In the Dutch armed forces clothing sizes are determined using 3D body scans. To evaluate if the predicted size based on the scan analysis matches the best fit, 35 male soldiers fitted a combat jacket and combat pants. It was shown that the predicted jacket size was slightly too large. Therefore, an adjustment was proposed. The predicted and preferred pant size matched rather well. We further investigated discrepancies between predicted and preferred sizes using virtual fitting analysis. Colour maps showing the difference between garment and body circumference illustrated that some soldiers selected a garment size that was obviously too small or too large. In order to minimize the effect of personal preference and maximize standardize ease, we recommend to maintain the current size prediction (with minor corrections for jackets) and use virtual fitting selectively as a control measure.

Due to the rise of knowledge work since the 1980s, high job autonomy and high task variety have become common job characteristics. Knowledge workers increasingly work across multiple locations, using advanced information and communication technologies; a trend that is expected to accelerate in the post-COVID-19 world of work. As these developments fundamentally change the use of office work environments, organizations and workplace professionals have been searching for new ways to facilitate the workforce more effectively and efficiently. In the past two decades, more and more of them seem to have found the ultimate solution in activity-based working (ABW). According to this concept, workers share a variety of non-assigned work settings, enabling them to use different work settings in accordance with their varying tasks. Yet, outcomes of AWB environments generally fall short of expectations. Remarkably, while sharing the same ABW environment, some workers seem to experience fit while others do not.Optimization of perceived fit with ABW environments is important fororganizations, since it is linked to various work outcomes. Currently, this isparticularly relevant in the context of expected post-COVID-19 changes in workpractices. To find clues for optimization of ABW practice, the current PhD research project was designed to examine how workers’ jobs, tasks, behaviors, psychological needs, and demographic characteristics may be related to their perceived fit. Two survey-based studies revealed relevant workers’ attributes, which were further examined in experience-sampling field studies and a virtual reality experiment. From the findings, a clear profile arises of workers who best fit with ABW environments, i.e.: high task variety, job autonomy, external and internal mobility, social interaction, and need for relatedness; low need for privacy; few highcomplexity tasks, many non-individual tasks; appropriately using open and closed work settings; frequently switching between work settings; relatively young age.

This paper describes a project to explore the possibilities of virtual worlds in educating Green IT. In the project a virtual world has been created with various assignments which are meant to create awareness on sustainability aspects of IT. The world (and the assignments) will be incorporated in a course for first-year IT students. In order to measure the effects of the course, a questionnaire has been developed which can be used before and after the course to measure the attitude towards green IT.

Designers are increasingly collaborating with various stakeholders to address complex societal challenges. These challenges often require a codesign approach, where differ-ent actors with diverse perspectives and experiences unite to explore innovative ave-nues for change. Such collaboration requires empathy between the actors to under-stand each other’s perspective better in their interactions. This paper aims to assist so-cial designers in orchestrating such empathic codesign processes by introducing an Em-pathic Journey framework. This conceptual and practical framework is based on em-pathic design theory and three design cases which used Virtual Reality for perspective exchange between actors. The framework addresses the importance of integrating an emotional spark through immersion and the necessity of embedding immersive experiences in a larger journey.

Virtual care centres (VCCs) are novel wards of hospitals and facilitate the provision of remote monitoring and home-based patient care by virtual care nurses. Whereas since the COVID-19 pandemic VCCs have rapidly emerged, there is a lack of insight in virtual care nurses’ work and the associated work load. Therefore, the aim of this study was to identify the nursing activities performed in Virtual Care Centers (VCCs) and assess nurses’ perceived workload associated with these activities. A multicentre descriptive, observational cross-sectional study was performed.

Collaborative Online International Learning (COIL) is often framed as an example of a broader practice known as Virtual Exchange (VE). The term Virtual Exchange has increasingly been used as an attempt to unify a fragmented field of Higher Education practice and is often used interchangeably with the term COIL. However, the design of COIL, with its strong focus on collaborative and intercultural learning, is often very different to other VE initiatives. Labelling all VE initiatives, including COIL, generally as VE, can lead to both educators and researchers having difficulty identifying and distinguishing COIL. Therefore, the purpose of this paper is to provide a critical review of VE and define COIL and its key characteristics. This article also describes how theory can inform practice and explains why continued interchangeable use of the term COIL with the umbrella term Virtual Exchange is unhelpful for future research and practice.

