Past,Present,and Future:The Practice and Exploration of Digital Performance Arts in German-speaking Countries

This article characterizes the development of digital theatre in German-speaking countries,spanning the periods before,during,and after the Covid-19 pandemic,and provides an overview of several representative formats for digital performances.These formats encompass various approaches,such as facilitating the transformation of public theatres'social identity through online forum mechanisms,engaging in transmedia production across time and scenes,developing mobile applications,participating in performances via cameras,and live broadcasts of online auctions.It was argued in the article that digital theatre is increasingly solidifying its place within the German-speaking theatre landscape,with the traditional unidirectional linear performance model transitioning into an era characterized by interactive,globalized,virtual,and multidimensional online and offline performance in the future.
