Latest Patents

Chi Zhang holds a patent for a method titled "Children visual attention abnormal screening method." This invention involves extracting eye movement, facial expression, and head movement multi-mode characteristics of children based on multimodal data learning. The method aims to screen mobile terminal visual attention abnormalities in children by utilizing a calibration video and a testing video. It records 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 from the head-face video, allowing for the extraction of eye-tracking features. Additionally, facial expression features and head posture features are extracted. A Long Short-Term Memory (LSTM) network is employed to fuse different modal features and realize 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 whether they exhibit abnormal visual attention.
