By dividing the book into five (5) chapters, the author is able to clearly examine Graphic User Interface’s (GUIs). All the chapters of the book are coherent and not isolated or independent in topic content. He proposes incorporating fundamental principles for industrial and domestic designs and their concept to the Graphic user interface design. These principles are broadened through levels increasing from the most theoretical to practical using examples of various graphic user interface implementation on a windowing platform such as in Windows; the Apple Mackintosh (Mac), Motif and other X-Windows based systems. A GUI designer team should possess relevant skills such as Graphics design, System Analysis, Cognitive and Task Engineering skills. I. Fundamental principles of design: the first principle states ‘simple tasks deserve simple interfaces’ while the second principles similarly states that ‘complex tasks demand guidance and elucidation’. The ability to differentiate between complex and simple task is easily acquired by learning from feedbacks or experiences of users. Using the Microsoft Word version 6.0 which has undergone considerable revision as a case study, the author concludes that the certain factors such as Visibility, Feedback, and Mapping & Affordances as not totally disjoint components of design but highlights them as the elements of design.
