  • POSE-INVARIANT EYE-GAZE TRACKING USING A SINGLE COMMODITY CAMERA
    Publication number: 20190087001
    Abstract: A method, comprising: (a) measuring coordinates of four or five fiducial markers in facial images of a subject captured by a camera facing away from a screen toward the subject; (b) optimising and reducing a multivariate polynomial model that maps the measured coordinates of the four or five fiducial markers in the facial images to estimated coordinates of gaze targets of the subject on the screen; and (c) using the reduced multivariate polynomial model to map the measured coordinates of the four or five fiducial markers to the estimated coordinates of gaze targets of the subject on the screen.

  • Detection of mobile phone usage
    Patent number: 9888080
    Abstract: Systems, methods and apparatuses for detecting the use of a mobile communications device while driving a vehicle. Data from a vehicle is correlated with data on the use of a mobile communications device to determine if the mobile communications device was used at the same time as the vehicle was in operation. The respective locations of the mobile communications device and vehicle are correlated to determine if the mobile communications device was in the same location as the vehicle.
