| 2026 | Designing for Sustained Motivation: A Review of Self-Determination Theory in Behaviour Change TechnologiesabstractAbstract Recent years have seen a surge in applications and technologies aimed at motivating users to achieve personal goals and improve their wellbeing. However, these often fail to promote long-term behaviour change, and sometimes even backfire. We consider how self-determination theory (SDT), a metatheory of human motivation and wellbeing, can help explain why such technologies fail, and how they may better help users internalize the motivation behind their goals and make enduring changes in their behaviour. In this work, we systematically reviewed 15 papers in the ACM Digital Library that apply SDT to the design of behaviour change technologies (BCTs). We identified 50 suggestions for design features in BCTs, grounded in SDT, that researchers have applied to enhance user motivation. However, we find that SDT is often leveraged to optimize engagement with the technology itself rather than with the targeted behaviour change per se. When interpreted through the lens of SDT, the implication is that BCTs may fail to cultivate sustained changes in behaviour, as users’ motivation depends on their enjoyment of the intervention, which may wane over time. An underexplored opportunity remains for designers to leverage SDT to support users to internalize the ultimate goals and value of certain behaviour changes, enhancing their motivation to sustain these changes in the long term.

| 2025 | The Digital Attention Heuristics: Supporting the User's Attention by DesignabstractThe HCI research community has traditionally considered digital wellbeing an end-user responsibility, designing tools for digital self-control that support them to self-regulate their usage of apps and Web sites. Yet, these attempts are often ineffective in the long term, as many tech companies still adopt “attention-capture” designs that compromise users’ sense of agency and self-control. Taking a complementary perspective, this article presents a set of eight heuristics to create user interfaces that preserve and respect user attention by design . The heuristics stem from a systematic literature review and are grounded in the three fundamental psychological needs defined by the self-determination theory, i.e., autonomy, competence, and relatedness. In addition to being informed by theory and research, each heuristic is accompanied by practical strategies and real-world examples, offering designers actionable guidelines to value people’s attention in user interfaces.

| 2024 | "I finally felt I had the tools to control these urges": Empowering Students to Achieve Their Device Use Goals With the Reduce Digital Distraction WorkshopabstractDigital self-control tools (DSCTs) help people control their time and attention on digital devices, using interventions like distraction blocking or usage tracking. Most studies of DSCTs’ effectiveness have focused on whether a single intervention reduces time spent on a single device. In reality, people may require combinations of DSCTs to achieve more subjective goals across multiple devices. We studied how DSCTs can address individual needs of university students (n = 280), using a workshop where students reflect on their goals before exploring relevant tools. At 1-3 month follow-ups, 95% of respondents still used at least one type of DSCT, typically applied across multiple devices, and there was substantial variation in the tool combinations chosen. We observed a large increase in self-reported digital self-control, suggesting that providing a space to articulate goals and self-select appropriate DSCTs is a powerful way to support people who struggle to self-regulate digital device use.

| 2023 | SwitchTube: A Proof-of-Concept System Introducing "Adaptable Commitment Interfaces" as a Tool for Digital WellbeingabstractYouTube has many features, such as homepage recommendations, that encourage users to explore its vast library of videos. However, when users visit YouTube with a specific intention, e.g., learning how to program in Python, these features to encourage exploration are often distracting. Prior work has innovated ‘commitment interfaces’ that restrict social media but finds that they often indiscriminately block needed content. In this paper, we describe the design, development, and evaluation of an ‘adaptable commitment interface,’ the SwitchTube mobile app, in which users can toggle between two interfaces when watching YouTube videos: Focus Mode (search-first) and Explore Mode (recommendations-first). In a three-week field deployment with 46 US participants, we evaluate how the ability to switch between interfaces affects user experience, finding that it provides users with a greater sense of agency, satisfaction, and goal alignment. We conclude with design implications for how adaptable commitment interfaces can support digital wellbeing. Kai Lukoff, Ulrik Lyngs, Karina Shirokova, Raveena Rao, Larry Tian, Himanshu Zade, Sean A.

