenes in 3D space and motivate an affordance based approach to autonomously discover common objects. Relationship between visual entities and their supported affordances is modelled as a clustering problem in a feature space reflecting human embodiment. In the current scope of work we only consider geometr...

This article investigates users’ perceptions of videoconferencing (VC) as a mode of communication in business meetings. The study demonstrates that affordance theory is a fruitful theoretical perspective for understanding what shapes users’ perceptions of how well VC works as a communication technology in business meetings. The article is based on observation and qualitative interviews with VC ...

Cañal-Bruland and van der Kamp present an argument about the incommensurate relationship between affordance perception and spatial perception in a criticism of Proffitt and Linkenauger's phenotypic approach to perception. Many of their criticisms are based on a difference in the interpretation of the core ideas underlying the phenotypic approach. The most important of these differences in inter...

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...

In this paper we use the concept of ‘social translucence’ to understand users’ initial reaction to, and use of, the voice communication channel provided by Xbox Live. We found that although users expected voice to be an advance over text-based communication, in practice they found voice difficult to use. In particular, users experienced difficulties controlling the voice channel and these diffi...

We address the problem of bootstrapping language acquisition for an artificial system similarly to what is observed in experiments with human infants. Our method works by associating meanings to words in manipulation tasks, as a robot interacts with objects and listens to verbal descriptions of the interactions. The model is based on an affordance network, i.e., a mapping between robot actions,...

Given a single RGB image our goal is to label every pixel with an affordance type. By affordance, we mean an object’s capability to readily support a certain human action, without requiring precursor actions. We focus on segmenting the following five affordance types in indoor scenes: ‘walkable’, ‘sittable’, ‘lyable’, ‘reachable’, and ‘movable’. Our approach uses a deep architecture, consisting...

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...
