Abstract

Responsive control structures allow graphics systems to be used as performance instruments. Control structures are a design element of a system—while they are manipulated by the user or performer, they exist primarily as a result of the system designer's software and hardware engineering. For example, the control structure of the telephone system allows ten sequential inputs to connect your phone to almost any other in the world. The power of this structure is independent of the specific user control device. Dials, push buttons, tones and clicks can all be used as inputs. While physical controls provide inputs, control structures determine what these inputs do.
