The vaginal microbiome (often called vaginal flora) plays a crucial role in intimate health, preventing bacterial imbalances and potentially influencing other conditions such as sexually transmitted infections, fertility issues, and even gynecological cancers. This work critically explores present and future technologies that engage with the vaginal microbiome through four speculative provocations. We conceptualize futures with self-tests, smart sensors, domestic microbiology labs, microbiome influencers, microbial donation, and microbial fermented foods — where the vaginal microbes become central to interactive technologies. In doing so, we unpack the more-than-human and critical feminist concerns that arise, challenging us to rethink our relationship with the vagina, as well as with the unseen inhabitants that coexist within it. We discuss the growing intersections of feminist HCI, Bio-HCI, and More-than-Human Design, reflecting on the implications of these proposed futures for our field, hoping to inspire more collaboration and discussion at these intersections.

Reproductive technologies encompass aspects of menstrual health, in/fertility, sexual health, pregnancy, contraception, abortion, or menopause, among many other things, thus entangling aspects of the everyday lives of people of all genders. As reproductive technologies have become-and will continue to be-complicit in enabling or challenging the oppressions enacted on our bodies, it is imperative that we critically reflect on the values and methods used when designing these technologies. Despite a growing body of critical work in HCI, we, a community of feminist scholars working on reproductive technologies, find that there is limited practical guidance on bringing together perspectives such that they can be distributed in easy-to-use, engaging, and collaborative ways. This critical visualization responds to these needs and presents a zine (a collaboratively made booklet) that speculates on reproductive technologies by providing examples from a previous design workshop that happened at NordiCHI 2022 and a guide with activities and reflections on how to organize this kind of workshop. We have also included instructions on how to print and assemble the zine. Some of the examples featured in the zine imagine utopian feminist futures, and some of them intentionally expose or 'trouble' the taken-for-granted dichotomies behind the design and use of reproductive technologies. For instance, several examples draw from the feminist value of embodiment and prioritize the qualitative and felt experiences of menstruating. Other projects highlight the risks of reproductive bodies being commodified and surveilled through technology. The projects are presented through a lens of 'feminist values', which are particularly useful for critically highlighting existing power structures and instead centering subjective experiences that are typically erased in (cis-)normative approaches to reproductive health. We intend the zine to act as a collaborative, accessible, low-tech, and open-ended feminist tool and to use it as a stepping-stone for bringing together an already flourishing community of designers and researchers. Since the zine itself allows for reassembling and reconfiguring, we envision an impromptu zine-assembling activity at the conference presentation, where we invite the audience to add their own feminist values and experiences of designing (and using) reproductive technologies. The zine is free and accessible online, ready to be used in future workshops, offering it as a guide, but also as an easy way to get acquainted with feminist vocabulary in general. We hope this work is one step towards formalizing an (open) community of people working with designing and researching reproductive technologies in the Nordics.

In this work, we introduce biodegradation as a process of more-than-human unmaking. We begin by positioning biodegradation amongst related works in design research before presenting a circular process of making and unmaking biomaterials and living organisms through biodegradation. To exemplify this process, we detail two existing works - ReClaym and Biomenstrual - that exemplify how biodegradability can be explored in design through different biomaterials, methods, and contexts. By diffractively reading these projects through one another, we identify six themes and corresponding suggestions for researchers engaging with biodegradation. Lastly, we discuss the broader design implications and limitations, as well as the more-than-human values that emerge from designing for biodegradation via biomaterials. Through this, we aim to provide design researchers with practical tools and insights for engaging with biodegradation to unmake anthropocentric hierarchies between humans, non-humans, and biomaterials, which in turn can promote environmental sustainability and support more-than-human collaboration and care.

Menstrual pain or dysmenorrhea refers to abdominal cramping or pain before and during menstruation, causing a spectrum of discomfort among people who menstruate. Menstrual pain is often regarded as 'female trouble', as a nuisance that gets dismissed or as a symptom requiring medical intervention. While there are FemTech products that explicitly attend to menstrual pain, they predominantly seek to hide it without accounting for the lived experience of this pain. In this paper we use feminist disability studies (FDS) as a critical analytical lens to reframe the understanding of menstrual pain. Using this lens, we conduct an interaction critique of FemTech market exemplars for alleviating menstrual pain. We then ofer three design provocations to better design menstrual pain technology and call for designers to attend to menstrual pain as a cyclical, chronic lived experience with the potential of spurring leaky contagious coalitions.

