Abstract

A system enables a user viewing a plurality of graphical objects rendered on a display screen of a mobile device to manipulate the renderings of each graphical object for purposes of selecting a first of the graphical objects. The system comprises the display screen and a facial proximity system determining the distance of the mobile device from the face of the user. A graphical user interface control system drives a rendering of the graphical objects on the display screen. Further, upon receiving an indication of a change in distance between the mobile device and the face of the user and, upon determining that the distance between the mobile device and the face of the user has changed, the graphical user interface control system modifies at least one of the size of the rendering of the graphical objects and the perspective of the rendering of the graphical objects on the display screen.
