People engage in self-tracking with diverse data collection and visualisation needs and preferences. Customisable self-tracking tools offer the potential to support individualized preferences by letting people make changes to the aesthetics and functionality of tracker displays. In this paper, we use the customisation options offered by the displays of commercial fitness smartwatches as a lens to investigate when, why and how 386 self-trackers engage in customisations in their daily lives. We find that people largely customise their trackers’ display frequently, multiple times a day, or not at all, with frequent customisations reflecting situational data, aesthetic and personal meaning needs. We discuss implications for the design of tracking tools aiming to support customisation and discuss the utility of customisations towards goal scaffolding and maintaining interest in tracking.

Datafication refers to the practices through which children’s online actions are pervasively recorded, tracked, aggregated, analysed, and exploited by online services in ways including behavioural engineering and monetisation. Previous research has shown that not only do children care significantly about various aspects of datafication, but they demand a chance to take action. Through 10 co-design sessions with 53 children, we examined how children in the UK want to be supported to cope with the datafication practices. Our findings provide insights for creating age-appropriate support for children’s algorithmic literacy development, highlighting and unpacking the importance of no one-size-fitting-all designs to support children’s coping with datafication. We contribute a first understanding of how children aged 7–14 would like to be supported with datafication and what future data-driven digital experiences should be like for them, who demand a shift of the current data ecosystem towards a more humane-by-design and autonomy-supportive future.

Messaging is a ubiquitous digital communication medium. It is also a minimal medium of communication because of its inability to convey immediate feedback, tone, facial expressions, hesitations, and pauses, or follow the train of the other person’s thoughts. This paper combines quantitative and qualitative approaches for analyzing richer forms of typing indicators in messaging interfaces, such as showing text as it is typed. By assessing users’ subjective workload and interpreting these findings in the context of users’ experiences, we found that more expressive typing indicators were perceived as “rich in communication”, as they helped people communicate more allowing for closer connections. These indicators also increased users’ perceived co-presence. In addition, our research suggests there may be benefits of designing customized typing indicators for relationship maintenance and task-based communication.

Social media platforms use content moderation to reduce and remove problematic content. However, much of the discourse on the benefits and pitfalls of moderation has so far focused on users in the West. Little is known about how users in the Global South interact with the humans and algorithms behind opaque moderation systems. To fill this gap, we conducted interviews with 19 Bangladeshi social media users who received restrictions for violating community standards on Facebook. We found that the users perceived the underlying human-AI infrastructure to imbibe coloniality in the form of amplifying power relations, centering Western norms, and perpetuating historical injustices and erasure of minoritized expressions. Based on the findings, we establish that the current moderation systems often propagate historical power relations and patterns of oppression, and discuss ways to rethink moderation in a fundamentally decolonial way.

From ride-hailing to car rentals, consumers are often presented with eco-friendly options. Beyond highlighting a “green” vehicle and CO2 emissions, CO2 equivalencies have been designed to provide understandable amounts; we ask which equivalencies will lead to eco-friendly decisions. We conducted five ride-hailing scenario surveys where participants picked between regular and eco-friendly options, testing equivalencies, social features, and valence-based interventions. Further, we tested a car-rental embodiment to gauge how an individual (needing a car for several days) might behave versus the immediate ride-hailing context. We find that participants are more likely to choose green rides when presented with additional information about emissions; CO2 by weight was found to be the most effective. Further, we found that information framing—be it individual or collective footprint, positive or negative valence—had an impact on participants’ choices. Finally, we discuss how our findings inform the design of effective interventions for reducing car-based carbon-emissions.

