When Things Don’t Go As Planned with Digital Contraception.We present a qualitative interview study that examines what happens when things do not go as planned with digital contraception. Through an analysis of 27 interviews with ongoing users of digital contraception at the time of the study, we convey participants’ accounts of their experiences regarding unplanned pregnancies or use of emergency contraception to avoid an unplanned pregnancy. Our analysis considers participants' sense-making processes, and notably how they attended to questions of risk and responsibility. Finally, we depict how these participants came to continue using digital contraception after these experiences. Our study connects to ongoing conversations on technological failures in personal informatics and safety-critical systems. We emphasise that failure and success should not be used as a binary classification of long-term users' relationships with self-tracking technology, which are intimate and critical. Rather, the sustained relation with an intimate technology is composed by several `failures' which are interpreted, acted upon, and, ultimately, overcome.2026CBCristina Bosco et al.Indiana University BloomingtonHealth Self-TrackingBehavior Change & Reflection TechnologyPrivacy & Data Ownership in Self-TrackingCHI
Ecological Systems Theory for Studying and Designing Menstrual TechnologiesMenstrual experiences are shaped by many different stakeholders, entities, and the broader socio-cultural context, or in other words, the ecological systems surrounding a menstruator. We explore what it means to take an ecological approach in studying and designing menstrual technologies. We translated and adapted Ecological Systems Theory (EST) for menstrual wellbeing and packaged the outcome in the form of a socio-ecological Canvas, accompanied by written examples and a set of prompts to facilitate engagement. We invited ten experts to engage with the Canvas in reflective workshops, which informed its further refinement. These sessions highlighted the Canvas' generative value, fostering critical reflection on how design choices are shaped by and ripple across layers of influence. With this translational research, we invite HCI researchers and practitioners to critically reflect on the ecologies they study and design for, envisioning both aspired versions of existing realities and realities that do not exist yet.2026ATAnupriya Tuli et al.KTH Royal Institute of TechnologyReproductive & Women's HealthInclusive DesignTechnology Ethics & Critical HCICHI
Shared Use of Intimate Technology: A Large-Scale Qualitative Study on the Use of Natural Cycles as a Digital ContraceptiveWe present a large-scale, qualitative interview study that examines how an intimate technology within reproductive health comes to be chosen and trusted as a mode of contraception and how its use is shared between partners. We conducted 133 semi-structured interviews with \textit{primary users} of Natural Cycles, focusing specifically on its use as \textit{a digital contraceptive}. Our interpretive analysis, first, sheds light on perceptions of risks and benefits, along with how, and by whom, the decision to adopt Natural Cycles got made. Second, we discuss participants' and their partners' gradual development of trust in the system, and how this intertwines with interpersonal trust. Third, we consider the shared use of Natural Cycles, including partner involvement in temperature tracking, the sharing of intimate data, and navigating specific choices and risks regarding sex and contraception. We make a primarily empirical contribution to Computer Supported Cooperative Work (CSCW) research on shared uses of technology and the sharing of intimate data, and highlight avenues for future work to foster understanding of intimate technologies and their shared use in relational settings.2025ALAiri Lampinen et al.Women & GenderCSCW
Designing for Secondary Users of Intimate TechnologiesDigital contraceptives are intimate technologies that support their users, and their partners, in preventing pregnancy. These technologies rely on basal body temperature data to predict ovulation and calculate a fertile window, where there is a risk of pregnancy if partners have unprotected sex. Although their use is shared and relational, these technologies are mainly designed for a primary user — the person who can become pregnant. We turn our attention to secondary users of digital contraception (i.e., sexual partners), specifically, Natural Cycles. We investigate how secondary users are designed for and how primary users imagine them to be. We contribute empirical insights on how secondary users are and are not involved in digital contraception and conclude with three design proposals describing how digital contraception tools could be designed to involve secondary users. We discuss how designing for secondary users of intimate technologies requires balancing their potential as co-users and adversaries.2025AOAlejandra Gómez Ortega et al.Reproductive & Women's HealthEmpowerment of Marginalized GroupsDIS
