Mobile Robot’s Vertical Oscillation and Body Posture Enhancing Human Perception of the Robot’s Locomotion Speed
Mobile robots have seamlessly integrated into our daily lives, providing various services to humans. The key to successful interaction between humans and these robots lies in human acceptance. To enhance this acceptance, humans must intuitively and easily grasp the intentions behind the locomotion of mobile robots. Just as humans communicate changes in their walking or running speed through vertical oscillation and body leaning, this study delves…
Case report
Although companion robots have demonstrated psychological benefits for older adults, most studies have focused on short-term use or institutional settings. This case series with integrated qualitative analysis describes five cases involving the long-term use of a conversational companion robot (RoBoHoN, Sharp) among community-dwelling women aged 85 to 90 with mild cognitive impairment or late-onset psychosis. After an initial exploratory phase (2…
Cross-cultural moral judgments and emotions in preschoolers
The study aims to investigate the effect of cultural background between Italy and Japan on 5-year-old children’s moral judgements and emotion attributions towards human and robot. The children watched videos drawn from classic ‘happy victimizer’ stories, in which the transgressors were either a child or a robot, violating rules against stealing or not sharing. We assessed the children’s attribution of emotions both to the transgressors and to the…
Affirmative Large Language Model-Based Dialogue Robots for Broadening or Deepening the Perspective of Children
This study aims to establish a method for designing dialogue robots that can broaden or deepen the perspectives of children. Previous research has suggested that artificial intelligence (AI) can broaden or deepen perspectives by facilitating critical dialogues. Critical thinking emphasizes not only counterarguments, but also appropriate evaluations and affirmations. However, the development and validation of AI and robots that consider this aspec…
Impact of Table-Top Robots on Questionnaire Response Rates at a Science Museum
To facilitate the integration of robot applications in real environments, evaluating whether or how much the presence of a robot entity influences human behavior is important. In addition, it is necessary to evaluate the influence of voice-only systems, which can be implemented more easily than robots. Therefore, in this study, we conducted two experiments to evaluate the visitor behavior at a science museum when requested to respond to a questio…
Extrovert or Introvert? GAN-Based Humanoid Upper-Body Gesture Generation for Different Impressions
Gestures, a form of body language, significantly influence how users perceive humanoid robots. Recent data-driven methods for co-speech gestures have successfully enhanced the naturalness of the generated gestures. Moreover, compared to rule-based systems, these methods are more generalizable for unseen speech input. However, many of these methods cannot directly influence people’s perceptions of robots. The primary challenge lies in the intricac…
Effectiveness of Conversational Robots Capable of Estimating and Modeling User Values
Personalizing a dialogue system according to the user has been recognized to have various positive effects. Despite the significance of user values, concepts guiding choices and evaluations being recognized in communication, they have not been considered in personalized dialogue systems. Therefore, this study constructs a dialogue system that understands user values through conversation. Furthermore, the impact of understanding values on the inte…
Shared Knowledge in Human-Robot Interaction (HRI)
According to the Theory of Natural Pedagogy, object-directed emotion may provide different information depending on the context: in a communicative context, the information conveys culturally shared knowledge regarding the emotional valence of an object and is generalizable to other individuals, whereas, in a non-communicative context, information is interpreted as a subjective disposition of the person expressing the emotion, i.e., personal pref…
Effects of Demonstrating Consensus Between Robots to Change User’s Opinion
In recent years, the research of humanoid robots that can change users’ opinions has been conducted extensively. In particular, two robots have been found to be able to improve their persuasiveness by cooperating with each other in a sophisticated manner. Previous studies have evaluated the changes in opinions when robots showed consensus building. However, users did not participate in the conversations, and the optimal strategy may change depend…
Robot-Mediated Intergenerational Childcare
Intergenerational interactions between children and older adults are gaining broader recognition because of their mutual benefits. However, such interactions face practical limitations owing to potential disease transmission and the poor health of older adults for face-to-face interactions. This study explores robot-mediated interactions as a potential solution to address these issues. In this study, older adults remotely controlled a social robo…

