In face-to-face settings such as meeting rooms or classrooms, it is possible to have multiple dialogical spaces within one place. This provides an opportunity to easily access others' opinions and ideas through dialogues with nearby individuals, contributing to increased creativity and understanding in group discussions for problem-solving within t...

Studies on reinforcement learning have developed the representation of curiosity, which is a type of intrinsic motivation that leads to high performance in a certain type of tasks. However, these studies have not thoroughly examined the internal cognitive mechanisms leading to this performance. In contrast to this previous framework, we propose a m...

We respond to unpleasant sounds in our daily lives by blocking out sound environments that we find unpleasant. This may be because of our helplessness in interfering with these sounds. However, blocking limits the range of sound selection. To reduce discomfort from unpleasant sound, rather than blocking the sound environment, this study aimed to ma...

For generative AIs to be trustworthy, establishing transparent common grounding with humans is essential. As a preparation toward human-model common grounding, this study examines the process of model-model common grounding. In this context, common ground is defined as a cognitive framework shared among agents in communication, enabling the connect...

Voice communication is the most familiar interaction mode for people in face-to-face scenarios. People can participate in multiple dialogues by controlling their gaze, body orientation, and physical distance from the speaker. Participation in multiple dialogues results in sharing of opinions and information transfer among groups and can be useful f...

In care facilities, demonstrative words such as “this” and “that” are frequently used to quickly share information and work instructions between staff members in the same space. According to the related research, Chinese and Vietnamese demonstrative words are not synonymous with Japanese ones, suggesting that there are differences in the spatial do...

コグニティブインタラクションは，従来の認知科学や情報科学だけではなしえていない，「状況に応じて，人と自然に，かつ持続的にインタラクションが可能な人工物を設計するための基礎理論」です．本書は，その入門書です．AIやロボットが人の社会生活にとけこむためには，人と協調行動をとれなければいけません．それには，コミュニケーション，つまり，意思疎通の能力が欠かせません．しかし，言語によるコミュニケーションよりも，非言語情報によるインタラクションのほうが重要になることがよくあります．相手が人であれ，動物であれ，AIやロボットなどの人工物であれ，人は相手の意図や欲求などの心的状況を読み取り，それに適応した行動をとるという，コグニティブ（認知的）インタラクションを繰り返すことで，円滑に対話を行っていると考えら...

At the beginning of verbal interaction, a dialogue’s premise must be shared by demonstrating a talking behavior to another and then talking easily to him/her. In particular, when talking to an unspecified person in a public scene, the other person’s internal state must be estimated concerning the dialogue and an action chosen based on that other pe...

To date, many studies concerned with intrinsic motivation in humans and artificial agents based on a reinforcement learning framework have been conducted. However, these studies have rarely explained the correspondence between intrinsic motivation and other essential cognitive functions. This study aims to build a method to express curiosity in new...

We propose an agent model that determines its behavior from an internal state and a spatial relationship with a target to generate approaching and avoiding behaviors in encounter scenes. This model is based on the relationship with an opponent rather than with a scenario. The agent moves to increase the utility value obtained from the preferences f...

In this study, we analyzed the human’s moving trajectories in the encounter scene based on a proposed model. The model of agent possesses preferences for a relationship with a target. The model associates the intensity of aggressive and passive involvements based on the relative distance and the relative angle of the partner. In the scenario of the...

In the field of Human-Agent Interaction (HAI), continuation of interaction is one of the main areas of research. If the behavior of the agent is too predictable, humans stop interacting with it when they get bored. In this study, we aim to build agents that people want to keep interacting with, by employing the Adaptive Control of Thought-Rational...

To construct a general theory in human-agent interaction (HAI), it is essential to discuss how to generalize from models within the research area. In this study, we propose a formulation of HAI for the establishment of axiom systems. The environment for agents, behavior as a time change in the environment, and the internal state as an evaluation of...

Currently, it is difficult for humans and AI agents to cooperate because the agent has incomplete intention understanding. In this paper, we propose the design of cooperative interaction between humans and AI creatures. As an experiment, two creatures learned to lift a heavy box in a virtual environment simultaneously. As a result, one of the creat...

This study aims to clarify a person’s impressions during the course of a conversation. In conversations between a person and a chatbot, we evaluated the impressions formed on reading text created by a human and text created by a chatbot. In terms of question/answer relevance, it was found that chatbot-created answers could not relate to or meet the...

To design agent behavior in the initial phase of communication, we propose an agent model that possesses preferences for a relationship with a target. As an internal state, this model considers two relationship preferences with a target: control and acceptance. The agent's spatial behavior, which is represented by a change in its position, is deter...

