Drawing of operation flowcharts is an effective tool to clarify required or fundamental specifications. They also give various labor- and cost-saving effects such as reduction of design work hours and lowering a program modification rate with respect to usability. Of course, the largest advantage is that they provide a means to explain the effects of a user interface concisely to designing engineers, which leads to successful development of commercial products with good usability. To improve usability, it is desirable that a user interface designer participates in a project from the stage to examine required and fundamental specifications so that he/she can utilize his/her logical thinking methods. The current method to draw flowcharts uses quite a primitive drawing method, because there is no specialized tool available. I am trying to develop a specialized tool for this technique or an add-in tool to an existing application software.
