Semiotic Dynamics for Embodied Agents

Automated Gesturing for Embodied Agents

Strategies for fast convergence in semiotic dynamics

Semiotic dynamics is a novel field that studies how semiotic conventions spread and stabilize in a population of agents. This is a central issue both for theoretical and technological reasons since large system made up of communicating agents, like web communities or artificial embodied agents teams, are getting widespread. In this paper we discuss a recently introduced simple multi-agent model...

Contextually Embodied Agents

In this chapter we present our work on the elaboration of a contextually embodied agent. We define such an agent as an agent capable of planning what to communicate as well as deciding with which verbal and nonverbal signals to output considering contextual information. We first present our 3D facial model that follows MPEG-4 standard. Then we present our taxonomy of communicative facial expres...

Net-mobile embodied agents

The Talking Heads experiment currently being conducted at Sony CSL Paris implements a network of mobile cognitive agents. Each node of the network consists of a workstation with two digital cameras through which the agents can perceive the world. When installed on a node, agents construct classifications of what they ’see’ through the cameras and interact with each other to develop a simple lan...

Collective Learning and Semiotic Dynamics

Abstract. We report on a case study in the emergence of a lexicon in a group of autonomous distributed agents situated and grounded in an open environment. Because the agents are autonomous, grounded, and situated, the possible words and possible meanings are not fixed but continuously change as the agents autonomously evolve their communication system and adapt it to novel situations. The case...
