Talk Title: Connecting Realities for Fluid Computer-Mediated Communication
Speaker: Seongkook Heo, Assistant Professor, CS, University of Virginia
Location: HBK 2105 and Zoom
Abstract: Computers are more deeply integrated into our daily lives than ever before, and recent advancements in ML and AI technologies enable computers to comprehend the real world. However, using such capabilities for daily tasks still induces friction because of inefficient interactions with them.
In this talk, I will share my group’s research on how we can better connect the physical and virtual worlds through the design and development of interactive systems. First, I will discuss how we can bring objects and interactions of the physical world into the virtual world to make virtual communication rich and frictionless. In many computer-mediated meetings, we not only share our faces and voices but also physical objects. We developed a remote meeting system that supports the instant conversion of physical objects into virtual objects to allow efficient sharing and manipulation of objects during the conversation.
Second, I will share how we can physicalize computation results into physical actions. Many projects and applications have demonstrated the use of AI in assisting users with visual impairments. However, computers usually only provide guidance feedback to the user and leave the interpretation of the feedback and the execution to the user, which can be cognitively heavy tasks. We suggested automated hand-based spatial guidance to bridge the gap between guidance and execution, allowing visually impaired users to move their hands between two points automatically. Finally, I will discuss the implications and remaining challenges in bridging the two realities.
Bio: Seongkook Heo is an assistant professor in the Department of Computer Science at the University of Virginia. He has been working on Human-Computer Interaction (HCI) research, focusing on bridging the gap between physical and virtual worlds to make computers better support rich and nuanced human interactions by designing novel interactive systems and developing sensing and feedback technologies. His research has been published at top HCI venues, including CHI, UIST, and CSCW, and recognized by Best Paper and Poster Awards at CHI, MobileHCI, and IEEE VR. He is also the recipient of the Engineering Research Innovation Award at the University of Virginia and the Meta Research Award.

Talk Title: Fostering Digital Inclusion: Co-Design with Racial Minority, Low-Income Older Adults for Smart Speaker Applications to Enhance Social Connections and Well-being
Speaker: Dr. Jane Chung, Associate Professor, Virginia Commonwealth University School of Nursing
Location: HBK 2105 and Zoom
Abstract: Older adult residents of low-income housing are at a high risk of unmanaged health conditions, loneliness, and limited healthcare access. Smart speakers have the potential to improve social connections and well-being among older adult residents. We conducted an iterative, user-centered design study with primarily African American older adults who lived alone in low-income housing to develop low-fidelity prototypes of smart speaker applications for wellness and social connections. Focus groups were held to elicit feedback about challenges with maintaining wellness and attitudes towards smart speakers. Through design workshops, they identified several smart speaker functionalities perceived as necessary for improving wellness and social connectedness. Then, several low-fidelity prototypes and use scenarios were developed in the following categories: wellness check-ins, befriending the virtual agent, community involvement, and mood detection. We demonstrate how smart speakers can provide a tool for their wellness and increase access to applications that provide a virtual space for social engagement. This presentation will also highlight strategies for addressing digital health inequities among socially vulnerable older adults. The goal is to enhance technology proficiency, reduce fear, and ultimately foster the acceptance of essential technologies.
Bio: Dr. Jane Chung is an Associate Professor at Virginia Commonwealth University School of Nursing. She is a nurse scientist with special emphasis on aging and technology research. Her research program has two foci: 1) advancing the methods for functional health monitoring and risk detection among older adults using innovative sensor technologies and 2) improving social connectedness and well-being in socially vulnerable older adults based on advances in data science and digital technologies including novel machine learning algorithms. She currently leads two NIH-funded studies – R01 project to identify digital biomarkers of mobility that are predictive of cognitive decline in community-dwelling older adults, and R21 project where her team is developing a smart speaker-based system for automatic loneliness assessment in older adults. Recently, she has been selected as a fellow for the Betty Irene Moore Fellowship for Nurse Leaders and Innovators, and in this fellowship program, she is working on a smart speaker-based intervention designed to assist low-income older adults in managing chronic conditions and daily activities more effectively.

Talk Title: Student Lightning Talks
Location: HBK 2105 and Zoom
This BBL will be dedicated to four student lightning talks. We are excited to hear what they are working on!
How do lightning talks work?
Typically, people give a 4-5 minute “presentation” — this can be very informal or involve slides. The presentation gives some background on your project and then introduces a specific question or “ask” that you want feedback on. Then we have ~15 minutes of conversation with attendees about your question/topic. This is a great opportunity for students to get feedback on research ideas or projects in various stages.

Talk Title: Storytelling Health Informatics: Supporting Collective Efforts Towards Health Equity
Speaker: Dr. Herman Saksono, Assistant Professor, Health Sciences & CS, Northeastern University
Location: HBK 2105 and Zoom
Abstract: We live in a storied life. Stories from people at present and in the past are guiding our actions in the future. Although this narrative mode of knowing complements the pragmatic mode, the pragmatic mode of knowing is the only ubiquitously supported mode in personal health informatics systems. In this talk, I will present my research on personal health informatics that uses storytelling to support health behavior in marginalized communities. These studies examined how storytelling technologies can amplify social connections and knowledge within the family and neighbors. The use of stories socially is a departure from health technologies that are often individually focused. Technologies that portray health solely as an individual’s responsibility could widen health disparities because marginalized communities face numerous health barriers due to systemic inequities. Storytelling health informatics could lessen this burden by supporting health behaviors as collective community efforts.
Bio: Dr. Herman Saksono is an Assistant Professor at Northeastern University with a joint appointment at the Bouvé College of Health Sciences and the Khoury College of Computer Sciences. Previously, he was a postdoctoral research fellow at the Center for Research on Computation and Society at Harvard University.

