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...

A system is described which takes synergies extracted from human grasp experiments and maps these onto a robot vision and hand-arm platform to facilitate the transfer of skills [1]. This system forms part of a framework which is extended by adding a self organizing map based affordance learning system. This affordance system learns the correlations between perceived object features and relevant...

From the technical point of view, it is possible for a developer to embed and visualize as much information as possible in an open-ended virtual geographic environment, meanwhile, allow the user to interactively query and manipulate the information. However, the design and interpretation hitherto is a more or less blind experiment. In order to raise the awareness of this problem, the author rev...

This paper describes an effort to revise the PMFserv agent architecture in order to implement J.J. Gibson's Affordance Theory. The theoretical justification for this revision is outlined along with the engineering constraints that inspired it. We describe the resulting architectural changes and the impact of those changes on the flexibility, ease of rapid scenario creation, and ability to reuse...

We address the problem of affordance reasoning in diverse scenes that appear in the real world. Affordances relate the agent’s actions to their effects when taken on the surrounding objects. In our work, we take the egocentric view of the scene, and aim to reason about action-object affordances that respect both the physical world as well as the social norms imposed by the society. We also aim ...

We propose a theory of communicative interactions based on the idea that it is constitutive of interpersonal communication to create and manage a fragment of social reality. We define such a fragment in terms of joint commitments of the interactants, and analyze how these commitments are made in a conversation. We distinguish between three layers of joint commitments: those that regulate the em...

Judgments of affordances, the potential actions that an observer can carry out within an environment, require observers to relate information about their body to information in the environment. Although humans can accurately judge affordances for others, it is unknown whether other people's capability to act influences one's own affordance judgments. Based on theoretical accounts and recent emp...

The portability of a mobile device and the ubiquity of mobile Internet provide e-market users with more opportunities of access to e-commerce sites throughout a day. In this paper, we examine the access affordance of mobile technologies by analyzing the changes in purchase time dispersion of e-marketplace users after their adoption of mobile channel. By analyzing a large archival dataset includ...
