In order to support users to recover from erroneous changes or to explore previously executed modifications, collaborative editing systems offer the undo mechanism. Providing an undo feature in fully decentralised collaborative editors is challenging as users are allowed to revert any changes performed by any user. Operational transformation has been devised as a suitable mechanism for maintain...

To confirm the language independency of a communicative prosody generation from input word impression vector, we synthesized communicative Mandarin speech using prosodic characteristics of communicative Japanese speech. The fundamental frequency and duration characteristics of oneword “n” utterances of Japanese were copied to Mandarin through input word attributes. From the subjective impressio...

Communication is an essential skill for cooperative tasks, yet neuroevolved agents struggle to develop communicative behaviour. In fact, it has been shown that communicating agents are sometimes outperformed by noncommunicating ones on tasks that ostensibly require communication. In our paper, we explore mechanisms which could aid agents in developing communication through evolution. Specifical...

In this paper we describe Lokutor, a virtual human. Lokutor is a partially autonomous agent, living a 3D virtual environment. The agent can be controlled via natural language directives of the user (spoken or typed in) and by direct manipulation using a gra cal user interface. Its control system consists of a behavior-based reactive layer, a deliberative control layer and an motivational subsys...

A learning environment for the training of communicative competence has to consider the complexity of human experience, since it requires a number of cues that are managed hic et nunc in the flow of communicative exchange. Therefore, communicative competence has been traditionally considered as a typical face-to-face learning topic. So far, few opportunities exist to learn by experience in an e...

Communicative competence is one of the most highly sought after skills of prospective graduates among employers. In spite of its importance, the notion of communicative competence has been deemed fuzzy in Communication and Engineering studies. This fuzziness has undoubtedly led to tensions among stakeholders like educators and professional engineers across disciplinary tenures in interpreting t...

Communicative pointing is a human specific gesture which allows sharing information about a visual item with another person. It sets up a three-way relationship between a subject who points, an addressee and an object. Yet psychophysical and neuroimaging studies have focused on non-communicative pointing, which implies a two-way relationship between a subject and an object without the involveme...
