The dynamic fingertip recognition realizes the tracking of moving fingertip trajectory, while the static gesture recognition based on convolutional neural network realizes the planning and operation of fingertip trajectory, which generally improves the accuracy and efficiency of the distance learning system. The experimental results show that the gesture recognition system based on convolutional neural network proposed in this study can achieve accurate gesture type recognition, with an average accuracy of more than 98%;Compared with other gesture recognition algorithms, the gesture recognition algorithm proposed in this study has higher accuracy and recognition speed, which are 0.013 s and 99.52% respectively;Compared with the traditional human-computer interactive teaching system, the distance teaching system used in this study has higher efficiency and accuracy when completing various trajectory tasks, and the average time consumption is only 7.235 s. The above experimental results show that the design of human-computer interactive distance education system based on finger tip detection and gesture recognition can effectively improve the quality of distance education, and has certain engineering value for the actual development and design.
