Though some matters of consensus have begun to crystallize, scholars in human-robot interaction have thus far reasoned about artificial identity under many different definitions. Many of these seemingly disparate perspectives may, however, be unified into one coherent model through a synthesis of contemporary scientific and Buddhist philosophy of identity. Under this model, artificial and human identity are modeled equivalently under an assumption that there is no &amp;quot;unchanging essence&amp;quot; which constitutes an agent&#39;s identity, but rather that identity may be defined as the sum of overlapping aggregates subject to change through time. The model reckons with the idea that much of what is conceived of as identity may be arbitrarily ascribed, artificial boundaries, but that these boundaries often constitute substantial social and psychological realities. This thinking is congruent with contemporary philosophical perspectives across disciplines from biology to cognitive science. The model may serve as a useful tool for reasoning about identity in complex, dynamic situations and provide a firm foundation for work which utilizes artificial identity. The model may even offer one or two possible answers to the question: Who is a robot?

Deploying robots in human-shared environments requires a deep understanding of how nearby agents and objects interact. Employing causal inference to model cause-and-effect relationships facilitates the prediction of human behaviours and enables the anticipation of robot interventions. However, a significant challenge arises due to the absence of implementation of existing causal discovery methods within the ROS ecosystem, the standard de-facto framework in robotics, hindering effective utilisation on real robots. To bridge this gap, in our previous work we proposed ROS-Causal, a ROS-based framework designed for onboard data collection and causal discovery in human-robot spatial interactions. In this work, we present an experimental evaluation of ROS-Causal both in simulation and on a new dataset of human-robot spatial interactions in a lab scenario, to assess its performance and effectiveness. Our analysis demonstrates the efficacy of this approach, showcasing how causal models can be extracted directly onboard by robots during data collection. The online causal models generated from the simulation are consistent with those from lab experiments. These findings can help researchers to enhance the performance of robotic systems in shared environments, firstly by studying the causal relations between variables in simulation without real people, and then facilitating the actual robot deployment in real human environments.<br> ROS-Causal: https://lcastri.github.io/roscausal

Experimental Evaluation of ROS-Causal in Real-World Human-Robot Spatial Interaction Scenarios

As collaborative robots become more common in manufacturing scenarios and adopted in hybrid human-robot teams, we should develop new interaction and communication strategies to ensure smooth collaboration between agents. In this paper, we propose a novel communicative interface that uses Mixed Reality as a medium to perform Kinesthetic Teaching (KT) on any robotic platform. We evaluate our proposed approach in a user study involving multiple subjects and two different robots, comparing traditional physical KT with holographic-based KT through user experience questionnaires and task-related metrics.

Kinesthetic Teaching in Robotics: A Mixed Reality Approach

Recently, electroencephalographic (EEG) signals have been used to enhance Human-Robot Interaction (HRI). In particular, Error-Related Potentials (ErrPs) have been exploited since very few years. These potentials are evoked when there is a mismatch between the command given by the subject and the movements of the robot, or if the users expectation is different from the robot or other human behavior. These signals can be used to improve and customize the robot system, as feedback to better adapt the robot to human needs. This work aims to investigate and detect the ErrPs during different interaction tasks. We set up an experiment divided into five different tasks, where every task has 120 events with a 25%- 35% probability of error. The robot used in the experiment is a Baxter robot and the commands from the subject to the robot are sent in two different ways: with a keyboard or with a motion capture device. This work aims to reproduce a simplified teleoperated pick and place task. However, the achieved results do not allow to correctly identify the ErrPs, but exhibit only some minor differences between trials with and without errors. Hence, we here analyze the reasons behind such negative results, focusing on the challenges of the structure and the setup of the experiment. We analyze the possible problems and provide some recommendations to overcome them in similar use cases.

Challenges in Detecting and Analyzing EEG Error-Related Potentials: Lessons from a Case Study in HRI

Using socially assistive robots (SARs) as specialized companions for those living with depression to manage symptoms provides a unique opportunity for exploration of robotic systems as comfort objects. Moreover, the robotic components allow for specialized behavioral responses to particular stimuli, as preferred by the user. We have conducted semi-structured interviews with 10 participants about the zoomorphic robots Therabot desired behaviors and focus groups with five additional participants regarding the preferred sensors within the Therabot system. In this paper, using the data from interviews and focus groups, we explore SAR input and output for depression management. While participants overall expected the robot to respond in much similar ways as a well-trained service animal, they expressed interest in the robot understanding unique information about the environment and the user, such as when the user might need interaction.

The Ins and Outs of Socially Assistive Robots: Sensors and Behaviors of a Therapeutic Robot for Depression Management

The global aging population is growing, leading to an increased need for unpaid carers to support older adults. Socially Assistive Robots (SARs) can play an important role in supporting unpaid carers. However, as with any socio-technical system, building and maintaining trust is critical for achieving full potential and adoption of a SAR. Despite the growing interest in robotics across various domains, there has been limited research on time-dependant patterns of trust during Human Robot Interactions (HRI) and how unpaid carers perceive SARs as a support tool for care. We present a study in which we a) investigate the level of trust that unpaid carers have in using SARs for taking care of older adults, b) qualitatively explore the factors that influence trust considering the dynamic and context dependant nature of care. To explore SARs as a support tool from the perspective of unpaid carers we recruited 15 caregivers, we conducted co-design sessions, interviews and carers interacted with a Pepper robot evaluating trust before and after interaction. We discuss how the level of trust of unpaid carers in SARs increases after interaction and how unpaid carers trust in SARs is impacted by socially and culturally intelligent robots. Our work contributes to identify factors influencing trust that are important for carers while interacting with SARs, offering insights for the development and implementation of future SAR-based as a support tool that can assist them in taking care of older adults.

