Method for comprehensively corresponding and searching functions of electronic appliance and the corresponding device components

There are provided an easy and fast setting method for the functions of electronic appliance, and the corresponding hardware components including an input unit, a CPU, and a display screen. The functional menu is selected from the first layer of interface by using interface variation to progressively approach the interface of the object function until reaching the interface including all the object functions. The present invention is characterized in that the interface representing the functional menu includes several to dozens of functional contents illustrated by texts and/or graphs for being selected and set. Particularly, it is able to use a nine-palace square to further vary the interface by expanding the total number of functions included in the interface based on the multiple of 9, thereby performing function refinement and function of approaching object. With the present invention, generally, it is able to easily and quickly set functions or input characters by only two or three keys. The present method can be applied in a mobile phone for connecting to the Internet, Chinese character communication, and multiple electronic appliances and mechanical and electrical products, so as to obtain excellent functional applications.
