This paper explores self-tracking technologies through a more-than-human lens, focusing on the entanglements between protein consumption, urine monitoring, and environmental care. Using autoethnography, I reflect on the practices of measuring protein and nitrogen in urine as a means to interrogate how personal health data intersect with ecological concerns, particularly nitrogen runoff and its contribution to overfertilization of the Baltic Sea. The account highlights tensions between the precision promised by digital health apps and the uncertainty, messiness, and environmental costs of measuring itself. By mapping nitrogen metabolism across bodies, infrastructures, and the environment, the paper identifies potential points of intervention: dietary habits, public discourse, and wastewater treatment. This work positions self-tracking as a ritual of careful noticing that reveals blurred, leaky boundaries between body, infrastructure, and environment.

This track brings together papers that explore more-than-human design practices that generate alternative, plural, situated, and relational approaches to climate futures through affect, aesthetics, and care. Framing climate crisis as a polycrisis of interconnected ecological, political, cultural, and epistemic conditions, the track foregrounds how designers are working across contradictory, incommensurable, and unevenly recognised and experienced impacts of climate change. The included papers examine how more-than-human design can attend to embodied, felt, and sensed worlds of multiple species and digital-material entities, infrastructures, and their environments. Across landscapes, waterscapes, governance, microbial growth, and multiple intelligences, the contributions reveal both the possibilities and frictions of designing as a critical transdisciplinary practice towards more equitable, regenerative, and care-full climate futures under conditions of polycrisis.

There have been repeated calls for more ecological approaches to Sustainable HCI, and for the inclusion of the sociopolitical, structural, historical, and geographical aspects that shape technology-mediated practices of sustainability. Contributing to this discourse, and drawing from scholarship on Law and IT, this paper explores how the law, technology design, market mechanisms, and social norms enable and constrain behaviours — that is, how they regulate them. We use these modalities to discuss two digital technologies: a gig-work platform mediating practices of waste transportation, and an eco-visualisation platform scraping sustainability reports of publicly listed companies. The analysis expands on the set of dynamics that characterise the relations between these practices of sustainability, technology design, and regulation. We conclude by discussing the relevance of this conceptualisation for HCI, specifically in defining the roles of designers as regulators, and regarding design for sustainability as constituted through varying entanglements of these modalities.

This workshop invites participants with diverse backgrounds to imagine stories with tides, to explore response‑ability - a notion used by Donna Haraway to cultivate the capacity to respond with other species. As more HCI communities begin to engage with living entities, we seek to move beyond “responsibility” as a solely human moral property towards relational and reciprocal ways of designing-with them. When the entities we "study" begin to respond to one another, their interactions evolve in ways we cannot fully predict, inviting design practice to stay open and caring for these shifting relations. Using tides as a spatial‑temporal site of inquiry, we will use speculative fabulation to imagine what multispecies response‑ability might look like in place and collectively develop practical guides for examining and incorporating it into design practice.

Micro-phenomenology has recently gained traction in HCI as ways of accessing embodied, lived dimensions of interaction that resist conventional qualitative capture. By foregrounding pre-reflective experience, this approach promises greater experiential precision. However, when designers and HCI researchers attempt to apply Micro-phenomenology in practice, frictions often emerge. The method was not originally designed for design contexts, raising questions about accessibility, adaptability, and epistemic fit. We ask what is gained, transformed, or compromised when micro-phenomenology is brought into design research, and how they might evolve through situated practice. The workshop combines hands-on demonstrations of interviewing and analysis with guided reflective listening, followed by rotating small-group dialogues and material exploration. By bringing together researchers and practitioners interested in embodied and experiential approaches to HCI, the workshop aims to broaden access to micro-phenomenology while spurring critical dialogue about their limitations, transformations, and potential contributions to design research.

In this forum, we explore more-than-human design practices that consider the interactions and interdependencies between humans and nonhuman others, including animals, plants, water, bacteria, sensors, and data. - - Anton Poikolainen Rosén and Sara Heitlinger, Editors.

In recent years, More-Than-Human-Design (MTHD) has gained traction in HCI, as exemplified by a growing body of workshops and publications. As this nascent field progresses, unresolved conceptual and practical methodological challenges continue to surface. It is time for MTHD researchers to critically revisit underlying assumptions, concepts and processes that shape their work. We invite the DIS community to engage with two central themes: first, a critical exploration of anthropocentrism - a core yet complex issue in MTHD; and second, the presentation of practical work that either highlights tensions within MTHD (e.g. how to decenter the human), or proposes ways to navigate these tensions constructively. Through mapping and discussing the challenges, we aim to identify patterns and shared concerns. The workshop will culminate in an open-ended Archive of Tensions, accessible via the workshop website, serving as a collective resource for ongoing reflection and inquiry. Furthermore, the Archive will be presented in an online event and the results will be published as an article.

This one-day workshop explores how encounters with regulatory aspects, before, during and after design, can shape the production of more sustainable futures. Within CSCW and Sustainable HCI, there have been repeated calls to develop more systemic approaches to design that include the political, institutional, and infrastructural aspects underpinning technology-mediated interventions towards sustainability. This workshop targets these calls by drawing attention to the methodological, analytical, and design challenges of considering regulatory and policy-making aspects that can shape both the design and the processes of designing digital technologies. It will be an opportunity to bring together CSCW, Sustainability, Law and other interested scholars, representatives of public institutions, environmental collectives, and diverse actors interested in investigating the "knots" of relations between technology designs, regulatory aspects, and sustainable practices. We plan to accept up to twenty contributions and run the workshop on-site.

When designing with and for complex sustainability processes like waste management, it is crucial to understand digital technologies as entangled with broader systemic factors, including physical infrastructures and regulatory instruments. Within the case of organic household waste management, this pictorial aims at making such relations visible through design methods. We have used yarn to represent the different threads of these entanglements and defined specific configurations: tangles, knots, loose ends, and frayed threads. We discuss how the design practice of giving form to these entanglements can make complex relations between digital technology, infrastructures, and regulatory instruments more visible and actionable for HCI, and explore how digital technologies are – and can be – made to work within them.
