The invention provides a man-computer 
interaction method for an intelligent 
human skeleton tracking control 
robot on the basis of kinect. The man-computer 
interaction method includes the steps of detecting actions of an operator through a 3D depth sensor, obtaining data frames, converting the data frames into an image, splitting objects and background environments similar to a 
human body in the image, obtaining depth-of-
field data, extracting 
human skeleton information, identifying different positions of the 
human body, building a 3D coordinate of joints of the 
human body, identifying rotation information of skeleton joints of the two hands of the human body, identifying which hand of the human body is triggered according to catching of changes of angles of the different skeleton joints, analyzing different action characteristics of the operator, using corresponding characters as control instructions which are sent to a 
robot of a lower computer, receiving and 
processing the characters through an AVR single-
chip microcomputer master controller, controlling the 
robot of the lower computer to carry out corresponding actions, and achieving man-computer interaction of the intelligent 
human skeleton tracking control robot on the basis of the kinect. According to the method, restraints of traditional external equipment on man-computer interaction are eliminated, and natural man-computer interaction is achieved.
