Traditional GUI interaction models are flat, planar, and two-dimensional (2-D). You can use some two-and-a-half dimensional (2.5-D) techniques (such as skewing planes, adding shadows, and overlapping elements) to make some objects look as if they have depth. In contrast, in a touch NUI interaction, models go beyond a simple plane to provide depth, encourage immersion, and make objects appear to have volume or take on real-world three-dimensional (3-D) behaviors ...
