Kuddi 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.

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-fdelity 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.
