    関西大学In this dissertation, we focus on physiological phenomena of robots as the expressive modality of their inner states and discuss the effectiveness of a robot expressing physiological phenomena, which are indispensable for living. We designed a body-emotion model showing the relationship between a) emotion as the inner state of the robot and b) physiological phenomena as physical changes, and we discuss the communication between humans and robots through involuntary physiological expression based on the model. In recent years, various robots for use in mental health care and communication support in medical/nursing care have been developed. The purpose of these systems is to enable communication between a robot and patients by an active approach of the robot through sound and body movement. In contrast to conventional approaches, our research is based on involuntary emotional expression through physiological phenomena of the robot. Physiological phenomena including breathing, heartbeat, and body temperature are essential functions for life activities, and these are closely related to the inner state of humans because physiological phenomena are caused by the emotional reaction of the limbic system transmitted via the autonomic nervous system. In human-robot communication through physical contact, we consider that physiological phenomena are one of the most important nonverbal modalities of the inner state as involuntary expressions. First, we focused on the robots\u27 expression of physiological phenomena, proposed the body-emotion model (BEM), which concerns the relationship between the inner state of robots and their involuntary physical reactions. We proposed a stuffed-toy robot system: BREAR―which has a mechanical structure to express the breathing, heartbeat, temperature and bodily movement. The result of experiment showed that a heartbeat, breathing and body temperature can express the robot\u27s living state and that the breathing speed is highly related to the robot\u27s emotion of arousal. We reviewed the experimental results and emotional generation mechanisms and discussed the design of the robot based on BEM. Based on our verification results, we determined that the design of the BEM-which involves the perception of the external situation, the matching with the memory, the change of the autonomic nervous parameter and the representation of the physiological phenomena - that is based on the relationship between the autonomic nervous system and emotional arousal is effective. Second, we discussed indirect communication between humans and robots through physiological phenomena - which consist of the breathing, heartbeats and body temperature - that express robots\u27 emotions. We set a situation with joint attention from the robot and user on emotional content and evaluated whether both the user\u27s emotional response to the content and the user\u27s impression of relationship between the user and the robot were changed by the physiological expressions of the robot. The results suggest that the physiological expression of the robot makes the user\u27s own emotions in the experience more excited or suppressed and that the robot\u27s expression increases impressions of closeness and sensitivity. Last, we discussed the future perspective of human-robot communication by physiological phenomena. Regarding the representation of the robots\u27 sense of life, it is thought that the user\u27s recognition that the robot is alive improves not only the moral effect on the understanding of the finiteness of life but also the attachment to the robot in long-term communication. Regarding the emotional expression mechanism based on life, it is expected that the robot can display a complicated internal state close to that of humans by combining intentionally expressed emotions and involuntary emotional expressions. If a robot can express a combination of realistic voluntary expressions, such as facial expressions and body movements, in combination with real involuntary expressions by using the real intentions and lying, it can be said that the robot has a more complicated internal state than that of a pet. By using a robot expressing a living state through physiological phenomena, it can be expected that the effect of mental care will exceed that of animal therapy, and we expect to provide care and welfare support in place of human beings

    Shaping Robot Gestures to Shape Users' Perception: the Effect of Amplitude and Speed on Godspeed Ratings

    This work analyses the relationship between the way robots gesture and the way those gestures are perceived by human users. In particular, this work shows how modifying the amplitude and speed of a gesture affect the Godspeed scores given to those gestures, by means of an experiment involving 45 stimuli and 30 observers. The results suggest that shaping gestures aimed at manifesting the inner state of the robot (e.g., cheering or showing disappointment) tends to change the perception of Animacy (the dimension that accounts for how driven by endogenous factors the robot is perceived to be), while shaping gestures aimed at achieving an interaction effect (e.g., engaging and disengaging) tends to change the perception of Anthropomorphism, Likeability and Perceived Safety (the dimensions that account for the social aspects of the perception)