Talk Title: Navigating the New Normal: An Exploration of Face-to -Face Design Meetings in the Era of Remote Work
Speaker: Karen Holtzblatt
Location: HBK 2105 and Zoom
Abstract: Advancements in technology, the globalization of companies, and a growing awareness of environmental issues have catalyzed a shift in work cultures, transforming traditional face-to-face meetings into online ones. The COVID-19 pandemic further accelerated this transition, establishing videoconferencing as the prevailing mode of professional interaction. But now companies are asking workers to come back to the office at least some of the time. They cite better collaboration, information sharing, and coaching for early career folks. But is that true and what does it really mean? To find out, we 11 conducted deep dive interviews primarily with HCI professionals to understand their experience of working in person vs remotely or hybrid. HCI professionals often find themselves organizing, leading, facilitating, and participating in complex interactive meetings of various kinds: data synthesis, ideation, brainstorming, design review with whiteboarding, roadmapping, and project kickoffs. Our work complements recent research on Return-to-Work that has been conducted by surveys and gives a deeper understanding of what is going on. We sought to gain insights into these types of meetings and interactions to understand participants’ experiences and what works and what doesn’t.
We hope these findings will helpguide both HCI professionals and companies as they choose when to be in-person and how to best run hybrid and remote meetings. We spoke with both senior people and early career professionals. Our insights are also against the backdrop of last year’s research into the experience of remote working during the pandemic and related literature. The presentation will tell stories of our experiences and explicate what drives people to bring people together for these complex meetings and what impacts the success of these meetings in any context. We will also describe the impact of the social dimension of working together. We discuss the need for a shared understanding, ensuring engagement, managing the meeting, and the powerful role of nonverbal communication as well as the need and desire for connection both for its own sake and for the sake of the work and career.

Talk Title: Towards a Science of Human-AI Decision Making: Empirical Understandings, Computational Models, and Intervention Designs
Speaker: Ming Yin, Assistant Professor, Department of Computer Science, Purdue University
Location: HBK 2105 and Zoom
Abstract: Artificial intelligence (AI) technologies have been increasingly integrated into human workflows. For example, the usage of AI-based decision aids in human decision-making processes has resulted in a new paradigm of human-AI decision making—that is, the AI-based decision aid provides a decision recommendation to the human decision makers, while humans make the final decision. The increasing prevalence of human-AI collaborative decision making highlights the need to understand how humans and AI collaborate with each other in these decision-making processes, and how to promote the effectiveness of these collaborations. In this talk, I’ll discuss a few research projects that my group carries out on empirically understanding how humans trust the AI model via human-subject experiments, quantitatively modeling humans’ adoption of AI recommendations, and designing interventions to influence the human-AI collaboration outcomes (e.g., improve human-AI joint decision-making performance).

Talk Title: Mastering the Paper Review Process
Location: HBK 2105 and Zoom
Abstract: Even if you didn’t submit a paper to this year’s CHI conference, if you’re doing research, you probably know something about the review process. For most journals and conferences, submitted papers are read by 2-4 anonymous reviewers, who provide written feedback on the strengths and weaknesses of the paper and decide whether a paper should be accepted, rejected, or revised. But what should go into the review process? And how should you respond to reviews? In this session, we’ll discuss tips and tricks for being an effective reviewer, how to provide constructive criticism, and how to respond to reviewer comments. Bring your questions and experiences with reviewing, and learn more about the ups and downs of academic publishing.

Talk Title: Successful Aging in Digital Era
Speaker: Dr. Madina Khamzina, postdoctoral associate, Department of Family Science, School of Public Health, University of Maryland
Location: HBK 2105 and Zoom
Abstract: This talk discusses the opportunities and challenges of technology to support successful aging. The population of people aged 65 and older is growing faster than any other age group worldwide. While people are living longer, it’s crucial to ask whether those additional years are being lived healthier and happier. Successful aging has become a central priority at both societal and individual health levels. Technology holds the promise to significantly contribute to successful aging in various ways. For example, keeping people physically active, enabling independent living through fall detection and smart home technology, aiding in the early detection and management of diseases, as well as helping maintain social connections to reduce isolation. Keeping in mind that aging in the digital era presents its own set of challenges, we need to ensure that technologies are inclusive and accessible to everyone regardless of age. Addressing the specific needs and older adults’ factors is crucial in the
endeavor to reap the benefits of technology for successful aging.
Bio: Madina earned her Ph.D. degree from the University of Illinois at Urbana-Champaign in December 2022. She is currently a postdoctoral associate at the School of Public Health and is primarily focused on work with the University of Maryland Extension Services.

Talk Title: The Road Less Taken: Pathways to Ethical and Responsible Technologies
Speaker: Dr. Susan Winter, Associate Dean for Research, College of Information Studies, the University of Maryland
Location: HBK 2105 and Zoom
Abstract: Technology is no longer just about technology – now it is about living. So, how do we have ethical technology that creates a better life and a better society? Technology must become truly “human-centered,” not just “human-aware” or “human-adjacent”. Diverse users and advocacy groups must become equal partners in initial co-design and in continual assessment and management of information systems with human, social, physical, and technical components. But we cannot get there without radically transforming how we think about, develop, and use technologies. In this chapter, we explore new models for digital humanism and discuss effective tools and techniques for designing, building, and maintaining sociotechnical systems that are built to be, and remain continuously ethical, responsible, and human-centered.
Bio: Dr. Susan Winter, Associate Dean for Research, College of Information Studies, the University of Maryland. Dr. Winter studies the co-evolution of technology and work practices, and the organization of work.

Talk Title: (Some) things I worry about in HCI/CSCW research
Speaker: Dan Cosley, Program Officer, National Science Foundation
Location: HBK 2105
Abstract: In this talk, rather than report out on some research that I’m involved with, I plan to do some meta-reflection on things that I worry reduce the contribution and impact of research in HCI, CSCW, and related areas. I tentatively plan to focus on four main issues, based both on work I’ve been involved with myself and on other studies I’ve seen:
- Our Methods Make Us Dumb (Other People Know Things)
- Whither the Artifact? (Goldilocks and the Three Stances)
- Things Change (Tweet, Tweet… Musk!); and
- Failure To Generalize (A Grounded Theory of X?)
I haven’t given a talk like this before, and many of the issues have already been observed in some form by people smarter than me, but I think there’s value in bringing them together and hope that talking about this will be useful for both HCI practice and HCI research. I plan to have the talk itself run a little short so we can have a more interactive discussion, so feel free to bring a few of your own worries along to share.
Bio: Dan Cosley is a permanent program officer at NSF as of September 2020, homed in the Human-Centered Computing program in CISE and associated with a number of other solicitations, with a mostly up to date list at https://www.nsf.gov/staff/staff_bio.jsp?lan=dcosley.

