Deictic gestures are gestures we make during communication to point at objects or persons. Indicative acts of directing-to guide the addressee to an object, while placing-for acts place an object for the addressee’s attention. Commonly used presentation software tools, such as PowerPoint and Keynote, offer ample support for placing-for gestures, e.g. slide transitions, progressive disclosure of list items and animations. Such presentation tools, however, do not generally offer adequate support for the directing-to indicative act (i.e. pointing gestures). In this paper we argue the value of presenting deictic gestures to a remote audience. Our research approach is threefold: identify indicative acts that are naturally produced by presenters; design tangible gestures for multi-touch surfaces that replicate the intent of those indicative acts; and design a set of graphical effects for remote viewing that best represent these indicative acts for the audience.

This research report contains the findings of an international study consisting of three online ‘living’ surveys. The surveys focused on how the COVID-19 pandemic has impacted sign language interpreters’ working practices, how this was experienced by them, and how digital disruption caused by the pandemic is impacting and innovating the sign language interpreting profession. The study was carried out between April 2020 and July 2020; the largest contingent of respondents over all three surveys were from the U.S., followed by the UK, the Netherlands, Germany, Finland and Belgium. Respondents commented that the crisis will probably accelerate the need for remote interpreting training in interpreter training programs. Another resurfacing issue was the perceived need for sign language interpreting students to have face-to-face practice and live mentoring. Respondents commented on what benefits they thought remote interpreting might bring to the table, both for themselves and for deaf people. In general, the most significant benefits that were mentioned were flexibility and the possibility to improve efficiency and availability of sign language interpreting services. Notwithstanding these benefits, a significant number of respondents claimed that remote interpreting is more stressful than face-to-face interpreting and requires a heavier cognitive load.

Remote maintenance activities in ITER will be performed by a unique set of hardware systems, supported by an extensive software kit. A layer of middleware will manage and control a complex set of interconnections between teams of operators, hardware devices in various operating theatres, and databases managing tool and task logistics. The middleware is driven by constraints on the amounts and timing of data like real-time control loops, camera images, and database access. The Remote Handling Study Centre (RHSC), located at FOM Institute DIFFER, has a 4-operator work cell in an ITER-relevant RH control room setup which connects to a virtual hot cell back-end. The Centre is developing and testing flexible integration of the Control Room components, resulting in proof-of-concept tests of this middleware layer. SW components studied include generic human-machine interface software, a prototype of an RH operations management system, and a distributed virtual reality system supporting multi-screen, multi-actor, and multiple independent views. Real-time rigid body dynamics and contact interaction simulation software supports the simulation of structural deformation, "augmented reality" operations and operator training. The paper presents generic requirements and conceptual design of middleware components and Operations Management Systems in the context of an RH Control Room work cell. The simulation software is analyzed for real-time performance and it is argued that it is critical for middleware to have complete control over the physical network to be able to guarantee bandwidth and latency to the components.

In this paper we present a method to detect the three dimensional position and orientation of a Wii Remote with one or more emissive spheres attached to it, providing an input device that has six degrees of freedom. Unlike other systems, our system can focus in different directions surrounding the user, with a high precision, and at a low cost. We describe the way object-, motion- and orientation tracking is done, as well as the applicability of the final product. We further describe how to improve the noisy data that is retrieved from the sensors of the Wii Remote, how to smooth detected positions, and how to extrapolate position and orientation.

Background: Remote coaching might be suited for providing information and support to patients with coronary artery disease (CAD) in the vulnerable phase between hospital discharge and the start of cardiac rehabilitation (CR).Objective: The goal of the research was to explore and summarize information and support needs of patients with CAD and develop an early remote coaching program providing tailored information and support.Methods: We used the intervention mapping approach to develop a remote coaching program. Three steps were completed in this study: (1) identification of information and support needs in patients with CAD, using an exploratory literature study and semistructured interviews, (2) definition of program objectives, and (3) selection of theory-based methods and practical intervention strategies.Results: Our exploratory literature study (n=38) and semistructured interviews (n=17) identified that after hospital discharge, patients with CAD report a need for tailored information and support about CAD itself and the specific treatment procedures, medication and side effects, physical activity, and psychological distress. Based on the preceding steps, we defined the following program objectives: (1) patients gain knowledge on how CAD and revascularization affect their bodies and health, (2) patients gain knowledge about medication and side effects and adhere to their treatment plan, (3) patients know which daily physical activities they can and can’t do safely after hospital discharge and are physically active, and (4) patients know the psychosocial consequences of CAD and know how to discriminate between harmful and harmless body signals. Based on the preceding steps, a remote coaching program was developed with the theory of health behavior change as a theoretical framework with behavioral counseling and video modeling as practical strategies for the program.Conclusions: This study shows that after (acute) cardiac hospitalization, patients are in need of information and support about CAD and revascularization, medication and side effects, physical activity, and psychological distress. In this study, we present the design of an early remote coaching program based on the needs of patients with CAD. The development of this program constitutes a step in the process of bridging the gap from hospital discharge to start of CR.

