1. A computer-implemented method, comprising:
identifying a specified facial gesture from imaging data of a face of a user;
determining whether the specified facial gesture is indicative of a specified zoom level to be used for displaying the user's face; and
in response to determining that the specified zoom level is to be used instead of a previously-determined zoom level used for displaying the user's face, causing a display showing a video feed of the user's face to change a displayed size of at least a portion of the user's face on the video feed based on a difference between the specified zoom level and the previously-determined zoom level,
wherein identifying the specified facial gesture from imaging data of the user comprises tracking a position of the user's face relative to a reference point or a reference axis to determine whether the user has performed the specified facial gesture, and wherein tracking the position of the user's face relative to the reference point or the reference axis comprises comparing a distance between a facial landmark and the reference point and/or an orientation of a head of the user relative to the reference axis with a threshold indicative of a change to the specified zoom level to be used.
