The touch screen has been widely used, and touch gestures will replace the mouse and the physical keys like the input gradually, taking the new experience for the popularization of electronic products such as mobile phones and computers.
Natural and intuition. Everyone knows how to click with fingers, it easier to operate if it sames like the objects in our daily life, which is one of the characteristics of the natural user interface (NUI-Natural User Interface).
Less intrusive. Typing and mouse clicks with sound, but the touch screen is silent and convenient, you just need use your finger, no need to find a pen.

Difficult to enter. Limited space to touch, it is difficult to change the cursor position and the virtual keyboard call to the large section.
Difficult to click on the edge of the screen area. With one hand hold the touch-screen phone, the thumb, thumb long as the radius of the phone screen about a quarter of the ring area most easily to click on the farther from this area, the more difficult to click.
The so-called design, is to solve the problems listed above, the design is going to meet the finger touch interface, and play to the advantages of touch screen’s operation, mining the update operation on the existing basis.
