Remote UX Research in Unpredictable Times: Takeaways from Early Pandemic Practices
Copyright © 2023–2024, User Experience Professionals Association and the authors The recent global pandemic had shocking impacts on societies and economies worldwide by bringing complexity, ambiguity, and uncertainty for extended periods. UX researchers, faced with numerous challenges, were compelled to adapt to emergent conditions through remote research methods.
Investigating how some members of the UX research community adapted to the emergency offers valuable insights into how they responded to uncertainty and showed resilience. Therefore, we studied the early practices of UX managers and researchers in Turkey during the first 6 months of the global pandemic under lockdown conditions. Our goal was to understand how UX research and design teams responded to uncertainty by customizing their methods.
We focused on seven firms as different cases to conduct semi-structured interviews with seven managers and 13 UX researchers. The results demonstrate that the adaptable nature of UX research allowed them to quickly respond to these emerging conditions.
In the early period of the pandemic, our study participants—UX managers, designers, and researchers—experienced the advantages and challenges of remote UX research necessitated by the lockdown. These included issues related to participant recruitment, work performance, readiness, and methodological concerns. Based on our findings, we make recommendations for UX researchers to conduct moderated and unmoderated remote research while maintaining inclusiveness and rigor.TÜBİTAK (The Scientific and Technological Research Council of Turkey).

Serious Games and Mixed Reality Applications for Healthcare
Virtual reality (VR) and augmented reality (AR) have long histories in the healthcare sector, offering the opportunity to develop a wide range of tools and applications aimed at improving the quality of care and efficiency of services for professionals and patients alike. The best-known examples of VR–AR applications in the healthcare domain include surgical planning and medical training by means of simulation technologies. Techniques used in surgical simulation have also been applied to cognitive and motor rehabilitation, pain management, and patient and professional education. Serious games are ones in which the main goal is not entertainment, but a crucial purpose, ranging from the acquisition of knowledge to interactive training.These games are attracting growing attention in healthcare because of their several benefits: motivation, interactivity, adaptation to user competence level, flexibility in time, repeatability, and continuous feedback. Recently, healthcare has also become one of the biggest adopters of mixed reality (MR), which merges real and virtual content to generate novel environments, where physical and digital objects not only coexist, but are also capable of interacting with each other in real time, encompassing both VR and AR applications.This Special Issue aims to gather and publish original scientific contributions exploring opportunities and addressing challenges in both the theoretical and applied aspects of VR–AR and MR applications in healthcare
Enhanced Virtuality: Increasing the Usability and Productivity of Virtual Environments
Mit stetig steigender Bildschirmauflösung, genauerem Tracking und fallenden Preisen stehen Virtual Reality (VR) Systeme kurz davor sich erfolgreich am Markt zu etablieren. Verschiedene Werkzeuge helfen Entwicklern bei der Erstellung komplexer Interaktionen mit mehreren Benutzern innerhalb adaptiver virtueller Umgebungen. Allerdings entstehen mit der Verbreitung der VR-Systeme auch zusätzliche Herausforderungen: Diverse Eingabegeräte mit ungewohnten Formen und Tastenlayouts verhindern eine intuitive Interaktion. Darüber hinaus zwingt der eingeschränkte Funktionsumfang bestehender Software die Nutzer dazu, auf herkömmliche PC- oder Touch-basierte Systeme zurückzugreifen. Außerdem birgt die Zusammenarbeit mit anderen Anwendern am gleichen Standort Herausforderungen hinsichtlich der Kalibrierung unterschiedlicher Trackingsysteme und der Kollisionsvermeidung. Beim entfernten Zusammenarbeiten wird die Interaktion durch Latenzzeiten und Verbindungsverluste zusätzlich beeinflusst. Schließlich haben die Benutzer unterschiedliche Anforderungen an die Visualisierung von Inhalten, z.B. Größe, Ausrichtung, Farbe oder Kontrast, innerhalb der virtuellen Welten. Eine strikte Nachbildung von realen Umgebungen in VR verschenkt Potential und wird es nicht ermöglichen, die individuellen Bedürfnisse der Benutzer zu berücksichtigen.
