Video conferencing systems have long facilitated work-related conversations among remote teams. However, social distancing due to the COVID-19 pandemic has forced colleagues to use video conferencing platforms to additionally fulfil social needs. Social talk, or informal talk, is an important workplace practice that is used to build and maintain bonds in everyday interactions among colleagues. Currently, there is a limited understanding of how video conferencing facilitates multiparty social interactions among colleagues. In our paper, we examine social talk practices during the COVID-19 pandemic among remote colleagues through semi-structured interviews. We uncovered three key themes in our interviews, discussing 1) the changing purposes and opportunities afforded by using video conferencing for social talk with colleagues, 2) how the nature of existing relationships and status of colleagues influences social conversations and 3) the challenges and changing conversational norms around politeness and etiquette when using video conferencing to hold social conversations. We discuss these results in relation to the impact that video conferencing tools have on remote social talk between colleagues and outline design and best practice considerations for multiparty videoconferencing social talk in the workplace.

This paper discusses an empirical study on the use and appropriation of a toolkit for cultural heritage professionals and other non-technical experts (such as exhibition designers) to envision, design and prototype tangible interactive installations for visitor engagement. The Toolkit is composed of an online editor (the software) and a set of interconnected physical components and devices (the hardware). The software enables creating, adapting, deploying and testing installations together with the digital content populating them, while the hardware underpins their hands-on interactivity. The Toolkit was evaluated holistically in workshops with participants from the cultural sector. We detail aspects of the Toolkit design and how it was used in practice by collaborating teams. We discuss results showing how the Toolkit supported three phases of development of tangible heritage installations: envisioning, designing, and rapid prototyping. This paper contributes new research in HCI on digital interaction in the heritage domain, and on designing and assessing tools supporting user-driven development of novel technologies.

Current teleguidance methods include verbal guidance and robotic teleoperation, which present tradeoffs between precision and latency versus flexibility and cost. We present a novel concept of "human teleoperation" which bridges the gap between these two methods. A prototype teleultrasound system was implemented which shows the concept’s efficacy. An expert remotely "teloperates" a person (the follower) wearing a mixed reality headset by controlling a virtual ultrasound probe projected into the person’s scene. The follower matches the pose and force of the virtual device with a real probe. The pose, force, video, ultrasound images, and 3-dimensional mesh of the scene are fed back to the expert. In this control framework, the input and the actuation are carried out by people, but with near robot-like latency and precision. This allows teleguidance that is more precise and fast than verbal guidance, yet more flexible and inexpensive than robotic teleoperation. The system was subjected to tests that show its effectiveness, including mean teleoperation latencies of 0.27 seconds and errors of 7 mm and 6◦ in pose tracking. The system was also tested with an expert ultrasonographer and four patients and was found to improve the precision and speed of two teleultrasound procedures.

ABSTRACT This special issue focuses on new perspectives of time within HCI research. We begin by explicating how HCI’s views of time have broadened over the years, going beyond the traditional subjective-objective dichotomy. We describe how the HCI community was originally anchored to clock time, but more recently the field has begun to incorporate the existential, social, and cultural dimensions of time. We introduce the papers in this special issue by contextualizing them according to different research areas. We conclude by identifying open issues and opportunities that should be explored in future HCI research and practice.

ABSTRACT Wearable technologies are increasing both in number and variety enabling new ways for collecting personal data, as well as novel interaction modalities. Even though the Human-Computer Interaction (HCI) community has widely explored the potential applications of wearables, its theoretical contribution on this research field has been far from impressive. Most scholars and designers seem to rely on a series of dominant assumptions that look at wearables “from the outside” by focusing on their “external properties.” When these assumptions are fully embraced at design-time, however, they may cloud opportunities for designing for the “internal aspects” of our everyday experience. In this article, I propose a theory that looks at wearables “from the inside,”giving a theoretical backdrop to all those wearable designs that pay attention to the internal aspects of interaction. By adopting a postphenomenological approach, I conceptualize wearable devices as “extensions” of our intentionality and introduce the “extension relation” to explain how wearables may alter how we relate to the world. In doing so, I propose a series of design considerations that aim to trace future research lines for all those wearables that are currently designed from an “externalistic” perspective.

ABSTRACT HCI has recently increased its interest in the domains of museums and gifting. The former is often oriented primarily towards the past, while the latter is often oriented towards the future, in terms of anticipating the receiver’s reactions. Our article provides a sustained and well-evidenced new theoretical framework on the role of time-orientation on the design of forward-oriented (gifting) experiences in past-oriented (museum) settings. This Temporal Experience Design Framework develops from the analysis of two such studies, one smartphone app and one VR experience using passive haptics. Both interventions prompted the user to reflect on the past while planning a gift or donation for future consumption. We apply a novel combination of analyses to both projects using the lenses of conversational storytelling, performance, and human geography. Our analyses reveal the power of orienting users towards the past and the future – simultaneously – to enhance the present moment of a performative engagement. Our aim is to provide a conceptual framework that can help design researchers to identify, name, and understand how time-orientation can be used to enhance user and visitor experience. We also extrapolate design guidelines that we expect may be fruitful outside these contexts.

ABSTRACT We zone out roughly 20-40% of the time during reading – a rate that is concerning given the negative relationship between mind-wandering and comprehension. We tested if Eye-Mind Reader – an intelligent interface that targeted mind-wandering as it occurred – could mitigate its negative impact on reading comprehension. When an eye-gaze-based classifier indicated that a reader was mind-wandering, those in a MW-Intervention condition were asked to self-explain the concept they were reading about. If the self-explanation quality was deemed subpar by an automated scoring mechanism, readers were asked to re-read parts of the text in order to correct their comprehension deficits and improve their self-explanation. Each participant in the MW-Intervention condition was paired with a Yoked-Control counterpart who received the exact same interventions regardless of whether they were mind-wandering. Results indicate that re-reading improved self-explanation quality for the MW-Intervention group, but not the control group. The two conditions performed equally well on textbase (i.e. fact-based) and inference-level comprehension questions immediately after reading. However, after a week-long delay, the MW-Intervention condition significantly outperformed the yoked-control condition on both comprehension assessments (ds = .352 and .307). Our findings suggest that real-time interventions during critical periods of mind-wandering can promote long-term retention and comprehension.
