This work introduces a survey questionnaire about adult perceptions of privacy, attitudes, and comfort with robots in different spaces in the home. Additionally, in the survey, adult comfort was considered with the preconception that children would share information with robots and other third parties. As for the structure of the survey, it includes likert-style questions, multiple choice, and open responses for qualitative explanations of participant comfort in different situations. In this paper, we give more details about the survey, preliminary qualitative results, and suggestions for further use. We hope this work brings light to the importance of studying privacy concerns in the home with all family stakeholders.

Socially assistive robots can be used as therapeutic technologies to address depression symptoms. Through three sets of workshops with individuals living with depression and clinicians, we developed design guidelines for a personalized therapeutic robot for adults living with depression. Building on the design of Therabot™, workshop participants discussed various aspects of the robot’s design, sensors, behaviors, and a robot connected mobile phone app. Similarities among participants and workshops included a preference for a soft textured exterior and natural colors and sounds. There were also differences - clinicians wanted the robot to be able to call for aid, while participants with depression differed in their degree of comfort in sharing data collected by the robot with clinicians.CCS CONCEPTS• Human-centered computing → HCI design and evaluation methods; • Social and professional topics → User characteristics.

Participatory robot design projects with older adults often use multiple sessions to encourage design feedback and active participation from users. Prior projects have, however, not analyzed the learning outcomes for older adults across co-design sessions and how they support constructive design feedback and meaningful participation. To bridge this gap, we examined the learning outcomes within a "longitudinal panel." This panel comprised seven co-design sessions with 11 older adults of varying cognitive abilities over six months, aimed at designing a robot to guide a photograph-based conversational activity. Using Nelson and Stolterman’s framework of the hierarchy of design-learning, we demonstrate how older adult panelists achieved multiple design-learning outcomes – capacity, confidence, capability, competence, courage, and connection – which allowed them to provide actionable design suggestions. We provide guidelines for conducting longitudinal panels that can enhance user design-learning and participation in robot design.CCS CONCEPTS• Human-centered computing → Participatory design; User centered design; • Computer systems organization → Robotics; • General and reference → Design.

Robot designers commonly conceptualize robot sociality as a collection of features and capabilities. In contrast, sociologists define sociality as continuously constructed through interpersonal interactions. Based on the latter perspective, we trace how robots are incorporated into emerging social interaction ritual chains by robot companies and their staff and by robot owners across diverse contexts: homes, cafes, robot stores, user-organized meetups, and company events for robot users. Our empirical findings from ethnographic field work in Japan relating to three robots – aibo, RoboHon, and LOVOT – show how companies create positive interactions between people and robots by incorporating familiar design patterns into robots, modeling successful interactions in person and online, and bringing owners together in events that establish common values of acceptance of social robots as artifacts to live with and nurture. Owners, for their part, develop interaction rituals that include robots in their daily activities, make interpersonal connections, and experience emotionally resonant interactions, around robots in public meetups and events. Through these emerging interaction ritual chains, companies and owners construct the notion of robots as social agents to live with as a meaningful component of their emotional experiences and broader social relationships. Our work suggests that social robot design should consider this broader framing of sociality and create affordances for establishing interaction ritual chains more explicitly.CCS CONCEPTS • Human-centered computing → Empirical studies in HCI; Field studies; Empirical studies in interaction design; Interaction design theory, concepts and paradigms.

Though teens are a population with growing agency and use of smart technologies, their concerns surrounding privacy with AI and robots are under-represented in research. Using focus group discussions and a mixed methods analysis, we present teens’ comfort levels with robotic information collection and sharing during three hypothetical scenarios involving a child interacting with the Haru social robot in the home. We find participant concerns align with an access-based definition of privacy which prioritizes being in control of their information and of when the robot behaves autonomously. Responses also indicate that teens conceptualize Haru not just as an intelligent device, but also as a social entity. Their shifts in comfort and discussions reflect an engagement in social relationship management with robots in the home in cases where the robot mediates a user’s responsibilities and relationships with others.CCS CONCEPTS• Security and privacy → Social aspects of security and privacy; • Human-centered computing → User studies; • Social and professional topics → Adolescents.

As robots become increasingly active around human environments, they must navigate both physical and social realms, necessitating awareness of their surroundings and inhabitants, including the potential collection of sensitive data. To be accepted in human spaces, they need to be trusted to handle personal information adequately, not only adhering to security and data protection standards, but also aligning with contextual norms, individual expectations, and domain-specific requirements. Challenges intensify when robots engage with multiple humans across varied contexts over extended periods. Drawing from psychology, sociology, ethics, and law, and the experience of participants, we seek to outline dimensions and prerequisites for privacy-awareness in HRI. In this workshop we want to discuss methodologies, user interfaces, and personalizing options, and AI reasoning to design privacy-aware robot behavior in the human-robot interaction community.

One of the questions human-robot interaction (HRI) research needs to address prior to in-home robot deployment is when optimal moments for everyday interaction might occur. These can vary based on robot users' existing routines and personal preferences. As part of a larger project to design a conversational robot that can assist older adults in recognizing and maintaining their ikigai (sense of meaning and purpose in life), we explored the question "when might be good times for the robot to engage older adults in activities?". 11 older adults who were familiar with our prototype robot from prior participation in our research took part in a two week-long "diary study" to identify their habits and preferred times of engagement with the robot. The diary was performed by sending text messages to the older adults twice daily, asking what they were doing at the moment and whether this was a suitable time for interacting with the robot. The findings of the study allowed us to determine optimal times for interaction with the robot' - commonly before and after lunch and before sleep. Insights from this approach contribute to designing robots that can be integrated into the daily lives of older adults.

