The NUI is truly a huge jump in computing, in fact, Microsoft said that it is “as significant as the move from DOS to GUI”. Let’s take an example to prove it – how about the simple task of making an image bigger. In DOS, well, it isn’t really plausible. In a GUI it is very tedious. You would have to select the image, fill out forms on how much bigger you want the horizontal to be, do the same for the vertical, and click submit (and possibly do this again if you guessed the wrong size). In a NUI, it’s MUCH simpler. Put your two fingers down and resize. Walla! Not to mention that you can physically see how much bigger it is while you resize it, and you can resize it continuously.

Microsoft Surface further defines the NUI by allowing for real world objects to easily “communicate” with the digital interface of Surface. By allowing these real world objects, the interface becomes even more “natural”, because the objects on the surface (you can capitalize that “s” if you’d like) are actually a real, natural object.
