摘要

Human being lives in the man-machine-environment system. For throusand years, in order to adapt, reform and utilize the environment human being has made some artificial interface between the man and environemtn so that a system has been set up in which the man, environment and interface are related each other and interdependent one another. These interfaces made by human being are classified into two groups, i.e. software interface and hardware interface. For the former, the examples are language, method, technology etc. The latter is articles for daily life, instrument, equipment etc. The most of hardware interface are engineering products. Obviously it is difficult for human being to live in the world if the man-machine-environemnt system is not perfect.
