As cities worldwide adopt data-driven approaches to optimize urban forests, computational tools like agent-based models (ABMs) are increasingly popular to simulate forest growth and inform planting decisions. However, ABMs often focus on individual metrics, neglecting forests as interdependent ecosystems. Rooted in anthropocentric ideals, these models risk reducing forests to infrastructures for human benefit, undermining their long-term resilience. This pictorial challenges these limitations by exploring how interface design can transcend reductive, agent-centric representations to foster relational understandings of forest ecosystems as more-than-human bodies. Drawing on feminist theorist Karen Barad's concepts of "diffraction"and "agential cuts,"we craft a repertoire of diffractive interfaces that engage with forest simulation data, revealing how more-than-human bodies can be encountered across diverse temporal, spatial, and agential scales. Through this design exploration, we operationalize more-than- human perspectives in data practices, deepening our understanding of the performative dimensions of interfaces and advancing nuanced, practical approaches to more-than-human design.

This paper innovates in the relationship between sustainable technology suppliers and users, using the example of heat pumps. Heat pumps are necessary for energy transitions in Europe. However, in everyday life in households, heat pumps are often not used as the technology developers intended. This discrepancy presents a challenge for heat pump supply-side actors such as manufacturers and resellers. This paper first presents a design perspective on user improvisation and highlights its value for innovation. We synthesized the perspective in a sensitizing video. We then employed this video to engage with nine supply-side professionals in the Dutch heat pump value network and conducted semi-structured interviews with them to understand their responses to improvisation. We categorized their responses and identified the factors influencing the choice of response. We identify ten different responses and nine motivating factors. We then interpret the responses in the light of our design perspective on user improvisation to highlight areas for socio-technical innovation in the relationship between the heat pump supply and use sides. This innovation can support heat pump uptake and satisfaction and thus improve the quality and rate of renovations.

Domestic heating systems need to change to meet climate targets. We draw on practice theoretical concepts to understand what is needed to integrate heat pumps in Dutch households. From a design orientation, we view households as creative actors integrating technologies into daily life. We report on an ethnographic study of the disruptions and resulting reconfigurations that occur when heat pumps are introduced in Dutch households. Our findings reveal a variety of practice reconfigurations around heat pumps. We also find that these reconfigurations are related to and may influence other practices, including professional practices. We discuss our findings in relation to policy, technology development, and design, and conclude that the required reconfigurations in Dutch household practices could be supported, and that innovative practice reconfigurations emerging from internal household dynamics could contribute to sustainability transitions.

This Conversation at DRS2024 in Boston, attracting around 30 participants, centered on the evolving role of design within multidisciplinary AI teams, particularly in the context of the development of clinical AI applications. As AI is entering healthcare, questions are being raised if and how designers can contribute to AI-driven clinical solutions and whether they need to develop potential other skills and responsibilities. Drawing from ongoing research and insights from various workshops and interviews, the conversation highlighted the importance of the negotiation of agency between humans and machines in clinical settings, translational design for patients, data hierarchy and its impact on design, and finally the importance of language and storytelling in framing interactions mediated by AI.

This is a critique of how designers deal with temporality in design to speculate about socio-technical futures. The paper unpacks how embedded definitions and assumptions of temporality in current design tools contribute to coloniality in designed futures. Based on this critique, we reject the notion that it is only AI that needs fixing, as design practice becomes implicated in how oppression extends from physical systems to global digital platforms. To make these issues visible, we dissect the Futures Cone model used in speculative design. As an alternative, the paper then presents hauntology as a vocabulary that can aid designers in accommodating pluriversal histories in anticipatory futures and reorienting their speculative tools. To illustrate the benefits of the proposed metaphors, the paper highlights examples of coloniality in digital spaces and emphasizes the failure of speculative design to decolonize future imaginaries. Using points of reference from hauntology, ones that engage with states of lingering or spectrality, and notions of nostalgia, absence, and anticipation, the paper contributes to rethinking the role that design tools play in colonizing future imaginaries, especially those pertaining to potentially disruptive technologies.

By 2027 more than 530 M homes will likely adopt at least one type of automated system. This means that a growing number of residents will be living with automated technology in the home, everyday. But living with smart homes is full of conflicts between what residents find appropriate and what technology does instead. Previous research, centering end-user needs, has often focused on smooth living experiences through graphical user interfaces and improved predictions. In this research, we take the more-than-human lens of co-performance to put crises in everyday practices in view, and to conceptualize a new notion of interface. Based on ethnographic data from 11 households, our findings illustrate how crises reveal conflicting ideas of appropriateness, how residents reconfigure their co-performances with technology in response to everyday crises, and how new interfaces are enacted as a result. We conclude by illuminating how researchers and designers should not look at the conflicts and crises emerging in the more-than-human home as something of which to get rid. Instead, they are opportunities for residents and buildings to respond to one another in the context of everyday life and to enact interfaces that were not pre-designed into the building.

Conversation Starters is a series of interactive prototypes that probe how to design explainable interactions with AI in everyday life. Taking a more-than-human approach, we explore how 'failures' could be transformed into opportunities for situated understandings of AI. We describe the process of designing fictional artifacts and scenarios about conversational agents that can grow at home. While overall the project suggests that misunderstandings could help people develop sensitivities for knowing when to trust AI systems, the metaphor of 'growing an AI' (which positions training as a matter of care), highlights that practices of sharing and experimenting could be valuable starting points for designing explainable and trustworthy interactions with of AI.

In this special interest group (SIG) we invite researchers, practitioners, and educators to share their perspectives and experiences on the expansion of human-centred perspective to more-than-human design orientation in human-computer interaction (HCI). This design for and with more-than-human perspectives and values cover a range of fields and topics, and comes with unique design opportunities and challenges. In this SIG, we propose a forum for exchange of concrete experiences and a range of perspectives, and to facilitate reflective discussions and the identification of possible future paths.

The last decade has witnessed the expansion of design space to include the epistemologies and methodologies of more-than-human design (MTHD). Design researchers and practitioners have been increasingly studying, designing for, and designing with nonhumans. This panel will bring together HCI experts who work on MTHD with different nonhumans as their subjects. Panelists will engage the audience through discussion of their shared and diverging visions, perspectives, and experiences, and through suggestions for opportunities and challenges for the future of MTHD. The panel will provoke the audience into reflecting on how the emergence of MTHD signals a paradigm shift in HCI and human-centered design, what benefits this shift might bring and whether MTH should become the mainstream approach, as well as how to involve nonhumans in design and research.

In this one-day workshop we are going to make access. We aim to counteract the phenomenon that access to making (e.g., in makerspaces, fablabs, etc.) is not equally distributed, with certain groups of people being underrepresented (e.g., women∗1). After brief introductions from participants and a set of three impulse keynotes, we will envision and "make"interventions together, such as speculative or provocative objects and actions. The workshop takes a constructive stance with the goal to not rest on empirical and theoretical findings or individual experiences, but to translate those into viable interventions. These serve as exemplars of findings with the clear goal of being deployed soon after.
