The project “XR-Unites – Collaborative Cultural Offerings with Extended Reality” aims to support the networking and exchange of authors and performers by creating innovative, collaborative cultural offerings with ex-tended reality technology based on existing potentials and offers. The following concrete measures are planned for this purpose: 1. Establishment of an expert board from the existing network of the INKA research group, which has to be expanded by at least 5 new members of the cultural and creative scene (incl. 10 members). 2. Organisation of several interdisciplinary networking events (at least 2 per year), including a workshop offer, in which more than 60 visitors take part. 3. Using collaborative open source authoring systems of the research group for the agile development of several collaborative best practice cultural offerings with XR in different sub-sectors of the cultural and creative industries, resulting in novel interactive multi-user experiences. 4. Several performances of these joint cultural offerings with a total of more than 180 active visitors. 5. Conducting workshops on startup start-up concepts following the respective cultural offerings.