Comparison of Outcomes Between Robot-Assisted Language Learning System and Human Tutors
This study explores how much current mainstream Robot-Assisted Language Learning (RALL) systems produce outcomes compared to human tutors instructing a typical English conversation lesson. To this end, an experiment was conducted with 26 participants divided in RALL (14 participants) and human tutor (12 participants) groups. All participants took a pre-test on the first day, followed by 30 min of study per day for 7 days, and 3 post-tests on the …
Having Different Dialog Roles in Telecommunication by Using Two Teleoperated Robots Reduces an Operator’s Guilt
In recent years, applications of social robots as the operator’s avatar have been widely studied for remote conversation with rich nonverbal information. Having another side-participant robot beside the avatar robot of the operator was found to be effective for providing long-lasting backchannels to the interlocutor. The side-participant robot is also expected to play a role in assisting human participation in multiparty conversations. However, s…
Self-administered questionnaires enhance emotion estimation of individuals with autism spectrum disorders in a robotic interview setting
These findings support the hypothesis that assessing self-administered questionnaire data contributes to the development of an automated estimation of an individual's affective state and engagement. Given the efficacy of including self-administered questionnaire data, future studies should confirm the effectiveness of such long-term intervention with a robot to maintain participants' motivation based on the proposed method of emotion estimation
Therapeutic potential of robots for people who stutter
The communication robot and tandem utterance robot can sometimes be burdensome, although both robots were always easier to talk to for PWS in this preliminary study. The participants with positive speech-related attitudes were more inclined to decrease stuttering-related psychological symptoms when communicating with CommU than when communicating with humans. The participants whose speech-related attitudes were negative were more inclined to show…
Infants’ Prediction of Humanoid Robot’s Goal-Directed Action
Several studies have shown that infants anticipate human goal-directed actions, but not robot’s ones. However, the studies focusing on the robot goal-directed actions have mainly analyzed the effect of mechanical arms on infant’s attention. To date, the prediction of goal-directed actions in infants has not yet been studied when the agent is a humanoid robot. Given this lack of evidence in infancy research, the present study aims at analyzing inf…
Religion-Related Values Differently Influence Moral Attitude for Robots in the United States and Japan
Increasing evidence suggests that people show moral concern for robots among other nonhuman entities. Furthermore, people’s attitudes toward new automated technologies such as robots and artificial intelligence (AI) are influenced by their social backgrounds, including religion. Two specific religion-related values, that is, animism and anthropocentrism, have been recognized to influence preference for and familiarity with robots. However, how th…

Group-Based Online Job Interview Training Program Using Virtual Robot for Individuals With Autism Spectrum Disorders
The rapid expansion of online job interviews during the COVID-19 pandemic is expected to continue after the pandemic has subsided. These interviews are a significant barrier for individuals with autism spectrum disorders (ASD). There is little evidence-based training for online job interviews for individuals with ASD, and the development of new trainings is expected. In an effort to facilitate online job interview skill acquisition for individual…
Android Robot Promotes Disclosure of Negative Narratives by Individuals With Autism Spectrum Disorders
Many individuals with autism spectrum disorders (ASD) demonstrate some challenges with personal narrative writing. Sentence completion tests (SCT) is a class of semi-structured projective techniques and encourage respondents to disclose their private narratives. Even in SCT, only providing beginning of sentences is inadequate to compensate atypicalities in their creativity and imagination, and self-disclosure is difficult for many individuals wit…
Differences in the Optimal Motion of Android Robots for the Ease of Communications Among Individuals With Autism Spectrum Disorders
Android robots are employed in various fields. Many individuals with autism spectrum disorders (ASD) have the motivation and aptitude for using such robots. Interactions with these robots are structured to resemble social situations in which certain social behaviors can occur and to simulate daily life. Considering that individuals with ASD have strong likes and dislikes, ensuring not only the optimal appearance but also the optimal motion of rob…
Robotic question support system to reduce hesitation for face‐to‐face questions in lectures
Encouraging students to actively ask questions during lectures is a formidable challenge that can be addressed through innovative use of information technology. We developed a robotic system that allows students in a lecture to collaboratively decide questions to be asked by a humanoid robot. To verify whether the system reduces hesitation to ask questions during lectures, 62 university students were divided into two groups, and each attended two…

