Drive Mind is a unique electro-acoustic system, which offers an audience a new sonic experience produced by the refraction of light. The main feature of this system is to visualize abstract figures of sound using a ray of LED light and to manipulate the system using acrylic objects. By this manipulation, the system creates a refraction of light and attendant positional data. This positional data is used to produce sound. The complexity of refraction of the light and the frame rate of the camera cause subtle fluctuations and produce distinctive sounds. The object is to enhance an audience's imagination by enabling them to identify with the performer's action visually, and help understanding of complex digital expression, using not only physical material but also physical phenomena when operating the system. This system helps the audience to become familiar with complex digital expression and experience the new possibilities of sound art.
