From Embodied Abuse to Mass Disruption : Generative, Inter-Reality Threats in Social, Mixed-Reality Platforms

Extended Reality (XR) platforms can expose users to novel attacks including embodied abuse and/or AI attacks-at-scale. The expanded attack surfaces of XR technologies may expose users of shared online platforms to psychological/social and physiological harms via embodied interactions with potentially millions of other humans or artificial humans, causing what we define as an inter-reality attack. The past twenty years have demonstrated how social and other harms (e.g. bullying, assault and stalking) can and do shift to digital social media and gaming platforms. XR technologies becoming more mainstream has led to investigations of ethical and technical consequences of these expanded input surfaces. However, there is limited literature that investigates social attacks, particularly toward vulnerable communities, and how AI technologies may accelerate generative attacks-at-scale. This paper employs human-centred research methods and a harms-centred Cybersecurity framework to co-design a testbed of socio-technical attack scenarios in XR social gaming platforms. It uses speculative fiction to further extrapolate how these could reach attacks-at-scale by applying generative AI techniques. It develops an Inter-Reality Threat Model to outline how actions in virtual environments can impact on the real-world. As AI capability continues to rapidly develop, this paper articulates the urgent need to consider a future where XR-AI attacks-at-scale could become commonplace.

How Should Clinician-Researchers Model Regard for Nonhuman Animals Bred for and Used in Human-Centered Science?

If we assume that nonhuman animals experience pain or distress, then ethically justifying human-centered research with only nonhuman animals as subjects likely requires that the research's benefits to humans must, at least, outweigh harms suffered by the nonhuman animals. Yet this reasoning does not seem to account well for the ethical view that nonhuman animals are morally valuable in their own right. This commentary on a case considers this ethical tension and discusses how clinician-researchers should navigate it. This commentary also suggests why clinician-researchers' reasoning about the nature and scope of their obligations to nonhuman animals extends beyond governing regulations and federal oversight, which is silent on or ambiguous about nonhuman animals as morally valuable in their own right.

Parallel intelligence in three decades: a historical review and future perspective on ACP and cyber-physical-social systems

Recent advances in human-in-the-loop or human-centric research have sparked a new wave of scientific exploration. These studies have enhanced the understanding of complex social systems and contributed to more sustainable artificial intelligence (AI) ecosystems. However, the incorporation of human or social factors increases system complexity, making traditional approaches inadequate for managing these complex systems and necessitating a novel operational paradigm. Over decades of work, a mature and comprehensive theory of parallel intelligence (PI) has been established. Rooted in cyber-physical-social systems (CPSS), PI adapts flexibly to various situations within complex systems through the ACP framework (Artificial systems, Computational experiments, and Parallel execution), ensuring system reliability. This paper provides a detailed review and a novel perspective on PI, beginning with the historical and philosophical origins of CPSS and proceeding to present both the fundamental framework and technological implementations of PI. PI-based Industry 5.0 is highlighted, where three pillars are adopted to help realize the supposed vision. Additionally, the paper outlines applications of PI in multiple fields, such as transportation, healthcare, manufacturing, and agriculture, and discusses the opportunities and challenges for imaginative intelligence. The continuous exploration of PI is expected to eventually facilitate the realization of “6S”-based (safe, secure, sustainable, sensitive, service, and smart) parallel ecosystems.

Ten questions concerning statistical data analysis in human-centric buildings research: A focus on thermal comfort investigations

Given the large amount of time we spend indoors, designing and operating buildings that are safe, comfortable, and conducive to productivity and well-being is essential. To achieve this goal, in the past decades, research has been conducted to investigate the influence of the indoor environment on occupants. Thermal comfort has been the subject of most investigations in this field. However, despite being a consolidated research topic since the 1920s, statistical practices for analysing thermal comfort data often rely on simplified premises, which may be due to several possible factors (e.g., limited computational capabilities and lack of training). Consequently, important aspects of data analysis are often absent or overlooked. Recent statistics and statistical software advances have provided more options for effectively modelling complex issues. However, properly using these tools requires a solid understanding of statistical analysis, increasing the risk of misuse in practice. This paper presents ten questions highlighting the most critical issues regarding statistical analysis for thermal comfort research and practice. The first four questions provide general perspectives concerning statistical data analysis, while the remaining ones address specific problems related to thermal comfort research, but that can extend to all human-centric research in the built environment. Additionally, the last five questions demonstrate the practical significance of analysis pitfalls (i.e., sampling variability, selection bias, variable selection, clustered/nested observations, and measurement error) through examples with synthetic data. This study provides insights into the current statistical ‘habits’ in thermal comfort research and, more importantly, help researchers better define and conduct their statistical analyses.