The installation of facilities replicating the realworld condition is often required for carrying out meaningful tests on new devices and for collecting data with the aim to create realistic device model. However, these facilities require huge investments, as well as areas where they can be properly installed. In this paper, we present a test infrastructure exploiting the concept of Remote Power Hardware-In-the-Loop (RPHIL), applied for characterizing the performances of a 8kW Proton Exchange Membrane (PEM) electrolyser installed at the Hanze University of Applied Sciences in Groningen (The Netherlands). The electrolyser is subjected to different test conditions imposed both locally and remotely. The results show that this measurement procedure is effective and can open new perspectives in the way to share and exploit the existing research infrastructure in Europe

This article examines the impact of the COVID-19 pandemic on the sign language interpreting profession drawing on data from a fourth and final survey conducted in June 2021 as part of a series of online “living surveys” during the pandemic. The survey, featuring 331 respondents, highlights significant changes in the occupational conditions and practices of sign language interpreters due to the sudden shift towards remote video-mediated interpreting. The findings reveal a range of challenges faced by interpreters, including the complexities of audience design, lack of backchanneling from deaf consumers, the need for heightened self-monitoring, nuanced conversation management, and team work. Moreover, the study highlights the physical and mental health concerns that have emerged among interpreters as a result of the shift in working conditions, and a need for interpreters to acquire new skills such as coping with the multimodal nature of online interpreting. While the blend of remote, hybrid, and on-site work has introduced certain advantages, it also poses new challenges encompassing workload management, online etiquette, and occupational health concerns. The survey’s findings underscore the resilience and adaptability of SLIs in navigating the shift to remote interpreting, suggesting a lasting transformation in the profession with implications for future practice, training, and research in the post-pandemic era.

At present, COVID-19 has caused a possible paradigm shift in education, especially in education delivery for higher educational and learning institutions. To align with the national government and relevant national/international authorities’ policies and to avoid the spread of the virus, educational institutions in many nations have decided to temporarily suspend the traditional classroom-based education and replace it with online-based education. This studyaims at exploring the impact of COVID-19 pandemic and obligatory remote working on work-life balance, mental health and productivity of faculty members working in higher education institutions (HEI). The study is exploratory and uses a qualitative approach using an online survey strategy to include voices of faculty members from different countries. While the results of this study indicate both positive and negative effects of obligatory remote working on faculty members’ work-life balance, well-being and productivity at the same time our findings indicate that university administration must pay heed to address concerns presented in the results.

Background: The COVID-19 pandemic taught us how to rethink care delivery. It catalyzed creative solutions to amplify the potential of personnel and facilities. This paper presents and evaluates a promptly introduced triaging solution that evolved into a tool to tackle the ever-growing waiting lists at an academic ophthalmology department, the TeleTriageTeam (TTT). A team of undergraduate optometry students, tutor optometrists, and ophthalmologists collaborate to maintain continuity of eye care. In this ongoing project, we combine innovative interprofessional task allocation, teaching, and remote care delivery. Objective: In this paper, we described a novel approach, the TTT; reported its clinical effectiveness and impact on waiting lists; and discussed its transformation to a sustainable method for delivering remote eye care. Methods: Real-world clinical data of all patients assessed by the TTT between April 16, 2020, and December 31, 2021, are covered in this paper. Business data on waiting lists and patient portal access were collected from the capacity management team and IT department of our hospital. Interim analyses were performed at different time points during the project, and this study presents a synthesis of these analyses. Results: A total of 3658 cases were assessed by the TTT. For approximately half (1789/3658, 48.91%) of the assessed cases, an alternative to a conventional face-to-face consultation was found. The waiting lists that had built up during the first months of the pandemic diminished and have been stable since the end of 2020, even during periods of imposed lockdown restrictions and reduced capacity. Patient portal access decreased with age, and patients who were invited to perform a remote, web-based eye test at home were on average younger than patients who were not invited. Conclusions: Our promptly introduced approach to remotely review cases and prioritize urgency has been successful in maintaining continuity of care and education throughout the pandemic and has evolved into a telemedicine service that is of great interest for future purposes, especially in the routine follow-up of patients with chronic diseases. TTT appears to be a potentially preferred practice in other clinics and medical specialties. The paradox is that judicious clinical decision-making based on remotely collected data is possible, only if we as caregivers are willing to change our routines and cognitions regarding face-to-face care delivery.

The airport of Mexico City has been declared saturated for most of the day. For that reason, the Mexican government announced a couple of years ago the construction of a completely new one which is supposed to be operative in 2020 in its first phase. However, the technical issues and the economic downturn in the country jeopardise the project; for that reason, it is important to have alternatives that allow investing in a progressive fashion so that the investments are not lost or end up in useless infrastructure like the ones that have taken place in other parts of the world. The current work presents a simulation-based study of the alternative of using one of the runways of the new airport in a remote fashion in case the original project is delayed or even cancelled. The results indicate that the proposed infrastructure alleviates the congestion problem in the current airport, and at the same time allows the traffic growth with performance indicators similar to airports that have remote runways as in the case of Schiphol in The Netherlands.
