We present a tangible origami-based artefact designed to explore how artefacts can foreground ecological entanglements by embodying movement, fragility, and responsiveness. Drawing on a Research through Design (RtD) practice-led approach using a diffractive lens rooted in new materialist philosophy, and inspired by expressive and defensive behaviours in plants and animals, the artefact combines rhythmic “breathing” actuation, colour change, and contraction to evoke a sense of aliveness and ambiguity. We contribute the design of a diffractive, tangible origami artefact intended to evoke aliveness and artefact agency, and a design process demonstrating diffraction as a generative lens for more-than-human HCI.

Online communities serve as essential support channels for People Who Use Drugs (PWUD), providing access to peer support and harm reduction information. The moderation of these communities involves consequential decisions affecting member safety, yet existing sociotechnical systems provide insufficient support for moderators. Through interviews with experienced moderators from PWUD forums on Reddit, we examine the unique nature of this work and its implications for HCI and content moderation research. We demonstrate that this work constitutes a distinct form of public health intervention characterised by three challenges: (1) high-stakes risk evaluation requiring pharmacological expertise, (2) time-critical crisis intervention spanning platform content and external drug market surveillance, and (3) navigation of structural conflicts where platform policies designed to minimise legal liability directly oppose community harm reduction goals. Our findings extend existing HCI moderation frameworks by revealing how legal liability structures can systematically undermine expert moderators' protective work, with implications for other marginalised communities facing similar regulatory tensions, including abortion care and sex work contexts. We identify two necessary shifts in sociotechnical design: moving from binary classification to multi-dimensional approaches that externalise competing factors moderators must balance, and shifting from low-level rule programming to high-level example-based instruction. However, we surface unresolved tensions around volunteer labour sustainability and risks of incorporating automated systems in high-stakes health contexts, identifying open questions requiring HCI research attention. These findings inform the design of platforms that better accommodate vulnerable populations whose health needs conflict with regulatory frameworks.

Alongside the benefits of a world in which more and more things are internet connected (i.e., the IoT), scaffolded by increasingly powerful AI systems, there is a growing recognition of a flipside to this vision of the future. Issues associated with privacy, transparency, legibility and trust have been widely recognized – which the Mozilla Foundation has encapsulated in their Internet Health Reports [13]. This workshop will explore these tensions and concerns through the lens of craft, both as a practice and a conceptual ethos. We will use embroidery as a craft-oriented ‘thinking through making’ activity as the foundation for discussions of our craft characteristics of which consist of; bespokeness, localism, embodiment, provenance, authenticity, and care. Participants will gain a rich understanding of debates around IoT while being engaged in a ‘thinking through doing’ embodied approach to gaining new insights and leave with their own hand embroidered badge.

Prototypes and other ‘things’ have had many uses in HCI research—to help understand a problem, as a stepping stone towards a solution, or as a final outcome of a research process. However, within the messy context of a research through design project, many of these roles do not form part of the final research narratives, restricting the ability of other researchers to learn from this practice. In this paper we revisit prototypes used in three different design research projects, conducted over a period when the Internet of Things emerged into everyday life, exploring complex hidden relationships between the internet, people and physical objects. We aim to explore the unreported roles that prototypes played in these projects, including brokering relationships with participants and deconstructing opaque technologies. We reflect on how these roles align with existing understandings of prototypes in HCI, with particular attention to how these roles can contribute to design around IoT.

We present a video-analysis study of museum visitors’ interactions at two tangible interactive exhibits in a transport museum. Our focus is on groups’ social and shared interactions, in particular how exhibit setup and structure influence collaboration patterns. Behaviors at the exhibits included individuals focusing beyond their personal activity towards companions’ interaction, adults participating via physical interaction, and visitors taking opportunities to interact when companions moved between sections of the exhibit or stepped back from interaction. We demonstrate how exhibits’ physical configuration and interactive control engendered behavioral patterns. Systematic analysis reveals how different configurations (concerning physical-spatial hardware and interactive software) distribute control differently amongst visitors. We present four mechanisms for how control can be distributed at an interactive installation: functional, temporal, physical and indirect verbal. In summary, our work explores how mechanisms that distribute control influence patterns of shared interaction with the exhibits and social interaction between museum visitor companions.

Emerging technologies---such as the voice enabled internet---present many opportunities and challenges for HCI research and society as a whole. Advocating for better, healthier implementations of these technologies will require us to communicate abstract values, such as trust, to an audience that ranges from the general public to technologists and even policymakers. In this paper, we show how a combination of film-making and product design can help to illustrate these abstract values. Working as part of a wider international advocacy campaign, Our Friends Electric focuses on the voice enabled internet, translating abstract notions of Internet Health into comprehensible digital futures for the relationship between our voice and the internet. We conclude with a call for designers of physical things to be more involved with the development of trust, privacy and security in this powerful emerging technological landscape.

Hackathons have become a popular tool for bringing people together to imagine new possibilities for technology. Despite originating in technology communities, hackathons have now been widely adopted by a broad range of organisations. This mainstreaming of hackathons means they encompass a very different range of attendees and activities than they once did, to the extent that some events billed as hackathons may involve no coding at all. Given this shift away from production of code, they might instead be seen as an increasingly popular participatory design activity, from which designers and researchers in HCI can learn. Through fieldwork at six hackathons that targeted non-technical communities, we identify the types of activities and contributions that emerge through these events and the barriers and tensions that might exist. In doing so, we contribute a greater understanding of hackathons as a growing phenomenon and as a potential tool for participatory research.

Despite widespread interest in civic technologies, empowering neighbourhoods to take advantage of these technologies in their local area remains challenging. This paper presents findings from the Ardler Inventors project, which aimed to understand how neighbourhoods can be supported in performing roles normally carried out by researchers and designers. We describe the end-to-end process of bringing people together around technology, designing and prototyping ideas, and ultimately testing several devices in their local area. Through this work, we explore different strategies for infrastructuring local residents' participation with technology, including the use of hackathon-like intensive design events and pre-designed kits for assembly. We contribute findings relating to the ability of these strategies to support building communities around civic technology and the challenges that must be addressed.

This paper describes a series of Inventor Days designed to catalyse sustainable relationships between communities and makers to support grassroots innovation. By appropriating core properties of hackathons, the Inventor Days brought together residents in a community and makers from across the city. Over three events, makers and community members worked together to learn about the local area, design novel ideas that addressed local issues and build prototypes. We show evidence that these events created enthusiasm around use of technology to support the community, while developing ongoing relationships that enabled members of the community to continue building on their experiences beyond the events. We propose this as a new means of enabling innovation in communities.
