Controlling the Gaze of Conversational Agents
نویسندگان
چکیده
We report on a pilot experiment that investigated the effects of different eye gaze behaviours of a cartoon-like talking face on the quality of human-agent dialogues. We compared a version of the talking face that roughly implements some patterns of human-like behaviour with two other versions. In one of the other versions the shifts in gaze were kept minimal and in the other version the shifts would occur randomly. The talking face has a number of restrictions. There is no speech recognition, so questions and replies have to be typed in by the users of the systems. Despite this restriction we found that participants that conversed with the agent that behaved according to the human-like patterns appreciated the agent better than participants that conversed with the other agents. Conversations with the optimal version also proceeded more efficiently. Participants needed less time to complete their task.

Conversational Gaze Aversion for Virtual Agents
In conversation, people avert their gaze from one another to achieve a number of conversational functions, including turn-taking, regulating intimacy, and indicating that cognitive effort is being put into planning an utterance. In this work, we enable virtual agents to effectively use gaze aversions to achieve these same functions in conversations with people. We extend existing social science...
متن کاملModelling Gaze Behaviour for Conversational Agents
In this paper we propose an eye gaze model for an embodied conversational agent that embeds information on communicative functions as well as on statistical information of gaze patterns. This latter information has been derived from the analytic studies of an annotated video-corpus of conversation dyads. We aim at generating different gaze behaviors to stimulate several personalized gaze habits...
متن کاملScrutinizing Natural Scenes: Controlling the Gaze of an Embodied Conversational Agent
We present here a system for controlling the eye gaze of a virtual embodied conversational agent able to perceive the physical environment in which it interacts. This system is inspired by known components of human visual attention system and reproduces its limitations in terms of visual acuity, sensitivity to movement, limitations of short-memory and object pursuit. The aim of this coupling be...
متن کاملAutomatic Generation of Gaze and Gestures for Dialogues between Embodied Conversational Agents: System Description and Study on Gaze Behavior
In this paper we introduce a system that automatically adds different types of non-verbal behavior to a given dialogue script between two virtual embodied agents. It allows us to transform a dialogue in text format into an agent behavior script enriched by eye gaze and conversational gesture behavior. The agents’ gaze behavior is informed by theories of human face-to-face gaze behavior. Gesture...

متن کاملAutomatic Generation of Conversational Behavior for Multiple Embodied Virtual Characters: The Rules and Models behind Our System
In this paper we presented the rules and algorithms we use to automatically generate non-verbal behavior like gestures and gaze for two embodied virtual agents. They allow us to transform a dialogue in text format into an agent behavior script enriched by eye gaze and conversational gesture behavior. The agents’ gaze behavior is informed by theories of human face-toface gaze behavior. Gestures ...
