In recent ten years, is the vigorous development of human-computer interaction towards natural interaction ten years, there is no doubt that the computer is one of the greatest human invention, its role in the rapid development from the scientific computing tools for information processing and interactive tools, human-computer interaction technology changes played a leading role in the development of computer technology, marked by the mouse of the graphical user interface, to a standard command and computer interactive mode of the command line interface, graphical user interface provides the ordinary people and the computer convenient interactive tools and methods, into the family, let the computer from the laboratory into the office, with the development of touch screen technology, the graphical user interface of the mouse replaced by fingers natural directions, mobile phones become more easy to use portable handheld tools, less reliance on the manipulation of the tool, development and use of cost less natural interaction technology, has always been the pursuit of human-computer interaction research, in the past ten years, with the progress of cognitive and computing technology, natural interaction technology innovation emerge in endlessly, and can be quickly applied to new products, "MIT technology review summarizes and comments on the breakthrough in the field of human-computer interaction technology, the breakthrough technology is divided into three categories: support the natural action of sensing technology, a new type of terminal face to wear, and based on the speech recognition dialogue interaction, the technology break through the influence on the development of human-computer interaction,
