Abstract

Aiming at the problem of shelter of identification and concentration analysis such as wearing masks in offline learning under the background of epidemic situation, the identification method of action energy map based on change of eye and the concentration analysis method based on eye movement offset were proposed. The eye contour maps in a complete blink cycle were extracted from the self-built blink database videos to synthesize the action energy map. Wavelet packet decomposition was used to extract features, and kernel principal component analysis (KPCA) was used to reduce the data dimension, then support vector machine (SVM) was selected for classification training. The accuracy can reach 95%. The gradient center algorithm was used to get the eyeball center and collect the videos in the states of focus and non focus in the online class, then the Manhattan distance between the eyeball center and the eye contour center was used to measure the eye movement offset, finally the threshold to divide focus and non focus was defined.to optimize the interactive effect of online education.
