Improv Remix: Mixed-Reality Video Manipulation Using Whole-Body Interaction To Extend Improvised Theatre

Improv Remix is a mixed-reality system for live onstage video editing, using whole-body interaction, as an extension of improvised theatre. This work documents the process of analyzing an art form, then building technology that supports its extension. We tested the potential for video integration in improv in a exploratory workshop, then determined features and interaction techniques through iterative development with improvisors. We demonstrated the final iteration in a public showcase. Our contributions are (1) the documentation of the process, (2) a basic set of always-on interaction techniques tailored for performers standing adjacent to a large display, (3) methods to remix stage performance video, and, (4) a collection of creative use cases for the system, with an analysis of how the system extends improvisation.
