A system, method and computer program product provides for determining a location of an external object sensed by a mobile object on a display of the mobile object. The method may include determining a first position of the external object on the display, the first position being sensed by the mobile object at a first position of the mobile object. It may also include determining a second position of the external object on the display, the second position being sensed by the mobile object at a second position of the mobile object. Next, the method may include determining the location of the external object based upon said determining of the first position and said determining of the second position. The first position of the external object and the second position of the external object may be respectively sensed by a sensor system of the mobile object, where the display comprises a graphical user interface (GUI). Any portion of the external object may be mapped to one or more pixels, with each pixel providing a unique location.
