The coming forth of kinect technology has enabled trainers controlling cruise and operation in 3D scene by their action, but this technology isn’t applied to electric power training field yet, because this field includes many electric devices and operation regulations. This paper has firstly described the electric operation regulations as one set of operation patterns by using finite state machine technology, then matched the operation information gained by a kinect device to these patterns by using the Dynamic Time Warping algorithm, so that the action type of trainer can be recognized. At the same time, this paper has controlled the cruising velocity of a virtual man in 3Dscene by enabling the action synchronization of trainer and virtual man, and controlled the display effect of collision by adjusting the attributes of Unity visualization objects when the virtual man operates an electric device. So, trainers have been immersed into 3D scene of substation and gained more deep training effect.
