Nature in cities serves a multitude of purposes, one of which is that it provides citizens opportunities to recover from stressful daily urban life. Such stress recovering effects of nature can be experienced through urban green, which in urban planning and design contexts can be divided into large natural areas - urban green space - and small scale elements in urban streets: the urban greenscape. The current study aims at finding the extent to which various small scale natural elements in residential streets and their possible configurations influence citizens' preferences for those streets. The research was conducted through an online survey in four cities in the Netherlands (n = 4,956). It used stated choice methods in a virtual environment street design. The method yielded high quality data, indicating that the use of virtual environments and imagery is suitable for stated choice research in the built environment. The results show that especially trees very strongly influence preference, indicating they deserve more attention and space in cities. Grass, which is typically favored by local governments, and vertical green have the smallest effects in residential streets. Furthermore, the concept of greenscape intensity is introduced as the intensities of both the element and the configuration were found to be highly relevant. The results clearly show that the higher either of these intensities, the more likely a respondent will prefer the greenscape design. Furthermore, low intensity on the one can be compensated by high intensity on the other. With these results, urban design professionals and local governments can better trade-off the different aspects of costs versus positive effects of urban greenscape designs.

Sportverenigingen in Nederland dragen bij aan een gezonde leefstijl, sociale cohesie en inclusieve sportdeelname. Ondanks dat de sportparticipatie toeneemt, hebben de clubs het moeilijk om hun ledental op peil te houden. Diverse ontwikkelingen spelen daarbij een rol. De focus van het onderzoek in dit proefschrift richt zich op twee maatschappelijke ontwikkelingen, ‘individualisering’ en ‘digitalisering’. In zeven studies wordt antwoord gegeven op twee onderzoeksvragen: 1) hoe het clubgevoel van leden van sportvereniging kan worden geconceptualiseerd in termen van definitie, voorspellers en opbrengsten en 2) hoe sociaalnetwerksites van sportverenigingen kunnen bijdragen het ontwikkelen van het clubgevoel van leden? Die studies vormen samen een multimethode onderzoek. Resultaten laten zien dat clubgevoel verwijst naar de gevoelsband van leden met hun club op basis van participatie, relevantie en de sociale wereld van de club. Clubgevoel hangt samen met bindingsaspecten zoals de intentie om je in te zetten voor de club en te blijven. Sociaalnetwerksites van sportverenigingen kunnen helpen om dit clubgevoel te ontwikkelen, bij voorkeur door de kanalen in te zetten voor informatie en interactie over de club, de sport en de leden. De online kanalen vormen samen de virtuele community van de vereniging die, afhankelijk van de aanpak door de club en de leden, verschillende verschijningvormen kan hebben. Met hun virtuele community bieden sportverenigingen, naast de accommodatie, ook een ónline ontmoetingsplek voor sport en andere activiteiten waarmee ze het clubgevoel onder hun leden kunnen bevorderen. Met dit proefschrift geeft Nanny Kuijsters inzichten voor de ontwikkeling van virtuele community’s voor verenigingen, professionals en geïnteresseerden in de georganiseerde sport.
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.
