Generally, Narva is a city with an unorganized post-Soviet public space of relatively low quality. Thus, a very large part of the city’s projects are related to improving the quality of urban space and thereby improving the living environment. The implementation of such projects is extremely costly, with some amounts reaching to tens of millions of euros. At the same time, before the completion or planning of any project, we cannot be sure or guarantee that the quality of the urban space will really increase significantly. Taking into the consideration the intensity of resource while implementing of such projects, it might be important to find a way to check the impact of the proposed changes on the satisfaction of the city residents with public space before making and implementing such significant decisions. As planning and design have now increasingly moved towards the creation of virtual spatial models, virtual and mixed reality tools could also be used to test the impact of the spatial decisions planned on the well-being of residents in the future public space. Having participated with the FinEst Centre for Smart Cities in the 2021-2023 Smart City Ideas project Well-being Score (WBS), we came to the need to find a way to develop further the well-being score tool to be used in measuring well-being in addition to the real space also in the virtual space or in the so-called combined, hybrid reality space. Further, it would be essential for decision-makers to understand the way residents feel regarding the proposed projects through virtual reality tools to ensure the satisfaction of the community and improved living environment.
