Chapter 17 DOI: 10.4018/978-1-7998-2823-5.ch017 ABSTRACT In the learning society, knowledge is the new capital, and the role of the designer encompasses a vision- ary and imaginative force that must translate the cultural dimension of the project into formal expres- sions but also ensure a functional and environmental character that is nowadays enhanced by digital technologies. Design does not solely restrict itself to designing the experience of use, the “economy of experience,” but introduces an innovative vision of systems or innovative access to cultural heritage in all its forms. The chapter exploits methodologies to support the experiential design process where the tools of representation are critical to simulate, prototype, and build interiors but also arrange the right set to control and validate the fnal perception of a space. A participatory application for the Cola Filotesio museum of Amatrice concludes the chapter: a prototype of a community center to replace by the means of a virtual environment the church of Saint Emidio, which was razed to the ground by the 2016 earthquake.
