This paper presents an interactive theatre based on an embodied mixed reality space and wearable computers. Embodied computing mixed reality spaces integrate ubiquitous computing, tangible interaction and social computing within a mixed reality space, which enables intuitive interaction with physical world and virtual world. We believe it has potential advantages to support novel interactive theatre experiences. Therefore, we explored the novel interactive theatre experience supported in the embodied mixed reality space, and implemented live 3D characters to interact with user in such a system.
