Abstract: A method includes: capturing, from one or more imaging devices, a sequence of time separated images of the subject's face including one or both of the subject's eyes; processing the images to detect specular reflections present in the images, and determining a two dimensional position of any detected specular reflections; characterizing the detected specular reflections into corneal reflections and non-corneal reflections; upon detection of at least one corneal reflection, performing a first eye gaze tracking procedure based on the relative positions of the at least one corneal reflection and at least one reference eye feature; upon detection of no corneal reflections, performing a second eye gaze tracking procedure on one or both eyes of the subject based on the estimation of head pose of the subject; and outputting eye gaze vectors of one or both eyes from the first or second eye gaze tracking procedure.

Abstract: A method of determining the position of eyeballs within an image, the method including the steps of: (a) capturing a time series of image frames illuminated in a predetermined temporal manner by at least two spaced apart light sources, by at least one imaging sensor; (b) processing the image frames to determine specular reflection locations in the image frames; and (c) utilising the time series evolution of the location of the specular reflections to isolate corneal reflections from the determined specular reflection locations.

Abstract: A system and method are provided for actively illuminating and capturing images of an object, such as a driver of a vehicle to reduce glare. The system includes a video imaging camera orientated to generate images of the subject object (e.g., eye(s)) in successive video frames. The system also includes first and second light sources operable to illuminate the object one at a time. The system further includes a processor for processing the image by performing a functional operation to reduce glare in the image. The system may remove glare caused by the illuminators and by external energy sources.

Abstract: A method of determining an eye gaze direction of an observer is disclosed comprising the steps of: (a) capturing at least one image of the observer and determining a head pose angle of the observer; (b) utilizing the head pose angle to locate an expected eye position of the observer, and (c) analyzing the expected eye position to locate at least one eye of the observer and observing the location of the eye to determine the gaze direction.
