Abstract: Geographical propagation phenomena occur in multiple domains, such as in epidemiology and social media. Propagation dynamics are often complex, and visualizations play a key role in helping subject-matter experts understand and analyze them. However, there is little empirical data about the effectiveness of the various strategies used to visualize geographical propagation. To fill this gap, we conduct an experiment to evaluate the effectiveness of three strategies: an animated map, small-multiple maps, and a single map with glyphs. We compare them under five tasks that vary in one of the following dimensions: propagation scope, direction, speed, peaks, and spatial jumps. Our results show that small-multiple maps perform best overall, but that the effectiveness of each visualization varies depending on the task considered.

Abstract: Self-harm is a prevalent issue amongst young people, yet it is thought around 40% will never seek professional help due to stigma surrounding it. It is generally a way of coping with emotional distress and can have a range of triggers which are highly heterogeneous to the individual. In a move towards enhancing the accessibility of personalized interventions for self-harm, we undertook a three-stage study. We first conducted interviews with 4 counsellors in self-harm to understand how they clinically respond to self-harm triggers. We then ran a survey with 37 young people, to explore perceptions of mobile sensing, and current and future uses for smartphone-based interventions. Finally, we ran a workshop with 11 young people to further explore how a context-aware self-management application might be used to support them. We contribute an in-depth understanding of how triggers for self-harm might be identified and subsequently predicted and prevented using mobile-sensing technology.

Abstract: A months-long hike of the Appalachian Trail often involve long-term preparation and life-altering decisions. Would-be hikers leverage institutional knowledge from literature and online forums to physically and mentally prepare for such an arduous hike. Their use of social platforms provide useful insights on motivations for undertaking the thru-hike, how they deal with unexpected conditions on the trail and understand choices made in conditions of scarcity. By analyzing over 100,000 Reddit posts and comments in r/AppalachianTrail and applying a Sense of Community theory, we sought to understand hikers' identity as community members, how their emotional and practical needs are met, and how they evolve. We found that the role and language of thru-hikers change as they progress from pre-hike, on-hike, and post-hike stages, from a questioner early on, to an expert post-hike. We conclude with design recommendations to support offline communities online.

Abstract: One of the challenges faced by healthy older adults is experiencing feelings of not "being-seen". Companion robots, commonly designed with zoomorphic or humanoid appearance show success among clinical older adults, but healthy older adults find them degrading. We present the design and implementation of a novel non-humanoid robot. The robot's primary function is a cognitive word game. Social interaction is conveyed as a secondary function, using non-verbal gestures, inspired by dancers' movement. In a lab study, 39 healthy older adults interacted with the prototype in 3 conditions: Companion-Function; Game-Function; and No-Function. Results show the non-verbal gestures were associated with feelings of "being-seen", and willingness to accept the robot into their home was influenced by its function, with game significantly higher than companion. We conclude that robot designers should further explore the potential of non-humanoid robots as a new class of companion robots, with a primary function that is not companionship.

Abstract: Tactile materials are powerful teaching aids for students with visual impairments (VIs). To design these materials, designers must use modeling applications, which have high learning curves and rely on visual feedback. Today, Orientation and Mobility (O&M) specialists and teachers are often responsible for designing these materials. However, most of them do not have professional modeling skills, and many are visually impaired themselves. To address this issue, we designed Molder, an accessible design tool for interactive tactile maps, an important type of tactile materials that can help students learn O&M skills. A designer uses Molder to design a map using tangible input techniques, and Molder provides auditory feedback and high-contrast visual feedback. We evaluated Molder with 12 participants (8 with VIs, 4 sighted). After a 30-minute training session, the participants were all able to use Molder to design maps with customized tactile and interactive information.

Abstract: Analyzing queries from search engines and intelligent assistants is difficult. A key challenge is organizing queries into interpretable, context-preserving, representative, and flexible groups. We present structural templates, abstract queries that replace tokens with their linguistic feature forms, as a query grouping method. The templates allow analysts to create query groups with structural similarity at different granularities. We introduce Tempura, an interactive tool that lets analysts explore a query dataset with structural templates. Tempura summarizes a query dataset by selecting a representative subset of templates to show the query distribution. The tool also helps analysts navigate the template space by suggesting related templates likely to yield further explorations. Our user study shows that Tempura helps analysts examine the distribution of a query dataset, find labeling errors, and discover model error patterns and outliers.

