Heron’s Soundscape is a generative musical composition designed as an interactive augmented reality (AR) experience, to be played by participants using mobile devices and the “Heron’s Dreamscape” mural as a visual score. Sound and visual accompaniment is created in real-time through participants’ direct interactions with the mural. Audience members create one or more “performances” of the piece determined by their choices and interactions, including the angles, locations, and paths they trace visually with their mobile devices while hearing the results of each engagement in relation to the images presented upon their device’s viewfinder.
