In carton manufacturing industry, traditionally, new workers are trained by realistic machines. However, training operators in a virtual environment can significantly reduce the budget and avoid unexpected safety accidents. In this paper, we presented a new interactive way in industrial training system based on Kinect. By computing depth map, Kinect sensor can produce the features of human body in real scene. The potential application of Kinect as a gestural interaction tool for equipment simulation training is evaluated in our system. Users can take use of the interactive interface quickly and apply it to navigation through a real-time 3D virtual environment created by Unity3D.