Digital Mental Health for Schizophrenia and Other Severe Mental Illnesses: An International Consensus on Current Challenges and Potential Solutions.

Digital approaches may be helpful in augmenting care to address unmet mental health needs, particularly for schizophrenia and severe mental illness (SMI). An international multidisciplinary group was convened to reach a consensus on the challenges and potential solutions regarding collecting data, delivering treatment, and the ethical challenges in digital mental health approaches for schizophrenia and SMI. The consensus development panel method was used, with an in-person meeting of 2 groups: the expert group and the panel. Membership was multidisciplinary including those with lived experience, with equal participation at all stages and coproduction of the consensus outputs and summary. Relevant literature was shared in advance of the meeting, and a systematic search of the recent literature on digital mental health interventions for schizophrenia and psychosis was completed to ensure that the panel was informed before the meeting with the expert group. Four broad areas of challenge and proposed solutions were identified: (1) user involvement for real coproduction; (2) new approaches to methodology in digital mental health, including agreed standards, data sharing, measuring harms, prevention strategies, and mechanistic research; (3) regulation and funding issues; and (4) implementation in real-world settings (including multidisciplinary collaboration, training, augmenting existing service provision, and social and population-focused approaches). Examples are provided with more detail on human-centered research design, lived experience perspectives, and biomedical ethics in digital mental health approaches for SMI. The group agreed by consensus on a number of recommendations: (1) a new and improved approach to digital mental health research (with agreed reporting standards, data sharing, and shared protocols), (2) equal emphasis on social and population research as well as biological and psychological approaches, (3) meaningful collaborations across varied disciplines that have previously not worked closely together, (4) increased focus on the business model and product with planning and new funding structures across the whole development pathway, (5) increased focus and reporting on ethical issues and potential harms, and (6) organizational changes to allow for true communication and coproduction with those with lived experience of SMI. This study approach, combining an international expert meeting with patient and public involvement and engagement throughout the process, consensus methodology, discussion, and publication, is a helpful way to identify directions for future research and clinical implementation in rapidly evolving areas and can be combined with measurements of real-world clinical impact over time. Similar initiatives will be helpful in other areas of digital mental health and similarly fast-evolving fields to focus research and organizational change and effect improved real-world clinical implementation.

Understanding Inclusivity in Online Learning from a Socio-material Lens

The global pandemic in 2020 has led to a recent rise of digital technologies in higher education internationally, which seems to make learning less restricted in terms of time and space (Oztok, 2019) and enhance inclusion and engagement in learning. However, it is necessary to distinguish the presence and interaction in online learning from true connectedness and inclusivity. Networked learning, as a concept being constantly explored by a small group of researchers since the 1990s and attracting increasing current attention, is built around the different kinds of connections between students and instructors, as well as human and non-humans (NLEC, 2021). This paper emphasizes the need to be aware of the dimension of connection constructed through the assemblage of humans, materials and discourses. Adopting a socio-material perspective, the assumed high accessibility of online learning and the neo-liberal discourse of a ‘good learner’ are challenged and care is proposed as an approach to improve inclusivity in online learning in higher education. This paper is drawn from the data of a comparative research study that explores the online learning experience of undergraduate students in one case study university in China and the UK respectively. The research consisted of qualitative interviews with students and academics in the case discipline Sociology. The findings suggest a mismatch between students’ and teachers’ perception of what makes effective engagement. Although the teachers recognise certain difficulties in online courses, such as technical issues for organizing small group discussions, arguably the implied neo-liberal message is that hard-working ‘good’ students will always participate, regardless of where or how they learn. However, interviews with students in both contexts show that the specific surroundings in formal and informal educational settings, the interaction and support from peers, and the way their status is recognised in the community concomitantly mediate their experience, in addition to their abilities or motivation. This research contributes by highlighting the potential of emergent forms of networked learning in terms of unveiling the issues of established discourses including neoliberalism. It provides suggestions for future practices by proposing the role of care, supported by the findings, in tackling disengagement and exclusion, and pivoting students around supportive learning. Further, it adopts a socio-material perspective that fills a gap created by the dominance of human-centred research, generating reflections on the use of online materials in higher education.

