Mountain areas are especially vulnerable to climate change. In recent years, intermittent droughts have forced many Alpine huts to close early or rely on cable cars or helicopters to import water. To raise awareness of water scarcity among hut visitors, we developed Framing Water, a reflective game based on the data physicalization of each visitor's water consumption during an overnight stay. The game requires players to select their most essential water-using activities without exceeding a fixed limit. Yet it is designed not to provide a univocal answer about the right choices to make but to spark reflection and dialogue around trade-offs in daily practices. We evaluated it with 56 participants and found that water-use decisions are influenced by individual needs, values, and social norms. This work contributes to Sustainable HCI by showing how playful, data-driven artifacts can foster reflection and negotiation of resource use in response to climate challenges.

Designing socio-technical systems for rural areas requires empowering local actors to actively engage in a creative process that thoroughly considers the unique characteristics of these territories. Methods intended for urban contexts often fail to account for rural communities’ specific values, cultures, and needs. Furthermore, the focus is usually on the design of the digital part of the innovation, its requirements, and technological constraints, leaving out other essential enablers. To address this, we present a toolkit designed to boost reflection on the key ‘'ingredients'’ — social, economic, technological, political, and infrastructural — essential for addressing rural challenges through socio-technical interventions. The toolkit offers tangible, user-friendly resources that encourage dialogue, self-reflection, and the creative envisioning of rural transformations. It includes inspirational cardsas well asreflectionquestionsto support communities in evaluating their needs, resources, and aspirations, fosteringself-awareness, learning, andaction.

Mountain huts are buildings in remote mountain areas that depend on local water sources, such as snow, rain, and springs, as they are not connected to centralized water systems. In this pictorial, we report the design process undertaken to explore how data physicalization can communicate the problem of water scarcity in mountain huts with the ultimate goal of encouraging visitors to reduce water usage. The process led to two concepts: one that materializes the impact of each visitor on the water reserve of the hut through a participatory installation, and the other that invites visitors to explore the concept of limit, encouraging reflection on what they are willing to renounce and helping them to make informed choices within tight water constraints. With our work, we aim to contribute to the ongoing efforts in Sustainable HCI to shift the purpose of behavior change from personal gain to the common good.

Technology increasingly offers parents more and more opportunities to monitor children, reshaping the way control and autonomy are negotiated within families. This paper investigates the views of parents and primary school children on mobile technology designed to support child independent mobility in the context of the local walking school buses. Based on a school-year long field study, we report findings on children's and parents' experience with proximity detection devices. The results provide insights into how the parents and children accepted and socially appropriated the technology into the walking school bus activity, shedding light on the way they understand and conceptualize a technology that collects data on children's proximity to the volunteers' smartphone. We discuss parents' needs and concerns toward monitoring technologies and the related challenges in terms of trust-control balance. These insights are elaborated to inform the future design of technology for child independent mobility.

Crowdsourcing for addressing environmental challenges is a promising area in HCI research. This work investigates participation in a crowdsourcing initiative that combined a social-purpose activity with the interest of a company to crowdsource a labour-intensive task. The initiative was based on the deployment of a mobile application for pro-environmental data collection, namely collecting data about weight and type of product packaging. We report the results of a 9-month study conducted within a living lab that involved 96 customers of a large retail store. The analysis of usage logs and patterns of behaviour show different user categories: constant, sprinter and casual users. A survey was conducted to compare those categories as far as demographics, personality traits and usability metrics are concerned. Ten follow-up interviews further investigated motivations behind different usage patterns. The results provide insights on different types of contributors, reporting evidence on what motivated committed and less committed participants.

The wide adoption of mobile devices and social media platforms have dramatically increased the collection and sharing of personal information. More and more frequently, users are called to make decisions concerning the disclosure of their personal information. In this study, we investigate the factors affecting users’ choices toward the disclosure of their personal data, including not only their demographic and self-reported individual characteristics, but also their social interactions and their mobility patterns inferred from months of mobile phone data activity. We report the findings of a field study conducted with a community of 63 subjects provided with (i) a smart-phone and (ii) a Personal Data Store (PDS) enabling them to control the disclosure of their data. We monitor the sharing behavior of our participants through the PDS and evaluate the contribution of different factors affecting their disclosing choices of location and social interaction data. Our analysis shows that social interaction inferred by mobile phones is an important factor revealing willingness to share, regardless of the data type. In addition, we provide further insights on the individual traits relevant to the prediction of sharing behavior.

The domestic environment is more than a place where to live. It is a territory of meaning, a place where pleasure, affect and aesthetics are deeply interwoven with the functional and utilitarian dimensions. With the aging process, the home is progressively invested with new meanings and functions, and becomes the emotional center of older people's life.
