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.
Alcohol use disorder (AUD) is a major problem. In the USA alone there are 15 million people with an AUD and more than 950,000 Dutch people drink excessively. Worldwide, 3-8% of all deaths and 5% of all illnesses and injuries are attributable to AUD. Care faces challenges. For example, more than half of AUD patients relapse within a year of treatment. A solution for this is the use of Cue-Exposure-Therapy (CET). Clients are exposed to triggers through objects, people and environments that arouse craving. Virtual Reality (VRET) is used to experience these triggers in a realistic, safe, and personalized way. In this way, coping skills are trained to counteract alcohol cravings. The effectiveness of VRET has been (clinically) proven. However, the advent of AR technologies raises the question of exploring possibilities of Augmented-Reality-Exposure-Therapy (ARET). ARET enjoys the same benefits as VRET (such as a realistic safe experience). But because AR integrates virtual components into the real environment, with the body visible, it presumably evokes a different type of experience. This may increase the ecological validity of CET in treatment. In addition, ARET is cheaper to develop (fewer virtual elements) and clients/clinics have easier access to AR (via smartphone/tablet). In addition, new AR glasses are being developed, which solve disadvantages such as a smartphone screen that is too small. Despite the demand from practitioners, ARET has never been developed and researched around addiction. In this project, the first ARET prototype is developed around AUD in the treatment of alcohol addiction. The prototype is being developed based on Volumetric-Captured-Digital-Humans and made accessible for AR glasses, tablets and smartphones. The prototype will be based on RECOVRY, a VRET around AUD developed by the consortium. A prototype test among (ex)AUD clients will provide insight into needs and points for improvement from patient and care provider and into the effect of ARET compared to VRET.
In the last decade, the automotive industry has seen significant advancements in technology (Advanced Driver Assistance Systems (ADAS) and autonomous vehicles) that presents the opportunity to improve traffic safety, efficiency, and comfort. However, the lack of drivers’ knowledge (such as risks, benefits, capabilities, limitations, and components) and confusion (i.e., multiple systems that have similar but not identical functions with different names) concerning the vehicle technology still prevails and thus, limiting the safety potential. The usual sources (such as the owner’s manual, instructions from a sales representative, online forums, and post-purchase training) do not provide adequate and sustainable knowledge to drivers concerning ADAS. Additionally, existing driving training and examinations focus mainly on unassisted driving and are practically unchanged for 30 years. Therefore, where and how drivers should obtain the necessary skills and knowledge for safely and effectively using ADAS? The proposed KIEM project AMIGO aims to create a training framework for learner drivers by combining classroom, online/virtual, and on-the-road training modules for imparting adequate knowledge and skills (such as risk assessment, handling in safety-critical and take-over transitions, and self-evaluation). AMIGO will also develop an assessment procedure to evaluate the impact of ADAS training on drivers’ skills and knowledge by defining key performance indicators (KPIs) using in-vehicle data, eye-tracking data, and subjective measures. For practical reasons, AMIGO will focus on either lane-keeping assistance (LKA) or adaptive cruise control (ACC) for framework development and testing, depending on the system availability. The insights obtained from this project will serve as a foundation for a subsequent research project, which will expand the AMIGO framework to other ADAS systems (e.g., mandatory ADAS systems in new cars from 2020 onwards) and specific driver target groups, such as the elderly and novice.
Closer Connections aims to build a coherent, cross-academy, virtual- and augmented reality strategy to contribute to the European agenda: “a Europe fit for the digital age”. Closer Connections enables the SPRONG group DIGIREAL to strengthen its visibility and reputation on a European level to build strong alliances with European VR/AR coalitions and associations and apply for EU grants. In this project, a strategic paper on market assessment is developed to determine our position within this European agenda. This is followed by a roadmap for the future utilisation of our rare assets (XR-stage, photogrammetry, etc.), and raise awareness of the unique combination of excellent facilities, creative staff and talented students.
