To improve the validity of traffic simulations in urban and suburban areas, we propose to consider the driving context and the driver behavior in terms of space occupation. We endow agent driver with an ego-centered representation of the environment. This representation permits the agent to take a decision in terms of space occupation. Our agent driver model is based on the concept of affordanc...

Planning algorithms for non-deterministic domains are often intractable in large state spaces due to the well-known “curse of dimensionality.” Existing approaches to address this problem fail to prevent the planner from considering many actions which would be obviously irrelevant to a human solving the same problem. We formalize the notion of affordances [7] as knowledge added to an MDP that pr...

In this paper we describe a system for middle school students and teachers that combines the affordances of paper with the affordances of digital books. Our teacher composer tool focuses on providing teachers with tools to annotate books with reading comprehension hints for their students. The student annotation tool focuses on providing students with highlighters, stamps and sticky notes to ai...

Motor affordances are important for object knowledge. Semantic tasks on visual objects often show interactions with motor actions. Prior neuro-imaging studies suggested that motor affordances also play a role in visual working memory for objects. When participants remembered manipulable objects (e.g., hammer) greater premotor cortex activation was observed than when they remembered non-manipula...

Purpose – The purpose of this paper is to investigate the face-to-face citizen service encounter in public administrations’ front offices, and present a novel qualification approach to empower service personnel on-the-job, and thereby deepen the knowledge on the role of information and communication technology for advancing governmental reforms. Design/methodology/approach – The presented study...

Affordances (unit utility, functional and topological relationships) and semantic scene understanding are key to building a generic, scalable and cognitive architecture for visual perception. ‘Affordance based object recognition’ or recognition based on affordance features is an important step in this regard. In this paper, we extend the scope of affordance features to define ‘Conceptual Equiva...

the interaction between users and products, is one of the key factors in design process and assessment of products too. because design for user’s perception, is a specific and technical issue. designers refer to psychology and psychological theories to understand how on the one hand, form and other physical characteristics, and on the other hand, user intentions and values, affect the interacti...

This paper is a comparative study of gestural interaction with musical sound, designed to gain insight into the notion of musical affordance on interactive music systems. We conducted an interview base user study trialing three accelerometer based devices, an iPhone, a Wii-mote, and an Axivity Wax prototype, with four kinds of musical sound, including percussion, stringed instruments, and voice...

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...