Previous researches suggest that STEAM education contains both STEM-based and art-based ones. The purpose of this paper is to describe a design of collaborative creative activity in music and an evaluation method as a means of considering art-based STEAM education which improves students’ self-esteem. We designed a three-hours musical workshop for...

Communication, which begins by a consignor who verifies the signal of the communication needs and a receiver who recognizes it, is one element in the construction of relationships with others. Expression through language is effective for beginning to communicate with others. However, such expressions might produce social risk, because language expr...

This paper gives a detailed explanation of the proposal to build a mobile application for the purpose of communicating with other users of the mobile app who are in the vicinity of the communication initiator. This app enables the user to send text messages which may contain location-specific information.

It is difficult to communicate with an unknown robot because we don't know whether it can form a relationship with us or how it will behave without a context or premise for the interaction. We hypothesize that developing a relationship with an unknown robot first requires a notification phase with a robot that has the ability of coordinating behavi...

Humans can communicate because they adapt and adjust their behavior to each other. We hypothesize that developing a relationship with others requires coordinating the desire to communicate and that this coordination is related to agency identification. To model this initial phase of communication, we created an experimental environment to observe t...

We assume that subconscious interaction is carried out to make possible the forming of a communication relationship with the object. To model this stage of interaction, two experiments were carried out. We created an experimental environment to observe the interaction between a human and a robot whose behavior was actually mapped by another human....

People experience feelings of indebtedness when receiving help from an agent. This feeling of indebtedness has a potentially negative impact on the human attitude. However, few experimental analyses this evaluating effect of the help an agent are available. The aim of this study is to design an agent that can assist people without making them feel...

Humans can interact with strangers because they can communicate with each other. On the other hand, developing a relationship with an unknown artifact is difficult. In order to address this problem, existing studies have explored various approaches to the artifact's behavioral design. However, little research has been done on interaction where ther...

In this study, we suggest a method to coordinate turn-taking and talking in multi-party conversations by the gaze of a robot that participates on the side. Also, we use the experimental paradigm named 'Cooperative Turn-taking Game in Non-verbal Situation', which is a simplified multi-party conversation environment. We investigated whether designing...

To examine the identification of "social actors," we created an experimental environment to observe how people interpret the behavior of others. Our experimental environment, which physically provided interaction between a human and a computer, was a media system that connected two sides of the experimental environment to a computer network. In our...

Agency identification has been one of fundamental issue of Human-Agent Interaction studies. We carried out two experiments to examine what sort of behavior does make human identify the agency. And In order to examine agency identification, there was equipped an experimental environment for observing how people interpret other's behavior. The experi...

This paper shows a prototype system that provides a natural multi-party conversation environment among participants in different places. Eye gaze is an important feature for maintaining smooth multi-party conversations because it indicates whom the speech is addressing or nominates the next speaker. Nevertheless, most popular video conversation sys...

This paper investigates that human tend to percept of humanness and individuality to what features of human motion. We analyze from experiments based on test subjects how recognize of individuality by comparing a developed own self motion with other motion made by motion capture using Kinect sensor. The results showed except for the subjects could...

In face-to-face communication, we can confidently communicate through our bodies. Recently, agents have widely surfaced as existences that interact with humans, and several studies have investigated the formation of social relations with such agents. This study focuses on the possibility that the impression of embodied agents and the way of interpr...

In face-to-face communication, we can confidently communicate through our bodies. Recently, agents have widely surfaced as existences that interact with humans, and several studies have investigated the formation of social relations with such agents. This research focuses on ‘sharing an environment’ when humans communicate with humans, and we adapt...

Our study aims to determine how an agent should be designed to perform cooperative work smoothly. From previous experiments, it has been suggested that a human does not acknowledge an agent as a real participant. We considered how we could confirm the above possibility with a cognitive experiment. We designed an experiment with a game format to det...

An experiment was conducted in which participants remotely operated a goalkeeper robot to defend its goal from the kicker robot. Participants were assigned to two types of experimental conditions. Participants assigned to the first condition watched video...

Embodied interaction does not necessarily require direct face-to-face situation, but it can be organized by sharing the third party indirectly common to the participants. In this paper, an experiment is conducted to examine how two persons orally coordinate their intention and action in order to achieve a given experimental task. As a result, it is...

This paper investigates how people attribute the individuality of autonomy on a remote manipulated robot. In order to explore this issue, an experiment was conducted that the participants remotely manipulated the "keeper robot" by wireless controller to defend and keep its goal from the "kicker robot". The participants were assigned two types of ex...

