IntroductionChapter 1

Designing software is a knowledge-intensive activity, and the process ofdesigning and implementing the user interface (UI) of a system is noexception. Being involved in the user interface design activities oftenmeans taking on a set of different roles during a software developmentproject, e.g., the systematic engineer, the creative artist or the systems ana-lyst …… 此处隐藏：28973字，全部文档内容请下载后查看。喜欢就下载吧 ……
