The main research areas of emotional design have been divided into three parts, which are product form, function and culture. However, culture-related emotional experience has less research results to date. In this paper, we combine a unique approach with three levels of emotional design. Co-pulse is an optical media service system for musical performances. It consists of two main parts, one part is the programmable spotlight with its coding system, and the other part is the intelligent illuminated wristband worn by the audience. The entire system uses light as both the media and the signal transmission method. It can show wonderful scenes rendering visual effects followed by the music features, and also achieve the WYSIWYG communication effect. Encoding the visible light actualizes all this.
