Gaze Point Detection Using Dynamic Facial Reference Points Under Varying Lighting Conditions

摘要

Methods, systems, and computer program products for gaze point detection using dynamic facial reference points under varying lighting conditions are provided herein. A computer-implemented method includes detecting items of spatial information pertaining to at least one eye of an individual gazing at one or more objects; detecting an item of spatial information pertaining to at least one nostril of the individual; detecting items of spatial information pertaining to the head of the individual; assigning a distinct weight to each of (i) the spatial information pertaining to the at least one eye and (ii) the spatial information pertaining to the at least one nostril based on the spatial information pertaining to the head; and generating gaze detection parameters applicable to the individual based on (i) the weighted spatial information pertaining to the at least one eye and (ii) the weighted spatial information pertaining to the at least one nostril.
