Echo Wall: A Sound-driven Media-art

Echo Wall is an interactive artwork, which enables people to communicate with the environment and other people in everyday setting. The installation is set up on a regular wall in public where everyone could participate in the interaction. When one speaks or makes noise in front of the wall, the projected animation on the wall will change according to the location and the voice features of the person. People can communicate with each other by generating different animations. The microphone array technology used provides people with an opportunity to experience the interaction more naturally without any complicated equipment.