"It's the most fair thing to do but it doesn't make any sense": Perceptions of Mathematical Fairness Notions by Hiring Professionals

We explore the alignment of organizational representatives involved in hiring processes with five different, commonly proposed fairness notions. In a qualitative study with 17 organizational professionals, for each notion, we investigate their perception of understandability, fairness, potential to increase diversity, and practical applicability in the context of early candidate selection in hiring. In this, we do not explicitly frame our questions as questions of algorithmic fairness, but rather relate them to current human hiring practice. As our findings show, while many notions are well understood, fairness, potential to increase diversity and practical applicability are rated differently, illustrating the importance of understanding the application domain and its nuances, and calling for more interdisciplinary and human-centered research into the perception of mathematical fairness notions.

APRD: action partnership research design: reimagining the role of the user in library and information science research

PurposeResponding to the continuing separation of participants and researchers in LIS participatory research, a new methodology is proposed: action partnership research design (APRD). It is asserted that APRD can mitigate or remove the hierarchical structures often inherent in the research process, thus allowing for equal contribution from all.Design/methodology/approachBuilding on the bonded design (BD) methodology and informed by a scoping literature review conducted by the same authors, APRD is a human-centered research approach with the goal of empowering and valuing community partnerships. APRD originates from research investigating the use of participatory design methods to foster collaboration between two potentially disparate groups, firstly with adult researchers/designers and elementary school children, and secondly with university faculty and IT professionals.FindingsTo achieve this goal, in addition to BD techniques, APRD draws inspiration from elements of indigenous and decolonization research methodologies, particularly those with an emphasis on destabilizing power hierarchies and involving research participants as full partners.Originality/value APRD, which emerged from findings from previous participatory design studies, especially those of BD, is based on the premise of partnership, recognizing that each member of a design team, whether researcher or participant/user, has unique expertise to contribute. By considering participants/users as full research partners, APRD aims to flatten the hierarchies exhibited in some LIS participatory research methodologies, where participants are treated more like research subjects than partners.

The Convergence of Ikigai and Design Thinking: Crafting a Purposeful Framework

In an era where innovation is not just about solving problems but also about enhancing human experiences and fostering personal fulfillment, the convergence of Ikigai principles with Design Thinking methodology offers a promising avenue for holistic problem-solving and innovation. This paper explores the intersection of Ikigai—a Japanese concept representing one's reason for being—and Design Thinking—a human-centered approach to innovation. We propose a conceptual framework, termed Ikigai-Driven Design (IDD), which integrates the principles of Ikigai with the stages of Design Thinking. IDD comprises five main stages: Empathize, Define, Ideate, Prototype, and Test, each combining elements of Ikigai and Design Thinking to foster purposeful innovation. The Empathize stage emphasizes understanding what users love and what the world needs, drawing insights from human-centered research methods. In the Define stage, practitioners frame problems through the lens of Ikigai, aligning identified needs with their own passions and strengths. The Ideate stage encourages divergent thinking, leveraging practitioners' Ikigai to generate creative solutions. Prototypes created in the Prototype stage embody practitioners' purpose and values, tested and refined based on user feedback in the Test stage. By integrating Ikigai principles with Design Thinking methodology, IDD offers a structured yet flexible approach to innovation that resonates deeply with users and contributes to practitioners' sense of fulfillment and meaning.

A human-centred review on maritime autonomous surfaces ships: impacts, responses, and future directions

ABSTRACT Maritime autonomous surface ships (MASS) are transforming the future of maritime transport. They are expected to shoulder important roles in seaborne trade and maritime resilience. As the primary operator of traditional ships and a significant component of maritime transport, seafarers are inevitably directly and indirectly affected by levels of automation introduced into the shipping space. Therefore, in addition to increasing attention to automated system designs, a holistic understanding of human elements in MASS operations is necessary. The current research (1) reviews human-centred MASS research, (2) categorises MASS impacts on seafarers, and (3) summarises responses to prepare seafarers for this emerging technology. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, a total of 101 articles were collected from Scopus. The systematic review reveals that MASS impacts seafarers from the following dimensions: employment, task contents, requisite skills, and human risks. Moreover, regulations and education frameworks can be adapted to respond to changes in seafarer demand and supply. Future research directions are also proposed and can serve as recommendations for future human-centred research on MASS. The research findings enhance the understanding of seafarer elements in MASS operations and provide policy implications for future seafarer management.

