Measure lip movement trajectories during web-based experiments carried out using jsPsych. This custom extension (and a related startup plugin) uses MediaPipe's FaceMesh to obtain frame-by-frame estimates of vertical or horizontal lip apertures from the participant's webcam. No identifying facial video/geometry is permanently saved!
