ABSTRACT:
A system and method for zooming an object through a spiral movement of a pointer. The method provides three-dimensional interaction with an object in response to a two-dimensional pointer input. The method includes monitoring pointer movements to determine whether a movement indicates a spiral movement. When a spiral movement is determined an object is zoomed. A clockwise spiral movement may zoom an object inwardly and a counterclockwise movement may zoom an object outwardly. A non-spiral movement may pan the object.
