Recent work in HCI has explored the use of ICTs for the mobilisation and organisation of values-led communities and social movements. This paper extends this line of work by exploring the design of a communication system for informal, place-based citizen collectives-also referred to as Social Solidarity Movements. The distinctive characteristics of such collectives, namely their decentralised, bottom-up and self-organised organisation, and their lack of monetary resources, pose interesting challenges for communication technology design. The work reported in this paper sought to explore how the values and practices of such collectives can be embodied in mobile communication tools. A system was designed to mirror on-the-ground informal organisational structures, its primary goal being to serve as a probe for research and discussion. Our findings highlight the diversity of channels and organisational structures prevailing in these contexts, their participatory nature, and issues of temporality, anonymity, privacy, and trust, all of which must be considered when designing technologies to support cooperative work. We contribute methodological insights and design implications for mobile technologies underpinning the work of social collectives and their practices.

The recent rise in on-device AI computer vision and dialogue systems has facilitated a growing number of AI fitness related instructional apps. However, these technologies have yet to be explored within the HCI community. To investigate this domain we recruited 12 participants and asked them to engage with five recently launched AI fitness instructor apps. We interviewed participants and thematically analysed transcripts to understand their experience and expectations of these technologies. Our qualitative analysis outlines five main themes focusing on; limitations of computer vision, visual feedback, dialogue with the AI, adapting to the user, and working out with the instructor. Based upon our findings we present five design considerations for designers that relate to three key areas: feedback and motivation, personalising the experience, and building a relationship with the AI. We contribute a first look into people’s initial experiences with on-device AI fitness instructor applications and we provide design considerations to guide future contextually-aware AI research in this domain.

Over half of Syrian refugee households in Lebanon are food insecure with some reliant on an electronic voucher (e-voucher) system for food aid. The interplay between the digitisation of food aid, within the socio-technical context of refugees, and community collaborative practices is yet to be investigated. Through design engagements and interviews with refugees and shop owners we explore the experiences of a Syrian refugee community in Lebanon using the e-voucher system. We provide insights into the socio-technical environment in which the e-voucher system is dispensing aid, the information and power asymmetries experienced, refugee collaborative coping practices and how they interplay with the e-voucher system. We highlight the need for: (1) expanding refugee digital capabilities to encompass understandings of aid technologies and identifying trusted intermediaries and (2) for technologies to support in upholding humanitarian principles and mitigating power and information asymmetries. Lastly, we call for CSCW researchers and humanitarian innovators to consider how humanitarian technologies can enable refugee collaborative practices and adopt everyday security as a lens for designing aid technologies. The paper contributes to CSCW knowledge regarding the interplay between aid technologies and refugees? socio-technical contexts and practices that provides a basis for future technological designs for collaborative technologies for refugee food security.

With the Syrian crisis entering its 8th year, refugees have become the focus of research across multiple disciplines, including design and HCI research. While some researchers have reflected upon designing with refugees, these accounts have been limited to conducting design workshops in formal spaces. Through reflecting on our experiences of conducting design research in informal refugee settlements in Lebanon we unpack lessons learnt, design practices and research approaches that facilitate design engagements with refugees. We highlight the value in participants configuring the design space, using a dialogical approach as well as creating a safe space for both participants and the researcher. We also reflect on the roles that researchers may take on when conducting similar research. By doing so we contribute specific design practices that may be transferrable to other similar contexts.

WhatsApp, as the world's most popular messaging application, offers significant opportunities for improving the reach and effectiveness of engagement projects. In collaboration with the International Federation of Red Cross and Red Crescent Societies (IFRC) we designed WhatFutures, a collaborative future forecasting engagement for global youth using WhatsApp. WhatFutures was successfully deployed with 487 players across 5 countries (Kenya, Bulgaria, Finland, Australia and Hong Kong) to inform strategic change within the IFRC. Based on our analysis of the activity - including 16,100 messages, 95 multimedia artifacts, and a post-engagement survey - we present a reflection upon the design decisions underpinning WhatFutures and identify how decisions made around group structures, processes and externalization of outputs influenced engagement and data quality. We conclude with the wider implications of our findings for the design of engagements that best utilize the affordances of existing messaging applications.

We report on the design of ThinkActive - a system to encourage primary aged school children to reflect on their own personal activity data in the classroom. We deployed the system with a cohort of 30 school children, over a six-week period, in partnership with an English Premier League Football club's health and nutrition programme. The system utilizes inexpensive activity trackers and pseudonymous avatars to promote reflection with personal data using an in-situ display within the classroom. Our design explores pseudonymity as an approach to managing privacy and personal data within a public setting. We report on the motivations, challenges, and opportunities for students, teachers, and third-party providers to engage in the collection and sharing of activity data with primary school children.

This paper analyses sexual health workers' 'talk' around their introduction of a digital platform to enhance a regionally managed condom distribution scheme for young people. In examining the discursive resources workers used in framing the sexual health service, their service users and digital technology, we argue that problematic ideologies around young people and sexuality were exercised and reproduced. Workers positioned themselves as the gatekeepers of young people's sexual health, who were in turn constructed as 'mischievous' and 'misguided', with technology having a corruptive role over what was considered to be 'healthy' and 'normal' sexual relationships. We suggest our findings indicate severe challenges in developing community-commissioned platforms alongside service providers, and questions how plausible user participation can be in attempting to conduct collaborative, participatory and engaged work in this context.