Talk Title: Participatory approaches to AI in digital health and well-being
Speaker: Lauren Wilcox, Senior Staff Research Scientist, Google
Location: HBK 2105
Abstract: Advances in computing technology continue to offer us new insights about our health and well-being. As mutually reinforcing trends make the use of wearable and mobile devices routine, we now collect personal, health-related data at an unprecedented scale. Meanwhile, the use of deep-learning-based health screening technologies changes relationships between caregivers and care recipients, with multitudinous implications for equity, privacy, safety, and trust . How can researchers take inclusive and responsible approaches to envisioning solutions, training data, and deploying AI/ML-driven solutions? Who should be involved in decisions about how to use ML/AI in digital health and well-being solutions, and even what solutions matter in the first place? In this talk, I will discuss participatory approaches to designing digital health and well-being technologies with patients, family members, and clinicians. Starting with field studies in clinics exploring how people navigated use of a deployed, diagnostic AI system, and moving onto examples of responsibility AI practices, I will discuss participatory approaches and their importance throughout the technology design, development, and evaluation process.

Talk Title: Designing Health Technology for the Intersection of Evidence and Everyday Life
Speaker: Elena Agapie, Assistant Professor, Informatics, UC-Irvine
Location: HBK 2105
Abstract: Pursuing healthy behaviors is a complex, long-term process that is difficult to maintain. Many technologies promise to support people in pursuing health goals, yet many such technologies fail to account for people’s everyday needs or incorporate evidence-based strategies. In this talk, I discuss the challenges that researchers encounter in designing technologies that use health evidence-driven techniques and accounting for people’s everyday life. I use human-centered design methods and create novel systems that address key challenges that people encounter in working on health goals: starting new behaviors while accounting for the complexities of everyday life and engaging with health goals long term. I discuss how technology can better support clinicians and peers in providing evidence-driven tailored support to clients, for supporting physical activity, and mental health therapy.
Bio: Elena Agapie is an Assistant Professor in the Department of Informatics at the University of California, Irvine.

Talk Title: Unobtrusive Machine-Readable Tags for Identifying, Tracking, and Interacting with Real-World Objects
Speaker: Doğa Doğan, Ph.D. candidate, MIT
Location: HBK 2105
Abstract: Ubiquitous computing requires that mobile and wearable devices are aware of our surroundings so as to augment the real world with contextual information that enriches our interactions with them. For this to work, the objects around us need to carry machine-readable tags, such as barcodes and RFID labels, that describe what they are and communicate this information to devices. While barcodes are inexpensive to produce, they are typically obtrusive, less durable, and less secure than other tags. Regardless of their type, most conventional tags are added to objects post hoc as they are not part of the original design.
I propose to replace this post-hoc augmentation process with tagging approaches that extract objects’ integrated hidden features and use them as machine-detectable tags to make the real world more informative. In this talk, I will introduce three projects: (1) InfraredTags are invisible fiducial markers embedded into 3D printed objects using infrared-transmitting filaments, and detected using cheap infrared cameras. (2) G-ID marks different 3D printed copies of the same object by using unique printing (“slicing”) settings, which result in unobtrusive, machine-detectable surface artifacts. (3) SensiCut is a smart laser cutting platform that leverages speckle imaging and deep learning to distinguish visually similar workshop materials. It adjusts designs based on the chosen material and warns users against hazardous ones. I will show how these methods assist users in creative tasks and enable new interactive applications for augmented reality (AR), object traceability, and user identification.
Bio: DoğaDoğan is a Ph.D. candidate at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and currently an intern at Adobe Research, where he builds novel identification and tagging techniques. At CSAIL, he works with Stefanie Mueller as part of the HCI Engineering Group.

Talk Title: Toward an Equitable Computer Programming Practice Environment for All
Speaker: Carl Haynes-Magyar, Presidential Postdoctoral Fellow, Carnegie Mellon University
Location: HBK 2105
Abstract: Traditional introductory computer programming practice has included writing pseudocode, code-reading and tracing, and code-writing. These problem types are often time-intensive, frustrating, cognitively complex, in opposition to learners’ self-beliefs, disengaging, and demotivating—and not much has changed in the last decade. Pseudocode is a plain language description of the steps in a program. Code-reading and tracing involve using paper and pencil or online tools such as PythonTutor to trace the execution of a program, and code-writing requires learners to write code from scratch. In contrast to these types of programming practice problems, mixed-up code (Parsons) problems require learners to place blocks of code in the correct order and sometimes require the correct indentation and/or selection between a distracter block and a correct code block. Parsons problems can increase the diversity of programmers who complete introductory computer programming courses by improving the efficiency with which they acquire knowledge and the quality of knowledge acquisition itself. This talk will feature experiments designed to investigate the problem-solving efficiency, cognitive load, pattern application and acquisition, and cognitive accessibility of adaptive Parsons problems. The results have implications for how to generate and sequence them.

Carl’s master’s work included evaluating curriculums based on their ability to develop a learner’s proficiencies for assessment and assessing the relationship between perceived and actual learning outcomes during web search interaction. His doctoral work involved studying the design of learning analytics dashboards (LADs) to support learners’ development of self-regulated learning (SRL) skills and investigating how people learn to program using interactive eBooks with adaptive mixed-up code (Parsons) problems. His postdoctoral work is a continued investigation into computing education that involves creating an online programming practice environment called Codespec. The goal is to scaffold the development of programming skills such as code reading and tracing, code writing, pattern comprehension, and pattern application across a gentle slope of different problem types. These types range from block-based programming problems to writing code from scratch. Codespec will support learners, instructors, and researchers by providing help-seeking features, generating multimodal learning analytics, and cultivating IDEAS: inclusion, diversity, equity, accessibility, sexual orientation and gender awareness.

Talk Title: Assistive Smartwatch Application to Support Neurodiverse Adults with Emotion Regulation
Speaker: Vivian Motti, Assistant Professor, Department of Information Sciences and Technology, George Mason University
Location: HBK 2105
Abstract: Emotion regulation is an essential skill for young adults, impacting their prospects for employment, education and interpersonal relationships. For neurodiverse individuals, self-regulating their emotions is challenging. Thus, to provide them support, caregivers often offer individualized assistance. Despite being effective, such an approach is also limited. Wearables have a promising potential to address such limitations, helping individuals on demand, recognizing their affective state, and also suggesting coping strategies in a personalized, consistent and unobtrusive way. In this talk I present the results of a user-centered design project on assistive smartwatches for emotion regulation. We conducted interviews and applied questionnaires to formally characterize emotion regulation. We involved neurodiverse adults as well as parents, caregivers, and assistants as active participants in the project. After eliciting the application requirements, we developed an assistive smartwatch application to assist neurodiverse adults with emotion regulation. The app was implemented, tested and evaluated in field studies. I conclude this talk discussing the role of smartwatches to deliver regulation strategies, their benefits and limitations, as well as the users’ perspectives about the technology.