Making Intimate Technologies TogetherFeminist research highlights the urgent need to challenge the oppressive design of commercial intimate technologies, particularly how the FemTech industry restricts access to intimate bodily knowledge through paywalls and proprietary systems. Yet, for decades, women and marginalized communities have turned to Do-It-Yourself (DIY) or 'hacking' practices to reclaim control over their own gynecology and intimate health, addressing gaps often ignored by medical research and healthcare. Inspired by visual themes from these movements, this pictorial critically explores how designers and HCI researchers might advance DIY approaches to intimate technologies. We exemplify this with reflections from a series of workshops on handmade intimate sensors, and draw out the joyful potential of collaborative making—building alliances, destigmatizing intimate health, and using craft to subvert gender stereotypes. We discuss matters of safety when making together and contribute to ongoing work on building feminist makerspaces.2025NWNadia Campo Woytuk et al.LGBTQ+ Community Technology DesignParticipatory DesignFood Culture & Food InteractionDIS
Towards Caring Touch From Technologies: Knowledge From Healthcare PractitionersWe present a qualitative study with five healthcare experts specialised in different types of touch practice to gain insight in how caring touch can be enacted. Through our analysis we focus on how to transfer this learning into design considerations towards enacting caring touch from technologies. Despite the rapidly growing expectation for and design interest in touch from technologies intending to enhance care and well-being, the knowledge on how to design caring touch is still fragmented. How caring touch is enacted in inter-personal touch is under-explored and such expertise from healthcare practitioners has not been engaged from the perspective of HCI design research. We propose designers to consider caring as an experiential quality instead of a division between instrumental types of touch and caring types. We recommend when designing for a caring quality in technology-initiated touch that designers create a progression of touch with dynamic sensitivity and adapt the materiality of actuating devices to the plural dimensions of the body's textures.2025CZCaroline Yan Zheng et al.KTH Royal Institute of TechnologyEV Charging & Eco-Driving InterfacesVibrotactile Feedback & Skin StimulationCHI
Designing Touch Technologies for and with Bodies in Menstrual DiscomfortMenstrual discomfort is a prevalent, diverse, and cyclical lived experience, impacting everyday lives. However, in HCI, it has been mostly approached as a data point, leaving much unknown on how technologies can care for these experiences. In response, we designed Touchware, a collection of on-body touch probes with pneumatic shape-change and weight components, which invite wearers to engage with and care for their menstrual discomfort. We report on the participatory soma design process of making Touchware and its two-week-long deployment study with 6 participants in a workplace setting. Our data analysis highlights diffuse and lingering qualities of menstrual discomfort, shedding light on how technologies may touch bodies in vulnerable states. We discuss the importance and challenges of designing touch technologies for and with bodies in the moments of menstrual discomfort. We conclude with a reflection on the agency of touch and its potential to support the self-care labour and nurturing the radical normalization of rest.2025JPJoo Young Park et al.KTH Royal Institute of Technology, Media Technology and Interaction DesignHaptic WearablesShape-Changing Interfaces & Soft Robotic MaterialsCHI
Shape-Kit: A Design Toolkit for Crafting On-Body Expressive HapticsDriven by the vision of everyday haptics, the HCI community is advocating for “design touch first” and investigating “how to touch well.” However, a gap remains between the exploratory nature of haptic design and technical reproducibility. We present Shape-Kit, a hybrid design toolkit embodying our “crafting haptics” metaphor, where hand touch is transduced into dynamic pin-based sensations that can be freely explored across the body. An ad-hoc tracking module captures and digitizes these patterns. Our study with 14 designers and artists demonstrates how Shape-Kit facilitates sensorial exploration for expressive haptic design. We analyze how designers collaboratively ideate, prototype, iterate, and compose touch experiences and show the subtlety and richness of touch that can be achieved through diverse crafting methods with Shape-Kit. Reflecting on the findings, our work contributes key insights into haptic toolkit design and touch design practices centered on the “crafting haptics” metaphor. We discuss in-depth how Shape-Kit’s simplicity, though remaining constrained, enables focused crafting for deeper exploration, while its collaborative nature fosters shared sense-making of touch experiences.2025RZRan Zhou et al.University of Chicago; KTH Royal Institute of TechnologyHaptic WearablesShape-Changing Interfaces & Soft Robotic MaterialsCHI
Becoming One with Kuddi: Touching Data through an Intimate Data PhysicalisationKuddi is a haptic data physicalisation in the form of a soft pillow which combines 12 inflatable pockets to dynamically touch and be touched in relation to the changing menstruating body. This paper presents the soma design process that led to Kuddi's design, as well as Kuddi's evaluation through an auto-ethnographic approach, where the first author lived with Kuddi for two menstrual cycles. The resulting dataset was analysed by the research team using a narrative-led approach. Based on this analysis, we present five thick descriptions that capture how the experience of living with Kuddi led to a changing relation with menstrual pain. We contribute a design case of a haptic data physicalisation intended to touch the body and discuss how the material and interaction design choices embodied in Kuddi led to data visceralisation - a way of feeling data in ways which promote new somatic knowledge and experience.2025GÍGuðrún Margrét Ívansdóttir et al.KTH Royal Institute of Technology , Media Technology and Interaction DesignHaptic WearablesData PhysicalizationFood Culture & Food InteractionCHI