Abstract: We describe a Research through Design project-Curious Cycles-a collection of objects and interactions which encourage people to be in close contact with their menstruating body. Throughout a full menstrual cycle, five participants used Curious Cycles to look at their bodies in unfamiliar ways and to touch their bodily fluids, specifically, menstrual blood, saliva, and cervical mucus. The act of touching and looking led to the construction of new knowledge about the self and to a nurturing appreciation for the changing body. Yet, participants encountered and reflected upon frictions within themselves, their home, and their social surroundings, which stem from societal stigma and preconceptions about menstruation and bodily fluids. We call for and show how interaction design can engage with technologies that mediate self-touch as a first step towards reconfiguring the way menstruating bodies are treated in society.

Abstract: Excessive smartphone use has negative effects on our social relations as well as on our mental and psychological health. Most of the previous work to avoid these negative effects is based on a top-down approach such as restricting or limiting users' use of smartphones. Diverging from previous work, we followed a bottom-up approach to understand the practice of smartphone use in public settings from the users' perspective. We conducted observations in four coffeehouses, six focus group sessions with 46 participants and three design workshops with 15 designers. We identified five themes that help better understand smartphone use behavior in public settings and four alternative design approaches to mediate this behavior, namely enlighteners, preventers, supporters, and compliers. We discuss the implications of these themes and approaches for designing future interactive technologies aimed at mediating excessive smartphone use behavior.

Abstract: We present a compact broadband linear actuator, Chasm, that renders expressive haptic feedback on wearable and handheld devices. Unlike typical motor-based haptic devices with integrated gearheads, Chasm utilizes a miniature leadscrew coupled to a motor shaft, thereby directly translating the high-speed rotation of the motor to the linear motion of a nut carriage without an additional transmission. Due to this simplicity, Chasm can render low-frequency skin-stretch and high-frequency vibrations, simultaneously and independently. We present the design of the actuator assembly and validate its electromechanical and perceptual performance. We then explore use cases and show design solutions for embedding Chasm in device prototypes. Finally, we report investigations with Chasm in two VR embodiments, i.e., in a headgear band to induce locomotion cues and in a handheld pointer to enhance dynamic manual interactions. Our explorations show wide use for Chasm in enhancing user interactions and experience in virtual and augmented settings.

Abstract: Public interactive displays (PID) are a promising technology for providing information and collecting feedback in public spaces. Research on PIDs has shown that, like all public displays, their efficacy is reduced by display blindness. Rather than increase the visual attention-grabbing nature of PIDs, we propose that additional understanding is required around how and when these displays are able to offer value to users. We tackle this through a systematic analysis of PID studies published in the literature, which led to 9 aspects of value across 4 factors: people, location, community, and time. We discuss the identified aspects and their utility for the design of PIDs through a review of our own deployments carried out by 4 different labs across 5 countries. We conclude with a set of recommendations for identifying and optimising the intended value of future PIDs.
Title: MagneLayer: Force Field Fabrication by Layered Magnetic Sheets

Venue: Proceedings of the 2020 CHI Conference on Human Factors in Computing Systems

Abstract: Magnets are very useful for the rapid prototyping of haptic interactions. However, it is difficult to arrange fine and complex magnetic fields rapidly. Therefore, we invented a method for fabricating complex geometric magnetic patterns by overlaying multiple magnetic rubber sheets. This method resolves the tradeoff between magnetized pattern complexity and the time required for magnetization. By layering multiple magnetic sheets that have simple magnetic patterns, various types of geometric magnetic patterns, such as checkered and diamond ones, can be generated on the top surface. By applying superposed magnetic fields, various types of tactile stimuli and haptic interaction can be created rapidly. Furthermore, the superposed magnetic fields can be changed dynamically by rotating the layered magnetic sheets. In this paper, we clarify the material requirements and describe the design method for creating these geometric magnetic patterns. We also demonstrate several of their applications.

Abstract: This paper joins the growing body of work in postcolonial computing in HCI, and critically examines the impacts of online social media on the urban architecture in the Global South. Based on our nine-month long ethnography at eight residential areas in Dhaka, Bangladesh, this paper reports how online fame drives local users to produce digital images of their houses mimicking various Western standards, which in turn, brings changes to the organization, aesthetics, and functions of domestic spaces. This paper also describes how such digital image mediated transformations to local architecture are diminishing traditional spaces, altering their usual functions, and limiting the movement of many women inside their home. Drawing from a rich body of literature in postcolonialism, critical image theory, architecture, and Islamic feminism, we explain how these practices demonstrate a subaltern experience of using social media in the Global South. We further discuss design implications to both HCI and architecture to address these issues, and connect our findings to the broader agendas of HCI around social justice and global development.

