Lighting is one of the essential elements of the theater. With the advancement of interactive technology, It is possible for performers to control the parameters of the moving stage light through gestures or body movements directly. In this paper, an interactive lighting system controlled by the performer's body movement is proposed. Performers wearing Myo Armband, a gesture sensing device, can interact with the moving stage light, controlling the orientation, colors, brightness, flickering patterns, and timing, through the user-friendly graphical interface.
