Soma design research at KTH in Stockholm, Sweden, originated over 10 years ago as an interaction design research approach based on somaesthetic and feminist philosophy. Soma design is a first-person approach to designing full-body interaction with the aim of deepening somaesthetic appreciation. Here, we analyze its development as a design research program, drawing on practical design examples as well as conceptual developments. Key insights for readers interested in soma design research and similar approaches concern: learning and appropriation as individual and meliorative processes; design representations including somatic and sympoietic materials and tools; and the scope of soma design research from a first-person perspective towards the intersubjective and the systemic. A more general contribution, potentially relevant for all readers interested in programmatic design research, is an approach to assessing a program in terms of its generativity, transferability, and scope relative to an aesthetic worldview that the program both enacts and refines through intentional design work, tracing how both program and worldview drift over time.

How can we cultivate deeper attunement to one another, ourselves, and the environment that can, in turn, inform and enrich design? Over the course of four workshops conducted across 1.5 years - primarily outdoors - the authors engaged in prolonged periods of shared silence. This collective silence functioned as an estrangement method, revealing the porous and interdependent boundaries between people and things, mutually constituting one another. We unpack some of the experiential qualities emerging from these experiments and mobilize them for future design processes, including: cultivating multifaceted sensibilities, dynamic modes of noticing and interacting, such as coming together and dispersing, being alone together, and acting or playing in unison; the malleability of silence to specific, orchestrated design activities, such as cooking or designing; and reframing silence, not as an absence, but as a presence - rich with sounds, interactions, and possibilities for engagement. We discuss how to set up temporal and spatial boundaries, alongside boundaries within and between ourselves.

We present a qualitative study with five healthcare experts spe-cialised in different types of touch practice to gain insight in how caring touch can be enacted. Through our analysis we focus onhow 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.

Through 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.

The Pelvic Chair uses soft robotics to gently touch the outer pelvic floor to create awareness of its anatomy and function. Our pelvic floor is an important muscle group that holds up our inner organs. A soma design approach makes out a novel route to know through our senses what an experience in this context feels like, which can provide alternative ways of being in the world. Through annotated imagery, we explore the affordances of soft latex pockets filled with air to convey touch that is appropriate for this intimate, sensitive area. Iteratively, we investigate how layers of materials, area, shape, volume and temporality, together with the specific placement on the body, convey the kinds of experiential qualities we seek. We highlight that somatic design judgements are crucial in guiding this process, going beyond traditional approaches to design that focus on visual assessments, models, or hand-based touch.

Soma 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.

Body maps are visual documents, where somatic experiences can be drawn onto a graphical representation of an outline of the human body. They hold the ability to capture complex and non-explicit emotions and somatic felt sensations, elaborating narratives that cannot be simply spoken. We present an illustrative example of “how-to” complete a body map, together with four case studies that provide examples of using body maps in design research. We identify five uses of body maps as generative tools for soma-based design, ranging from sampling bodily experience, heightening bodily self-awareness, understanding changing bodily experience over time, identifying patterns of bodily experience, and transferring somatic experiential qualities into physical designs. The different requirements for scaffolding the use of body maps in user-centred design versus first-person autobiographical design research are discussed. We provide this Pictorial as a resource for designers and researchers who wish to integrate body maps into their practice.

In this paper, we reflect on the applicability of the concept of trajectories to soma design. Soma design is a first-person design method which considers users’ subjective somatic or bodily experiences of a design. Due to bodily changes over time, soma experiences are inherently temporal. Current instruments for articulating soma experiences lack the power to express the effects of experiences on the body over time. To address this, we turn to trajectories, a well-known concept in the HCI community, as a way of mapping this aspect of soma experience. By showing trajectories through a range of dimensions, we can articulate individual experiences and differences in those experiences. Through analysis of a set of soma experience designs and a set of temporal dimensions within the experiences, this paper demonstrates how trajectories can provide a practical conceptual framing for articulating the temporal complexity of soma designs.

We report on a somaesthetic design workshop and the subsequent analytical work aiming to demystify what is entailed in a non-dualistic design stance on embodied interaction and why a first-person engagement is crucial to its unfoldings. However, as we will uncover through a detailed account of our process, these first-person engagements are deeply entangled with second- and third-person perspectives, sometimes even overlapping. The analysis furthermore reveals some strategies for bridging the body-mind divide by attending to our inner universe and dissolving or traversing dichotomies between inside and outside ; individual and social ; body and technology . By detailing the creative process, we show how soma design becomes a process of designing with and through kinesthetic experience, in turn letting us confront several dualisms that run like fault lines through HCI’s engagement with embodied interaction.

We report on the design processes of two ongoing soma design projects: the Pelvic Chair and the Breathing Wings. These projects take a first-person, soma design approach, grounded in a holistic perspective of the mind and body (the soma). We contribute a reflective account of our soma design processes that deepens the field’s understanding of how soma design is achieved through first-person approaches. We show how we use our somas, our first-person experiences, to stimulate a design process, to prototype through and to use as a way of critiquing emerging designs. Grounding our analysis in new materialism, we show how our designs are in essence, “performative intra-actions”. Using our own somas, our designs open up for experiences within certain constraints, allowing for a material-discursive agency of sorts. Many different somas may be intra-acted through our designs, even if it was our somas who started them.

