Digital technologies in agriculture are typically portrayed as enabling more sustainable production while increasing productivity. Yet, commercial solutions rarely address the root causes of unsustainable farming, limiting the uptake of more radical solutions such as agroecology. We conducted fieldwork on 11 UK small-scale agroecological farms investigating their adoption of digital technologies. Far from being anti-technological, agroecological farmers are currently poorly supported by appropriate digital tools. Further, the collaborative nature of agroecological farming, market productivity pressures, and regulatory requirements necessitate complex data practices for coordination, planning, monitoring, and learning. These data practices require labour that is often hidden and causes tension within farms. We develop these insights into a set of guiding principles for designing digital technologies appropriate for agroecology and suggest concrete design opportunities. We present a call to action for HCI to reimagine digital agriculture beyond capitalism and work with existing farmer-led grassroots networks towards technological sovereignty.

We introduce Data Probes, technology-mediated probes designed to reveal some of the inner workings of connected devices, including common embedded sensors and the data they collect. By making these common features both accessible and unfamiliar, the probes supported research participants in looking at these technologies from a different perspective and reflecting on capabilities and behaviours that may be obscured by the design of commercial products. During a study where participants lived and travelled with the probes for a month, we were able to gain generative design insights into people’s attitudes towards and relationships with connected devices, suggesting new opportunities for designs that take alternative approaches to currently entrenched visions of the Internet of Things. We present this exploratory study as an illustration of how a technology-mediated probe might prompt reflection on their technologies and open up new design spaces.

This paper explores the value of a participant-led walking method, during which matters of place in urban or rural contexts are explored. While walking, a diverse dataset is collected, including audio recordings, photographs, GPS tracks, as well as three words that participants are prompted for at each stop along the walk via a bespoke web application. We used this approach in an urban community in the UK and a rural community in Greece as part of ongoing place-based initiatives. Our findings show how participants connected personal and emotional stories with structural issues, countered official, ‘authorised’ discourses about both places, and how maps and videos created after the walks acted as boundary objects. We reflect on the claims of walking as a method that fosters equitable researcher-participant relationships, outline future design directions for participatory walking and mapping technologies, and consider the value of walking methods and map-making for participatory design.

Voice assistants (VAs), typically promoted as omniscient conversational butlers, still remain below users’ expectations. Interaction designers seem to struggle bringing in user perspectives necessary to develop more meaningful VA applications beyond simple use cases such as playing music. One of the reasons might be the immateriality of cloud-based VA technology making it difficult to comprehend such complex and ever-evolving systems. In this paper, we investigate provotyping as a design tool for ‘materialising the immaterial’. In our case study, teams of multidisciplinary experts devised twelve provotypes to explore intangible VA technology. We present and discuss three generalisations in respect to the role of provotypes for the exploration of VAs. Our findings show provotypes can serve as the necessary props by which we can bring in missing perspectives around this technology and generate material which enables designers to speculate, debate, and sketch out ideas for meaningful futures of VA applications.

We gain insight to the COVID-19 pandemic response by the various U.S. states through analysis of open source emergency declaration, mitigation, and response policy data. We propose ASNM + POD, a Partial Ordering Detection extension to the Adaptive Sorted Neighborhood Method to identify redundancies and implied temporal ordering requirements to understand how various U.S. states respond to COVID-19. We further strengthen the well-established ASNM entity matching method and address key limitations of its Longest Common Subsequence extension (ASNM + LCS) through detection of all temporal order requirements. Partial order requirements are determined probabilistically through empirical review of all records’ time-ordered event sequences. We demonstrate effectiveness against a COVID-19 U.S. state policy dataset comprised of daily time-series data pulled from February and October 2022, where attributes are partially and variably populated. ASNM + POD yielded an F1 of 0.995 and an MCC of 0.985, significantly outperforming both ASNM and ASNM + LCS with F1/MCC improvements of 22%/50% and 15%/37%, respectively. Finally, we highlight the limited consensus on policies enacted, the variability in timelines of policy activations/deactivations, and activity at and after the two-year mark.

Prototypes and other ‘things’ have had many uses in HCI research—to help understand a problem, as a stepping stone towards a solution, or as a final outcome of a research process. However, within the messy context of a research through design project, many of these roles do not form part of the final research narratives, restricting the ability of other researchers to learn from this practice. In this paper we revisit prototypes used in three different design research projects, conducted over a period when the Internet of Things emerged into everyday life, exploring complex hidden relationships between the internet, people and physical objects. We aim to explore the unreported roles that prototypes played in these projects, including brokering relationships with participants and deconstructing opaque technologies. We reflect on how these roles align with existing understandings of prototypes in HCI, with particular attention to how these roles can contribute to design around IoT.

As the internet is increasingly embedded in the everyday things in our homes, we notice a need for greater focus on the role care plays in those relationships—and therefore an opportunity to realize unseen potential in reimagining home Internet of Things (IoT). In this paper we report on our inquiry of home dwellers’ relationships to caring for their everyday things and homes (referred to as thingcare). Findings from our design ethnography reveal four thematic qualities of their relationships to thingcare: Care Spectacle, Care Liminality, Ontological Braiding, and Care Condition. Using these themes as touchstones, we co-speculated to produce four speculative IoT concepts to explore what care as a design ethic might look like for IoT and reflect on nascent opportunities and challenges for domestic IoT design. We conclude by considering structures of power and privilege embedded within care practices that critically open new design imaginaries for IoT.

