By the results, the system can open the speaker’s files automatically. Then the Kinect camera is used to get the tracking data of palm. On the basis of the data, the two-dimensional image is divided into several function parts. The least square method is adopted to convert the two-dimensional tracking data at different depth and the intention of the speakers is gotten. The purpose of controlling the PowerPoint without touching is realized. The simulation results show that the method is effective. %U http://cea.ceaj.org/EN/abstract/article_30892.shtml