We explore the integration of a visual and thermal camera to approximate physiological changes as markers of cognitive load and child's engagement with a robot. The aim of our data pipeline is to enable non-invasive engagement tracking for a desktop social robot developed by Honda Research Institute named Haru. From utilizing these two cameras we can recognize engagement during child-robot interactions (CRI) using changes in nose-tip temperature. We tested our algorithm on data collected while a child participant interacted with Haru during a passive activity as well as an active activity. Then, we did a preliminary modeling of engagement with Hidden Markov models. This paper describes our experimental setup, our data collection, multi-modal pipeline, and some preliminary results from modeling the data.

Social robots are being studied for a wide variety of user populations, such as older adults, but programming these social robots typically requires deep technical knowledge. In this study, we developed a no-code end-user robot programming interface, with the goal of our interface being to empower individuals with no programming background to easily create social robot interactions with older adults using natural language. We evaluated five individuals with connections to adults older than 65 without robot programming experience. They were tasked with designing a simple conversation with the robot. We recorded their experiences using a survey and found that participants successfully used the interface to make the robot communicate with older adults. Overall, the participants found the interface easy to use and enjoyed the process. Thus, we provide recommendations on how to improve no-code end-user robot programming interfaces further.

A new design approach to discrete time sliding-mode-based controllers with disturbance compensation is proposed in this paper. The approach is applicable for linear time invariant plants with matched disturbances. Starting from the known methods for disturbance estimation (i) using discrete time nominal plant model and (ii) using original sliding mode control design method, full integration of those two algorithms into single one is proposed. Besides, the proposed algorithm can be additionally simplified for a small sampling time. The simplified algorithm does not directly depend on the equivalent control but only on the present and previous values of the sliding variable and previous value of the control. The obtained results are compared with the corresponding system with disturbance estimator based on sliding variable measurement. It is established that both methods give identical results in the nominal case. The method is illustrated in a positional servo system design. Comparative analysis of different methods is done by computer simulation.

Background Melanoma, a worldwide widespread skin cancer with over 325,000 yearly incidences, demands a thorough understanding of its molecular components to create effective therapeutics. This study looks at the PRAME (cutaneous melanoma-associated antigen) and BAP1 (gene controlling gene-environment interactions) proteins, which are important in melanoma development and are important for understanding the molecular landscape of melanoma. Introduction While playing a crucial role in melanoma, the structural and functional characteristics of PRAME and BAP1 remain unidentified. This work tries to unravel their complexities by investigating conserved residues, sequence invariance, and other molecular characteristics that contribute to their importance in melanoma. Promising therapeutic targets for melanoma therapy are identified by analyzing these proteins at the molecular level. Methods The study makes extensive use of bioinformatics methods to analyze PRAME and BAP1, including sequence conservation, inherent disorder, polyglutamic acid presence, and polarity alterations. Established approaches are used to investigate residue changes and their effects on protein folding, aggregation, and interactions. Results PRAME and BAP1 conserved residues highlight their critical roles in protein function and interaction. Sequence invariance indicates the possibility of functional relevance and evolutionary conservation. In intrinsically disordered proteins (IDPRs), PRAME has enhanced intrinsic disorder and flexibility, whereas BAP1 has changed disorder-promoting residue sequences. Polyglutamic acid strings are found in both proteins, emphasizing their modulatory involvement in protein interactions. Protein folding and aggregation are influenced by polarity shifts, with a balanced distribution of acidic and basic residues preserving native structures. The ratios and distributions of amino acids, particularly neutral residues, have a profound influence on interactions and gene dysregulation. Conclusion PRAME and BAP1 structural and functional understanding pave the way for diagnostic and tailored treatment options in melanoma. Differences in residue alterations, polarity distributions, and amino acid ratios provide intriguing drug design options. This research contributes to a better knowledge of melanoma-associated two proteins, opening the path for novel diagnostic and therapy techniques in skin cancer and beyond.

The decisions made by autonomous robots hold substantial influence over how humans perceive their behavior. One way to alleviate potential negative impressions of such decisions by humans and enhance human comprehension of them is through explaining. We introduce visual and textual explanations integrated into robot navigation, considering the surrounding environmental context. To gauge the effectiveness of our approach, we conducted a comprehensive user study, assessing user satisfaction across different forms of explanation representation. Our empirical findings reveal a notable discrepancy in user satisfaction, with significantly higher levels observed for explanations that adopt a multimodal format, as opposed to those relying solely on unimodal representations.

A notable advancement in fuzzy set theory is the q-rung linear diophantine fuzzy set. The soft set theory was expanded into the hypersoft set theory. By combining both the q-rung linear diophantine fuzzy set and hypersoft set, this study describes the notion of q-rung linear diophantine fuzzy hypersoft set that can handle multi sub-attributed q-rung linear diophantine fuzzy situations in the real world. Furthermore, some of its algebraic operations such as union, intersection and complement are described in this study. In addtion, the entropy measure of the q-rung linear diophantine fuzzy hypersoft set is established as it is helpful in determining the degree of fuzziness of q-rung linear diophantine fuzzy hypersoft sets. A multi-attribute decision making algorithm based on suggested entropy is presented in this study along with a numerical example of selecting a suitable wastewater treatment technology to demonstrate the effectiveness of the proposed algorithm in real-life situations. A comparative study was undertaken that describes the validity, robustness and superiority of the proposed algorithm and notions by discussing the advantages and drawbacks of existing theories and algorithms. Overall, this study describes a novel fuzzy extension that prevails over the existing ones and contributes to the real world with a valid real-life multi-attribute decision making algorithm that can cover many real-world problems that are unable to be addressed by the existing methodology.
