AURAL: An Evolutionary Interface for a Robotic Sonification Process

A new approach is presented which integrates an interactive evolutionary interface for sound production, real world devices, such as mobile robots, and an omnidirectional vision system. Starting with an evolutionary composition system named VOX POPULI and later JaVOX, a hybrid environment named AURAL has evolved. It uses curves drawn in an 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 controlling 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 described.
