My design is based on acoustic, interaction and psychology. I explored the interactive functions of sound and body by establishing an equal communication between listening and interaction. Through listening, touching and viewing external environment, human perceive the external world in a way that sound and visual are interacted with each other. Based on the interaction of sensatory organs and discussion state of mind, it illustrates the inner subtle change of individual. My art applies acoustics theories to reshape the perception of space and image. Sound is an art of time and space, through which it enables us to travel across time.
