Editor's Note/Chairs' Welcome

Welcome to this issue of the Proceedings of the ACM on Human-Computer Interaction, which will focus on contributions from the research community Computer-Supported Cooperative Work and Social Computing (CSCW). This diverse research community explores how different types of social groups affect, and are affected by, information and communication... (more)

Digital Privacy Challenges with Shared Mobile Phone Use in Bangladesh

Prior research on technology use in the Global South suggests that people in marginalized communities frequently share a single device among multiple... (more)

Motivating Participation in Crowdsourced Policymaking: The Interplay of Epistemic and Interactive Aspects

In this paper, we examine the changes in motivation factors in crowdsourced policymaking. By drawing on longitudinal data from a crowdsourced law... (more)

On Making Data Actionable: How Activists Use Imperfect Data to Foster Social Change for Human Rights Violations in Mexico

In this paper, we examine how activist organizations, focused on human rights violations (HRVs) in Mexico, obtain and translate data to produce actionable insight for social change. Through interviews with 15 participants working in think tanks, human rights centers, non-governmental organizations, and nonprofit organizations, we identified two key... (more)

Multi-Channel Topic-Based Mobile Messaging in Romantic Relationships

With recent shifts from email to messaging apps for personal communication, many communication partners are no longer able to converse using multiple... (more)

It was Fun, but Did it Last?: The Dynamic Interplay between Fun Motives and Contributors' Activity in Peer Production

Peer production communities often struggle to retain contributors beyond initial engagement. This may be a result of contributors' level of motivation, as it is deeply intertwined with activity. Existing studies on participation focus on activity dynamics but overlook the accompanied changes in motivation. To fill this gap, this study examines the... (more)

Collaborative Problem Solving in an Open-Ended Scientific Discovery Game

Countless human pursuits depend upon collaborative problem solving, especially in complex, open-ended domains. As part of the growing technological... (more)

xPress: Rethinking Design for Aging and Accessibility through an IVR Blogging System

Although many older adults are active online, certain age-related disabilities, such as late-life vision impairment, make sustaining online participation difficult. Motivated by the need for accessible online spaces for people experiencing vision impairment in older adulthood, we developed xPress, a voice-based online blogging community. Through a... (more)

Threading is Sticky: How Threaded Conversations Promote Comment System User Retention

The Guardian ---the fifth most widely read online newspaper in the world as of 2014---changed conversations on its commenting platform by altering its design from non-threaded to single-level threaded in 2012. We studied this naturally occurring experiment to investigate the impact of conversation threading on user retention as mediated by several... (more)


Proceedings of the ACM on Human Computer Interaction (HCI) is a journal for research relevant to multiple aspects of the intersection between human factors and computing systems. Characteristics of humans from individual cognition, to group effects, to societal impacts shape and are shaped by computing systems. Human and computer interactions affect multiple aspects of daily life, shape mass social changes, and guide novel computing experiences. These interactions are studied via multiple methods, including ethnography, surveys, experiments, and system implementation among others. PACMHCI covers a broad range of topics and methods that help illuminate the intersection between humans and computing systems. The scope of this journal includes research contributions in new systems for input and output, studies of user experiences with computing systems, scholarship on the individual and group effects of computer mediation, and societal impacts of new human computer interactions. PACMHCI also welcomes contributions on new methodologies, tools, theories and models, as well as visionary and survey papers that help advance the field.