Interactive Robots as Social Partners and Peer Tutors for Children
Robots increasingly have the potential to interact with people in daily life. It is believed that, based on this ability, they will play an essential role in human society in the not-so-distant future. This article examined the proposition that robots could form relationships with children and that children might learn from robots as they learn from other children. In this article, this idea is studied in an 18-day field trial held at a Japanese …
Robovie, you'll have to go into the closet now
Children will increasingly come of age with personified robots and potentially form social and even moral relationships with them. What will such relationships look like? To address this question, 90 children (9-, 12-, and 15-year-olds) initially interacted with a humanoid robot, Robovie, in 15-min sessions. Each session ended when an experimenter interrupted Robovie's turn at a game and, against Robovie's stated objections, put Robovie into a cl…

Persistence of the uncanny valley
The uncanny valley theory proposed by Mori has been heavily investigated in the recent years by researchers from various fields. However, the videos and images used in these studies did not permit any human interaction with the uncanny objects. Therefore, in the field of human-robot interaction it is still unclear what, if any, impact an uncanny-looking robot will have in the context of an interaction. In this paper we describe an exploratory emp…

A Robot Is Not Worth Another
Recent technological developments in robotics has driven the design and production of different humanoid robots. Several studies have highlighted that the presence of human-like physical features could lead both adults and children to anthropomorphize the robots. In the present study we aimed to compare the attribution of mental states to two humanoid robots, NAO and Robovie, which differed in the degree of anthropomorphism. Children aged 5, 7, a…
Assessing Human Likeness by Eye Contact in an Android Testbed
The development of robots that closely resemble human beings enables us to investigate many phenomena related to human interactions that could not otherwise be investigated with mechanical-looking robots.This is because more humanlike devices are in a better position to elicit the kinds of responses people direct at each other.In particular, we cannot ignore the role of appearance in giving us a subjective impression of social presence or intelli…

Sharing Experiences to Help a Robot Present Its Mind and Sociability
Many social robots have emerged in public places to serve people. For these services, the robots are assumed to be able to present internal aspects (i.e., mind, sociability) to engage and interact with people over the long term. In this paper, we propose a novel dialogue structure called experience-based dialogue to help a robot present and maintain a good interaction over the long term. This dialogue structure contains a piece of knowledge and a…
Curiosity Did Not Kill the Robot
Learning from human interaction data is a promising approach for developing robot interaction logic, but behaviors learned only from offline data simply represent the most frequent interaction patterns in the training data, without any adaptation for individual differences. We developed a robot that incorporates both data-driven and interactive learning. Our robot first learns high-level dialog and spatial behavior patterns from offline examples …

The uncanny advantage of using androids in cognitive and social science research
The development of robots that closely resemble human beings can contribute to cognitive research. An android provides an experimental apparatus that has the potential to be controlled more precisely than any human actor. However, preliminary results indicate that only very humanlike devices can elicit the broad range of responses that people typically direct toward each other. Conversely, to build androids capable of emulating human behavior, it…

A Two-Month Field Trial in an Elementary School for Long-Term Human–Robot Interaction
Interactive robots participating in our daily lives should have the fundamental ability to socially communicate with humans. In this paper, we propose a mechanism for two social communication abilities: forming long-term relationships and estimating friendly relationships among people. The mechanism for long-term relationships is based on three principles of behavior design. The robot we developed, Robovie, is able to interact with children in th…
Geminoid
Why are people attracted to humanoid robots and androids? The answer is simple: because human beings are attuned to understand or interpret human expressions and behaviors, especially those that exist in their surroundings. As they grow, infants, who are supposedly born with the ability to discriminate various types of stimuli, gradually adapt and fine-tune their interpretations of detailed social clues from other voices, languages, facial expres…
How to Build an Intentional Android
This study examined whether young children are able to imitate a robot's goal‐directed actions. Children (24–35 months old) viewed videos showing a robot attempting to manipulate an object (e.g., putting beads inside a cup) but failing to achieve its goal (e.g., beads fell outside the cup). In 1 video, the robot made eye contact with a human before and after it failed the action. In another video, the robot did not make eye contact with the human…