Talk Title: Ideological Trajectories in Recommendation Systems for News Consumption
Speaker: Cody Buntain, Assistant Professor, iSchool, UMD
Location: HBK 2105
Abstract: While originally developed to increase diversity in product recommendations and show individuals personalized content, recommendation systems have increasingly been criticized for their opacity, potential to radicalize vulnerable users, and incentivizing anti-social content. At the same time, studies have shown that modified recommendation systems can suppress anti-social content across the information ecosystem, and platforms are increasingly relying on such modifications for soft content-moderation interventions. These contradictions are difficult to reconcile as the underlying recommendation systems are often dynamic and commercially sensitive, making academic research on them difficult. This paper sheds light on these issues in the context of political news consumption by building several recommendation systems from first principles, populated with real-world engagement data from Twitter and Reddit. Using domain-level ideology measures, we simulate individuals’ ideological trajectories through recommendations for news sources and examine whether standard recommendation approaches drive individuals to more partisan content and under what circumstances such radicalizing trajectories may emerge. We end with a discussion of personalization’s impact in consuming political content, and implications for instrumenting deployed recommendation systems for anti-social effects.

Talk Title: Aphasia Profiles and Implications for Technology Use
Speaker: Kristin Slawson, Clinical Associate Professor, University of Maryland Hearing and Speech Clinic, and Michael Settles
Location: HBK 2105
Abstract: Conservative estimates suggest that 2.5 million people in the US have aphasia, yet few people have ever heard of the condition. Aphasia is a poorly understood, “invisible disability” that specifically impacts use of language in all forms. People with aphasia are more likely than other stroke survivors to experience social isolation, loss of independence, and significantly lower levels of employment. These immediate consequences have negative ripple effects on the mental and physical health outcomes of survivors and their family members. This talk aims to increase awareness of specific aphasia profiles in hopes of exploring how technology can be adapted to help people with aphasia maintain their prior level of work, social engagement, and independence to the greatest degree possible.
Bio: Kristin Slawson is a Speech-Language Pathologist and a Clinical Associate Professor in Hearing and Speech Sciences. As a brain injury specialist, she is particularly interested in the functional impact of brain injuries on cognitive-linguistic abilities and implications of these changes on maintenance of social connections and return to school and work.

Finding the Grammar of Generative Craft
Abstract: Art and craft design is challenging even with the assistance of computer-aided design tools. Despite the increasing availability and intelligence of software and hardware, artists continue to find gaps between their practices and tools. Through this presentation, I introduce Grammar-driven Craft Design Tools (GCDTs), which explicitly embed and utilized craft domain knowledge as their primary mechanisms and interfaces. Besides bridging the gap between design-aid tools and craft domain knowledge, GCDTs also have additional benefits such as supporting generative design, facilitating learning, and preserving domain knowledge. This talk discusses how the next generation of design-aid tools can help artists find their creative expressions.
Bio: Licia He is a generative artist and a human-computer interaction researcher. After receiving her Ph.D. from the School of Information, University of Michigan, Licia is currently an assistant professor at the Department of Visualization, Texas A&M University, where she leads the Generative Craft Lab.

Everyday stress management technology “in the wild” towards equitable wellbeing computing
Abstract: In this talk, I discuss my work in stress management sensing and intervention technologies for everyday use, i.e. that can be widely adopted by the entire population. I present stress as an example and introduction to equitable wellbeing computing focused on the design, building, and evaluation of affordable, engaging, and efficacious ubiquitous computing technology enabling the equal widespread of wellbeing. I delve in detail into examples of both sensors and interventions that can enable this vision.
First I discuss “sensorless” sensing as an approach to repurposing existing data and infrastructure to obtain continuous, longitudinal stress data that is informed by sound theory on biomechanics. Then I describe an intervention design approach that combines applied machine learning with human-centered design to repurpose engaging attention-grabbing technology (Internet apps, messaging) into personalized just-in-time stress management interventions. My talk finalizes with a future vision on how to take wellbeing computing research out of the lab and “in the wild”, how to manage “shared autonomy” challenges between humans and automated wellbeing systems, and how to focus on embedding ethical principles in the design of these modern systems.

Considering Users’ Basic Psychological Needs in Technology Design
Abstract: Users’ needs should be at the center of new technology design and development efforts. Nonetheless, there is a big gap in current research surrounding basic psychological need fulfillment. According to the Basic Psychological Needs Theory, the satisfaction of our basic psychological needs is necessary for autonomous motivation: if our needs, namely autonomy (desire to have control over our actions), competence (innate desire to experience mastery) and relatedness (desire to care for others and be cared for in return) are fulfilled, we are motivated to engage in a task. If the needs are not fulfilled, our well-being is negatively affected. In the past, basic psychological needs were measured to explain motivation for task engagement in the workplace, education and sport sector but there is little research drawing a link to technology usage and interaction. However, especially with the growing use of technologies in our daily lives, their increasing autonomy and competence in executing tasks, and their role in virtual communication, it is crucial to assess users’ need satisfaction to ensure their well-being when interacting with new technologies. My research focuses on design factors that positively influence users’ basic psychological needs. I will present several studies that address design factors, individual differences in need satisfaction, and the importance of basic psychological needs for technology acceptance.

Understanding Social Media Usage related to Cognitive Disabilities in the Arabic World
Abstract: Social media has become a desirable means for spreading awareness, advocating for rights, establishing communities, acquiring information, and much more. Studies confirmed the substantial value of social support and community belonging for individuals with disabilities and their caregivers. Users in the Arabic world have shown an increasing interest in using social media in the past decade. However, there is limited research that investigated how social media was used in the Arabic world to support people with cognitive disabilities and advocate for their rights. We tried to start filling this gap through a two-stage project. In the first stage, we interviewed caregivers and teachers for children with cognitive disabilities from Saudi Arabia to examine their motivations and concerns around using social media in relation to their children or students’ conditions. We found that caregivers used social media with caution to seek information and emotional support, to spread awareness, and to communicate and build communities. In the second stage of the project, we applied text mining approaches, including sentiment and temporal analyses, on Arabic tweets related to cognitive disabilities during a nine year period. Content volume, temporal evolution, user accounts, sentiment, and topics of the tweets were analyzed. The results provide new insight into public perspectives, which may assist interested entities to form and distribute appropriate resources and information.