Emerging technologies---such as the voice enabled internet---present many opportunities and challenges for HCI research and society as a whole. Advocating for better, healthier implementations of these technologies will require us to communicate abstract values, such as trust, to an audience that ranges from the general public to technologists and even policymakers. In this paper, we show how a combination of film-making and product design can help to illustrate these abstract values. Working as part of a wider international advocacy campaign, Our Friends Electric focuses on the voice enabled internet, translating abstract notions of Internet Health into comprehensible digital futures for the relationship between our voice and the internet. We conclude with a call for designers of physical things to be more involved with the development of trust, privacy and security in this powerful emerging technological landscape.

We describe the design of SelfReflector an internet-connected mirror that uses online facial recognition to estimate your age and play music from when it thinks you were 14 years old. The mirror was created for a specific shop (SPeX PisTOls optical boutique), within a research through design project centered on the high street as a space of vital social, economic and environmental exchange that offers a myriad of psychosocial support for people beyond a place to purchase goods. We present in detail how the design emerged as our research interests developed related to IoT and how people use the high street to experiment with, and support sense of self. We discuss SelfReflector in relation to challenges for IoT, facial recognition and surveillance technologies, mirrorness and the values of a craft approach to designing technology centering on the nature of the bespoke and 'one-off'.

Social Printers are physical devices that create a pseudonymous social network between households during televised political debates. Through studies conducted around the Scottish Parliamentary Election and EU Referendum in 2016, we aimed to understand how physical devices could be used to engage viewers with televised political debates. By displacing the interaction from conventional social media and second screens we observed that the printers were successful in encouraging the participants to share their thoughts and create a personal social experience. Based on the results we discuss potential implications for conventional social media and second screens in the context of political television programs.

The possibility of linking paper to digital information is enhanced by recent developments in printed electronics. In this article we report the design and evaluation of a local newspaper augmented with capacitive touch regions and an embedded Bluetooth chip working with an adjunct device. These allowed the interactive playback of associated audio and the registration of manual voting actions on the web. Design conventions inherited from paper and the web were explored by showing four different versions of an interactive newspaper to 16 community residents. The diverse responses of residents are described, outlining the potential of the approach for local journalism and recommendations for the design of interactive newsprint.

Our interactions with paper are so habitual as to be subconscious. Paper is an inextricable component of our daily lives. In this paper we present the crafting of, and the reflections on, four prototypes; these prototypes explore how adding new functionality through paper circuits can enrich interactions with paper. We define paper circuits as circuits that have been made through the process of printing or applying conductive ink onto standard paper in order to form electronic or electric circuits. We will provide reflections on not just the benefits of paper circuitry, but also how the newly added affordances gained from paper circuitry effect the experience of paper interactions. This paper will illustrate how this new evolution of paper can be used to produce cheap lightweight ubiquitous electronic products, new art forms, and most importantly enhance the user experience of paper without losing the existing well-loved affordances that paper currently possesses.

This pictorial illustrates some basic and practical notes pertaining to paper circuitry, with a focus on the technicalities of printing, connecting and sensing. The process of creating paper circuit prototypes with little or no specialist equipment will be explored, along with an investigation into printed patterns and grounding options for creating touch and proximity sensors with conductive paint. The methods and techniques this pictorial explores are approached from a craft viewpoint as opposed to the possibly more expected engineering approach.

We describe the process of insight journalism, in which local amateur journalists were used to generate unique insights into the digital needs of a community. We position this as a means for communities to represent themselves to designers, both as a method of designing community technologies and as a first step towards supporting innovation at a local level. To demonstrate insight journalism, we present two case studies of community technologies that were directly inspired, informed and evaluated by journalistic content. Based on this experience, we evaluate the role that insight journalism can play in designing for communities, the particular characteristics that it lends to the design process and how it might be employed to support sustainable community innovation.

Viewpoint is a public voting device developed to allow residents in a disadvantaged community to make their voices heard through a simple, lightweight interaction. This was intended to open a new channel of communication within the community and increase community members' perception of their own efficacy. Local elected officials and community groups were able to post questions on devices located in public spaces, where residents could vote for one of two responses. Question authors were subsequently required to post a response indicating any actions to be taken. Following a two-month trial, we present our experiences and contribute guidelines for the design of public democracy tools and dimensions impacting their effectiveness, including credibility, efficacy and format.

For a long time, the second-hand retail market was the preserve of the charity shop. However, the advent of services like eBay has massively increased its prominence. In this paper we describe a novel Internet of Things-based approach to enhancing the second-hand retail experience by augmenting items with their provenance. After a discussion of the underlying technology, we shall describe its deployment in two related case studies conducted in collaboration with Oxfam charity retail outlets in which we tagged donated items with RFID and QR codes, allowing shoppers to hear the story behind the donated items. Finally, we discuss the impact of the deployments and their implications for the second-hand retail sector.
