The use of holographic showcases inside the museum's context. Towards an advanced museology creating a dramaturgy around the exhibited objects

A new challenge, in the museological domain, is the use the holographic effect of Pepper's Ghost to develop a novel frontier in storytelling inside museums, integrating in the same space real and virtual contents, and creating a virtual dramaturgy around the real object. This integration has a communicative potential never seen before inside museums, because it works in perfect harmony with the museum visit and the real artifact is kept in the middle of a lively experience of mixed reality. Narration is a central issue, because it involves not only creative and technological but also "ethical" and cultural choices, inherent the scientific correctness and plausibility of contents, while using agile and multiform tools like the digital ones. Case studies will be discussed, presented and tested on the public in different European museums, in the framework of the EU project CEMEC. In fact within this project we have conceived the "box of stories" a holographic showcase where (a) integration of real and digital contents, (b) structure, (c) materials, (d) interior setup, (e) illumination, (f) narrative approach and dramatization, (g) scalability are designed as a whole. Since the holographic effect is an illusion of reality, there are specific rules and constraints regarding technical set up, perception and editing of contents that must be respected and that will be discussed.