Personal Informatics in the Changing, Social World
Abstract: Personal informatics refers to information individuals can collect about themselves, such as food intake, physical activity, sleep, and mood. Current personal informatics tools have been designed primarily for personal use, focusing on quantitative measurements that are easy to collect via sensors or manual input. These systems often overlook the changing nature of everyday life, the social contexts individuals live in, the variety of goals and values they have, and the constraints and preferences associated with these contexts and values. My research has examined the collaborative use of personal informatics data and co-constructed experience in various contexts. In this talk, I will share a few recent studies unpacking ways to rethink personal informatics technology that considers the changing contexts of health behavior, shifting values and priorities, as well as the social roles and relationships that often deeply intertwine with health decisions.

Human-Centered AI: Ensuring Human Control, Enhancing Human Performance
Abstract: A new synthesis is emerging that integrates AI technologies with Human-Computer Interaction to produce Human-Centered AI (HCAI). Advocates of this new synthesis seek to amplify, augment, and enhance human abilities, so as to empower people, build their self-efficacy, support creativity, recognize responsibility, and promote social connections. Researchers, developers, business leaders, policy makers and others are expanding the technology-centered scope of Artificial Intelligence (AI) to include Human-Centered AI (HCAI) ways of thinking. This expansion from an algorithm-focused view to embrace a human-centered perspective, can shape the future of technology so as to better serve human needs. Educators, designers, software engineers, product managers, evaluators, and government agency staffers can build on AI-driven technologies to design products and services that make life better for the users. These human-centered products and services will enable people to better care for each other, build sustainable communities, and restore the environment. The passionate advocates of HCAI are devoted to furthering human values, rights, justice, and dignity, by building reliable, safe, and trustworthy systems. The talk will include examples, references to further work, and discussion time for questions. These ideas are drawn from Ben Shneiderman’s new book Human-Centered AI (Oxford University Press, February 2022). Further information at: https://hcil.umd.edu/human-centered-ai

Building customizable and collaborative AI assistants
Abstract: AI assistance is an increasingly widespread approach to improving knowledge work. However, most commercial AI assistants today offer users limited customization options, making them difficult to integrate in specific workflows. You might be able to change its voice or superficially integrate it with other apps, but what if you wanted to teach it complex new skills (e.g. formulating research questions, connecting ideas, putting together counterarguments, etc.)? In this talk, I will describe two prototypes which explore this question. Dual is an experimental AI assistant whose skills are entirely defined by users through a lightweight scripting language which extends prompt engineering with variables and nested calls. However, even if customizable skills are handy in tailoring an AI assistant’s skill set to the user’s needs, knowing when to use what skill remains challenging. You might only have a broad overarching goal (e.g. learning a concept, solving a problem, making a decision, etc.) whose translation to individual replies is non-trivial. As an early step in addressing this challenge, I will introduce Oneironomicon, a conversational sandbox for training AI assistants on “dreamed-up” user simulators using reinforcement learning before repurposing their know-how to help real users.
Bio: Paul is a Romanian-born Netherlands-based student exploring ways of augmenting human cognition using AI. On the surface, this happens by designing tiny new primitives, mechanics, and affordances which symbiotically bring together minds and machines.

From content moderation to school assignment: What do theories of justice teach us about design?
Abstract: Computational systems have a complex relationship with justice: they may be designed with the intent to promote justice, tasked to resolve injustices, or actively contribute to injustice itself. In this talk I will take two theories of justice, restorative and distributive justice, as frameworks to analyze and imagine alternatives to two real-world systems. First, I will analyze online harms such as harassment and revenge porn and how they are currently addressed through content moderation. I will use restorative justice to discuss the shortcomings of content moderation to effectively address those harms and discuss what alternatives we might design. Second, I will analyze an attempt at using computational systems to promote distributive justice in public schools in San Francisco that ultimately failed to achieve its theoretical promises of transparency, equity, and efficiency. I will show how incorrect modeling assumptions about families’ priorities, constraints, and goals clashed with the real world causing the algorithm to fail. Through this work I argue for recognizing the limitations of algorithmic solutions, broadening how we evaluate computational socio-technical systems, and ongoing engagement with those affected by those systems.
Bio: Niloufar Salehi is an Assistant Professor at the School of Information at UC Berkeley, with an affiliated appointment in Electrical Engineering and Computer Science.

Fake-News Network Model: A Conceptual Framework for Strategic Communication to Deal with Fake News
Abstract: This article analyzes the entire life span of a corporate fake-news report as a case study, proposing a conceptual framework for strategic fake-news communication. Using the confirmation-bias theoretical model, this qualitative textual analysis examines the most widely circulated tweets of a fake-news item about Nike, 603 replies to the tweets, users’ biographical profiles (e.g., political affiliations), the role of opinion leader(s), and relevant prior contexts. The findings provide in-depth insight into how people believe fake news and how their conversations about fake news (re)shape the victim brand’s social realities. Overall, the findings of this study illustrate a “Fake-News Network Model” that explains the underlying mechanisms of how a fake-news item functions together with other aspects (e.g., context, perception, opinion leaders, and cognitive processes), prompting certain people to believe particular fake-news reports and, discuss the victim brand (e.g., Nike) based on that perceived truth. The article discusses the implications of this network model for both fake-news researchers and strategic communication professionals.

AI-powered Interaction: Principles, Models, and Applications
Abstract: How to leverage AI to enhance and augment users’ interaction with computers is a grand challenge. In this talk, I will use text-based communication in Post-PC computing as an example to demonstrate how to integrate AI into interactive systems. We have created multiple AI-powered writing systems that can (1) infer users’ communication intention from noisy input such as eye gaze, voice, and finger touch, and (2) adapt to individuals and support text input on invisible and imaginary keyboards, and (3) detect whether users develop early signs of Parkinson’s Disease. The secret ingredient behind these AI-powered interactive systems is probabilistic modeling: we have created probabilistic models to quantify uncertainty in interaction, and adapted Bayesian inference as a principle of resolving uncertainty in interaction and integrating multimodal input.

