This paper argues for new approaches to the design of sound for contemporary interactive technologies. We begin by presenting what we feel to be the key challenges as yet unaddressed by conventional auditory display research. Subsequently, we propose a user-centered, acoustic ecology-informed, design method that we feel can be built upon to inform the design of sound for contemporary interactive technologies, thus tackling some of the challenges introduced. Our approach consists of three stages: firstly, encouraging designers and users to experience the original auditory environment, identifying the key sounds within that environment, and then summarizing this information into an 'earwitness account' that can be used as a prelude for inform...
