Longlisted for the PQ Best Publication Award in Performance Design & Scenography 2023 Immersion and Participation in Punchdrunk's Theatrical Worlds is a detailed account of the company's award-winning productions and their historical context. Examining Punchdrunk's role as pioneers of immersive theatre in the UK through a range of their productions including Sleep No More and The Drowned Man besides theatrical works such as Faust, The Duchess of Malfi and Kabeiroi, and cross-platform productions like The Moon Slave, The Borough and The Oracles, the book presents an original framework for understanding immersion in theatrical and mixed reality experiences. Central to the book is a study of how immersive experience is produced in interaction with physical and digital scenography for participatory audiences. Through ethnographies of the company, their designers, actors, producers and audiences, the book interrogates the relationship between the aesthetics of interaction and the experience of immersion in Punchdrunk's work. The theoretical framework that the book introduces affords analyses of material cultures and the influence of technology on interaction design in theatre and beyond, and offers a blueprint for next-generation immersive design and scenography for interactive multimedia environments.