Beyond Shape: 3D Printing Kinetic Objects for Interactivity
Abstract: Contemporary AI, driven by Big Data and statistical machine learning, raise important questions for researchers as the promise of machines as collaborative partners in a number of everyday and domain settings Emerging 3D printing technology has enabled the rapid creation of physical shapes. However, 3D-printed objects are typically static with limited or no moving parts. Creating 3D printable objects with kinetic behaviors such as deformation and motion is inherently challenging. To enrich the literature for making movable 3D-printed parts and support a wider spectrum of applications, I introduce the concept of “print driver”, a class of parametric mechanisms that use uniquely designed mechanical elements and are printed in place to augment 3D-printed objects with the ability of deformation, actuation, and sensing. In this talk, I will present a series of my research works to showcase how the print drivers can be used to lower the barrier for making 3D-printed kinetic objects and to support augmented 3D printable behaviors for interactivity. I will also share my personal thoughts on how to utilize print drivers to mediating the physical interface and computation and enabling a wider variety of interactive applications.

Evaluating the Cost of Accessibility through the Lens of Time
Abstract: There have been wild claims of exorbitant costs required to make interfaces accessible, and these claims distract from the reasonable obligation for accessible websites as well as hinder a productive process to enact new rulemaking regarding web accessibility. At the core of the issue is a lack of concrete data regarding the amount of time lost to inaccessible web interfaces. This talk will discuss our findings related to the unanswered question of time loss directly due to inaccessible web interfaces and its implications not only for organizations but most importantly to users with disabilities.

Privacy for Whom? A Multi-Stakeholder Exploration of Privacy Designs
Abstract: How to protect people’s privacy is a key challenge in our increasingly data-driven society. Existing research on privacy protection has primarily focused on end-users of computing systems. However, there are various stakeholders at play in these socio-technical systems. Privacy tools that only consider the end-users might collide with the needs of other stakeholders, making these tools less desirable. Drawing from my work on smart homes, I will present the privacy needs of different stakeholders and how these needs might conflict with each other. For example, my research shows that secondary users (i.e., people, such as guests and passersby, who are neither the owners nor direct users, can be subject to usage and recording of smart home devices) have their own privacy needs, which differ from that of the owners and are often ignored. I will discuss how a multi-stakeholder perspective can influence the design of privacy-enhancing technologies (e.g., cooperative mechanisms that bridge different stakeholders) as well as its implications for other emerging domains (e.g., smart cities).
Bio: Yaxing Yao is an Assistant Professor in the Department of Information Systems at UMBC. His research lies in the intersection of Human-Computer Interaction (HCI), Usable Privacy, and Design. Traditionally, empirical privacy research has focused on the privacy concerns and needs from the individual user’s level. However, evolving networked environments, such as the Internet of Things (IoT) and Smart Homes, are transforming the privacy landscape considering the conflicting privacy needs, imbalanced power dynamics, and social confrontations among different stakeholders beyond a single user. His research shifts the research focus from the privacy experiences of single users to that of multiple stakeholders in these environments, aiming to develop novel privacy-enhancing technologies to address the privacy needs of multiple stakeholders in shared systems such as the IoT, Smart Homes, and Smart Cities. He earned his PhD in Information Science from the School of Information Studies at Syracuse University (2020) and has complete a postdoc position in the CyLab at Carnegie Mellon University (2020-2021).

Connecting Contexts: Designing Privacy and Security Resources to Teach Core Concepts to Children and Families
Abstract: As smartphones, tablets, and related technologies have become commonplace, children are becoming adept at navigating these devices long before they enter school. At the same time, most conversations about how data privacy and security are deferred until children are in middle and high school, if not older. In this talk, I’ll walk through two of my team’s research projects focused on helping children and families develop digital literacy, with a focus on developing their understanding of privacy and security risks and how to protect their data online. I’ll describe ongoing design work with children to develop tools that are both engaging and educational. And I’ll highlight the important role that libraries, educators, and parents play in teaching and reinforcing core privacy and security concepts.

— Facilitating Affect Regulation Using a Vibrotactile Technology
Abstract. Dr. Miri will discuss her work on designing vibrotactile technologies to facilitate affect regulation. Specifically, she will cover how she designed, engineered, and evaluated a vibrotactile breathing pacer to help with stress reduction in a population of young college students. She will discuss whether the pacer was effective in anxiety reduction (both in self report and psychophysiology measures) and, where effective for whom it was effective (e.g., for those low on Big Five Openness, the device was more effective). She will then discuss how she built on the knowledge gained from a college student population, and is currently targeting her research for children diagnosed with autism spectrum disorder.
Bio. Pardis Miri, PhD, is a postdoctoral fellow at Stanford University, where she is working at the intersection of human computer interaction and affective science. Such research is highly interdisciplinary, and involves computer systems, human-computer interaction, psychology, and behavioral science. She is being advised by Professor Keith Marzullo at the University of Maryland iSchool, whose research is on distributed systems, and by Professor James Gross, whose research underlies much of what we now know about emotion regulation. She is also working with Professor Antonio Hardan of the Stanford School of Medicine, whose research is on children with Autism Spectrum Disorder.
Dr. Miri leads a multidisciplinary research team in the Stanford Psychophysiology Lab (the WEHAB team) aimed at the design, engineering, and evaluation of technologies to help people to successfully manage their emotions, moods, and stress responses. She is interested in both neurotypical and neurodiverse populations. Specifically, her work focuses on using theoretically-grounded and data-driven approaches to engineer end-to-end systems that empower people to regulate their unwanted affective experiences and behaviors in their everyday lives. Then, by running carefully-designed clinical experiments, she examines both the average effect (whether the system was effective in changing affect) and the heterogeneous effect (for whom the system was effective). The results of this research will inform practice about what types of interventions are more useful for what type of trait and state individual differences, and will reduce the use of drugs in personalized mental healthcare.

