Microbes assume an indispensable role in design, given their inherent adaptability, functional diversity, and abundance. Yet, designing with microbes presents notable challenges for biodesigners, stemming from, for example, the distinct temporalities and scales of microbes. Conversely, cultivating microbial sensibilities—reflecting human comprehension and alignment with the distinctive characteristics of microbes—stands out as a unique potential of biodesign for fostering a deep connection between humans and other living entities. In response, we present the concept of “becoming microbes”, a philosophically grounded approach advocating for a non-anthropocentric stance in biodesign, aiming at immersing biodesigners in the realms of microbes with a fresh perspective for imagining the world through the lens of a microbe. By harnessing diverse microbial qualities, including motility and communication, we present various design avenues to explore the notion of becoming microbes. We reflect on the role of merging the biological with the immersive digital systems in this context.@en

Living systems are not only characterised by the sum of individual organisms but also by the multispecies interactions that occur among them, which are crucial for self-regulation, versatility and the evolution of life. Within the fields of biodesign and biological HCI, designers and researchers have strived to facilitate and mimic the qualities that these multispecies interactions entail. However, designing in a way that can account for such intricate dynamic systems presents significant challenges, necessitating alternative approaches that offer greater nuance and sensitivity to natural ecosystems. By incorporating living organisms as interactive components within human-made systems, living artefacts provide an opportunity to explore and design with such sensitivity. Leveraging the inherent interactive potential of living organisms, we propose an ecologically oriented design approach in which living artefacts are recognised and supported within the context of an intricate web of life. To this end, we conducted an in-depth analysis of existing living artefacts, paying particular attention to the multiplicity, connectivity and reciprocity of interactions between humans, other living entities and computers. From this analysis, we identified three distinct types of multispecies interactions that help to articulate and leverage their unique features within, across and beyond living artefacts.@en

Microbes offer designers opportunities to endow artefacts with environmental sensing and adapting abilities, and unique expressions. However, microbe-embedded artefacts present a challenge of temporal dissonance, reflected by a “time lag” typically experienced by humans in noticing the gradual and minute shifts in microbial metabolism. This could compromise fluency of interactions and may hinder timely noticing and attending to microbes in living artefacts. In addressing this challenge, we introduce Cyano-chromic Interface, in which photosynthetic activity of cyanobacteria (Synechocystis sp. PCC6803) is timely surfaced by an electrochromic (EC) material through its monochromatic display. Grounded through interface performance characterization and design primitives, we developed application concepts through which we instantiate how the interface can be tuned for diverse functional and experiential outcomes in living artefacts. We further discuss the potential of aligning human-microbe temporalities for enriched interactions and reciprocal relationships with microbes, and beyond.@en

As knowledge around bio-digital interaction continues to unfold, there are new opportunities for HCI researchers to integrate biology as a design and computational material. Our motivation for the workshop is to bring together interdisciplinary researchers with interest in exploring the next generation of biological HCI and exploring novel bio-digital interfaces implicating diverse contexts, scales, and stakeholders. The workshop aims to provide a space for interactive discussions, presentations, and brainstorming regarding opportunities and approaches for HCI around bio-digital interfaces. We invite researchers from both academia and industry to submit a short position paper in the following areas: Synthetic Biology, Biological Circuits, Do-It-Yourself Biology (DIYBio), Biomimetic Interfaces, Living Interfaces, Living Artefacts, and Bio-ethics. We will evaluate submissions on fit, ability to stimulate discussion, and contribution to HCI. On our website we have included examples of past work in this area to help inspire and inform position papers. Our website will host a recording of the entire workshop session with accepted papers to support asynchronous viewing for participants who are unable to attend in-person or synchronously.

In recent years, there has been a notable proliferation and diversification of works in HCI, that integrate living microorganisms; an imperative lifeform dominating ecosystems of our planet. Yet despite the growing interest, there is a lack of structured lenses with which designers can strategize their processes of surfacing livingness; a material quality inherent in living artefacts with a potential to enrich user experiences and to initiate mutualistic care between humans and microorganisms. Through a systematic artefacts review and a case study on Flavobacteria, we have developed and instantiated a Taxonomy of Surfacing Livingness in Microbial Displays, consisting of six microbe-sensitive, tuneable mechanisms for human noticing of microorganisms: 1) Canvassing, 2) Marking, 3) Magnifying, 4) Translating, 5) Nudging, and 6) Molecular Programming. The taxonomy invites diverse and adaptable ways of generating and crafting microbial displays; towards overcoming microbe-specific surfacing constraints, integrating diverse stakeholders' values, and enabling nuanced address of microbial welfare.@en

Biodesign is an emerging form of design practice integrating biological materials and processes, and there is a growing interest in the field for structured conversations to generate insights on how it can be best taught, researched, and disseminated. In our conversations, we began exploring biodesign under the framework of Living Artefacts, in which livingness is prolonged to the use time of artefacts, and understood as a biological, ecological, and experiential phenomenon. Two researchers investigating Living Artefacts, through their short show-and-tell presentations, initiated threads of moderated open discussions. Using the Living Artefacts framework as a departure point, we collectively explored opportunities and challenges in biodesign, and possible ways in which they could be addressed.@en
