An in Situ Study to Support Process-based Learning Through Digital Making in Low Socioeconomic Schools
Seeing Each Other at Work
Speculative Artifacts and Exegesis for Algorithmic Visibility
Access to cervical cancer care remains limited in sub-Saharan Africa, where women face compounded socio-cultural, gendered, and structural barriers. This qualitative study explores the lived experiences of nine women diagnosed with cervical cancer in Ethiopia and develops an empirically grounded patient journey map as a design and process artifact based on semi-structured interviews. The journey map reveals fragmented, non-linear care pathways, showing how barriers accumulate from symptom recognition through diagnosis, treatment, and post-treatment support. By visualizing breakdowns and transitions across the care path, the artifact supports problem framing, reflection, and identification of design opportunities. These disruptions intensify emotional and practical burdens, highlighting critical gaps in health literacy, information access, and continuity of care in the healthcare structure. The journey map defines a design-relevant problem space for context-sensitive digital health interventions. This work provides evidence for HCI researchers and practitioners to address accessibility barriers in cervical cancer care in low-resource settings.
Connecting Power and Play
Investigating Interactive Energy Harvesting in Battery-Free Gaming
Battery-free computer gaming offers a vision of sustainable interaction in which games run on hardware that does not require a battery, yet this approach introduces uncertainty due to frequent power failures. Rather than viewing these failures as limitations, this work examines how integrating energy harvesting with application design can encourage users to reimagine and work with such failures, thus shaping behaviour and supporting device use. We present TURNER, a state-of-the-art modular battery-free games console powered by a hand crank and solar cells, created as a research probe to study how energy harvesting mediates the relationship between power and interaction. In a mixed-methods study (N = 60), we explored the influence of energy harvesting on gameplay. Findings show significant variations in harvesting strategies, with interviews surfacing strategies for creating applications that respond to and build on the patterns of system power failure, the ergonomics of energy harvesting, and the value of embedding energy generation into play. Our work offers insights for interactive, sustainable battery-free computers.
How automation impacts worker ecosystems in organizations
A case study of autonomous bus operations at an international airport
Organizations are increasingly immersed in automation programs aimed at enhancing operational efficiency, yet these initiatives fundamentally impact and reshape traditional workplaces. Prior research has examined automation's effects on workers who directly interact with it, but less attention has been given to how broader worker ecosystems are impacted. To address this gap, we investigate an autonomous shuttle bus project at an international airport. We conduct an interview study with nine external experts holding prior experience in similar automation contexts. To engage participants in discussing the impacts of a future autonomous bus operation, we utilize systemic design as a lens and conduct co-design activities with them. Our findings surface key tasks, responsibilities, scenarios, and implementation considerations that affect workers within the broader ecosystem. Through this empirical case, we intend to move beyond techno-centric approaches to automation and illustrate the value of incorporating systemic perspectives in worker-centered automation efforts.
Access to cervical cancer care in sub-Saharan Africa
A narrative review of barriers and opportunities
Background: This narrative review examines the barriers and opportunities that shape access and delivery of cervical cancer care services in sub-Saharan Africa. Unlike prior studies that only focused on single phases of care, this review adopts a comprehensive perspective by assessing access across the full cervical cancer care continuum. Methods: A narrative review was conducted using six databases (Embase, Medline, Web of Science, Scopus, African Index Medicus, and CINAHL Plus). The included studies were thematically analyzed, and emerging themes were interpreted through the lens of the five dimensions of healthcare access: accessibility, availability, affordability, acceptability, and accommodation. Results: Across 38 included studies, findings identified three overarching categories of barriers. (1) Individual-level barriers, including knowledge and awareness, socio-demographic and economic factors, and attitudes and beliefs; (2) Community-level barriers, including cultural acceptance and social norms, and community and social support networks, which further constrained engagement with services; and (3) Health-system-level barriers, including resource limitations, service delivery and quality, and weak policy implementation, which compounded delays and limited care effectiveness. Moreover, opportunities, such as methodological opportunities (community-driven health education, culturally informed healthcare interventions, and multi-stakeholder engagement) and technological opportunities (technology-enhanced health education, digital systems for patient navigation, and task decentralization using mobile health platforms, telehealth, electronic health records, and digital reminder systems), could be effectively integrated into the healthcare system to improve access and service delivery. Conclusion: Access to cervical cancer care in sub-Saharan Africa is shaped by interconnected structural, sociocultural, and individual barriers that extend beyond supply and service availability alone. Literature often focuses on screening, diagnosis, and treatment of cervical cancer, while research gaps identified in this review persist in primary prevention, follow-up, and palliative care services. Findings from the review suggest that integrated, context-specific, and human-centered healthcare interventions are needed to strengthen care coordination, improve access, and enhance care outcomes.