Abstract Background Visuospatial neglect (VSN) is a cognitive disorder after stroke in which patients fail to consciously process and interact with contralesional stimuli. Visual Scanning Training (VST) is the recommended treatment in clinical guidelines. At the moment, several mixed reality versions of Visual Scanning Training (VST) are being developed. The aim of this study was to explore the opinions of end-users (i.e., therapists) on the use of Virtual Reality (VR) and Augmented Reality (AR) in VSN treatment. Methods Therapists played one VR and two AR Serious Games, and subsequently flled out a questionnaire on User Experience, Usability, and Implementation. Results Sixteen therapists (psychologists, occupational, speech, and physiotherapists) played the games, thirteen of them evaluated the games. Therapists saw great potential in all three games, yet there was room for improvement on the level of usability, especially for tailoring the games to the patient’s needs. Therapists’ opinions were comparable between VR and AR Serious Games. For implementation, therapists stressed the urgency of clear guidelines and instructions. Discussion Even though VR/AR technology is promising for VSN treatment, there is no one-size-fts-all applicability. It may thus be crucial to move towards a plethora of training environments rather than a single standardized mixed reality neglect treatment. Conclusion As therapists see the potential value of mixed reality, it remains important to investigate the efcacy of AR and VR training tools.

With a growing interest in immersive technologies to elevate digital spectating experiences, Virtual Reality (VR) is viewed by many academics and industry actors as the future of esport spectatorship. The majority of the esport fans are the same group that show interest in immersive technologies as VR. This group is, therefore, expected to accept the technology and adopt it in their spectating experience. However, given the fact that this target group is mostly used to utilize interactive VR for gaming purposes, it is not clear how they would experience a passive non-interactive VR experience, and to what extent the technology could contribute to enhancing their viewing experience. This study compared two versions of the same summary recording of the livestream of an esport competition: a 2D version and a VR version: 92 participants watched the esport competition either on a 2D screen or in VR, then they had to answer questions regarding their experience. Compared to 2D, the VR experience scored higher on immersion, presence, social presence, emotional contagion, and enjoyment. This paper confirms the potential of VR to efficiently enhance the digital spectating experiences of esports, while highlighting the need for more research in how to produce the content to best fit VR and increase VR adoption intention.

Chronic itching is a serious and uncomfortable condition. The scratch response might result in a vicious cycle of alternating itching and scratching. To develop psychological interventions for people suffering from chronic itching and to break the vicious itch-scratching-itch cycle, it is important to elucidate which environmental factors trigger itch sensations. Virtual reality (VR) techniques provide a useful tool to examine specific content characteristics in a three-dimensional (3D VR) environment and their influences on itch sensations and scratching behaviour. This article describes two experiments in which we focused on the effects of environmental information on itching and scratching behaviour. Additionally, in the second experiment, we examined the influence of having a chronic skin condition on sensitivity to itch induction. We found evidence for the importance of the content of audio–visual materials for the effectiveness in inducing feelings of itch in the observers. In both experiments, we observed significantly higher levels of perceived itch in the itch-inducing conditions than in the control condition. Moreover, the results showed that elevated levels of perceived itch were associated with an increase in scratching behaviours, which was especially salient in the contagious itch condition, in which perceived itch was accompanied by a significant increase in the number of scratches. Experiment 2 additionally showed increased perceived itch levels in participants who reported having a chronic skin condition, reflecting higher sensitivity to itch-inducing audio–visual stimuli in this group than in participants without a chronic skin condition. Based on the results we concluded that directing attention towards itch- or scratch aspects of related information in the environment and to the consequences for one’s own skin are effective tools to induce itch sensations and scratching behaviour. This knowledge provides tools for developing novel strategies in advising and treating people suffering from chronic itching and breaking the vicious itch-scratching-itch cycle.

Activity-based work environments are widely adopted; however, research shows mixed findings regarding privacy issues, satisfaction with the work environment, and task performance. To further our understanding, two complementary studies drawing on Person-Environment fit theory were conducted: (1) A field study using experience sampling, and (2) A lab study in a virtual reality studio. The results from both studies confirm that perceived fit is a function of activity, work setting, and personal need for privacy, with indirect effects on satisfaction with the work environment (Studies 1 and 2) and task performance (Study 2). Across both studies, a misfit was perceived particularly among workers high in personal need for privacy when performing high-complexity tasks in an open office work setting. Hence, we recommend that organizations facilitate and stimulate their workers to create better fits between activities, work settings, and personal characteristics.
