Latest Patents

Junwei Han holds a patent for a method titled "Children visual attention abnormal screening method." This invention involves extracting multi-modal characteristics such as eye movement, facial expression, and head movement of children through multimodal data learning. The method aims to screen mobile terminal visual attention abnormalities in children by utilizing a calibration video and a testing video. The process includes recording a head-face video of children while they watch these videos on smartphones. An eye-tracking estimation model is constructed to predict fixation point locations and extract eye-tracking features. Additionally, facial expression and head posture features are analyzed. A Long Short-Term Memory (LSTM) network is employed to fuse these different modal features, enabling the mapping from multimodal features to category labels. During the testing stage, the head-face video of children is recorded while they watch the videos, and the features are input into the post-training model to determine any abnormalities.