Advancements in therapeutic development: kidney organoids and organs on a chip

The use of animal models in therapeutic development has long been the standard practice. However, ethical concerns and the inherent species differences have prompted a reevaluation of the experimental approach in human disease studies. The urgent need for alternative model systems that better mimic human pathophysiology has led to the emergence of organoids, innovative in vitro models, to simulate human organs in vitro. These organoids have gained widespread acceptance in disease models, and drug development research. In this mini-review, we explore the recent strides made in kidney organoid differentiation and highlight the synergistic potential of incorporating organ-on-a-chip systems. The emergent use of microfluidic devices reveals the importance of fluid flow in the maturation of kidney organoids and helps decipher pathomechanisms in kidney diseases. Recent research has uncovered their potential applications across a wide spectrum of kidney research areas, including hemodynamic forces at stake in kidney health and disease, immune cell infiltration, or drug delivery and toxicity. This convergence of cutting-edge technologies not only holds promise for expediting therapeutic development but also reflects an acknowledgment of the need to embrace innovative and more human-centric research models.

Making Service Design Future-Proof at NASA

How can service designers create services that simultaneously address customer needs both today and in the future? Using a new method called ‘triangulated recursive mapping’ to combine futures research with human-centred research, we learn to create services that are responsive to rapidly evolving customer needs over time.

Aerobic Exercise and Neuropathic Pain: Insights from Animal Models and Implications for Human Therapy.

This narrative review explores the complex relationship between aerobic exercise (AE) and neuropathic pain (NP), particularly focusing on peripheral neuropathies of mechanical origin. Pain, a multifaceted phenomenon, significantly impacts functionality and distress. The International Association for the Study of Pain's definition highlights pain's biopsychosocial nature, emphasizing the importance of patient articulation. Neuropathic pain, arising from various underlying processes, presents unique challenges in diagnosis and treatment. Our methodology involved a comprehensive literature search in the PubMed and SCOPUS databases, focusing on studies relating AE to NP, specifically in peripheral neuropathies caused by mechanical forces. The search yielded 28 articles and 1 book, primarily animal model studies, providing insights into the efficacy of AE in NP management. Results from animal models demonstrate that AE, particularly in forms like no-incline treadmill and swimming, effectively reduces mechanical allodynia and thermal hypersensitivity associated with NP. AE influences neurophysiological mechanisms underlying NP, modulating neurotrophins, cytokines, and glial cell activity. These findings suggest AE's potential in attenuating neurophysiological alterations in NP. However, human model studies are scarce, limiting the direct extrapolation of these findings to human neuropathic conditions. The few available studies indicate AE's potential benefits in peripheral NP, but a lack of specificity in these studies necessitates further research. In conclusion, while animal models show promising results regarding AE's role in mitigating NP symptoms and influencing underlying neurophysiological mechanisms, more human-centric research is required. This review underscores the need for targeted clinical trials to fully understand and harness AE's therapeutic potential in human neuropathic pain, especially of mechanical origin.

Low-cost carbon dioxide concentration sensors for assessing air quality in the built environment: an on-site evaluation of their measurement performance

Carbon dioxide (CO2) concentration is commonly used to determine indoor air quality. However, wearable environmental monitoring devices have not considered CO2 content, because they have mainly focused on the outdoor environment. Our goal is to develop a new wearable monitoring system for indoor research purposes that also incorporates a CO2 concentration sensor. We evaluated the performance of two low-cost CO2 sensors, the Senseair K30 and the Sensirion SCD30, by comparing them with a professional reference sensor in two different environments: a Test Cell and the LabZEB of ITC-CNR. A first result shows that both low-cost sensors have acceptable performance, with the K30 showing a trend closer to that of the professional reference sensor and better overall performance. For this reason, we conducted a third test in which we encapsulated the selected K30 low-cost sensor in a 3D-printed, wearable housing that supports the sensor and control unit to see if the 3D-printed part could affect measurement performance. The result shows no interference in measurement performance. This suggests that low-cost sensors can be used in a wearable system to assess indoor air quality for environmental and human-centered research in the built environment.

A Morphological Analysis of Ergonomic Design Reconfigurations for Crutch Versatility in the Environment of Use

Nowadays, there are complications in the environments where the crutch is being used, which cause discomfort for users throughout the use and therapy period. There are many flaws in cities’ infrastructure. Using a simple search on the internet, it can be claimed that standard crutches have an array of design faults and ergonomic problems, and users seek to fix the problems with non-industrial solutions and home treatments. For this reason, various accessories for crutches are being produced, and even designers have proposed new types of crutches as replacements. However, the majority of them still didn’t pass the human-centered research procedure.