An Exploratory Analysis of Trust in Socially Assistive Robot Interactions with Unpaid Carers of Older Adults

Engaging in regular exercise offers numerous mental and physical health benefits. Many people, after the Covid-19 pandemic, started to work out at home. However, performing exercises incorrectly can result in injuries. For this reason, technology can be an effective tool for encouraging physical activity at home, and social robots have emerged as a potential solution for providing fitness training in a safe and engaging manner. A physical robot is often perceived as more socially attractive compared to virtual agents. Despite the growing popularity and existing literature on social robotics-based fitness solutions, there is a lack of research examining the accuracy of these systems and interventions at home during physical exercise recognition.In this paper, we propose a novel approach utilizing the Ubtech alpha mini social robot, which possesses motor capabilities to demonstrate exercises. We endowed the robot with the capability to recognize exercise correctness and motivate users to engage in physical activities. In this project, first of all, a new dataset of physical exercises was created, including 1,500 videos of physical exercises. Then, a new approach to recognize physical exercises from image sequences was presented. This method was implemented in a personal social robot to recognize physical exercises using a deep learning model. The results of the study validate the effectiveness of the system in recognizing physical exercises through the camera onboard a personal social robot.

With the increase of prevalence in autism, the need for efficient public health support has been amplified. Socially-assistive robots (SARs) have been found effective in engaging and interacting with autistic children, however, the perception intelligence during interaction still needs more domain-specific knowledge in terms of understanding children's behaviors. The Family Observation Schedule-Second Version (FOS-II) is one of the key methods in assessing parent-child interactions in developmental disabilities, yet its manual annotation demands considerable time and effort. This study proposes a multi-modal artificial intelligence (AI) model using video and audio inputs for automated FOS-II annotation. Utilizing advanced deep learning for behavior recognition, this method offers rapid, cost-effective FOS-II scaling. It will thus enhance the capability of socially assistive robots to understand human behaviors and support the advancement of digital health research for children with autism. The visual perception in home settings are most likely based on uncontrolled environments, so it is crucial to develop algorithms that can robustly work with video-log data with uncontrolled quality. Ultimately, it aims to ease the burden on parents and caregivers, streamlining the monitoring and treatment of challenging behaviors in autism.

This qualitative study explored 20 grade 3-5 childrens perceptions of learning STEM vocabulary with an educational social robot. A semi-structured interview protocol was used to elicit childrens perceptions. Interviews were recorded and transcribed into a database reflecting one talk-turn per row (911 talk-turns total). Two coders used emergent coding and constant comparative method to identify talk-turns that reflected childrens perceptions of the assets and drawbacks of learning STEM vocabulary with the robot. Findings identified new assets and drawbacks about the robots instruction, and new drawbacks about the robots speech, which were not explored in previous research. Findings suggest design implications, including designing robots with the capacity for more individualization of instruction and adjustable movement and speech features based on learners preferences.

This study investigates how the level of physical anthropomorphism in conversational agents affects their persuasiveness. The experiment compared robots with low and high levels of anthropomorphism, akin to human appearance. Results indicated that while sophisticated physical embodiment did not universally enhance persuasiveness, it did have an interaction effect based on issue involvement. For low involvement issues, persuasiveness increased with higher anthropomorphism. In contrast, for high involvement issues, persuasiveness remained constant across different levels of anthropomorphism but dropped when robots closely resembled humans, possibly due to trust in high-tech robots. The findings highlight the importance of digital agents persuasive power and ethics in employing and designing robots.

The Impact of Physical Anthropomorphism in Social Robots on User Compliance: The Moderating Effect of Issue Involvement

The seamless integration and acceptance of humanoid service robots in society requires a general understanding of those robots. An overall transparent design can be a means to establish this. To guide the implementation of effective transparency mechanisms, we propose the novel Transparency Design Model, which builds on the concept of Interaction Transparency from our previous work. This model encompasses a wide range of transparency aspects aimed to improve the overall transparency of humanoid service robot designs. To demonstrate the applicability of our model and gather initial insights on its impact on robot perception, we conducted a user study involving 50 participants. The study compared a neutral and transparent robot behavior within a complex sales service scenario. Our findings indicate that the transparent design significantly improve the robots likeability, anthropomorphism, and benevolence. Additionally, we observed positive trends in attractiveness, stimulation, and novelty as measured by the User Experience Questionnaire. These measurable effects highlight the important role of Interaction Transparency. The results also imply that a holistic system analysis in multiple complex and application-dependent interactions is worthwhile as the service content influences the perception and effects of the individual design steps. Further, there is a need to develop a new scale for measuring Interaction Transparency. Lastly, future research could benefit from employing multi-modal assessment tools.
