If there is only a whole simple equipment like a light built in a simple function around us, neither happening will occur to us nor UID theory will be useful.
But recently equipment supplied to home or office have complicated and various functions, besides become miniaturization. In one word, additional functions in comparison with the limited factor of design is becoming various.
While varied functions give high added value, they cause new problem not only in the stage of design but also in users, and rather raise the problem for use.
This kind of tendency is a new problem causing from the functions of recent electric appliances and is a example of raising problem rather than convenience on functions. Most of users might have experience the decline of operation causing by too many additional functions.
This study considers what kind of factor we need for the design of the interface with rough contents of the method on the interface design, and examines what field of knowledge we need for the design of UID.
