The Fresnel lens on the top projects molecular animations of the product ingredients. The central lifting platform is equipped with holographic projection equipment. When the singer sings, virtual petals interweave with the 3D model of the product over the stage. The interactive device area on the edge of the stage is equipped with a sound-wave sensing wall. When the audience touches it, it will bloom with LED simulated flowers of corresponding colors. The cold fireworks in the product release process cooperate with the stage robotic arm to allow music performances and commercial displays to be completed in laser lights and electronic sound effects.
