In this pictorial, we introduce a box with four card decks - focusing on settings, metaphors, methods, and caveats - designed to stimulate critical engagement with algorithmic systems from Nordic perspectives. We build upon the scholarship of Dumit [1, p. 604] who suggests that "games are interesting tools because they involve the game player creatively within a dynamic system, requiring them to make decisions under constraints", and, therefore, capturing the systemic and dynamic nature of a socio-technical system, while positioning actors clearly into a particular structure. We apply this perspective to algorithmic systems as complex socio-technical assemblages that commonly entail emergent behaviors and dynamics. This leverages the fact that games excel at capturing dynamic, action-oriented, and inherently conflicted aspects of systems [2].Today, algorithmic systems research often takes the form of critiquing systems-in-use. This leads to a crisis of imagination: rather than envisioning actively what algorithmic systems should be like, it is easy to feel hopeless and powerless amidst the problems of rapidly transforming digital societies. More broadly, dominant narratives and values - like the drive for scalability - dominate our attention. The effects of systems that have been scaled up globally, from search engines to social media and health records, are felt throughout societies. We use the notion of crisis of imagination to refer to the collective struggle to envision and articulate alternatives to seemingly inevitable AI-driven futures. The Nordic Perspectives on Algorithmic Systems card box is a tangible toolkit for responding to this crisis. It was created through workshops across Sweden, Denmark, and Finland, with the aim to destabilize hegemonic algorithmic narratives through situated and playful critique.Reflecting on the observation that discussions about algorithmic systems quickly transform into discussions about society, we offer our card box as an artefact that can facilitate articulating positive and purposeful ideas about desirable societies and algorithmic systems which promote them. After detailed examples about each deck, we document two example games created by university students with inspiration from the card decks. Just Sex reimagines a digital contraception application as a morally uneasy board game where players navigate algorithmic advice amid societal gender biases. YouTube Content Creation Game exposes tensions between creator autonomy and platform opacity. Experiences indicate the cards can help questioning and reframing power dynamics and embedding situated values, while still remaining bounded by folk theories that dominate our understanding of algorithmic technologies.Evidently, the Card Box does not solve' the crisis of imagination - not to even mention the polycrises surrounding us - but it serves to open room for shared reflection. Playful approaches are themselves a radical act at a time of crisis. By adopting Nordicness as a provocative caricature, we sidestep dominant technosolutionist framings to foster dialogues about what systems, values, and institutions we cherish and wish to sustain. The cards are a critical companion, a boundary object that researchers, designers, and other stakeholders can use to facilitate re-imagining algorithmic futures and alternatives.

We 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 primary users of Natural Cycles, focusing specifically on its use as 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.

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.
