Classroom Attention Detection Based on Computer Vision and Artificial Intelligence

: The academic level of students is the core issue that schools and parents pay attention to. There is a close relationship between students' academic level and students' attention status in class. Students who can maintain their concentration for a long time tend to have higher academic level. Therefore, it is very necessary to improve students' attention level in class. To this end, the attention of the students needs to be detected first. Computer vision algorithms typically employ third-person image or video data. Due to the large number of students in the classroom, the algorithm is difficult to extract small objects and occluded objects, so it cannot accurately detect students' attention. The attention detection model proposed in this paper included three modules: gaze point estimation, gaze target recognition and attention level analysis. The gaze estimation module used a deep learning algorithm that combines saliency detection with attention shifting. In order to improve the accuracy of the algorithm, this paper tried three attention mechanisms, namely spatial attention, channel attention and mixed attention. The specific approach was to embed the attention module after the convolution block of the Convolutional Neural Network (CNN). In order to achieve the goal of obtaining students' classroom attention data in batches and accurately, this paper proposed a first-person video-based student classroom attention detection method. Compared with the third-person video,