We devised a Soma Design curriculum with accompanying teaching approaches for a seven-week course at a technical university. In our analysis of students' design concepts and process accounts, we found that they had opened an unusually rich and aesthetically engaging design space. But we also noted how they sometimes struggled with processes such as: "staying in the undecided" long enough to engage deeply with somaesthetic design imaginings; finding, refining and repeatedly returning to an aesthetic quality through the different phases of their design work; liberating them-selves from pre-existing practices or objects in order to find entirely novel design possibilities; shifting from a more rationalistic design process, mainly based on argumenta-tion, into a felt engagement were imaginations are acted out - not talked about; and lacking a technical toolkit for somaesthetically experiencing interactive sociodigital materials. Based on these insights, we provide a set of recommendations for how to teach Soma Design, and we have created an accompanying Soma Design toolkit that will support exploration and design.

Experience Centered Design (ECD) implores us to develop empathic relationships and understanding of participants, to actively work with our senses and emotions within the design process. However, theories of experience-centered design do little to account for emotion work undertaken by design researchers when doing this. As a consequence, how a design researcher's emotions are experienced, navigated and used as part of an ECD process are rarely published. So, while emotion is clearly a tool that we use, we don't share with one another how, why and when it gets used. This has a limiting effect on how we understand design processes, and opportunities for training. Here, we share some of our experiences of working with ECD. We analyse these using Hochschild's framework of emotion work to show how and where this work occurs. We use our analysis to question current ECD practices and provoke debate.

Skin conductance is an interesting measure of arousal level, largely unfamiliar to most end-users. We designed a mobile application mirroring end-users’ skin conductance in evocative visualizations, purposefully made ambiguous to invite rich interpretations. Twenty-three participants used the system for a month. Through the lens of a practice-based analysis of weekly interviews and the logged data, several quite different—sometimes even mutually exclusive—interpretations or proto-practices arose: as stress management; sports performance; emotion tracking; general life logging; personality representation; or behavior change practices. This suggests the value of a purposefully open initial design to allow for the emergence of broader proto-practices to be followed by a second step of tailored design for each identified goal to facilitate the transition from proto-practice to practice. We contribute to the HCI discourse on ambiguity in design, arguing for balancing openness and ambiguity with scaffolding to better support the emergence of practices around biodata.

We articulate and reflect on the use of nature as a sketching material. We have closely documented explorations of various organic and non-organic materials found during excursions in a local forest and how we used them as resources in sketching. This serves as an exemplar case of how sketching in interaction design can be grounded in empirical explorations of nature. We discuss three examples of sketching based on explorations and experiences with elements and objects from a forest. Processes and characteristics of phenomena in nature such falling leaves, melting and freezing of snow, and perennial growth allowed us to expand our design repertoire and sketching skills, especially as new forms of representations and interactions. Based on this we outline three aspects of how nature can be included in sketching processes: being in nature, bringing nature to the lab, and bridging nature and interaction design.

We propose a strong concept we name Somaesthetic Appreciation based on three different enquiries. First, our own autobiographical design enquiry, using Feldenkrais as a resource in our design process, bringing out the Soma Carpet and Breathing Light applications. Second, through bringing in others to experience our systems, engaging with and qualitatively analysing their experiences of our applications. In our third enquiry, we try to pin down what characterises and sets Somaesthetic Appreciation designs apart through comparing with and analysing others' design inquiries as well as grounding them in the somaesthetic theories. We propose that the Somaesthetic Appreciation designs share a subtleness in how they encourage and spur bodily inquiry in their choice of interaction modalities, they require an intimate correspondence -- feedback and interactions that follow the rhythm of the body, they entail a distinct manner of making space shutting out the outside world -- metaphorically and literally -- to allow users to turn their attention inwards, and they rely on articulation of bodily experiences to encourage learning and increased somatic awareness.

In this paper we discuss the design process and results from a design exploration on the use of thermal stimuli in body awareness exercises. A user-study was performed on an interactive prototype in the form of an interactive heat mat. The paper brings forth an alternative understanding of heat as a design material that extends the common understanding of thermal stimuli in HCI as a communication modality to instead bring the aesthetic and experiential properties to the fore. Findings account for felt body experiences of thermal stimuli and a number of design qualities related to heat as a design material are formulated, pointing to experiential qualities concerning the felt body, subjectivity and subtleness as well as material qualities concerning materiality, inertia and heat transfer.

The Ecofriends application was designed to encourage people to reflect on their everyday grocery shopping from social and ecological perspectives. Ecofriends portrays the seasonality of various grocery products as being socially constructed, emphasizing subjective dimensions of what it means for a product to be in season, rather than attempting to communicate it as an established fact. It provides the user with unexpected information (news, weather, blog posts and tweets) about the place where the product was grown, and visualises how the product's popularity shifts throughout the year, among the user's friends, among chefs and other food experts, and the general public. Key findings from users' first encounters with the system are presented. In particular, we discuss aspects of trust, information fragments as catalysts, and how several of the participants were challenged by the system's portrayal of season.

We propose that an interactional perspective on how emotion is constructed, shared and experienced, may be a good basis for designing affective interactional systems that do not infringe on privacy or autonomy, but instead empowers users. An interactional design perspective may make use of design elements such as open-ended, ambiguous, yet familiar, interaction surfaces that users can use as a basis to make sense of their own emotions and their communication with one-another. We describe the interactional view on design for emotional communication, and provide a set of orienting design concepts and methods for design and evaluation that help translate the interactional view into viable applications. From an embodied interaction theory perspective, we argue for a non-dualistic, non-reductionist view on affective interaction design.
