Abstract

A method for converting a two-dimensional (2-D) graphic user interface (GUI) into a GUI with a three-dimensional (3-D) effect includes: defining a GUI display region on a screen, the GUI display region being defined by first and second curved lines that are spaced apart from each other in a first direction, and first and second boundary lines that intersect the first and second curved lines, distances between pairs of points respectively on the first and second curved lines and aligned in the first direction varying in a second direction different from the first direction; performing projection transformation computational processing upon content of the 2-D GUI to result in transformed content; and presenting the transformed content in the GUI display region, the transformed content presenting a 3-D effect. A system that performs the method is also disclosed.