Toward Feminist Ways of Sensing the Menstruating BodyBodily fluids associated with the menstruating body are often disregarded in the design of menstrual-tracking technologies despite their potential to provide valuable knowledge about the menstrual cycle. We prototyped a finger-worn sensor that measures vaginal fluid conductivity, which fluctuates throughout the cycle, and brought it into conversation with people through two speculative workshops (18 people), four fabrication workshops (17 people), and a deployment study where participants brought the sensor into their daily lives (7 people). We unpack that taking a material and sensory approach to intimate tracking nurtures a feminist way of sensing while creating tensions around how we want to know our bodies—tensions around how, where, and when to touch the body, hygiene, data storage, interpretation practices, and labor. With epistemological commitments to feminist materialist and posthuman theory, we invite designers to embrace these tensions.2025NWNadia Campo Woytuk et al.KTH Royal Institute of TechnologyCognitive Impairment & Neurodiversity (Autism, ADHD, Dyslexia)Universal & Inclusive DesignReproductive & Women's HealthCHI
A Route to Somatic Literacy of the Pelvic Floor through Technology-Initiated TouchThe Pelvic Chair is a shape-changing chair that touches the pelvic area. Through rhythmic and gentle movements on different parts of the pelvic area, the touch interactions from the Pelvic Chair invite attention to the anatomy, muscles, and connectedness. We present a user study with 14 participants focusing on their experience of being touched by the Pelvic Chair. Through our qualitative analysis of participants' experiences, we show that meaningful touch can offer an active approach to sensing the pelvic floor that contributes to increasing somatic literacy - becoming familiar with the pelvic floor, being able to feel and distinguish between tension and relaxation, and establishing new connections between the pelvic floor and the body. Using the Pelvic Chair as a design case we show the potential for technology-initiated touch in providing an intimate and safe way of touching and connecting with the body.2025DYDeepika Yadav et al.KTH Royal Institute of TechnologyVibrotactile Feedback & Skin StimulationHaptic WearablesCHI
Exploring the Somatic Possibilities of Shape Changing Car SeatsThrough a soma design process, we explored how to design a shape-changing car seat as a point of interaction between the car and the driver. We developed a low-fidelity prototyping tool to support this design work and describe our experiences of using this tool in a workshop with a car manufacturer. We share the co-designed patterns that we developed: re-engaging in driving; dis-engaging from driving; saying farewell; and being held while turning. Our analysis contributes design knowledge on how we should design for a car seat to `touch' larger, potentially heavier parts of the body including the back, shoulders, hips, and bottom. The non-habitual experience of shape-changing elements in the driver seat helped pinpoint the link between somatic experience and intelligent rational behaviour in driving tasks. Relevant meaning-making processes arose when the two were aligned, improving on the holistic coming together of driver, car, and the road travelled.2024MBMadeline Balaam et al.In-Vehicle Haptic, Audio & Multimodal FeedbackShape-Changing Interfaces & Soft Robotic MaterialsDIS
Critiquing Menstrual Pain Technologies through the Lens of Feminist Disability StudiesMenstrual pain or \textit{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 offer 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.2024JPJoo Young Park et al.KTH Royal Institute of TechnologyReproductive & Women's HealthCHI
Ambivalences in Digital Contraception: Designing for Mixed Feelings and Oscillating RelationsThe ‘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.2023JPJoo Young Park et al.Reproductive & Women's HealthSleep & Stress MonitoringDIS
Tactful Feminist Sensing: Designing for Touching Vaginal FluidsObserving the texture, color, and conductivity of cervical mucus has the potential to support menstrual cycle and fertility tracking, generating a layer of rich bodily, tactile/haptic knowledge in addition to other collected data, such as cycle length or body temperature. This pictorial presents design explorations, four design concepts, and one prototype of a sensor for measuring the conductivity of cervical mucus in vaginal fluids. We present these as instances in the design space for sensing intimate bodily fluids and provide discussions on the proximities, visibilities, and temporalities of these sensing technologies. We offer the unfolding concept of “tactful feminist sensing”, opening up for further engagements with intimate care that attend to the multiplicity and fleshiness of bodies.2023NWNadia Campo Woytuk et al.Reproductive & Women's HealthDiet Tracking & Nutrition ManagementDIS
