------------------- Interaction design term ------------------ physicist development and use specialized Terminology for physics. These terms are not only used to describe common processes or things, they also affect how we think about these things. How do scientists express problems, relations, or discovery to other scientists? Technical terminology is the cornerstone of each science, whether it is spider research or printing machine. Computer industry is no exception. We have a rich and complex language to describe subtle fields - such as: Concurrency (?), Recursive and compiler. These are actually the term of the engineer. We don't have the same language in the interactive design area. This needs to be changed. We all have heard about the discussion of user-friendly digital products and interfaces. However, when a person says "high efficiency user interface", he refers to code? Still the number of controls? Is it easy to program? Is it easy to learn? Or is it easy to use? Of course, such words can generate integration in the human brain of wisdom and technology, but the conflict image is not sufficient to successfully interact between the designer and complex digital systems. Interactive Design The world lacks a unified and clear terms system makes the designer 's skills. There is no clear language, we have to communicate more than gestures. There is no clear distiction term, we will accidentally put things in the wrong place, we look down on the point, but it will not work badly. To design a valid digital product, we must have a vocabulary to correctly describe the goals we seek and how we use what tools to achieve goals. Only we have created our own technical language, interacting design can truly become a science, art or craft. Only we develop a way to think about it and talk about and talk about what we have, we can develop successful practices. Unless we can use terminology to express what we do, what we pay attention to, how to judge related success in achieving our goals (?), But not only our role cannot be effectively played, but we have the outside world - software The credibility of engineering and commercial world is also in jeopardy.
