An optical media disk is treated with a light-sensitive material that impedes the ability of an optical media player from reading data stored on the disk. Based on the first information, determining second information indicating a transformation relation between a gesture movement of the part of the human body and an effected change of the control parameter by the gesture movement. By the specific arrangement of these internal elements, the package structure generates full-color light with high resolution, compact structure and high mixing uniformity, and also achieves low cost and decreases usage of space.
