A guide to how you can minimize errors and employ workarounds for facial tracking problems associated with wearing glasses. These problems include random blinking of one eye, one or more eyes remaining shut, and one or more eyes looking in the wrong direction. Maybe a setting to lock eyes being synchronous that can be turned on/off. Maybe a timer for blinking that you can select instead of camera input. Maybe a way the video can take a still and then you confirm what is the eyelid, what is the pupil, and maybe confirm what are the glasses.
