The main subject of this chapter is modern digital technologies and the possibilities they offer for design and implementation of hybrid theatrical performances. In particular, Holographic Projection (OP) and Virtual Reality (VR) technologies are presented and explored in practice, as used in the context of the EduSeismArtTec project so as to service its central goal, that of Educational Seismology and Seismology of the Citizens through a hybrid theatrical performance – among other actions of the project.

In a previous chapter, the essential advantages of the theater-pedagogical approach to the education of the general public on important but also critical issues, such as the popularization of science and the response to natural disasters - both goals of Educational Seismology and Citizen Seismology - have been highlighted. The emphasis in this chapter is on the added value that digital technologies contribute in this context, combining the physical with the digital element, so as to transform a theatrical action into a hybrid one. (AEA Consulting for Arts Council, 2016; Tsioustas et al., 2020).

An interesting point, which was also a challenge for the project, concerns the inherent qualitative difference between the two technologies examined: OP is a technology that allows the collective viewing of digital content by the public, because the projection has physical dimensions and an appropriate distance that allows collective viewing.

On the other hand, Virtual Reality and especially immersion type Virtual Reality supports individual viewing, because the subject wears/carries individual equipment (head-mounted display or special glasses and/or controls), which limits viewing/interaction to a strictly individual level . Collective viewing/interaction at this level could be achieved through CAVE systems or through the provision of personal equipment to each member of the audience – solutions both impractical for resource reasons but possibly undesirable by a portion of the audience. Consequently, it seems that Holographic Projection is more suitable to integrate into a theatrical action that constitutes a collective event, in contrast to Virtal Reality which favors an individual approach.

To this challenge, the EduSeismArtTec project gave its own creative response as described below. Based on the above logic, but also to serve the goals of the project, the design, development and integration of the digital material proceeded in 4 phases, which are given here in outline and analyzed in the following paragraphs:

Phase 1: Initially, the digital VR application material was designed and developed, intended for individual viewing through a VR headset, with educational content on the physical phenomenon of the earthquake.
▶ Phase 2: Then the same digital educational content was modified to make it suitable for Holographic Projection. In this form it was incorporated and shown in the stage play Beat the Quake!

Phase 3: Morevover, in the same performance, the insertion of digital material was carried out in a 360-degree projection (augmented scenography). The digital content acted as a backdrop for the theater-documentary performance

Phase 4: Finally, digital content (animation about the earthquake and seismic waves, as well as a virtual instructor) was inserted a posteriori into the captured theater performance (postprocessing of the video), for future educational use.