Feminist Human-Robot Interaction: Disentangling Power, Principles and Practice for Better, More Ethical HRIHuman-Robot Interaction (HRI) is inherently a human-centric field of technology. The role of feminist theories in related fields (e.g. Human-Computer Interaction, Data Science) are taken as a starting point to present a vision for Feminist HRI which can support better, more ethical HRI practice everyday, as well as a more activist research and design stance. We first define feminist design for an HRI audience and use a set of feminist principles from neighboring fields to examine existent HRI literature, showing the progress that has been made already alongside some additional potential ways forward. Following this we identify a set of reflexive questions to be posed throughout the HRI design, research and development pipeline, encouraging a sensitivity to power and to individuals' goals and values. Importantly, we do not look to present a definitive, fixed notion of Feminist HRI, but rather demonstrate the ways in which bringing feminist principles to our field can lead to better, more ethical HRI, and to discuss how we, the HRI community, might do this in practice.2023KWKatie Winkle et al.Human-Robot Collaboration (HRC)Gender & Race Issues in HCITechnology Ethics & Critical HCIHRI
Invisibility or Visibility in Intimate Care at the Workplace? Examining the Use of Breast PumpsAdvances in intimate care technologies and on-body wearables are disrupting how and where we think about and care for our bodies. The boundaries between private and public are increasingly porous. This offers new sites for studying intimate care as technology-use-in-practice. We present a qualitative study on the use of breast pumps in the workplace, based on semi-structured interviews with 19 individuals. Through this, we contribute an illustration of the complexities in carrying out intimate care work at the workplace and what it means to be pumping at the workplace. Our analysis unpacks (in)visibility as a crucial tension in the use of breast pumps in the workplace. We discuss how (in)visibility of personal medical devices plays a mediating role in how individuals exercise bodily rights, and the norms of who fits into professional settings.2023DYDeepika Yadav et al.Stockholm UniversityAging-Friendly Technology DesignAging-in-Place Assistance SystemsCHI
Making New Worlds - Transformative Becomings with Soma DesignSoma design is intended to increase our ability to appreciate through all our senses and lead to more meaningful interactions with the world. We contribute a longer-term study of soma design that shows evidence of this promise. Using storytelling approaches we draw on qualitative data from a three-month study of the soma mat and breathing light in four households. We tell stories of people's becomings in the world as they learn of new possibilities for their somas; and as their somas transform. We show how people drew on their somaesthetic experiences with the prototypes to find their way through troubled times; and how through continued engagement some felt compelled to make transformations in how they live their lives. We discuss the implications for the overarching soma design program, focusing on what is required to design for ways of leading a better life.2022ASAnna Ståhl et al.RISE, Research Institutes of SwedenShape-Changing Interfaces & Soft Robotic MaterialsHuman-Nature Relationships (More-than-Human Design)CHI
Resisting the Medicalisation of Menopause: Reclaiming the Body through DesignThe menopause transition involves bodily-rooted, socially-shaped changes, often in a context of medicalisation that marginalises people based on their age and gender. With the goal of addressing this social justice matter with a participatory design approach, we started to cultivate partnerships with people going through menopause. This paper reports on interviews with 12 women and a design workshop with three. Our data analysis highlights their experiences from a holistic perspective that reclaims the primacy of the body and acknowledges the entanglement of the physical and the psychosocial. Participants' design concepts show how design can come close the body to make space for menopause experiences, recognising and transforming them. We discuss how HCI can actively engage with the body to promote appreciation for it during menopause, and call for design that accompanies people in resisting the medicalisation of menopause as an enactment of social justice in everyday life.2021MFMarianela Ciolfi Felice et al.KTH Royal Institute of TechnologyFoot & Wrist InteractionEmpowerment of Marginalized GroupsCHI
Designing Menstrual Technologies with AdolescentsStarting to menstruate can restrict adolescents' movements due to physiological changes and societal stigma. We present a participatory soma design project advocating for young adolescents to listen to and care for their newly-menstruating bodies, specifically focusing on participation in sport. We designed Menarche Bits, an open-ended prototyping toolkit consisting of shape-changing actuators and heat pads, and used it in two design workshops with seven participants aged 16-18, as part of collaboration and menstrual advocacy in their sports clubs and high school. The participants designed menstrual technologies that respond to menstrual cramps and depressive, anxious feelings before menstruating. We contribute findings on designing menstrual technologies with adolescents using participatory soma design. We found that a toolkit approach to the design of menstrual technologies can allow for pluralist experiences of menstrual cycles. In addition, we found that participatory design with adolescents benefits from drawing on qualities of embodiment and participants' own body literacy.2021MSMarie Louise Juul Søndergaard et al.KTH Royal Institute of TechnologyReproductive & Women's HealthParticipatory DesignCHI
