Abstract

System and method that utilize windowing for efficient capturing of facial landmarks include an inward-facing head-mounted camera that captures images of a region on a user's face utilizing a sensor supporting changing of its region of interest (ROI). The system also includes a computer that detects, based on the images, a type of facial expression expressed by the user, which belongs to a group comprising first and second facial expressions. Responsive to detecting that the user expresses the first facial expression, the computer reads from the camera a first ROI that covers a first subset of facial landmarks relevant to the first facial expression. Responsive to detecting that the user expresses the second facial expression, the computer reads from the camera a second ROI that covers a second subset of facial landmarks relevant to the second facial expression, with the first and second ROIs being different.
