It studies the people-oriented of user interface design，and increases the degree of user interface design of human nature. By collating the people-oriented user interface design related literature material， sorting out human-oriented research significance of user interface design， it carries on the comprehensive analysis combined with the market to the requirement of the humanized user interface design， to develop a new type of user interface design， and in the heart of the design of the concept of people-oriented throughout， to ensure that the designed user interface design is to meet human demands. Machine interface design is no longer just meet the use of human to machine the most simple， but will people died as a result of engineering into consideration. People as the user interface of the pilot and the user， only people as the core part of the user interface design， to improve the level of the entire user interface design， only the user interface design based on people-oriented is the most meet the requirements of the modern society.
