Abstract: Methods, apparatus, systems, and articles of manufacture to measure facial attention are disclosed. An example apparatus includes at least one memory, machine readable instructions, and processor circuitry to at least one of instantiate or execute the machine readable instructions to identify facial landmarks from input image data, the facial landmarks corresponding to coordinates of landmarks of a face detected in the input image data, determine a first distance between a first facial landmark of the facial landmarks and a second facial landmark of the facial landmarks, determine a second distance between the first facial landmark and a third facial landmark of the facial landmarks, and compare a quotient of the first distance and the second distance to a threshold to determine an attentiveness metric.
