Environmental crises demand HCI to shift from human-centered design to more-than-human (MTH) care. Current MTH care often focuses on singular species, overlooking the role of the place in which these care relations are situated. To address this, we turn to mycoremediation—bioremediation of soil and water with fungi. We present findings from a two-week living probe study where participants (N=12) placed and cared for a living mycelium composite in a place of their choosing. Our findings show that engaging with mycoremediation fostered stewardship, extended noticing of multispecies ecologies, and made distant places proximate. Participants’ relationships evolved from expecting feedback from the fungi (a dyadic model) towards attending to their relations with the broader place (a place-based ecological model). We contribute to Bio-HCI and MTH HCI with: 1) an empirical account of mycoremediation as a situated MTH care practice, and 2) design implications for living artifacts that foster affective, ecological connections in place.

Incorporating living microorganisms in artifacts offers opportunities for novel modes of expression and interaction. Bioluminescent algae are unicellular microorganisms that produce light in response to kinetic stimuli and have been a focus of design and HCI research when exploring expressivity of living media. This study advances prior work using bioluminescent algae through designing and engineering a Living Light Interface comprising of bio-kinetic pixels. The resulting interactive system translates digital input into the biological domain by modulating the bioluminescent mechanism and creating different pixel states. The kinetic design of the vibration module uses adjustable weights to induce a wide range of lighting patterns. The hardware design is coupled with organism-centric algorithms, which allow for the generation of dynamic light patterns across the interface. The paper provides a comprehensive visual narrative of a design process that brings these living organisms to the forefront of our technological imagination, blurring the boundaries between biology, algorithmic control, and tangible interfaces.

The speculation of alternative relationships between humans and nonhumans is a crucial element of examining our dominating stance towards nature amidst the ongoing environmental crisis. The notion of designing for interdependence challenges this status quo, focusing on a local ecosystem and embedding carefully crafted artefacts to foster more-than-human relationships. The presented work engages with the intricate interdependence of bees, artefacts, time and location through an ongoing case study of designing with and living with red mason bees (Osmia bicornis). Unpacking the first author's design journey, we elucidate how attentive observations of the garden and engagement in activities such as the making of a beehouse have mobilized caring for the local ecosystem. With our focus on relationships emerging from situating oneself in a location for multispecies cohabitation, our research describes the dynamics of sharing resources between humans and nonhumans and its potential as a repertoire of more-than-human design.

New digital tools offer biodesign with unprecedented opportunities for monitoring, fabricating, iterating, and scaling designs. Serving aligned purposes and beyond, the Digital Twin (DT) is an emerging concept in bioindustries including bioprocessing and agri-food. In these fields, DTs enable comprehensive digital representations of a living system or process with continuous bidirectional connection to the physical world. Despite the concept’s potential to address certain challenges of uncertainty in designing (with) living systems, its applications and implications in biodesign and research remain largely underexplored. To bridge this gap, we propose a conceptual framework that synthesizes existing instantiations of DTs within bioindustries through a dataflow lens. We mobilize the framework through a proof-of-concept DT for biofabrication with mycelium, by unpacking the dataflows within the identified design and operation cycles. We conclude with a discussion on how DT capabilities respond to uncertainties in designing with living systems, limitations, and future work.

This work explores an alternative human-silkworm relationship through crafting a triad of interactive research artifacts that serve as a temporary habitat for domestic silk moths, Bombyx mori. In the first part of the paper, we present the design journey from acquiring the eggs to harvesting movement in orchestrating the improvised ambient music and elaborate on the aspects of materiality and temporality that crafting the habitability involved. In the second part, we reflect on the alternative relationship as intended and embodied during the four months of co-habitation and discuss the ethical and other emergent issues informed by designer-researcher’s autoethnography.