| 2023 | Defining and Identifying Attention Capture Deceptive Designs in Digital InterfacesabstractMany tech companies exploit psychological vulnerabilities to design digital interfaces that maximize the frequency and duration of user visits. Consequently, users often report feeling dissatisfied with time spent on such services. Prior work has developed typologies of damaging design patterns (or dark patterns) that contribute to financial and privacy harms, which has helped designers to resist these patterns and policymakers to regulate them. However, we are missing a collection of similar problematic patterns that lead to attentional harms. To close this gap, we conducted a systematic literature review for what we call ‘attention capture damaging patterns’ (ACDPs). We analyzed 43 papers to identify their characteristics, the psychological vulnerabilities they exploit, and their impact on digital wellbeing. We propose a definition of ACDPs and identify eleven common types, from Time Fog to Infinite Scroll. Our typology offers technologists and policymakers a common reference to advocate, design, and regulate against attentional harms. Alberto Monge Roffarello, Kai Lukoff, Luigi De Russis |

| 2022 | "I Don't Even Remember What I Read": How Design Influences Dissociation on Social MediaabstractMany people have experienced mindlessly scrolling on social media. We investigated these experiences through the lens of normative dissociation: total cognitive absorption, characterized by diminished self-awareness and reduced sense of agency. To explore user experiences of normative dissociation and how design affects the likelihood of normative dissociation, we deployed Chirp, a custom Twitter client, to 43 U.S. participants. Experience sampling and interviews revealed that sometimes, becoming absorbed in normative dissociation on social media felt like a beneficial break. However, people also reported passively slipping into normative dissociation, such that they failed to absorb any content and were left feeling like they had wasted their time. We found that designed interventions–including custom lists, reading history labels, time limit dialogs, and usage statistics–reduced normative dissociation. Our findings demonstrate that interaction designs intended to capture attention likely do so by harnessing people’s natural inclination to seek normative dissociation experiences. This suggests that normative dissociation may be a more productive framing than addiction for discussing social media overuse.

| 2022 | Monitoring Screen Time or Redesigning It?: Two Approaches to Supporting Intentional Social Media UseabstractExisting designs helping people manage their social media use include: 1) external supports that monitor and limit use; 2) internal supports that change the interface itself. Here, we design and deploy Chirp, a mobile Twitter client, to independently examine how users experience external and internal supports. To develop Chirp, we identified 16 features that influence users’ sense of agency on Twitter through a survey of 129 participants and a design workshop. We then conducted a four-week within-subjects deployment with 31 participants. Our internal supports (including features to filter tweets and inform users when they have exhausted new content) significantly increased users’ sense of agency, while our external supports (a usage dashboard and nudges to close the app) did not. Participants valued our internal supports and said that our external supports were for “other people.” Our findings suggest that design patterns promoting agency may serve users better than screen time tools.

| 2022 | The Goldilocks level of support: Using user reviews, ratings, and installation numbers to investigate digital self-control toolsabstractMuch effort has been invested in designing digital systems that keep people ‘hooked’. By contrast, comparatively little is known about how designers can support people in re-gaining control. Online, however, hundreds of apps and browser extensions promise to help people self-regulate use of digital devices. Reviews and popularity metrics for these digital self-control tools (DSCTs) can indicate which design patterns are useful in the wild. Moreover, they reveal how platforms like Android and iOS differ in the ecosystems they enable for DSCTs, which has important implications for end users. We analysed reviews, installation numbers, and ratings for 334 DSCTs on the Google Play, Chrome Web, and Apple App stores, investigating what user reviews reveal about usage contexts and key design challenges, and how functionality relates to popularity metrics. Our thematic analysis of 1,529 reviews (sampled from a data set of 53,978 distinct reviews scraped in March 2019) found that DSCTs are seen as highly important for focusing on less instantly rewarding tasks when digital distractions are easily available. Users seek DSCTs that adapt to their personal definitions of distraction, and provide support that is sufficient to change behaviour without feeling too coercive. Reviewers suggested combining design patterns to provide a level of support that is ‘just right’. This was mirrored in the ratings, where tools that combine different types of design patterns (e.g., website blocking and goal reminders) tended to receive higher ratings than those implementing a single type. We discuss implications for research and design, including how design patterns in DSCTs interact, and how psychological reactance to DSCTs can be reduced.

| 2021 | How the Design of YouTube Influences User Sense of AgencyabstractIn the attention economy, video apps employ design mechanisms like autoplay that exploit psychological vulnerabilities to maximize watch time. Consequently, many people feel a lack of agency over their app use, which is linked to negative life effects such as loss of sleep. Prior design research has innovated external mechanisms that police multiple apps, such as lockout timers. In this work, we shift the focus to how the internal mechanisms of an app can support user agency, taking the popular YouTube mobile app as a test case. From a survey of 120 U.S. users, we find that autoplay and recommendations primarily undermine sense of agency, while playlists and search support it. From 13 co-design sessions, we find that when users have a specific intention for how they want to use YouTube they prefer interfaces that support greater agency. We discuss implications for how designers can help users reclaim a sense of agency over their media use. Kai Lukoff, Ulrik Lyngs, Himanshu Zade, J. Vera Liao, James Choi, Kaiyue Fan, Sean A.

