3D interactive performance space, such as machinima, lacks intuitive control mechanisms. Set direction and acting are limited by the technical toolsets available to creators, as the tools were designed to create video games rather than cinematic works. They do a poor job of capturing the performative expression that characterizes the more mature medium of film. The TUI3D project is joint research between Synlab, the Experimental Games Lab and Machinima Group at Georgia Tech that addresses production and performative challenges involved in creating machinima. We are developing a suite of tangible interfaces that could be used to create and control three aspects of 3D virtual environments in real-time: character, camera, and space. Tangible interfaces can help bridge gap between computer film creators and the established base of traditional film creatives and their knowledgebase. We also anticipate deeper and more convincing expression with these more user-centered tools.
