Echos of Footprints aims to reward users with sonic experiences through movement of their bodies.
The interactive sonic installation utilizes the acoustic phonomenon of echolocation to manipulate sound. An ultrasonic sensor array tracks movement and position. Sounds are created when motion is detected. Moving closer and farther away modulates pitch, tempo and delay. Standing still produces no sounds to emphasize movement. The noun echos in Greek means "sound" in general. The name "Echos of Footprints" refers to the changing soundscape as it represents the participator's temporary footprints in space.
Considering how the sensor array is utilized within its environment, how the modules are positioned, and what sounds are produced, all provide a contextual framework for the intended expression.
