Abstract: Online collaborative writing is an increasingly common practice. Despite its positive effect on productivity and quality of work, it poses challenges to co-authors in remote settings because of limitations in conversational grounding and activity awareness. This paper presents Eye-Write, a novel system which allows two co-authors to see at will the location of their partner's gaze within a text editor. To investigate the effect of shared gaze on collaboration, we conducted a study on synchronous remote collaborative writing in academic settings with 20 dyads. Gaze sharing improved five aspects of perceived collaboration quality: mutual understanding, level of joint attention, flow of communication, level of negotiation, and awareness of the co-author's activity. Furthermore, dyads whose participants deactivated the gaze visualization showed a smaller degree of collaboration. Our findings offer insights for future text editors by outlining the benefits of at-will gaze sharing in collaborative writing.

Abstract: Students and hobbyists build embedded systems that combine sensing, actuation and microcontrollers on solderless breadboards. To help students debug such circuits, experienced teachers apply visual inspection, targeted measurements, and circuit modifications to diagnose and localize the problem(s). However, experienced helpers may not always be available to review student projects in person. To enable remote debugging of circuit problems, we introduce Heimdall, a remote electronics workbench that allows experts to visually inspect a student's circuit; perform measurements; and to re-wire and inject test signals. These interactions are enabled by an actuated inspection camera; an augmented breadboard that enables flexible configuration of row connectivity and measurement/injection lines; and a web-based UI that teachers can use to perform measurements through interaction with the captured images. We demonstrate that common issues arising in embedded electronics classes can be successfully diagnosed remotely and report on preliminary user feedback from teaching assistants who frequently debug circuits.

Keywords: brokerage, computing education, learning ecologies, university-school partnerships

Abstract: The state of computing education in the UK is described as "patchy and fragile" with universities tasked to provide further support to schools. However, little guidance exists towards the provision of this support. To explore the development of university-school partnerships, we present findings of an extended educational engagement coordinated by Newcastle University, as part of the national "Create, Learn and Inspire with the micro:bit and the BBC" initiative. Following an action research approach, we explore the experiences of undergraduate students, schoolteachers and an educational broker through the process, including recruitment, content development, and delivery of over 30 computing lessons by nine undergraduates. We identify a number of design considerations towards the development of High Opportunity Progression Ecosystems for the improvement of computing education, such as student identity, workload model,and process visibility. We then discuss the potential role of technology in infrastructuring support for university-school partnerships

Abstract: Recent research suggests that a robot's motors make sounds that can influence users' perception of the robot's characteristics. To more deeply understand users' associations with specific sonic characteristics, we adapted methods from sensory science including Check All That Apply (CATA) questions and Polarized Sensory Positioning (PSP) to tease out small differences in motor sounds in an online survey. These methods are straightforward for untrained people to do in an online setting, mathematically rigorous, and can explore a variety of subtle auditory and perceptual stimuli. We describe how to use these methods, interpret the results with several intuitive visual representations, and show that the results align with a previous study of the same dataset. We close by discussing benefits and limitations of applying these methods to study subtle phenomena in the HCI community.

Keywords: touchscreen, hierarchical list navigation, pinch gesture

Abstract: Intensive exploration and navigation of hierarchical lists on smartphones can be tedious and time-consuming as it often requires users to frequently switch between multiple views. To overcome this limitation, we present PinchList, a novel interaction design that leverages pinch gestures to support seamless exploration of multi-level list items in hierarchical views. With PinchList, sub-lists are accessed with a pinch-out gesture whereas a pinch-in gesture navigates back to the previous level. Additionally, pinch and flick gestures are used to navigate lists consisting of more than two levels. We conduct a user study to refine the design parameters of PinchList such as a suitable item size, and quantitatively evaluate the target acquisition performance using pinch-in/out gestures in both scrolling and non-scrolling conditions. In a second study, we compare the performance of PinchList in a hierarchal navigation task with two commonly used touch interfaces for list browsing: pagination and expand-and-collapse interfaces. The results reveal that PinchList is significantly faster than other two interfaces in accessing items located in hierarchical list views. Finally, we demonstrate that PinchList enables a host of novel applications in list-based interaction?

