Claim One:
1. A system for leveraging user gaze in a user monitoring subregion selection system, the system comprising: a first camera configured to capture an image of a scene; a sensor configured to obtain an image reflected from one of the user's eyes; a gaze estimation and scene mapping module configured to estimate a gaze direction of the user using the image captured by the sensor and to map the estimated gaze direction to the image of the scene based on a location of an object of interest within the scene, wherein the gaze estimation and scene mapping module is configured to estimate the gaze direction by identifying, as a visual axis, a ray that originates at a corneal center of the eye and passes through an adjusted pupil center of the eye, and to map the estimated gaze direction to the image of the scene by projecting the ray into an image plane of the first camera to determine a three dimensional point of regard (PoR) of the user; and a scene subregion selection module configured to select a subregion of the image of the scene based on the mapped user gaze direction.
