Gestures: Gestural Interaction and Gesturalization

We have so far seen that the BigBang rubette allows users to visualize and sonify facts, and create and manipulate them using processes. In the previous chapter, we also discussed that the only structures that BigBang represents internally are processes, only one of which refers to facts in the form of denotators (InputComposition). All other facts are generated dynamically, whenever an operation is added or modified. In order to offer an intuitive way of interacting with the software, we need yet another level: gestures.