Abstract: In this paper, we investigate the use of mobile technology in an underexplored context, the bed that couples share. Despite large amounts of research on the impact of pre-bedtime technology use on our sleep and mental state, scant research in the HCI field focuses on the physical bed as a negotiated site of technology use by couples. This paper explores (a) the meaning of the bed accessed by mobile technology and (b) the strategies of both individual and shared technology use in bed, in the context of couple's relationships. We investigate the effects of mobile technology to couples' bed-sharing practices through in-depth interviews (n = 12) and an online survey (n = 117). We report on creative and negotiated bodily practices of mobile technology use by couples in bed, and the perceived effects on couples' verbal and physical interaction and the intimacy of the bed.

Abstract: Ten years ago, Thaler and Sunstein introduced the notion of nudging to talk about how subtle changes in the 'choice architecture' can alter people's behaviors in predictable ways. This idea was eagerly adopted in HCI and applied in multiple contexts, including health, sustainability and privacy. Despite this, we still lack an understanding of how to design effective technology-mediated nudges. In this paper we present a systematic review of the use of nudging in HCI research with the goal of laying out the design space of technology-mediated nudging - the why (i.e., which cognitive biases do nudges combat) and the how (i.e., what exact mechanisms do nudges employ to incur behavior change). All in all, we found 23 distinct mechanisms of nudging, grouped in 6 categories, and leveraging 15 different cognitive biases. We present these as a framework for technology-mediated nudging, and discuss the factors shaping nudges' effectiveness and their ethical implications.

Abstract: Assistive technologies such as screen readers and text editors have been used in past to improve the accessibility and authoring of scientific and mathematical documents. However, most screens readers fail to narrate complex mathematical notations and expressions as they skip symbols and necessary information required for the accurate narration of mathematical content. This study aims at evaluating a new Accessible LaTeX Based Mathematical Document Authoring and Presentation (ALAP) tool, which assist people with visual impairments in reading and writing mathematical documents. ALAP includes features like, assistive debugging, Math Mode for reading and writing mathematical notations, and automatic generation of an accessible PDF document. These features aim to improve the LaTeX debugging experience and make it simple for blind users to author mathematical content by narrating it in natural language through the use of integrated text to speech (TTS) engine. We evaluated ALAP by conducting a study with 18 visually impaired LaTeX users. The results showed that users preferred ALAP over another comparable LaTeX based authoring tool and were relatively more comfortable in completing the tasks while using ALAP.

Abstract: Participatory performance provides methods for exploring social identities and situations in ways that can help people to imagine new ways of being. Digital technologies provide tools that can help people envision these possibilities. We explore this combination through a performance workshop process designed to help stroke survivors imagine new physical and social possibilities by enacting fantasies of "things they always wanted to do". This process uses performance methods combined with specially designed real-time movement visualisations to progressively build fantasy narratives that are enacted with and for other workshop participants. Qualitative evaluations suggest this process successfully stimulates participant's embodied imagination and generates a diverse range of fantasies. The interactive and communal aspects of the workshop process appear to be especially important in achieving these effects. This work highlights how the combination of performance methods and interactive tools can bring a rich, prospective and political understanding of people's lived experience to design.

Abstract: Virtual Reality nonfiction (VRNF) is an emerging form of immersive media experience created for consumption using panoramic "Virtual Reality" headsets. VRNF promises nonfiction content producers the potential to create new ways for audiences to experience "the real"; allowing viewers to transition from passive spectators to active participants. Our current project is exploring VRNF through a series of ethnographic and experimental studies. In order to document the content available, we embarked on an analysis of VR documentaries produced to date. In this paper, we present an analysis of a representative sample of 150 VRNF titles released between 2012-2018. We identify and quantify 64 characteristics of the medium over this period, discuss how producers are exploiting the affordances of VR, and shed light on new audience roles. Our findings provide insight into the current state of the art in VRNF and provide a digital resource for other researchers in this area.

