If the existing legacy media was a form of one-sided delivery of content from an unspecified majority, the development of technology has now transformed various forms of media into actively communicable media. Thus, the project, Melody Curtain, was designed to transform the six-floor information science building into a vibrant and active space, not a quiet, passive space. When the audience passes through the project, the ultrasonic sensor recognizes the distance between the audience and the project and enters the audience within a meter, which makes the tubla Bell sound by hanging several metal tubes in a row. In addition, a cylindrical device that shapes the tubular bell is used to move vertically up and down by the servo motor and communicate more vividly with the audience. It is expected that students using the Information Science building will be more interested in the six-floor, and they will see the sixth floor as a charming place, not a static one anymore. The paper also describes the specific technology implementation methods of this project, along with the goal of eliciting voluntary action from the audience.