New printing strategies have enabled 3D-printed materials that imitate traditional textiles. These filament-based textiles are easy to fabricate but lack the look and feel of fiber textiles. We seek to augment 3D-printed textiles with needlecraft to produce composite materials that integrate the programmability of additive fabrication with the richness of traditional textile craft. We present PunchPrint: a technique for integrating fiber and filament in a textile by combining punch needle embroidery and 3D printing. Using a toolpath that imitates textile weave structure, we print a flexible fabric that provides a substrate for punch needle production. We evaluate our material’s robustness through tensile strength and needle compatibility tests. We integrate our technique into a parametric design tool and produce functional artifacts that show how PunchPrint broadens punch needle craft by reducing labor in small, detailed artifacts, enabling the integration of openings and multiple yarn weights, and scaffolding soft 3D structures.

Understanding how to design and implement equity-based approaches to technology-rich learning can lead to increased and diversified participation in computing. Do-it-yourself (DIY) and maker approaches to interactive technology learning have been hailed as potential equalizers of science, technology, engineering, and math (STEM) education for underserved youth, a narrative challenged by scholarship that has shown that if not designed carefully, making can be exclusionary and hegemonic. Equity-based approaches to making have identified the crucial role of community educators to prioritize community assets and learner participation. We studied educators’ strategies and youth outcomes in four afterschool maker programs in urban recreation centers. Community educators used several equity-based strategies to engage youth that included: identifying their interests through direct conversation and indirect signaling, customizing program activities to respond to interests, and encouraging self-expression and authenticity. These strategies led to increased social connections among youth, and increased technology self-efficacy and project ownership.

Fingertip force control plays an important role in learning motor skills. Exoskeleton gloves have been developed to assist with fingertip force control, but having the equipment on the fingers interferes with finger motion control and tactile sensation. Thus, we present a system for assisting with voluntary fingertip force control that does not require any devices to be worn on the fingers. In this study, we focused particularly on lateral pinch force, which is grip force achieved with the pad of the thumb and the lateral surface of the index finger to grasp objects. We use active bio-acoustic sensing to estimate voluntary pinch force with piezo elements attached to the back of the hand and electrical muscle stimulation (EMS) to the forearm to control involuntary pinch force in a closed-loop system. We developed three prototypes and conducted user studies to investigate whether our system can assist with pinch force control under several target forces, from weak to strong. Our user studies showed that the combination of active bio-acoustic sensing and EMS can assist users in maintaining the pinch force closer to the target force.

Immersive authoring tools allow users to intuitively create and manipulate 3D scenes while immersed in Virtual Reality (VR). Collaboratively designing these scenes is a creative process that involves numerous edits, explorations of design alternatives, and frequent communication with collaborators. Version Control Systems (VCSs) help users achieve this by keeping track of the version history and creating a shared hub for communication. However, most VCSs are unsuitable for managing the version history of VR content because their underlying line differencing mechanism is designed for text and lacks the semantic information of 3D content; and the widely adopted commit model is designed for asynchronous collaboration rather than real-time awareness and communication in VR. We introduce VRGit, a new collaborative VCS that visualizes version history as a directed graph composed of 3D miniatures, and enables users to easily navigate versions, create branches, as well as preview and reuse versions directly in VR. Beyond individual uses, VRGit also facilitates synchronous collaboration in VR by providing awareness of users’ activities and version history through portals and shared history visualizations. In a lab study with 14 participants (seven groups), we demonstrate that VRGit enables users to easily manage version history both individually and collaboratively in VR.

Many of our activities rely on tactile feedback perceived through mechanoreceptors in our skin. While visual and auditory devices provide immersive experiences, cutaneous feedback devices are typically limited in the range of sensations they provide and are hence usually used and tested on relatively simple synthetic surfaces. We present a device designed in a human-centered process, triggering the mechanoreceptors sensitive to pressure, low-frequency vibrations, and high-frequency vibrations, enabling one to experience touch of complex real-world surfaces. The device is based on a parallel manipulator and a pin-array, that operate simultaneously at 200Hz and emulate coarse and fine geometrical features, respectively. The decomposition into coarse and fine features, alongside the high operation frequency, enable simulation of virtual surfaces. This was corroborated via experiments on complex real-world surfaces via both a quantitative recognition test and a usability questionnaire. We believe that this design can be incorporated in numerous applications.
