Shows how to design screens in a systematic way so that they are easy to understand and support the under interface efficiently. It shows not only how to design an interface, but also how to make a fully functional interface - putting theory into practice and highlighting the problems a designer faces when working in a real-world situation.

Designing the user interface is a key part in the development of any computer system. The designer needs to ensure that the system has adequate usability - it must do what is required and be easy to use. This book shows you how to design the user interface in a systematic and practical way. It bridges the gap between traditional programming perspectives, which often see the user interface as an afterthought, and human-computer interaction approaches, which are more user-centric but give little guidance on screen design and system development. Features Uses the Virtual Window Method to define the right screens and transform them into a full user interface. Illustrates the method with several complex applications. Shows how user interface design relates to systems development and object-oriented approaches. Unique structure of the text makes it ideal for undergraduate students, IT conversion course students and professional courses.

Why is it that some computing systems appear simple and intuitive to use, while others confuse the users trying to work with them? For some software designers the interface is still seen as an add-on when the rest of the program has been written while human-computer interaction specialists consider programming the final task after numerous interface prototypes have been designed and evaluated. This book bridges the gap between the communities by showing how to design screens in a systematic way so that they are easy to understand and support the user interface efficiently. To do so, it draws on experience from programmers as well as usability specialists. Rather than just showing the reader how to design an interface, the book details how to actually make a fully functional interface putting theory into practice and showing the problems a designer faces when working in a real-world situation.
