    Study Notes

    Interface Design Principles

    • Key principles for user interface design include layout, content awareness, aesthetics, usage level, consistency, and minimizing user effort.

    Layout Concepts

    • The screen can be divided into three boxes: navigation area (top), status area (bottom), and work area (middle).
    • Information can be presented in multiple areas, and like areas should be grouped together.
    • Areas and information should minimize user movement from one to another, and ideally, areas will remain consistent in size, shape, and placement.

    Content Awareness

    • All interfaces should have titles, and menus should show where you are and where you came from to get there.
    • It should be clear what information is within each area, and fields and field labels should be selected carefully.
    • Use dates and version numbers to aid system users.

    Interface Design Prototyping

    • A mock-up or simulation of screens, forms, or reports can be created using methods such as paper sketches, wireframe diagrams, storyboarding, wireflow diagrams, HTML prototypes, or language prototypes.

    Interface Evaluation Methods

    • Evaluation methods include heuristic evaluation, walkthrough evaluation, interactive evaluation, and formal usability testing.
    • Basic principles of navigation design include assuming users have not read the manual, have not attended training, and do not have external help readily at hand.
    • All controls should be clear and understandable and placed in an intuitive location on the screen.
    • Prevent mistakes, simplify recovery from mistakes, and use consistent grammar order (action-object, object-action).

    Organization of the Interface

    • Define the basic components of the interface and how they work together to provide functionality to users.
    • Use Interface Structure Diagram (ISD) to show how all screens, forms, and reports are related and how users move from one to another.
    • For Web sites, use a site map to show how all the information on the site fits together and to establish the hierarchy of information on the site.

    Defining Standards

    • Clarify decisions on all key interface elements to ensure consistency, including basic common elements, interface metaphor, interface objects, interface actions, interface icons, and interface templates.
