Conference Paper
Full-text available
China's Internet censorship practices are sophisticated and pervasive. Academic research and media reports have examined the Chinese government's varied, expansive methods of censorship and Chinese citizens' techniques of subverting them, but little attention has been paid to understanding how Chi-nese citizens think about censorship in their every...

Social media have become central places where public discourses are generated, sustained, and circulated around public events. So far, much research has examined large-scale dissemination patterns of prominent statements, opinions, and slogans circulated on social media, such as the analysis of keywords and hashtags on Twitter regarding a political...

Recently, diseases like H1N1 influenza, Ebola, and Zika virus have created severe crises, requiring public resources and personal behavior adaptation. Crisis Informatics literature examines interconnections of people, organizations, and IT during crisis events. However, how people use technology to cope with disease crises (outbreaks, epidemics, an...

Game researchers have extensively studied how players form long-term social organizations such as guilds and clans to accomplish complex tasks such as raiding in online games. Few studies have been done to understand how temporary teams (or pickup groups) composed of strangers fulfill complex tasks. Riot Games' League of Legends, a team-based compe...
Conference Paper
Full-text available
Player ranking is a common feature of competitive online games, but little research work has closely examined the ways it mediates player practices within this game genre. In this paper, we present a qualitative study of player practices around ranking in League of Legends (LoL), published by Riot Games and currently one of the most popular eSports...

Full-text available
Recent HCI studies have recognized an analogy between bureaucracy and algorithmic systems; given platformization of content creators, video sharing platforms like YouTube and TikTok practice creator moderation, i.e., an assemblage of algorithms that manage not only creators’ content but also their income, visibility, identities, and more. However,...
Conference Paper
Full-text available
How social media platforms could fairly conduct content moderation is gaining attention from society at large. Researchers from HCI and CSCW have investigated whether certain factors could affect how users perceive moderation decisions as fair or unfair. However, little attention has been paid to unpacking or elaborating on the formation processes...
Conference Paper

Esports, like traditional sports, face governance challenges such as foul play and match fixing. The esports industry has seen various attempts at governance structure but is yet to form a consensus. In this study, we explore esports governance in League of Legends (LoL), a major esports title. Through a two-stage, mixed-methods analysis of rule en...
Conference Paper
Full-text available
To manage user-generated harmful video content, YouTube relies on AI algorithms (e.g., machine learning) in content moderation and follows a retributive justice logic to punish convicted YouTubers through demonetization, a penalty that limits or deprives them of advertisements (ads), reducing their future ad income. Moderation research is burgeonin...
Article
Crisis informatics research has examined geographically bounded crises, such as natural or man-made disasters, identifying the critical role of local and hyper-local information focused on one geographic area in crisis communication. The COVID-19 pandemic represents an understudied kind of crisis that simultaneously hits locales across the globe, e...
Article
Platforms face the challenge of managing toxic behaviors such as flaming, hateful remarks, and harassment. To discipline their users, platforms usually adopt a punitive approach that issues punishments ranging from a warning message to content removal to permanent ban (PB). As the severest punishment, PB deprives the user of their privileges on the...
Conference Paper
Full-text available
Online symptom checkers (OSC) are widely used intelligent systems in health contexts such as primary care, remote healthcare, and epidemic control. OSCs use algorithms such as machine learning to facilitate self-diagnosis and triage based on symptoms input by healthcare consumers. However, intelligent systems' lack of transparency and comprehensibi...
Conference Paper
Online platforms rely upon users or automated tools to flag toxic behaviors, the very first step in online moderation. While much recent research has examined online moderation, the role of flag remains poorly understood. This question becomes even more urgent in automated moderation, where flagging becomes a primary source of human judgment. We co...

Recently, consumer-facing health technologies such as Artificial Intelligence (AI)-based symptom checkers (AISCs) have sprung up in everyday healthcare practice. AISCs solicit symptom information from users and provide medical suggestions and possible diagnoses, a responsibility that people usually entrust with real-person authorities such as physi...
Conference Paper
Full-text available
Toxic behaviors in online gaming such as flaming and harassment have been gaining attention from the research community, yet little consensus has formed about what constitutes toxic behavior. Game developers usually maintain a classification system of toxic behaviors, which oftentimes fails to reflect the dynamic and developing forms of toxicity. I...

Social media is often analyzed as a "front stage" where social media users perform their identities and manage impressions through various forms of user-generated content: text, picture, video, as well as visual expression such as emoticon, emoji, sticker, and meme. Previous scholarship has suggested various functions of visual expression in suppor...

Clinical data, such as laboratory test results, is increasingly being made available to patients through patient portals. However, patients often have difficulties understanding and acting upon the clinical data presented in portals. As such, many turn to online resources to fill their knowledge gaps and obtain actionable advice. In this work, we p...

The contours of user experience (UX) design practice have been shaped by a diverse array of practitioners and disciplines , resulting in a difuse and decentralized body of UX-specifc disciplinary knowledge. The rapidly shifting space that UX knowledge occupies, in conjunction with a long-existing research-practice gap, presents unique challenges an...
Chapter
Citizens are becoming increasingly aware of the prevalence of misinformation, disinformation, and rumors, especially on political topics. But currently, the literature lacks clarity on how citizens are dealing with this issue. And information science and HCI researchers propose design solutions such as diverse information platforms assuming that ci...
Article
As co-design and other participatory design practices increasingly make design outcomes more accessible to everyday citizens, it is also important to understand how designers negotiate the value of design knowledge that undergirds design action and share this knowledge within their own community to facilitate and evolve their practices. In this stu...

Interest in critical scholarship that engages with the complexity of user experience (UX) practice is rapidly expanding, yet the vocabulary for describing and assessing criticality in practice is currently lacking. In this paper, we outline and explore the limits of a specific ethical phenomenon known as "dark patterns," where user value is supplan...
Conference Paper

For decades, HCI scholars have studied technological systems and their relationship to particular contexts and user groups. Increasingly, this scholarship is dependent not only on localized contexts, but also the relationship of local contexts to the global stage, drawing on approaches such as ICT4D and cross-cultural design. In this paper, we exam...
Conference Paper

Streakiness refers to observed tendency towards consecutive appearances of particular patterns. In video games, streakiness is oftentimes inevitable, where a player keeps winning or losing for a short period. However, the phenomenon remains understudied in present online game research. How do players perceive streakiness? How does it impact player...

The occupational landscape of the digital economy is rapidly changing, resulting in the emergence of multidisciplinary occupations. Emerging occupations such as user experience (UX) design are in high demand, but these occupations lack clear boundaries and have yet to develop into a profession with a specified, coherent body of knowledge. While tra...
