Abstract

A system to detect a gaze at an object by utilizing an image sensor is disclosed. The system includes a processing subsystem including a detection module to detect at least one face of a person. The detection module is to identify a gender of the person. The processing subsystem includes a depth estimator module to estimate a distance of the person from the image sensor. The processing subsystem includes a height estimator module to estimate a height of the person. The processing subsystem also includes a horizontal position estimator module to estimate a relative position of the person with respect to the image sensor. The processing subsystem includes a computing module to compute a range of pitch angle and a range of yaw angle. The processing subsystem includes a recognizing module to recognize the gaze of the person.
