Design-oriented research practices create opportunities for constructing knowledge that is more abstracted than particular instances, without aspiring to be at the scope of generalized theories. We propose an intermediate design knowledge form that we namestrong conceptsthat has the following properties: is generative and carries a core design idea, cutting across particular use situations and even application domains; concerned with interactive behavior, not static appearance; is a design element and a part of an artifact and, at the same time, speaks of a use practice and behavior over time; and finally, resides on an abstraction level above particular instances. We present two strong concepts—social navigation and seamfulness—and discuss how they fulfil criteria we might have on knowledge, such as being contestable, defensible, and substantive. Our aim is to foster an academic culture of discursive knowledge construction of intermediate-level knowledge and of how it can be produced and assessed in design-oriented HCI research.

Interaction design that entails a qualitative shift from a symbolic, language-oriented stance to an experiential stance that encompasses the entire design and use cycle. With the rise of ubiquitous technology, data-driven design, and the Internet of Things, our interactions and interfaces with technology are about to change dramatically, incorporating such emerging technologies as shape-changing interfaces, wearables, and movement-tracking apps. A successful interactive tool will allow the user to engage in a smooth, embodied, interaction, creating an intimate correspondence between users' actions and system response. And yet, as Kristina Höök points out, current design methods emphasize symbolic, language-oriented, and predominantly visual interactions. In Designing with the Body, Höök proposes a qualitative shift in interaction design to an experiential, felt, aesthetic stance that encompasses the entire design and use cycle. Höök calls this new approach soma design; it is a process that reincorporates body and movement into a design regime that has long privileged language and logic. Soma design offers an alternative to the aggressive, rapid design processes that dominate commercial interaction design; it allows (and requires) a slow, thoughtful process that takes into account fundamental human values. She argues that this new approach will yield better products and create healthier, more sustainable companies. Höök outlines the theory underlying soma design and describes motivations, methods, and tools. She offers examples of soma design “encounters” and an account of her own design process. She concludes with “A Soma Design Manifesto,” which challenges interaction designers to “restart” their field—to focus on bodies and perception rather than reasoning and intellect.

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.

A set of prominent designers embarked on a research journey to explore aesthetics in movement-based design. Here we unpack one of the design sensitivities unique to our practice: a strong first person perspective—where the movements, somatics and aesthetic sensibilities of the designer, design researcher and user are at the forefront. We present an annotated portfolio of design exemplars and a brief introduction to some of the design methods and theory we use, together substantiating and explaining the first-person perspective. At the same time, we show how this felt dimension, despite its subjective nature, is what provides rigor and structure to our design research. Our aim is to assist researchers in soma-based design and designers wanting to consider the multiple facets when designing for the aesthetics of movement. The applications span a large field of designs, including slow introspective, contemplative interactions, arts, dance, health applications, games, work applications and many others.
