[Abstract]:Human computer interaction (HCI) technology is an important factor to study the communication and interaction between users and computers, which determines whether the system is "friendly" or not. The principle of human-computer interaction is to interact with computer system by using various actions and subtle changes of human body itself. This new form of interaction greatly improves the recognition accuracy and humanization of interaction. As a common way of communication, gestures play more and more popular roles in the field of interaction between human and machine, such as Xbox, smart phone, billboard and so on. The gesture recognition control robot not only allows the user to manipulate the remote robot through natural gesture action, but also ensures that the user can interact with the developing network robot system in a "friendly" way. Nowadays, with the development of robot science, robot has more and more powerful vitality, and the intelligent motion technology of mobile robot is an important subject to study robot. How to communicate with robots by non-contact gestures in a natural environment is the main focus of this paper. In this paper, kinect sensor and X 80 mobile robot are used to control the movement of robot. The main contents are as follows: (1) based on the working mechanism of the kinect sensor and the operation principle of the device, five kinds of natural interactive gesture templates are designed, including forward, backward, right turn. Turn to the left and stop. (2) by comparing the merits and demerits of the hidden Markov model algorithm and the dynamic time warping algorithm, a relatively efficient algorithm named dynamic time warping algorithm, which is suitable for the research of this paper, is selected. The optimization is carried out by limiting the global path and the distortion threshold. Using the optimized dynamic time warping algorithm to verify the accuracy of the above five gesture recognition. (3) based on pid principle and wireless robot software development kit, according to the result of gesture recognition, the decoder outputs the corresponding variables. In order to control the operation of the wireless robot motor. (4) the movement of the X80 robot is controlled by the gesture recognized by kinect.