Abstract: Effortless reading remains an issue for many Web users, despite a large number of readability guidelines available to designers. This paper presents a study of manual and automatic use of 39 readability guidelines in webpage evaluation. The study collected the ground-truth readability for a set of 50 webpages using eye-tracking with average and dyslexic readers (n = 79). It then matched the ground truth against human-based (n = 35) and automatic evaluations. The results validated 22 guidelines as being connected to readability. The comparison between human-based and automatic results also revealed a complex framework: algorithms were better or as good as human experts at evaluating webpages on specific guidelines - particularly those about low-level features of webpage legibility and text formatting. However, multiple guidelines still required a human judgment related to understanding and interpreting webpage content. These results contribute a guideline categorization laying the ground for future design evaluation methods.
Title: Trolled by the Trolley Problem: On What Matters for Ethical Decision Making in Automated Vehicles

Keywords: ethics, dilemma, trolley problem, automated vehicles

Abstract: Automated vehicles have to make decisions, such as driving maneuvers or rerouting, based on environment data and decision algorithms. There is a question whether ethical aspects should be considered in these algorithms. When all available decisions within a situation have fatal consequences, this leads to a dilemma. Contemporary discourse surrounding this issue is dominated by the trolley problem, a specific version of such a dilemma. Based on an outline of its origins, we discuss the trolley problem and its viability to help solve the questions regarding ethical decision making in automated vehicles. We show that the trolley problem serves several important functions but is an ill-suited benchmark for the success or failure of an automated algorithm. We argue that research and design should focus on avoiding trolley-like problems at all rather than trying to solve an unsolvable dilemma and discuss alternative approaches on how to feasibly address ethical issues in automated agents.

Abstract: Depression is an affective disorder with distinctive autobiographical memory impairments, including negative bias, overgeneralization and reduced positivity. Several clinical therapies address these impairments, and there is an opportunity to develop new supports for treatment by considering depression-associated memory impairments within design. We report on interviews with ten experts in treating depression, with expertise in both neuropsychology and cognitive behavioral therapies. The interviews explore approaches for addressing each of these memory impairments. We found consistent use of positive memories for treating all memory impairments, the challenge of direct retrieval, and the need to support the experience of positive memories. We aim to sensitize HCI researchers to the limitations of memory technologies, broaden their awareness of memory impairments beyond episodic memory recall, and inspire them to engage with this less explored design space. Our findings open up new design opportunities for memory technologies for depression, including positive memory banks for active encoding and selective retrieval, novel cues for supporting generative retrieval, and novel interfaces to strengthen the reliving of positive memories.

Abstract: Kinaesthetic creativity refers to the body's ability to generate alternate futures in activities such as role-playing in participatory design workshops. This has relevance not only to the design of methods for inspiring creativity but also to the design of systems that promote engaging experiences via bodily interaction. This paper probes this creative process by studying how dancers interact with technology to generate ideas. We developed a series of parameterized interactive visuals and asked dance practitioners to use them in generating movement materials. From our study, we define a taxonomy that comprises different relationships and movement responses dancers form with the visuals. Against this taxonomy, we describe six types of interaction patterns and demonstrate how dance creativity is driven by the ability to shift between these patterns. We then propose a set of interaction design qualities to support kinaesthetic creativity.

Abstract: Rankings distill a large number of factors into simple comparative models to facilitate complex decision making. Yet key questions remain in the design of mixed-initiative systems for ranking, in particular how best to collect users' preferences to produce high-quality rankings that users trust and employ in the real world. To address this challenge we evaluate the relative merits of three preference collection methods for ranking in a crowdsourced study. We find that with a categorical binning technique, users interact with a large amount of data quickly, organizing information using broad strokes. Alternative interaction modes using pairwise comparisons or sub-lists result in smaller, targeted input from users. We consider how well each interaction mode addresses design goals for interactive ranking systems. Our study indicates that the categorical approach provides the best value-added benefit to users, requiring minimal effort to create sufficient training data for the underlying ranking algorithm.

Abstract: Auditory alarms that repeatedly interrupt users until they react are common, especially in the context of alarms. However, when an alarm repeats, our brains habituate to it and perceive it less and less, with reductions in both perception and attention-shifting: a phenomenon known as the repetition-suppression effect (RS). To retain users' perception and attention, this paper proposes and tests the use of pitch- and intensity-modulated alarms. Its experimental findings suggest that the proposed modulated alarms can reduce RS, albeit in different patterns, depending on whether pitch or intensity is the focus of the modulation. Specifically, pitch-modulated alarms were found to reduce RS more when the number of repetitions was small, while intensity-modulated alarms reduced it more as the number of repetitions increased. Based on these results, we make several recommendations for the design of improved repeating alarms, based on which modulation approach should be adopted in various situations.
