What will tomorrow’s theatre look like?

At the interface of analogue spaces and digital worlds we are looking for answers to this question.

digital.DTHG is the new field of competence of the German Theatre Technical Society. We investigate the potentials of digital technologies for theatre and develop basic model solutions in several research projects. Likewise, digital.DTHG sees itself as a contact partner, discussion forum and communication platform – not only for members of DTHG, but for the entire theatre landscape.

The first research project “Im/material Theatre Spaces – Augmented and Virtual Reality for Theatre” has started on October 1, 2019 for a period of two years. This project is funded by the Federal Government Commissioner for Culture and Media. In various sub-projects we develop specific approaches for the sections of theatre architecture, stage technology and stage design.


The aim is to explore new technical possibilities at the interface of analogue and digital worlds and to make these usable for theatre professionals.

Existing knowledge and existing solutions from other fields of research, work and disciplines are thereby adapted to the specific conditions of theatre. Through international cooperation with universities, museums, politics and industry, we bundle interdisciplinary competences. In this way, together we create a sustainable and practical digital future vision for the theatre.

Virtual theater architectures and co-creative performance spaces

What is the relationship between theater and immersive technologies? What spatial, technical and narrative qualities does a medium like virtual reality offer? Which aspects are important?

Spatial narratives in virtual reality

What dramaturgical and scenographic means do we use to design virtual experience spaces? How can a room be set in motion virtually? And how do visitors immerse themselves in such a moving space?

Actors in co-creative playing environments

When looking at the design possibilities for a VR production, it helps to first draw attention to the target audience:

Cocreative performances in Hybrid-real stage spaces

When the audience is integrated into an artistic performance through the use of participatory strategies, the suggested cooperation at eye level often takes place only superficially. The participants are only given limited power to act and are usually involved in the supposedly collective creative process without authorship.

Quickly recommended: Festivals & Awards for Extended Realities

Festivals, as in all artistic disciplines, offer a very good framework in the case of Extended Realities to exhibit new ideas, concepts and works and to make them accessible to a large audience.
