    USER INTERFACE DESIGN MODEL


    THE GOLDEN RULES

    1. Place the user in control.


    2. Reduce the user’s memory load.
    3. Make the interface consistent.
    Place the user in control.
    Define interaction modes in a way that does not force a user
    into unnecessary or undesired actions.
    Provide for flexible interaction.
    Allow user interaction to be interruptible and undoable.
    Streamline interaction as skill levels advance and allow the
    interaction to be customized
    Hide technical internals from the casual user.
    Design for direct interaction with objects that appear on the
    screen.
    Reduce the User’s Memory Load
    Reduce demand on short-term memory
    Establish meaningful defaults.
    Define shortcuts that are intuitive.
    The visual layout of the interface should be based on a
    real-world metaphor.
    Disclose information in a progressive fashion.
    Make the Interface Consistent
    Allow the user to put the current task into a meaningful
    context.
    Maintain consistency across a complete product line.
    If past interactive models have created user expectations, do
    not make changes unless there is a compelling reason to do
    so.
    USER INTERFACE DESIGN PROCESS
    INTERFACE ANALYSIS AND MODELLING
    User analysis
    • Are users trained professionals, technicians, clerical, or manufacturing
    workers?
    • What level of formal education does the average user have?
    • Are the users capable of learning from written materials or have they
    expressed a desire for classroom training?
    Task Analysis and Modeling (Elaboration ,Workflow,Representation)
    • What tasks and subtasks will be performed as the user does the work?
    • What specific problem domain objects will the user manipulate as work is
    performed?
    • What is the sequence of work tasks—the workflow?
    Analysis of Display Content
    • Is proper on-screen identification assigned to all content?
    • If a large report is to be presented, how should it be partitioned for ease
    of understanding?
    INTERFACE DESIGN

    • Applying Interface Design Steps (Objects,actions)


    • User Interface Design Patterns
    • Design Issues (response time, error handling)
    INTERFACE CONSTRUCTION
    Interface Design Principles and Guidelines
    • Communication &Consistency
    • Latency Reduction
    • Track State
    Interface Design Workflow
    • Develop a rough sketch
    • Map user objectives into specific interface actions.
    • Storyboard screen images for each interface action.
    • Develop a procedural & behavioral representation
    INTERFACE VALIDATION
