Mixed-reality digital interactive performance is a new style of performance art that facilitates impromptu interactions among dancers and virtual characters in real time. However, such performance is difficult to conduct as the performance designer has to deal with the asynchronous events and temporal requirements of interactions among performers, virtual characters, and music, which are tedious and error-prone. This paper presents the design and implementation of a domain-specific language called DIPS (Digital Interactive Performance Sketch) that aims to help directors of such performance test their ideas quickly. On the surface, DIPS provides the common domain abstractions and their associated operations for performance with simple rule syntax that simplifies the task of designers to a large degree. Behind the scenes, DIPS is realized through a combination of a number of established language embedding techniques on the Scala language and some middle-level facility based on the Scala Akka library. To evaluate DIPS, we have implemented a language workbench and an execution engine together with an application called the Future Circus. The preliminary evaluation results are encouraging and demonstrate the feasibility and effectiveness of DIPS.
