A disclosed system is configured to estimate an attention state of a subject within a scene. An imaging camera captures digital images of the subject and one or more light sources illuminate the subject during a period in which the digital images are captured. The system also includes a processor that processes the captured images to generate subject attention data of the subject. The processor further generates a primary visual attention ray of the subject from current subject attention data; generates a distribution of visual attention rays having an origin common to the primary visual attention ray; projects the visual attention rays onto a digital representation of the scene having a plurality of predefined regions of interest; determines an intersection of the projected visual attention rays with one or more of the regions of interest; and based on the intersection, estimates an attention state of the subject's attention.
