    • There is provided a system and method for controlling a tracking device to follow a location of a performer on a stage. The tracking device may comprise a lighting fixture such as a high output video projector or an automated mechanical moving light such as a DMX lighting fixture to provide a followspot, or a microphone to record audio from a particular performer. The method comprises capturing a video feed of the stage using a camera, presenting the video feed on a display of a control device, receiving input data indicating a position of the performer in the video feed, translating the input data into the location of the performer on the stage, and adjusting the tracking device to follow the location of the performer on the stage. The control device thereby provides lighting operators with an intuitive interface readily implemented using cost effective commodity hardware.