Disability, Differences, and Diversity
Revisiting Inclusive Design and Access
Over 1.3 billion people worldwide live with long-term disabilities, yet many still face systemic exclusion despite advances in accessibility policy and technology. New regulations such as the EU Accessibility Act demand comprehensive transitions, but compliance risks becoming a superficial “checklist” exercise rather than fostering meaningful inclusion. For the HCI community, this moment calls for rethinking our approaches to participation, technology, ethics, and policy. In this meetup, we bring together researchers, practitioners, and advocates to revisit inclusive design through four themes: rethinking inclusive methodologies, disentangling technological challenges, unpacking ethical implications, and navigating policy opportunities. Through interactive mapping activities, participants will share practices, identify collaboration opportunities, and co-develop future directions. Our goal is to build cross-disciplinary connections and create actionable approaches that move beyond compliance toward holistic inclusion, ensuring that accessibility remains central to HCI research and practice.
The Bots of Persuasion
Examining How Conversational Agents' Linguistic Expressions of Personality Affect User Perceptions and Decisions
Large Language Model-powered conversational agents (CAs) are increasingly capable of projecting sophisticated personalities through language, but how these projections affect users is unclear. We thus examine how CA personalities expressed linguistically affect user decisions and perceptions in the context of charitable giving. In a crowdsourced study, 360 participants interacted with one of eight CAs, each projecting a personality composed of three linguistic aspects: attitude (optimistic/pessimistic), authority (authoritative/submissive), and reasoning (emotional/rational). While the CA's composite personality did not affect participants' decisions, it did affect their perceptions and emotional responses. Particularly, participants interacting with pessimistic CAs felt lower emotional state and lower affinity towards the cause, perceived the CA as less trustworthy and less competent, and yet tended to donate more toward the charity. Perceptions of trust, competence, and situational empathy significantly predicted donation decisions. Our findings emphasize the risks CAs pose as instruments of manipulation, subtly influencing user perceptions and decisions.
Persuasion in Pixels and Prose
The Effects of Emotional Language and Visuals in Agent Conversations on Decision-Making
The growing sophistication of Large Language Models allows conversational agents (CAs) to engage users in increasingly personalized and targeted conversations. While users may vary in their receptiveness to CA persuasion, stylistic elements and agent personalities can be adjusted on the fly. Combined with image generation models that create context-specific realistic visuals, CAs have the potential to influence user behavior and decision making. We investigate the effects of linguistic and visual elements used by CAs on user perception and decision making in a charitable donation context with an online experiment (n=344). We find that while CA attitude influenced trust, it did not affect donation behavior. Visual primes played no role in shaping trust, though their absence resulted in higher donations and situational empathy. Perceptions of competence and situational empathy were potential predictors of donation amounts. We discuss the complex interplay of user and CA characteristics and the fine line between benign behavior signaling and manipulation.

Where Do Existing DesignGuidelines Fall Short?
Contestability has been proposed as a key element in designing algorithmic decision-making processes that safeguard decision subjects' rights to dignity and autonomy. However, little is known about how contestability can be operationalized based on decision subjects' needs and preferences. We address this research gap by identifying decision subjects' information and procedural needs for enacting meaningful contestability. To this end, we chose an illegal holiday rental detection scenario as our case; a high-risk decision-making process in the public sector. We conducted 21 semi-structured interviews with citizens with experience renting their homes out and different levels of AI literacy. We found that decision subjects request interventions that facilitate (1) cooperation in sense-making, (2) support in contestation acts, and (3) appropriate responsibility attribution. Our results highlight the cooperative work behind contestability, and motivate future efforts to structure individual and collective action, to personalize explanations for contestability, and to open up sites of contestation in AI pipelines.
