An evolutionary sonification process based on robotic trajectories

A new approach which integrates an omnidirectional vision system, real world devices, such as mobile robots, and an interactive evolutionary interface for sound production, is presented. Starting with an evolutionary composition system named VOX POPULI and later JaVOX, a hybrid environment named AURAL has evolved. It uses curves drawn in a GUI and trajectories produced by mobile robots to modify the fitness function of a real time sonic composition. An arena was constructed to allow the interaction between robots and to control the variations of sonic parameters producing real time MIDI data. The navigation supervisor system, the sonification environment and graphic results of real time experiments are briefly described.