In this paper, we focus on co-embodied interaction between two persons who occupy a differentiated situation in the same environment. An experiment is conducted to examine how two persons orally coordinate their intention and action in order to achieve a given experimental task. As a result, it is suggested that the co-embodied interaction efficien...

In the case of real world HAI, human physically situates his/her ownbody to interact with agent. Therefore it is naturally considered thatagent shares its circumstances with the human when the HAI wasperformed in real world. On the other hand, there is no HAI studyexploring human awareness of sharable circumstances when the agent iscomposed virtual...

In mother‐infant interactions, the mother talks in a special voice that is characterized by elevated fundamental frequency (pitch) and exaggerated intonation contours, and the infant turns a face toward the voice and smiles naturally. This case suggests that humans react automatically to the special prosody without understanding of the lexical mean...

This study aims to establish an accessible interaction model that resembles barrier-free human communication, which is examined through the eye movement. It utilizes human communication as a social function in human-agent interaction. This has two advantages: (1) decreasing user's cognitive load to communicate with other people, (2) avoiding specia...

An embodied interactive agent has a virtual body that is generally drawn by CG animation. We intuitively assume that the agent's body primarily expresses non-verbal messages, or symbolizes its social characteristics through its appearance. However, we have not objectively elucidated the expressive competence of an agent's body beyond the conclusion...

Our research focuses on the nature of voice interaction and activation of psychological tendencies in humans by the power of prosody sounds. This study examines whether people's impressions and behaviours are affected by variations in the speed of hummed sounds. The sounds consist of just prosodic components similar to continuous humming on the ope...

Our research goal is to investigate interpersonal relations involving empathy in human–computer interaction. We focus on mimicry behavior and its ability to elicit intentional stance of a partner in interaction. In this study, we conducted a psychological experiment to examine how prosodic mimicry by computers affects people. An interactive system...

Social persuasion abounds in human-human interactions. Attitudes and behaviors of people are invariably influenced by the attitudes and behaviors of other people as well as our social roles/relationships toward them. In the pedagogic scene, the relationship between teacher and learner produces one of the most typical interactions, in which the teac...

We discuss, in this paper, the design of a life-like agent interface that considers the social aspects in human -agent interaction. The underlying hypothesis of the design is that human social behaviors toward life-like agents are on a par with those toward humans. Humans tend to sympathize with and follow other humans based on their affiliation ne...

This study focuses on the design of a life-like agent interface that considers the social aspects in human-agent interaction. We have designed and incorporated life-like guide agents into an exhibition guide system on the hypothesis that a user of the system establishes a social relationship with a life-like interface agent similar to a relationshi...

In this paper, we describe results from an experiment on interaction with artificial creatures that mimic the human voice echoicly using inarticulate sounds. We consider that humans are apt to find a partner’s intention or emotion towards themselves, when the partner mimics their utterances echoicly at the prosodic level. As a result, we regard tha...

This paper describes an interactive system called “Talking Eye”, which casually chats with humans via speech voice, and reports the results of a psychological experiment to evaluate social behaviors on interaction with the Talking Eye system.We have been investigating the mechanism of chatting in order to create local interaction between humans and...

Introduction It has become a commonplace idea that anthropomorphic and believable agents must have personalities. In order to attempt to create personality for agents virtually, a number of technologies in artificial intelligence, pattern recognition, and multi-modal interfaces have been devoted to creating a sentience of human-like qualities in co...

The study reported in this paper explores the validity of the hypothesis that Human-Computer interaction displays the same dynamics as HumanHuman interaction. The study also addresses the issue of universality and cultural dependency of social responses in Human-Computer interactions. A series of psychological experiments are conducted both with Am...

. Human-Computer interaction may be correlated with social interaction and cultural norms. We examined how Japanese and American people respond to a computer as a social entity and how cultural differences between Japanese and American behavioral norms in reciprocal social interaction play a role in this response. Reciprocity is the most powerful a...

In order for a computer agent to be accepted and function properly within a community of people, an appropriate social interaction scheme has to be established. We conducted an experiment to investigate the effect of sharing opinions with interface agents on subsequent human behaviors. In the first stage of the experiment, either a positive sharing...

People tend to favor the opinions of those who previously made the same decisions as theirs. We conducted an experiment to investigate the effect of sharing opinions with interface agents on subsequent human behaviors. Three agents with distinctive appearances were used in the experiment. In the first stage, several questions are posed to a subject...
