Echologue, by Orkan Telhan, is a public interface for sensing and displaying socio-cultural characteristics of a place based on its sonic features. The goal is to build a medium that can reflect its surroundings like a smart mirror, highlight the salient details and patterns in the environment and contribute to our understanding of the perception of social places. The interface senses ambient sound, records deliberate user input and displays a visualization of the activity in that space as its output.

The design explores the utility of sound for envisioning new social, cultural and entertainment uses of public places and help us shape our relationships with each other with new social interfaces embedded in urban settings. This medium informs the audience by visualizing the different aspects of the crowd that is otherwise anonymous to each other. The audience listens to a sound collage made of the voices of people telling where they are from and if they can go back or not. As users of the system, we hear words as they are explicitly spoken to the system. The information is used to create a visual representation (based on audio analysis) for designing visuals that display patterns of activity at these location.
