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.

Abstract: Disclosed herein are systems and methods for tracking facial expressions efficiently. In one embodiment, a system includes a non-contact head-mounted electro-optical sensor (e.g., an inward-facing head-mounted camera), which measures reflections from a region on a user's head, which are indicative of facial expressions of the user. The system also includes a computer that detects, based on the reflections, a type of facial expression expressed by the user, which belongs to a group comprising neutral facial expressions and non-neutral facial expressions. The computer uses this detection to determine how to proceed to read the electro-optical sensor: the computer reads the electro-optical sensor at a first average bitrate (b1) when the user expresses a facial expression from among the neutral facial expressions, and reads the electro-optical sensor at a second average bitrate (b2) when the user expresses a facial expression from among the non-neutral facial expressions, where b2>b1.