Abstract: Personal smart devices have demonstrated a variety of efficient techniques for pointing and selecting on physical displays. However, when migrating these input techniques to augmented reality, it is both unclear what the relative performance of different techniques will be given the immersive nature of the environment, and it is unclear how viewport-based versus world-based pointing methods will impact performance. To better understand the impact of device and viewing perspectives on pointing in augmented reality, we present the results of two controlled experiments comparing pointing conditions that leverage various smartphone- and smartwatch-based external display pointing techniques and examine viewport-based versus world-based target acquisition paradigms. Our results demonstrate that viewport-based techniques offer faster selection and that both smartwatch- and smartphone-based pointing techniques represent high-performance options for performing distant target acquisition tasks in augmented reality.

Abstract: The social media environment in China has become the dominant source of information and news over the past decade. This news environment has naturally suffered from challenges related to mis- and dis-information, encumbered by an increasingly complex landscape of factors and players including social media services, fact-checkers, censorship policies, and astroturfing. Interviews with 44 Chinese WeChat users were conducted to understand how individuals perceive misinformation and how it impacts their news consumption practices. Overall, this work exposes the diverse attitudes and coping strategies that Chinese users employ in complex social media environments. Due to the complex nature of censorship in China and participants' lack of understanding of censor-ship, they expressed varied opinions about its influence on the credibility of online information sources. Further, although most participants claimed that their opinions would not be easily swayed by astroturfers, many admitted that they could not effectively distinguish astroturfers from ordinary Internet users. Participants' inability to make sense of comments found online lead many participants to hold pro-censorship attitudes: the Government's Dividend.

Abstract: We examine a leaderless social movement characterized by participants' autonomy and the absence of leaders and organizations. We conducted a participant observation study of the Anti-ELAB movement in Hong Kong. Focusing on the organization of a protest march, we collected thousands of lines of discourse in the LIHKG Forum and the Telegram instant messaging system. Our grounded theory analysis revealed hundreds of groups acting within a symbiotic network. Participants promoted an ethos of empowering individual participants and groups to act autonomously. At the same time, participants' extensive use of hyperlinks and polls orchestrated a coherent social movement. We discuss how this novel formation can mediate successful leaderless movements.

Abstract: Despite the benefits of team diversity, individuals often choose to work with similar others. Online team formation systems have the potential to help people assemble diverse teams. Systems can connect people to collaborators outside their networks, and features can quantify and raise the salience of diversity to users as they search for prospective teammates. But if we build a feature indicating diversity into the tool, how will people react to it? Two experiments manipulating the presence or absence of a "diversity score" feature within a teammate recommender demonstrate that, when present, individuals avoid collaborators who would increase team diversity in favor of those who lower team diversity. These results have important practical implications. Though the increased access to diverse teammates provided by recommender systems may benefit diversity, designers are cautioned against creating features that raise the salience of diversity as this information may undermine diversity.

Abstract: The future of work is speculated to undergo profound change with increased automation. Predictable jobs are projected to face high susceptibility to technological developments. Many economies in Global South are built around outsourcing and manual labour, facing a risk of job insecurity. In this paper, we examine the perceptions and practices around automated futures of work among a population that is highly vulnerable to algorithms and robots entering rule-based and manual domains: vocational technicians. We present results from participatory action research with 38 vocational technician students of low socio-economic status in Bangalore, India. Our findings show that technicians were unfamiliar with the growth of automation, but upon learning about it, articulated an emic vision for a future of work in-line with their value systems. Participants felt excluded by current technological platforms for skilling and job-seeking. We present opportunities for technology industry and policy makers to build a future of work for vulnerable communities.

Abstract: Participatory video (PV) is an established practice for enabling communities to "speak truth to power" and has been widely used by local, national and international Non-Governmental Organizations (NGOs). However, the digital media landscape has changed dramatically since PV became widely accessible with the rise of the camcorder in the 1980s. Current media practices have evolved considerably since, yet PV remains essentially unchanged. We report on an investigation of current PV practices and reflect on these in terms of what the future for PV holds. We conducted interviews with staff at a global humanitarian network who directly and indirectly engage in community story capture; and explore their reflections on the potentials and barriers to PV use. We propose a new vision for PV that draws on current visual media production, consumption and distribution technologies and practices, and propose principles on which PV 2.0, a new generation of Participatory Video can be founded.