— Automating the News: How Algorithms are Rewriting the Media
Abstract. Amid the push for self-driving cars and the roboticization of industrial economies, automation has proven one of the biggest news stories of our time. Yet the wide-scale automation of the news itself has largely escaped attention. In this rapidly shifting terrain, Nicholas Diakopoulos focuses on the people who tell the stories—increasingly with the help of computer algorithms that are fundamentally changing the creation, dissemination, and reception of the news.
Diakopoulos reveals how machine learning and data mining have transformed investigative journalism. Newsbots converse with social media audiences, distributing stories and receiving feedback. Online media has become a platform for A/B testing of content, helping journalists to better understand what moves audiences. Algorithms can even draft certain kinds of stories. These techniques enable media organizations to take advantage of experiments and economies of scale, enhancing the sustainability of the fourth estate. But they also place pressure on editorial decision-making, because they allow journalists to produce more stories, sometimes better ones, but rarely both.
Bio. Nicholas Diakopoulos is an Associate Professor in Communication Studies and Computer Science (by courtesy) at Northwestern University where he directs the Computational Journalism Lab. He is also a Tow Fellow at Columbia University School of Journalism as well as Associate Professor II at the University of Bergen Department of Information Science and Media Studies. His research focuses on computational journalism, including aspects of automation and algorithms in news production, algorithmic accountability and transparency, and social media in news contexts. He is author of the book, Automating the News: How Algorithms are Rewriting the Media, published by Harvard University Press. Recently he was a resident researcher in the Computational Political Journalism Lab at the Washington Post. He received his Ph.D. and M.S. degrees in Computer Science from the School of Interactive Computing at the Georgia Institute of Technology, and his Sc.B. degree in Computer Engineering from Brown University.

— Information Integration Theory and the Human-Computer Interface
Abstract. Information Integration Theory (IIT) was developed in the 1960’s by Norman H. Anderson. It is a comprehensive theory on how people assess information of different types from different sources to form an overall judgment or decision. It has been used to scale information, determine the integration function, and measure the weighting of factors of information.While I was trained in IIT as a graduate student at the University of Iowa and a post doc at UCSD with Anderson and published numerous studies in the 70’s and 80’s, I failed to truly carry it through to research in HCI and more recently the psychology of video games. In atonement, I present this talk and propose new research methods using the experimental designs of IIT to reap the benefits of IIT in human-computer interaction.
Bio. Kent L. Norman (https://en.wikipedia.org/wiki/Kent_Norman) received his doctorate from the University of Iowa in Experimental Psychology, 1973.

— The Colorectal Cancer Risk Assessment Tool: A Case Study
Abstract. The Colorectal Cancer Risk Assessment Tool redesign project is a good, albeit rare, example of a “soup-to-nuts” project. The project was conducted by the Human Factors Engineering firm I direct, for the National Cancer Institute . It involved literature research, interaction design, and iterative design as well as both qualitative and quantitative evaluations. After describing multiple interactive visualization designs we will discuss evaluation results and show a demonstration of the final implementation. The origin of the project provides some insight into when and how user experience design issues become the focus of a project in the corporate world. Sadly, it also shows when and how user experience design is forgotten in the corporate world.

— Towards Alignable AIs: Helping humans to better understand, steer, and use deep neural networks
Abstract. As the use of machine learning models in product development and data-driven decision-making processes became pervasive in many domains, people’s focus on building a well-performing model has rapidly shifted to understanding how their model works. Recent years have seen an explosion of interest in understanding how Deep Neural Networks (DNNs) work under the hood and more importantly, how we can adjust the way DNNs work based on our knowledge and expectation. However, DNNs’ architecture offers limited transparency, imposing significant challenges in (1) determining when DNNs make unsuccessful predictions with potential bias and more importantly, and (2) improving the model to make the future behavior align with human expectation. In this talk, I will introduce my approach and vision towards establishing an interactive platform that assists data scientists in steering DNNs in a more cost-efficient, effective, and useful way. At the beginning of the talk, I introduce a formative study that aimed at deeply understanding the current practice of data scientists who apply explainable AI tools in designing, building, and deploying machine learning models. Then I introduce my recent approaches focusing on leveraging interactive attention mechanisms towards empowering users to better steering DNNs in the stage of data collection/annotation and model building stages.

— Portable Laser-Cutting: Transitioning From 1000s of Users to Millions of Users
Abstract. Laser-cut 3D models shared online tend to be basic and trivial—models build over long periods of time and by multiple designers are few/nonexistent. I argue that this is caused by a lack of an exchange format that would allow continuing the work. At first glance, it may seem like such a format already exist, as laser cut models are already widely shared in the form of 2D cutting plans. However, such files are susceptible to variations in cutter properties (aka kerf) and do not allow modifying the model in any meaningful way. I consider this format machine specific. I tackled the challenge by writing software tools to modify 2D cutting plans, replacing non-portable elements with portable counterparts. This makes the models portable, but it is still hard to modify them. I thustook a more radical approach, which is to move to a 3D exchange format (kyub). This guarantees portability by generating a new machine-specific 2D-cutting plan for the local machine when exported.And the models inherently allow for parametric modifications. Instead, it raises the question of compatibility: Files already exist in 2D—how to get them into 3D? I demonstrate a software tool to reconstruct the 3D geometry of the model encoded in a 2D cutting plan, allows modifying it using a 3D editor, and re-encodes it to a 2D cutting plan. I demonstrate how this approach allows me to make a much wider range of modifications, including scaling, changing material thickness, and even remixing models. The transition from sharing machine-oriented 2D cutting files, to 3D files, enables users worldwide to collaborate, share, and reuse. And thus, to move on from users creating thousands of trivial models from scratch to collaborating on big complex projects.

— Glitch As Interface
Abstract. When designing interfaces, there is an inherent tension between usability and learnability. Come and consider how style and breakage play into this tension by encouraging and then undermining user trust, and how expert users may take greater ownership over devices by working with breakage to make unique interactions. We will explore the promises of the most common interaction design grammars and contrast them with familiar grammars of other types of screen-based interaction, examining the role played by game feel, and how a play-oriented perspective can decompose a skilled, planned experience into alternate, client-driven use cases. TL:DR; people find their own uses for things, let’s see how that works with screen-based experiences.
Bio. Alex Leitch is a technology consultant and artist whose work focuses on interaction design.

— Who is Behind This? Teaching Students to Evaluate Online Information
Abstract. Young people often turn to the Internet for information, where they face nearly constant questions about what to trust. In this talk, I will argue that educational innovations are a necessary component of efforts to combat the spread of online mis- and disinformation. However, few research-based resources exist to support teachers and students to learn to effectively evaluate online information. I will outline a curricular approach designed to teach strategies that professional fact checkers use to evaluate online sources and explore students’ progress in learning these strategies with findings from a series of intervention studies in high school and college classrooms. I’ll discuss possibilities and hurdles for teaching evaluation strategies and consider how technological solutions might accompany educational innovations.
Bio. Sarah McGrew is an Assistant Professor in the College of Education at the University of Maryland, College Park. Her research focuses on young people’s civic online reasoning—how they search for and evaluate online information on contentious social and political topics—and how schools can better support students to learn effective evaluation strategies. Dr. McGrew has developed assessments of students’ online reasoning, conducted research on fact checkers’ strategies for evaluating digital content, and tested curriculum designed to teach these strategies to secondary and college students. In addition to investigating online reasoning curricula in secondary and college classrooms, Dr. McGrew’s current research focuses on how best to support teachers to learn online reasoning themselves and how to design lessons in online reasoning that are rooted in civic and community issues that students know and care about.