Um diese Probleme anzugehen, werden in der vorliegenden Arbeit Lösungen in den Bereichen Eingabe, Zusammenarbeit und Erweiterung von virtuellen Welten und Benutzern vorgestellt, die darauf abzielen, die Benutzerfreundlichkeit und Produktivität von VR zu erhöhen. Zunächst werden PC-basierte Hardware und Software in die virtuelle Welt übertragen, um die Vertrautheit und den Funktionsumfang bestehender Anwendungen in VR zu erhalten. Virtuelle Stellvertreter von physischen Geräten, z.B. Tastatur und Tablet, und ein VR-Modus für Anwendungen ermöglichen es dem Benutzer reale Fähigkeiten in die virtuelle Welt zu übertragen. Des Weiteren wird ein Algorithmus vorgestellt, der die Kalibrierung mehrerer ko-lokaler VR-Geräte mit hoher Genauigkeit und geringen Hardwareanforderungen und geringem Aufwand ermöglicht. Da VR-Headsets die reale Umgebung der Benutzer ausblenden, wird die Relevanz einer Ganzkörper-Avatar-Visualisierung für die Kollisionsvermeidung und das entfernte Zusammenarbeiten nachgewiesen. Darüber hinaus werden personalisierte räumliche oder zeitliche Modifikationen vorgestellt, die es erlauben, die Benutzerfreundlichkeit, Arbeitsleistung und soziale Präsenz von Benutzern zu erhöhen. Diskrepanzen zwischen den virtuellen Welten, die durch persönliche Anpassungen entstehen, werden durch Methoden der Avatar-Umlenkung (engl. redirection) kompensiert. Abschließend werden einige der Methoden und Erkenntnisse in eine beispielhafte Anwendung integriert, um deren praktische Anwendbarkeit zu verdeutlichen.
Die vorliegende Arbeit zeigt, dass virtuelle Umgebungen auf realen Fähigkeiten und Erfahrungen aufbauen können, um eine vertraute und einfache Interaktion und Zusammenarbeit von Benutzern zu gewährleisten. Darüber hinaus ermöglichen individuelle Erweiterungen des virtuellen Inhalts und der Avatare Einschränkungen der realen Welt zu überwinden und das Erlebnis von VR-Umgebungen zu steigern
Exploring and Designing Embodied Mindfulness-based Interactive Technologies For Mental Wellbeing
Mindfulness practices have become increasingly popular due to their significant benefits for mental wellbeing. However, the required skills to sustain and regulate attention are challenging to develop. Both the benefits and the challenges of mindfulness training have attracted a growing Human-Computer Interaction (HCI) interest in designing interactive technologies for mindfulness. Most mindfulness-based technologies employ metaphorical mappings of mindfulness states to support awareness of such states and facilitate attention regulation, although the rationale for such mappings is seldom articulated. This thesis addresses this shortcoming, drawing on first-person experiences and embodied metaphors of mindfulness practices to design novel multi-sensory technologies for mental wellbeing. This work concentrates on focused attention mindfulness (FAM) practices which involve sustaining selective attention moment by moment on a chosen object, and are considered the most widely accessible among novices. In particular, the research presented in this thesis is structured around two distinct FAM practices, in 6 different but interrelated studies. On the one hand, mandala colouring illustrates a nonstatic FAM practice with an external object of attention. On the other hand, sitting meditation represents a static FAM practice with an internal object of attention. The first and second study investigate in-depth mandala colouring, respectively, by interviewing 21 people who regularly engage with this practice and through an autoethnographic and heuristic evaluation of the 14 top-ranked mandala colouring apps. Findings informed the development of Anima, a peripheral colour palette materialising EEG-based mindfulness states onto colours for mandala colouring. In the third study, Anima’s design solutions were evaluated with 12 experienced participants. The fourth study follows a research-through design and material speculation approach to understand the role of body during meditation with 24 experts. This is extended in the fifth study, in which the 16 most popular meditation apps are evaluated through auto-ethnography. An identified opportunity of designing for the physical sensations that arise during meditation was considered through the design of the WarmMind, that provide warmth patterns on the upper body. The WarmMind prototype was evaluated in the fifth study, through a user study with 10 participants experiencing thermal metaphors for mapping meditation states on the upper-body. Besides the technological design contributions of Anima and WarmMind, the contributions of this thesis include the concepts of intricate confines to scaffold mindful movement to support non-static FAM practices with an external object of attention, and interoceptive interaction to facilitate focusing inwards during meditation to support static FAM practices with an internal object of attention; as well as a framework built on embodied metaphor theories to designing meditation technologies. Collectively, these studies highlight the value of the human body in mindfulness-based technologies in HCI, as well as theoretical and methodological contributions to designing around mindfulness for mental wellbeing in HCI

The body beyond movement: (Missed) opportunities to engage with contemporary dance in HCI
This paper argues that a significant paradigm change in contemporary dance can offer further opportunities for HCI researchers interested in embodied interaction and interactive system design. Based on the analysis of 42 HCI papers in our data set, resulting from searches in two computing research libraries, we suggest seven thematic categories that reflect how HCI researchers have been engaging with contemporary dance. Moreover, we propose a standardized usage of contemporary dance terminology in HCI literature, and discuss the current state of engagement with publications from the field of performance theory. We identify three opportunities for HCI, which can arise through further engagement with the knowledge produced in contemporary dance and performance: to engage with the field of embodied interaction from the perspective of performance research and theory; to employ contemporary dance methods and practices in HCI research; and to integrate contemporary dance choreographers and performers as researchers in interdisciplinary projects
