Abstract
The present teaching relates to method, system, medium, and implementations for identifying object of interest. Image data acquired by a camera with respect to a scene are received. One or more users are detected, during a period of time, from the image data who are present at the scene. Three dimensional (3D) gazing rays of the one or more users during the period of time are estimated. One or more intersections of such 3D gazing rays are identified and are used to determine at least one object of interest of the one or more users.