— The Jerk Project
Abstract. The Valuing and Jerk Project.
For the last 40 years we’ve been encouraging women to choose technology careers. But today the quit rate for women in tech is 41% compared to 17% for men. The number of WIT has fallen from 31% in 1990 to 25% in 2014. Research points to cultural dimensions of tech companies that create a work environment of bias, hostility and devalue. Overall women and people of color report a significantly more negative workplace experience. These interpersonal dynamics create more stress and work against feelings of belonging and value. It is not surprising that our research finds that women “thinking of leaving their job” score lower on key factors necessary for women to thrive.
In this talk Karen shares the research and some of the interventions to identify the explicit behaviors which create or undermine the experience of connection and value in the workplace. Field research identified 15 key valuing and 15 key jerk behaviors. A subsequent survey helped to determine the relative value of each behavior for men and women. We share our data and unveil our interventions including fun awareness posters, a self-assessment checklist, and workshop ideas. All work was done by world-wide professional and student volunteers, including many from UMD.

— ARMStrokes: using mobile technology to support everyday stroke rehabilitation
Abstract. Stroke is a major contributor to adult disability in many countries. Stroke often causes long-term disabilities that affect cognitive, physical, and speech functions. Intensive rehabilitation exercise is critical for stroke recovery during the early stage of a stroke. However, only 31 percent of stroke survivors actually complete the recommended exercises due to a variety of factors including lack of motivation. Working closely with stroke survivors and therapists, we investigated the use of mainstream smart phone-based technology in supporting everyday stroke rehabilitation under the supervision of medical professionals. Rather than using specialized sensors to track user movements, we focused on developing an approach without the need for any additional hardware. ARMStrokes supports customized exercise plans to fit each stroke survivor’s specific functionalities in different recovery stages. Longitudinal evaluations with stroke survivors and therapists suggested the application played positive roles in motivating the patients to complete rehabilitation exercises. Design challenges were also identified through the evaluation studies.

— Human-Centered AI: 15 Recommendations for Bridging from Ethics to Practice
Abstract. Human-Centered Artificial Intelligence (HCAI) is a growing theme that seeks to shift the focus from algorithms to the users and many stakeholders in modern information technology systems. This talk and related article (https://dl.acm.org/doi/10.1145/3419764) attempt to bridge the gap between widely discussed ethical principles of Human-Centered AI (HCAI) and practical steps for effective governance. I propose 15 recommendations at three levels of governance: team, organization, and industry. The recommendations are intended to increase the reliability, safety, and trustworthiness of HCAI systems: (1) reliable systems based on sound software engineering practices, (2) safety culture through business management strategies, and (3) trustworthy certification by independent oversight.

— Countering Structural Oppression through Co-design with Residents in Resource-Constrained Communities
Abstract. There has been a recent push in technology design to consider social implications of design — both historical, current, and future. In resource-constrained communities, there have been historical policies and practices (e.g., redlining, overpolicing) that have created concentrated poverty, increased unemployment, and lack of adequate and equitable educational, housing, and health opportunities. However, several local community-based organizations have taken the initiative to address their communities’ challenges regarding issues such as safety and education. In this talk, I will discuss two projects that illustrate how we design technologies, practices, and programs with community residents and organizations to support their efforts to counter social issues that are a result of long-term structural oppression. Specifically, I describe (1) our co-design and evaluation process of a mobile application to support violence prevention efforts by street outreach workers and (2) the evolution of Digital Youth Divas, our program that encourages middle school Black and Latina girls to engage and participate in STEAM experiences. The first project is an example of how to design with organizations that intentionally attempts to counter traditional policing practices by law enforcement by taking a community-led approach to public safety in neighborhoods that experience high violence. The second project illustrates how we can address policies and infrastructure that create barriers for Black and LatinX girls and their families to engage in informal learning opportunities. Insights lead to discussion regarding how we as designers can intentionally support community-based counter structures to make a long-term, sustainable impact on communities that have historically faced systemic oppression.
Bio. Dr. Sheena Erete is an associate professor in the College of Computing and Digital Media at DePaul University. Her research explores the role of technology and design in addressing social issues such as violence, civic engagement, and STEM education in resource constrained communities in Chicago.

— There’s no AI in Team: Evaluating Systems for Multiple-Human Interaction
Abstract. As AI systems become increasingly common, they will need to become more useful and usable as well. One way to make an AI more usable is to embed it into a team structure. Current research on AI-enabled teams generally focuses on functional requirements for the AI, such as task performance or levels of operator intervention required. However, AIs must be designed to optimize the outcomes of the entire sociotechnical system, or else gaps may lead to failures. Looking into the future, AI systems created to assist humans will need to be designed to work with humans, or within human teams. We do not argue that AI systems in human teams need to be human-like, but there are particular behaviors and non task-related requirements that are necessary for them to operate harmoniously as part of a team. This research effort uses a novel input-process-emergent state-output-input (IPEOI) model with four levels to describe what is needed for AI-enabled team performance. In this talk, I will describe the work our multidisciplinary team has done to define the problem of AI-human teaming and provide a preliminary look at our proposed model. This work has been done in collaboration with Breana Carter-Browne (ARLIS), Susannah Paletz (iSchool), Melissa Carraway (iSchool PhD student), Sarah Vahlkamp (iSchool PhD student), Jana Schwartz (ARLIS), and Polly O’Rourke (ARLIS).

— The Impact of Tool Design and Media Portrayals in the Success of Activist DDoS Attacks
Abstract. This talk explores the role of tool design and media coverage in the relative success of Operation Payback and earlier activist distributed denial-of-service (DDOS) actions. Through a close reading of changes in the tool’s interface and functionality across several iterations, the article considers the evolution of the Low Orbit Ion Cannon (LOIC) DDOS tool, from one that appealed to a small, inwardly focused community to one that engaged with a larger population. The article further considers Anonymous’s contribution to the reframing of DDOS actions from a tool of direct action to a tool of media manipulation and identity construction as well as the news media’s role in encouraging individuals to participate in the Operation Payback actions.
