In urban planning, 3D modeling and virtual reality (VR) provide new means for involving citizens in the planning process. For municipal government, it is essential to know how effective these means are, to justify investments. In this study, we present a case of using VR in a municipal process of civic participation concerning the redesign of a public park. The process included codesign activities and involved citizens in decision-making through a ballot, using 3D-rendered versions of competing designs. In codesign, 3D-modeling tools were instrumental in empowering citizens to negotiate design decisions, to discuss the quality of designs with experts, and to collectively take decisions. This paper demonstrates that, in a ballot on competing designs with 1302 citizens, VR headsets proved to be equally effective compared to other display technologies in informing citizens during decision making. The results of an additional, controlled experiment indicate that VR headsets provide higher engagement and more vivid memories than viewing the designs on non-immersive displays. By integrating research into a municipal process, we contribute evidence of cognitive and engagement effects of using 3D modeling and immersive VR technologies to empower citizens in participatory urban planning. The case described in the paper concerns a public park; a similar approach could be applied to the design of public installations including media architecture.
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.
This qualitative research note reports two neglected themes in research on virtual reality tourism experiences, i.e. its potentially addictive nature and temporary sense of isolation. Existing work on virtual reality tourism experiences has applied existing knowledge and theories and has solely tested how VR applications can positively mediate or moderate the tourist experience. This study adopted an inductive approach, analyzing contents of reviews and blogs, and consequently uncovered a temporary sense of isolation and the addictive nature of virtual reality as hidden themes within virtual reality tourism experiences. We stress the importance of further work on addiction and a sense of isolation in terms of their nature, role, and effects
Flying insects like dragonflies, flies, bumblebees are able to couple hovering ability with the ability for a quick transition to forward flight. Therefore, they inspire us to investigate the application of swarms of flapping-wing mini-drones in horticulture. The production and trading of agricultural/horticultural goods account for the 9% of the Dutch gross domestic product. A significant part of the horticultural products are grown in greenhouses whose extension is becoming larger year by year. Swarms of bio-inspired mini-drones can be used in applications such as monitoring and control: the analysis of the data collected enables the greenhouse growers to achieve the optimal conditions for the plants health and thus a high productivity. Moreover, the bio-inspired mini-drones can detect eventual pest onset at plant level that leads to a strong reduction of chemicals utilization and an improvement of the food quality. The realization of these mini-drones is a multidisciplinary challenge as it requires a cross-domain collaboration between biologists, entomologists and engineers with expertise in robotics, mechanics, aerodynamics, electronics, etc. Moreover a co-creation based collaboration will be established with all the stakeholders involved. With this approach we can integrate technical and social-economic aspects and facilitate the adoption of this new technology that will make the Dutch horticulture industry more resilient and sustainable.
Circular Economy is a novel disruptive paradigm redefining sustainability in the hospitality industry and addressing the environmental challenges set by this fast-growing impactful industry. To address these challenges, the creation of further knowledge on circular economy and its applications in the hospitality sector is fundamental, together with providing hoteliers and restaurateurs with proper skills and knowhow to tackle such challenges. Drawing on a on going pilot project on Circular Economy in Hotels in Amsterdam, the Friesland hospitality sector and the Professorship of Sustainability in Hospitality and Tourism at NHL Stenden University of Applied Sciences have set out to develop an innovative learning experimental environment in which Friesland hoteliers and restaurateurs can develop further knowledge and identify - together with students, researchers, and experts – possible key actions and strategies to implement regenerative circular processes of material up-cycling. To which extent this learning community of the Northern Netherlands contributes to develop wider knowledge on circular economy in hospitality and to identify, implement, and test innovative regenerative circular actions will be evaluated.
Professionals van woningbouwcorporaties en gemeentes die zich bezig houden met verduurzaming hebben vragen over hergebruik van afvalhout uit hun (renovatie) projecten. De doelstelling van dit voorstel is het onderzoeken van de mogelijkheden om hout te hergebruiken door gebruik te maken van innovatieve digitale productietechnieken, en om implementatiestrategieën hiervoor te ontwikkelen voor publieke organisaties in de bouwsector, in het bijzonder woningcorporaties en gemeentes. Strategieën omvatten concrete voorstellen om a) afvalhout van woningen in te zamelen en te verwerken; b) waarde toe te voegen aan houtafvalstromen door middel van digitale productie; c) de betrokkenheid en acceptatie van huurders te vergroten bij circulaire verwerking van hout in nieuwe toepassingen; en d) goede toepassingen voor een circulaire economie te realiseren. Het project onderzoekt aard en omvang van houtafvalstromen uit woningrenovatie en identificeert de mogelijkheden voor het hergebruik van specifieke fracties daarvan voor (lokale) toepassingen. Uit voorgaande projecten blijkt dat digitale productie mogelijkheden biedt om stedelijk afval om te zetten in zinvolle circulaire producten. Digitale productie maakt de (lokale) creatie van unieke prototypen en grootschalige toepassingen mogelijk. Het onderzoek wordt uitgevoerd in vier werkpakketten. De eerste identificeert de aard van huishoudelijk houtafval (volume, houtsoort, verzamelproces) door zorgvuldig cases van Ymere en Rochdale te bestuderen. Daarnaast worden er een raamwerk van indicatoren gedefinieerd om projectresultaten te kunnen evalueren. Het tweede werkpakket onderzoekt welke toepassingen kunnen worden bedacht, gegeven de beschikbare houtfracties. In het derde werkpakket wordt een aantal case studies uitgevoerd voor concrete projecten van de deelnemende woningcorporaties. Deze applicaties hebben als doel het potentieel van digitale productie met houtafval te laten zien, rekening houdend met het perspectief van bewoners. Het biedt belangrijke inzichten in de uitvoerbaarheid van concrete toepassingen uit teruggewonnen hout. In het vierde werkpakket worden alle projectbevindingen gecombineerd in een set implementatie strategieën voor publieke organisaties in het stedelijk domein.
