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.
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.
Virtual training systems provide highly realistic training environments for police. This study assesses whether a pain stimulus can enhance the training responses and sense of the presence of these systems. Police officers (n = 219) were trained either with or without a pain stimulus in a 2D simulator (VirTra V-300) and a 3D virtual reality (VR) system. Two (training simulator) × 2 (pain stimulus) ANOVAs revealed a significant interaction effect for perceived stress (p =.010, ηp2 =.039). Post-hoc pairwise comparisons showed that VR provokes significantly higher levels of perceived stress compared to VirTra when no pain stimulus is used (p =.009). With a pain stimulus, VirTra training provokes significantly higher levels of perceived stress compared to VirTra training without a pain stimulus (p <.001). Sense of presence was unaffected by the pain stimulus in both training systems. Our results indicate that VR training appears sufficiently realistic without adding a pain stimulus. Practitioner summary: Virtual police training benefits from highly realistic training environments. This study found that adding a pain stimulus heightened perceived stress in a 2D simulator, whereas it influenced neither training responses nor sense of presence in a VR system. VR training appears sufficiently realistic without adding a pain stimulus.
The key goal was to further develop, secure and disseminate knowledge and concepts concerning the role of high realism in Virtual Reality. It followed the Digital Media Concept professorship to create and examine the effects of high quality worlds and characters in VR. Key focus was on the effect of high versus low realism in (existing and non-existing) digital environments as well as digital characters and avatars (digital representations of human users) and embodied agents (digital representations of computer programs that have been designed to interact with, or on behalf of, a human). This means on the one hand getting better equipment and skills to digitize and create high realistic avatars in VR. And on the other hand this means that a better understanding of the concept of realism and quality is needed. This encompasses a whole range of terms that varies from realistic resemblance, to high fidelity appearance and (real-time interactive and authentic) behaviour based on high AI programming. Research showed that very important is congruency in realism between elements within a VR world. Furthermore it showed that high realism is not always needed to stimulate ‘real’ (VR) behaviour. High immersive experiences and impulse behaviour also functions in virtual environments that have lower levels of realism. Studies have been conducted within the field of health, entertainment, advertising, architecture and journalism. An example is the VR game Descend, see link (used to examine the effect of realism through resemblance).Partners: Radboud University, Enversed, Stanford University, University of Oregon, Cornell University, several companies
