Platforms like Nextdoor and Citizen can increase users’ fear of crime by broadcasting frequent, local, and personalized information about potential safety risks. These platforms can contribute to a dysfunctional fear of crime, which undermines a person’s quality of life and mental health without actually making them feel safer. In this work, we conducted a mixed-methods study to understand the potential for design to foster a functional fear of crime, which motivates precaution without negatively impacting quality of life. We first interview individuals with a dysfunctional fear of crime and then validate interview results with a survey. Through this process, we identified five strategies for designers to support users in developing a more functional fear of crime. These strategies surface overarching theoretical and design implications for designers and researchers of safety platform with the ultimate goal of supporting safety, quality of life, and mental health for users of these platforms.

Given the renewed attention on politics, values, and ethics within our field and the wider cultural milieu, now is the time to take stock of social justice research in HCI. We surveyed 124 papers explicitly pursuing social justice between 2009 and 2022 to better reflect on the current state of justice-oriented work within our discipline. We identified (1) how researchers understood the social justice-relevant harms and benefits, (2) the approaches researchers used to address harm, and (3) the tools that researchers leveraged to pursue justice. Our analysis highlights gaps in social justice work, such as the need for our community to conceptualize benefits, and identifies concrete steps the HCI community can take to pursue just futures. By providing a comprehensive overview of and reflection on HCI’s current social justice landscape, we seek to help our research community strategize, collaborate, and collectively act toward justice.

Adolescents are particularly vulnerable to the pressures created by social media, such as heightened self-consciousness and the need for extensive self-presentation. In this study, we investigate how BeReal, a social media platform designed to counter some of these pressures, influences adolescents' self-presentation behaviors. We interviewed 29 users aged 13-18 to understand their experiences with BeReal. We found that BeReal's design focuses on spontaneous sharing, including randomly timed daily notifications and reciprocal posting, discourages staged posts, encourages careful curation of the audience, and reduces pressure on self-presentation. The space created by BeReal offers benefits such as validating an unfiltered life and reframing social comparison, but its approach to self-presentation is sometimes perceived as limited or unappealing and, at times, even toxic. Drawing on this empirical data, we propose design guidelines for platforms that support authentic self-presentation while fostering reciprocity and expanding beyond spontaneous photo-sharing. These guidelines aim to enable users to portray themselves more comprehensively and accurately, ultimately supporting teens' developmental needs, particularly in building authentic relationships.

Deceptive design patterns (known as dark patterns) are interface characteristics which modify users’ choice architecture to gain users’ attention, data, and money. Deceptive design patterns have yet to be documented in safety technologies despite evidence that designers of safety technologies make decisions that can powerfully influence user behavior. To address this gap, we conduct a case study of the Citizen app, a commercially available technology which notifies users about local safety incidents. We bound our study to Atlanta and triangulate interview data with an analysis of the user interface. Our results indicate that Citizen heightens users’ anxiety about safety while encouraging the use of profit-generating features which offer security. These findings contribute to an emerging conversation about how deceptive design patterns interact with sociocultural factors to produce deceptive infrastructure. We propose the need to expand an existing taxonomy of harm to include emotional load and social injustice and offer recommendations for designers interested in dismantling the deceptive infrastructure of safety technologies.

Early childhood is a critical developmental period when children's experiences have lasting impacts on long-term outcomes. Thus, an evidence-based understanding of how technology can support early childhood education (ECE) classrooms promises to be disproportionately useful to children's long-term wellbeing. We conducted an observational study at ten child-care centers, complemented by interviews with teachers and directors. Using a Uses and Gratifications (U&G) perspective, we found that the gratifications teachers seek when they incorporate technology into the classroom cluster into six categories, such as encouraging technology literacy, regulating children's behavior, and supporting child autonomy. Using these themes, we contribute a set of design priorities for supporting this population. We also contribute an expansion of the U&G perspective to include: 1) gratifications resisted, to account for the ways in which teachers resist gratifying uses of technology, and 2) differentiation between direct gratifications and indirect gratifications to better describe technology use in collaborative contexts.