| 2020 | From Ancient Contemplative Practice to the App Store: Designing a Digital Container for MindfulnessabstractHundreds of popular mobile apps today market their ties to mindfulness. What activities do these apps support and what benefits do they claim? How do mindfulness teachers, as domain experts, view these apps? We first conduct an exploratory review of 370 mindfulness-related apps on Google Play, finding that mindfulness is presented primarily as a tool for relaxation and stress reduction. We then interviewed 15 U.S. mindfulness teachers from the therapeutic, Buddhist, and Yogic traditions about their perspectives on these apps. Teachers expressed concern that apps that introduce mindfulness only as a tool for relaxation neglect its full potential. We draw upon the experiences of these teachers to suggest design implications for linking mindfulness with further contemplative practices like the cultivation of compassion. Our results also speak to the importance of coherence in design: that the metaphors and mechanisms of a technology align with the underlying principles it follows.

| 2020 | 'I Just Want to Hack Myself to Not Get Distracted': Evaluating Design Interventions for Self-Control on FacebookabstractBeyond being the world's largest social network, Facebook is for many also one of its greatest sources of digital distraction. For students, problematic use has been associated with negative effects on academic achievement and general wellbeing. To understand what strategies could help users regain control, we investigated how simple interventions to the Facebook UI affect behaviour and perceived control. We assigned 58 university students to one of three interventions: goal reminders, removed newsfeed, or white background (control). We logged use for 6 weeks, applied interventions in the middle weeks, and administered fortnightly surveys. Both goal reminders and removed newsfeed helped participants stay on task and avoid distraction. However, goal reminders were often annoying, and removing the newsfeed made some fear missing out on information. Our findings point to future interventions such as controls for adjusting types and amount of available information, and flexible blocking which matches individual definitions of 'distraction'.

| 2019 | Self-Control in Cyberspace: Applying Dual Systems Theory to a Review of Digital Self-Control ToolsabstractMany people struggle to control their use of digital devices. However, our understanding of the design mechanisms that support user self-control remains limited. In this paper, we make two contributions to HCI research in this space: first, we analyse 367 apps and browser extensions from the Google Play, Chrome Web, and Apple App stores to identify common core design features and intervention strategies afforded by current tools for digital self-control. Second, we adapt and apply an integrative dual systems model of self-regulation as a framework for organising and evaluating the design features found. Our analysis aims to help the design of better tools in two ways: (i) by identifying how, through a well-established model of self-regulation, current tools overlap and differ in how they support self-control; and (ii) by using the model to reveal underexplored cognitive mechanisms that could aid the design of new tools.

| 2018 | TableChat: Mobile Food Journaling to Facilitate Family Support for Healthy EatingabstractSupport from family members is an important determinant of health. In this work, we probe opportunities for facilitating family support with TableChat, a chat-based mobile application for food journaling. Leveraging food as a test case of family support, TableChat virtually extends the experience of bonding over the dinner table. We surveyed 158 people about their existing family support practices and deployed TableChat with 10 families in the field. We found that tangible support was the most common form of support shared in TableChat and also the most appreciated by participants. However, we found that participants valued not only supportive actions taken by their family members, but also those deliberately not taken (e.g., not buying junk food). Finally, families reported that journaling meals eaten apart aided the exchange of support, satisfied curiosity, and provided a "check-in" that everything was alright, whereas journaling meals eaten together felt redundant. We conclude with a framework that illustrates how informatics tools can be designed to complement rather than compete with existing family interactions. Kai Lukoff, Taoxi Li, Brian Y. Lim |

| 2017 | Gender Norms and Attitudes about Childcare Activities Presented on Father BlogsabstractFather involvement is important for child well-being. However, fathers still do significantly less childcare than mothers, due in part to traditional gender norms. This research investigates whether incorporating do-it-yourself (DIY) language and imagery into parenting blogs is an effective mechanism for boosting fathers' willingness to perform childcare activities. We conducted a between-subjects experiment with 374 participants in the U.S. who responded to ten parenting blog posts. Subjects were randomized to view posts with either DIY or neutral language and either routine childcare activities (e.g., changing diapers) or interactive ones (e.g., finger painting). Results show that DIY language actually decreases a father's willingness to do a childcare activity. Further, fathers underestimate how socially appropriate it is for them to perform childcare activities and this misperception relates to their willingness to get involved. We draw on social norms literature to recommend next steps for designing interfaces to support father involvement in childrearing. Kai Lukoff, Carol Moser, Sarita Yardi Schoenebeck |