Driving a car can be difficult when it comes to distractions caused by operating the in-vehicle infotainment system (IVIS). In-car passengers often help with performing IVIS-related tasks. However, an IVIS is often not designed with a focus on task collaboration. In this article, we focus on how to design in-car systems with the goal to support collaboration between a driver and a front-seat passenger. Based on infotainment-oriented tasks, we initially explore five key collaborative control concepts by means of an IVIS which differ from each other in terms of the number of available IVIS screens (one or two), access to menus (restricted and unrestricted), and the nature of performing tasks in parallel or one after the other. Results from a simulator study with N = 16 pairs show significant effects of the concepts on social collaboration in terms of perceived social connectedness (measured with sub-dimensions connectedness, affiliation, belongingness, companionship), team performance (coordination effectiveness and team cohesion), and fairness. We found that especially a dedicated passenger IVIS screen empowers front-seat passengers, reduces power dynamics, supports fairness, and minimizes driver distraction (caused by interacting passengers). We discuss the implications of these findings and posit recommendations to design future IVIS in passenger cars with improved driver-passenger collaboration by explicitly designing for balanced power roles, situational awareness, active communication, and a balance between drivers’ privacy and trust toward the passenger. Additionally, we outline a systematic overview of future work to explore the research field of driver-passenger collaboration in more breadth and depth.

With the gradual transition towards assisted and automated driving, the car will transform into a more social environment where passengers and drivers engage in Non-Driving-Related Activities (NDRA). To support collaboration among occupants in future vehicles, research suggests interactive systems controlled by several users at once. In this paper, we explore five concepts for the collaborative performance of NDRA with the use-case of music playlist creation. While prior work investigated the effect on social connectedness, we expand insights towards team performance and fairness. Results from a mixed-subject experiment (N=27) show that the concepts have major consequences on team performance and fairness. Certain concepts can promote or hinder coordination effectiveness and, in turn, impact intra-vehicular collaboration. Our observations also indicate that fairness is key to fostering social collaboration in AVs, while it does not naturally define a high team performance. Subsequently, we provide recommendations to guide future designs of collaborative NDRAs in vehicles.

This paper aims to provide first insights into flash characteristics of bioluminescent microalgae as a potential media for future living light interfaces. A growing number of HCI and interaction design researchers show interest in living material interfaces, which incorporate living organisms for novel responsive behaviour and interaction possibilities in digital and biological hybrids. While much is known about the science of these organisms, their ‘living aesthetics’, i.e., how humans experience the unique temporal changes in a living media, have hardly been explored. To bridge this gap in designing living light interfaces, this paper presents a study of bioluminescent flash characterisation. A DIY shaking device was designed to interact with the liquid living media, providing a range of stimuli including orbital rotation, pulsation and vibration. The living light aesthetics is presented with rich visuals illustrating the intensity variations over time, textural qualities and spatial distribution.

As the material becomes active in disclosing the fullness of its capabilities, the boundaries between human and nonhuman performances are destabilized in productive practices that take their departure from materials. This paper illuminates the embodied crafting of action possibilities in material-driven design (MDD) practices with electroluminescent materials. The paper describes and discusses aspects of the making process of electroluminescent materials in which matter, structure, form, and computation are manipulated to deliberately disrupt the affordance of the material, with the goal to explore unanticipated action possibilities and materialize the performative qualities of the sample. In light of this account, the paper concludes by urging the HCI community to performatively rupture the material, so to be able to act upon it as if it was always unfinished or underdeveloped. This, it is shown, can help open up the design space of smart material composites and reveal their latent affordances.

The emergence of smart materials has urged design education to keep up and take part in introducing them to design students. There has been a great deal of work on teaching conventional materials like wood, metal and polymers in product design. Yet when it comes to learning smart materials, the sources are very limited. Our research group in Delft University of Technology has initiated a number of projects, particularly focusing on understanding technical and experiential characteristics of smart materials as materials of design. Our mission is to communicate smart material qualities through pre-design tinkering activities and functional demonstrators, which also serve as a source for inspiration. In this paper, we explain our approach through an example case on electroluminescent materials.