Multilingual News Search—A Comparative User Study of Desktop and Mobile Interfaces

With the global expansion of the Internet and the World Wide Web, users are becoming increasingly diverse, including their language proficiencies. In particular, there is now a significant number of polyglot Web users, i.e., users who are proficient in more than one language. However, even such users with potential access to a broad range of information from multiple languages often continue to suffer from unbalanced and fragmented news information, as traditional news access systems seldom allow users to simultaneously search for and/or compare news in different languages. To overcome language barriers, the majority of research has focused primarily on improving retrieval and translation accuracy, while paying comparably less attention to multilingual user interaction aspects. In particular, relatively little human-centered research has been conducted to better understand and support multilingual user abilities and preferences, and even less so regarding news search and different access modalities (such as desktop and mobile interfaces). The research presented in this article provides the first comparative analyses of polyglot users’ preferences and behaviors with respect to different multilingual news search interfaces on both desktop and mobile platforms. Specifically, through a set of task-based user studies in laboratory experiments, the key contribution of this article is the presentation of the first human-centered studies in multilingual news search result interfaces, aiming to drive the development of human-centered multilingual news access systems for both desktop and mobile platforms. This contribution includes a detailed analysis of different interface design paradigms, as well as a series of implications for design.

A review on ergonomics evaluations of virtual reality.

Virtual reality (VR) is a combination of technologies that allow the user to interact with a computer-simulated environment with the experience of immersion, interactivity, and imagination. However, ergonomic problems related to virtual reality have adverse effects on the health and experience of users, which restrict the application of virtual reality technology. The paper aims to provide an overview of the ergonomics evaluation of VR for further development of software and hardware of VR. This paper describes and discusses the ergonomics issues involved in the software and hardware of VR from three aspects: visual, physiological, and cognitive. The paper also summarizes the research methods and evaluation metrics. Many attempts have been made to study ergonomics issues of VR, mainly including pressure, muscle fatigue, thermal comfort, visual fatigue, and motion sickness. Ergonomics studies are very valuable for research related to virtual reality. There is a summary table that lists the main evaluation metrics and methods. According to current research, this review gives three recommendations for further research on VR, which will be helpful for further human-centered research and design work within the VR industry.

Addressing menstrual stigma through sex education in England- taking a sociomaterial turn

ABSTRACT Menstruation and menstrual stigma have recently attracted the attention of education policymakers in England. In 2019, the Department for Education (DfE) published new guidance on delivering relationships, sex and health education that included teaching about menstrual wellbeing and in 2020 made menstrual products freely available in all state-funded primary and secondary schools in England. The DfE argue that these dual interventions are important for tackling menstrual stigma by normalising menstruation in school. However, these interventions emphasise the management of menstruation in terms of physical health while this article argues that foregrounding how menstruation features in young people’s everyday experiences and routines could also be important for addressing stigma. This theory-focussed paper invites a turn away from a humanist positioning on menstruation and menstrual stigma. It discusses existing human-centred research on menstruation and draws on ideas from relational sociomaterial theory to highlight how researching the role of material things in young people’s engagements with menstruation can influence understandings about menstrual stigma and young people.

A Full Assistance System (FAS) for the Safe Use of the Tractor’s Foldable Rollover Protective Structure (FROPS)

The use of agricultural tractors is a major concern in agriculture safety due to the high level of risk of loss of stability combined with the frequent absence of passive safety devices such as rollover protective structures (ROPSs). Indeed, although in most cases the ROPS is installed, when working in vineyards, orchards, or in other cases of limited crop height, the tractor is usually equipped with a foldable ROPS (FROPS), which is often misused because the effort needed for raising/lowering is excessive and the locking procedure is time-consuming. Thus, the goal of this research is to investigate the problem from the ergonomics point of view, developing a support system capable of facilitating FROPS operations. The research outcome consists of the development of a retrofitted full assistance system (FAS) for lowering/raising the FROPS by means of electric actuators. Additionally, an automatic locking device (ALD) was also developed to safely and automatically lock the FROPS. Both the FAS and ALD systems were implemented following a reverse-engineering approach, while their final validation was performed by means of a real prototype tested in a laboratory. The results achieved can contribute to expanding knowledge on human-centered research to improve safety in agriculture and thus social issues of sustainable agricultural systems.