Speculative Enactments are a novel approach to speculative design research with participants. They invite the empirical analysis of participants acting amidst speculative but consequential circumstances. HCI as a broadly pragmatic, experience-centered, and participant-focused field is well placed to innovate methods that invite first-hand interaction and experience with speculative design projects. We discuss three case studies of this approach in practice, based on our own work: Runner Spotters, Metadating and a Quantified Wedding. In distinguishing Speculative Enactments we offer not just practical guidelines, but a set of conceptual resources for researchers and practitioners to critique the different contributions that speculative approaches make to HCI discourse.

In this paper, we present "Care and Connect", a mobile application created through the App Movement platform that aims to identify and rate public places (e.g., parks, shops, cafes) on their 'dementia-friendliness' - their suitability for people with dementia and their carers. Care and Connect saw significant support in its early stages on the online platform, yet failed to engage participants in its design phase and deployment. To unpick this, we contribute an account of its initial use in the community, and then describe findings from research engagements with carers and people with dementia. These workshops used Care and Connect to structure discussions of participants' own experiences of dementia-friendliness, and uncovered themes of 1) trust, 2) exclusion versus inclusion, 3) duration and quality of time, and 4) empathy becoming action. Using this evidence, we advance an account of online community commissioning as a process which needs to understand not only the general issues ongoing in communities facing significant life challenges, but also the particularity of community members' experiences.

The turn to in-the-wild within HCI has given rise to an increasing concern around designing technologies which are available at large scale. Uniquely, at the intersection of public health and HCI, our work has supported the deployment of a mobile application, FeedFinder, over the last three years. We delineate the ground-work that was required to sustain this mobile application over the long-term. Focussing in particular on efforts made to engage institutions in taking ownership over FeedFinder and the data it provides, we reflect on the tensions that arose between users and civic institutions, particularly around "what matters". We provide a reflection on key requirements when designing a health data service and provide three lessons learnt which can guide researchers toward their own successful and productive long-term research deployments.

We introduce Metadating -- a future-focused research and speed-dating event where single participants were invited to "explore the romance of personal data". Participants created "data profiles" about themselves, and used these to "date" other participants. In the rich context of dating, we study how personal data is used conversationally to communicate and illustrate identity. We note the manner in which participants carefully curated their profiles, expressing ambiguity before detail, illustration before accuracy. Our findings proposition a set of data services and features, each concerned with representing and curating data in new ways, beyond a focus on purely rational or analytic relationships with a quantified self. Through this, we build on emerging interest in "lived informatics" and raise questions about the experience and social reality of a "data-driven life".

There is an increasing demand to encourage inclusivity in the design of digital services. In response to this issue we have created App Movement, a platform that enables the promotion, collaborative design, and deployment of community-commissioned mobile applications. The platform facilitates collaborative customization of a common app template, for which the development and deployment of the app is fully automated. We describe the motivation, design and implementation of App Movement, and report the findings from an 8 month deployment wherein 27 campaigns were created, 11 of which have been successful, and over 1,600 users pledged their support using the platform. We present three case studies to demonstrate its use and adoption in successful and unsuccessful campaigns. We discuss the implications of these studies, including questions of governance (ownership of content, liability of user generated content and moderation), sustainability and the potential to extend App Movement beyond location-based review apps.

Breastfeeding is positively encouraged across many countries as a public health endeavour. The World Health Organisation recommends breastfeeding exclusively for the first six months of an infant's life. However, women can struggle to breastfeed, and to persist with breastfeeding, for a number of reasons from technique to social acceptance. This paper reports on four phases of a design and research project, from sensitising user-engagement and user-centred design, to the development and in-the-wild deployment of a mobile phone application called FeedFinder. FeedFinder has been developed with breastfeeding women to support them in finding, reviewing and sharing public breastfeeding places with other breastfeeding women. We discuss how mobile technologies can be designed to support public health endeavours, and suggest that public health technologies are better aimed at communities and societies rather than individual.

The increase of social media and web blogs has enabled a new generation of citizen journalism to provide new perspectives into local communities. However traditional news organisations are currently struggling to incorporate this new form of journalism into their existing organisational workflow. We present an analysis from 10 interviews with professional journalists and explore the current issues faced by professional journalists when searching for reliable and reputable local news sources as well as the perceived role of citizen journalists within a large news organisation. From this analysis we present a set of design implications for building systems that support interaction between citizen and professional journalists in order to encourage participatory news production and diversify national news perspectives.

There is an identified need for objective, reliable, and scalable methods of measuring and recording sleep. Such methods must be designed for easy integration into people's lives in order to support both sleep therapy and everyday personal informatics. This paper describes the design and evaluation of a mobile phone application to record sleep, the design of which has substantive foundation in clinical sleep research. Two user studies were carried out which demonstrate that the application produces valid measurements of sleep quality and high levels of usability, whilst not seriously disturbing sleep or the sleep environment. These findings suggest that the app is suitable for both everyday sleep monitoring in a personal informatics context, and for integration into sleep interventions.

Emerging research has shown that social media services are being used as tools to disclose a range of personal health information. To explore the role of social media in the discussion of mental health issues, and with particular reference to insomnia and sleep disorders, a corpus of 18,901 messages - or Tweets - posted to the microblogging social media service Twitter were analysed using a mixed methods approach. We present a content analysis which revealed that Tweets that contained the word "insomnia" contained significantly more negative health information than a random sample, strongly suggesting that individuals were making disclosures about their sleep disorder. A subsequent thematic analysis then revealed two themes: coping with insomnia, and describing the experience of insomnia. We discuss these themes as well as the implications of our research for those in the interaction design community interested in integrating online social media systems in health interventions.