    Humanoid Robots

    For many years, the human being has been trying, in all ways, to recreate the complex mechanisms that form the human body. Such task is extremely complicated and the results are not totally satisfactory. However, with increasing technological advances based on theoretical and experimental researches, man gets, in a way, to copy or to imitate some systems of the human body. These researches not only intended to create humanoid robots, great part of them constituting autonomous systems, but also, in some way, to offer a higher knowledge of the systems that form the human body, objectifying possible applications in the technology of rehabilitation of human beings, gathering in a whole studies related not only to Robotics, but also to Biomechanics, Biomimmetics, Cybernetics, among other areas. This book presents a series of researches inspired by this ideal, carried through by various researchers worldwide, looking for to analyze and to discuss diverse subjects related to humanoid robots. The presented contributions explore aspects about robotic hands, learning, language, vision and locomotion

    Designing companions, designing tools : social robots, developers, and the elderly in Japan

    Ce mémoire de maîtrise trace la généalogie d’un robot social, de sa conception à ses différentes utilisations et la manière dont les utilisateurs interagissent avec. A partir d’un terrain de six mois dans une start-up et deux maisons de retraite au Japon, j’interroge la création de Pepper, un robot social crée par la compagnie japonais SoftBank. Pepper a été créé de façon à être humanoïde mais pas trop, ainsi que perçu comme adorable et charmant. Par la suite, je décris comment Pepper et d’autres robots sociaux sont utilisés, à la fois par des développeurs, mais aussi par des personnes âgées, et je souligne une tension existante entre leur utilisation comme des compagnons et des outils. En me basant sur l’anthropologie ontologique et la phénoménologie, j’examine la construction du robot comme une entité avec laquelle il est possible d’interagir, notamment à cause de sa conception en tant qu’acteur social, ontologiquement ambigu, et qui peut exprimer de l’affect. En m’intéressant aux interactions multimodales, et en particulier le toucher, je classifie trois fonctions remplies par l’interaction : découverte, contrôle, et l’expression de l’affect. Par la suite, je questionne ces actes d’agir vers et s’ils peuvent être compris comme une interaction, puisqu’ils n’impliquent pas que le robot soit engagé. J’argumente qu’une interaction est un échange de sens entre des agents engagés et incarnés. Il y a effectivement parfois un échange de sens entre le robot et son utilisateur, et le robot est un artefact incarné. Cependant, seule l’impression d’intersubjectivité est nécessaire à l’interaction, plutôt que sa réelle présence.This master’s thesis traces a genealogy of a social robot through its conception to its various uses and the ways users interact with it. Drawing on six months of fieldwork in a start-up and two nursing homes in Japan, I first investigate the genesis of a social robot created by SoftBank, a Japanese multinational telecommunications company. This social robot is quite humanlike, made to be cute and have an adorable personality. While developers constitute one of the user populations, this robot, along with several others, is also used by elderly residents in nursing homes. By analyzing the uses of these populations, I underline the tension between the social robot as a companion and a tool. Drawing on ontological anthropology and phenomenology I look at how the robot is constructed as an entity that can be interacted with, through its conception as an ontologically ambiguous, social actor, that can express affect. Looking at multimodal interaction, and especially touch, I then classify three functions they fulfill: discovery, control, and the expression of affect, before questioning whether this acting towards the robot that does not imply acting from the robot, can be considered a form of interaction. I argue that interaction is the exchange of meaning between embodied, engaged participants. Meaning can be exchanged between robots and humans and the robot can be seen as embodied, but only the appearance of intersubjectivity is enough, rather than its actual presence

    In the last two decades, Tangible User Interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. Drawing upon users' knowledge and skills of interaction with the real non-digital world, TUIs show a potential to enhance the way in which people interact with and leverage digital information. However, TUI research is still in its infancy and extensive research is required in or- der to fully understand the implications of tangible user interfaces, to develop technologies that further bridge the digital and the physical, and to guide TUI design with empirical knowledge. This paper examines the existing body of work on Tangible User In- terfaces. We start by sketching the history of tangible user interfaces, examining the intellectual origins of this field. We then present TUIs in a broader context, survey application domains, and review frame- works and taxonomies. We also discuss conceptual foundations of TUIs including perspectives from cognitive sciences, phycology, and philoso- phy. Methods and technologies for designing, building, and evaluating TUIs are also addressed. Finally, we discuss the strengths and limita- tions of TUIs and chart directions for future research
