An end user visualization environment aims to empower end users to create graphical representations of phenomena within a scientific domain of interest. Research into end user visualization environments has traditionally focused on developing the human-computer interaction necessary to enable the quick and easy construction of domain-specific visualizations. That traditional focus has left open...

We investigated the early socio-communicative development of individuals with fragile X syndrome (FXS) by undertaking a retrospective analysis of family videos. Videos were analyzed to identify existing communicative forms and functions. Analyses were undertaken on seven children who were later diagnosed with FXS. The children were filmed when they were 9-12 months old and before being diagnose...

The aim of the present study was to investigate the effects of communicative intention on action. In Experiment 1 participants were requested to reach towards an object, grasp it, and either simply lift it (individual condition) or lift it with the intent to communicate a meaning to a partner (communicative condition). Movement kinematics were recorded using a three-dimensional motion analysis ...

The capabilities for agents in a team to anticipate information needs of teammates and proactively offer relevant information are highly desirable. However, such behaviors have not been fully prescribed by existing agent theories. We attempt to establish a theory about proactive information exchanges based on the SharedPlan framework and Cohen and Levesque’s formalization of communicative actio...

adopting a humanistic, communicative-based approach to semiotics, this paper aims at investigating the status of linguistic signs and their interaction with other communicative signs. the status of linguistic sign is first studied in semiotic theories spanning ancient, middle ages and modern era. based on the commonalities envisaged in four contemporary semiotic theories done in the spirit of t...

In this work we present a typology of eye closing behaviours based on a semantic taxonomy of communicative signals. The types of eye closing we investigate are blinks, eye-closures and winks performed during political debates. While other studies in the literature attempt to classify blinks and eye-closures according to their duration or (in)completeness of the closure, our study aims to distin...

We outline some components of a mentalist theory of human communicative competence. Communication in our species is an intentional and overt type of social interaction, based on each agent's capability of entertaining shared mental states and of acting so as to make certain mental states shared with the other. Communicative meaning is a matter of ascription: it is not an intrinsic property of a...

Information graphics, such as bar charts and line graphs, generally have a communicative message that they are intended to convey when they appear in popular media. The communicative signals present or absent in the graphic help convey these underlying intended messages. We have designed a Bayesian system that automatically extracts communicative signals from a grouped bar chart information gra...