Biosensing technologies are on their way to becoming ubiquitous in multimedia interaction. These technologies capture physiological data, such as heart rate, breathing, skin conductance, and brain activity. Researchers are exploring biosensing from perspectives including engineering, design, medicine, mental health, consumer products, and interactive art. These technologies can enhance our interactions, allowing us to connect with our bodies and others around us across diverse application areas. However, the integration of biosignals in HCI presents new challenges pertaining to choosing what data we capture, interpreting these data, its representation, application areas, and ethics. There is a need to synthesize knowledge across diverse perspectives of researchers and designers spanning multiple domains and to map a landscape of the challenges and opportunities of this research area. The goal of this workshop is to exchange knowledge in the research community, introduce novices to this emerging field, and build a future research agenda.

In this studio, we will explore sustainable tangible interfaces by making a range of biomaterials that are bio-based and readily biodegradable. Building off of previous TEI studios that were centered around one specific biomaterial (i.e., bioplastics at TEI'22 and microbial cellulose at TEI'23), this studio will provide participants the ability to experience a wide variety of biomaterials from algae-based bioplastics, to food-waste-based bioclays, to gelatin-based biofoams. We will teach participants how to identify types of biomaterials that are applicable to their own research and how to make them. Through hands-on activities, we will demonstrate how to implement biomaterials in the design of sustainable tangible interfaces and discuss topics sensitized by biological media such as more-than-human temporalities, bioethics, care, and unmaking. Ultimately, our goal is to facilitate a space in which HCI researchers and designers can collaborate, create, and discuss the opportunities and challenges of working with sustainable biomaterials.

This one-day workshop seeks to bring together design researchers that have different orientations and practices for futures and futuring to unpack the role of futuring across design, design artefacts, and designers. Our goal in this workshop is to use examples of established futures to engage with and reflect on questions around the role of futures in HCI/design. We believe that there is a common thread between work from many different researchers, but that the people doing that work are spread across different disciplines and geographical locations. To that end, this workshop will assemble researchers working with different methods and approaches to futures in design and will aim to identify core challenges and opportunities for futures in HCI.

This paper presents the Period Instrument, an interface for musical expression that requires the input of menstrual blood in order to be played. Drawing from both experimental musical instrument design and feminist design, the resulting object exists both as a sound-making device as well as a vector for challenging normative principles of musical instrument design. Moreover, the Period Instrument represents a particular representation and physical embodiment of time. We will discuss the design and technological development of the instrument, focusing primarily on how designing with and for time constraints can result in new interfaces for musical expression.

The ‘intimate horizons’ of algorithmic, self-tracking technologies have become increasingly important. These applications are no longer perceived as distant, instrumental entities, but offer a more affective and intimate experience. In this paper, we address the long-term experience of living with a digital contraception technology that utilizes self-tracking. We draw upon four design workshops with a total of 14 users of the app Natural Cycles to illustrate moments of ambivalent affects and oscillating relations. Based on our analysis, we concretize four dimensions of ambivalence in different scales and temporalities. We propose three strategies of designing with these unavoidable disruptions, conflicting feelings, and shifting relations to acknowledge users’ agentic engagements, nuanced dynamics of intimate self-tracking experiences, and users as embodied and affective beings. We contend that by attending to these existential ambivalences, digital contraceptive can become better configured to plural modes of life and long-term intimate relations that they engender.

Envisioning alternative futures and desirable worlds is a core element of design that must be cultivated, especially when a deep transition of practices, values, and power is necessary for vibrant and just future lifeworlds. In this paper, we contribute towards fabulation as an approach for design futuring that foregrounds feminist commitments and more-than-human concerns. Analyzing two fabulation case studies around biodata and bodily fuids, we ofer three themes based on our process of developing these fabulations: how they engage materials, how they work to trouble temporalities, and how they cultivate imagination. We argue for the emerging potential of fabulation as an approach for open-ended, joyful design futuring, mobilizing speculative storytelling to foreground absent or neglected relations when imagining alternative lifeworlds.
