tailieunhanh - Lecture Systems analysis and design methods (7/e): Chapter 17 – Whitten, Bentley

In this chapter you will learn how to design and prototype the user interface for a system. You will know that you’ve mastered user interface design when you can: Distinguish between different types of computer users and design considerations for each, identify several important human engineering factors and guidelines and incorporate them into a design of a user interface, integrate output and input design into an overall user interface that establishes the dialogue between users and computer. | Chapter 17 User Interface Design Chapter 17 – User Interface Design Objectives Distinguish between different types of computer users and design considerations for each. Identify several important human engineering factors and guidelines and incorporate them into a design of a user interface. Integrate output and input design into an overall user interface that establishes the dialogue between users and computer. Understand role of operating systems, web browsers, and other technologies for user interface design. Apply appropriate user interface strategies to an information system. Use a state transition diagram to plan and coordinate a user interface. Describe how prototyping can be used to design a user interface. 17- Chapter 17 – User Interface Design 17- Chapter 17 – User Interface Design System User Classifications Expert User – an experienced computer user Spends considerable time using specific application programs.

Use of a computer is usually considered non-discretionary. In the mainframe computing era, this was called a dedicated user. Novice User – a less experienced computer user Uses computer on a less frequent, or even occasional, basis. Use of a computer may be viewed as discretionary (although this is becoming less and less true). Sometimes called a casual user. 17- Chapter 17 – User Interface Design Interface Problems According to Galitz, the following problems result in confusion, panic, frustration, boredom, misuse, abandonment, and other undesirable consequences. Excessive use of computer jargon and acronyms Nonobvious or less-than-intuitive design Inability to distinguish between alternative actions (“what do I do next?”) Inconsistent problem-solving approaches Design inconsistency 17- Chapter 17 – User Interface Design Commandments of User Interface Design Understand your users and their tasks. Involve the user in interface design. Test the system on actual users. Practice iterative design. 17- Chapter 17 – User Interface .
