  1. MET CS 405/605 Human Computer Interface Design

  2. Week 4 – Design • Work Reengineering ~ • Realizing the power and efficiency that automation makes possible • Re-engineering the work more to effectively support business goals • Minimizing retraining, maximize efficiency by accommodating human cognitive constraints and capabilities within the context of their actual tasks

  3. Week 4 – Design • Conceptual Design ~ • Process of establishing the underlying organization and structure of a UI • Content Diagram – • Low fidelity prototype • Derive concrete use cases from essential use cases • Identify primary task objectives, attributes and actions • Identify the different “containers” (objects • Link the “containers” to show the flow • Think of the Content Diagram as a preliminary storyboard

  4. Week 4 – Design • Design Guidance & Rational~ • User interface Standards • ISO • Style Guides • Web Style Guide • Customized Style Guides • Exercise – list reasons for using a style guide

  5. Week 4 – Design • Design Principles~ • Simplicity • “Don’t Make Me Think” • Structure • Physical organization • Consistency • Software suite’s vs. “best of breed” • Expected metaphors • Tolerance • Design that helps to preventusers from making a mistake • Recoverability

  6. Week 4 – Design • Accessibility~ • Principles of universal design • “The design of products and environments to be usable by all people, to the greatest extent possible, without the need fro adaptation or specialized design” • W3C Guidelines • Section 508 - government mandate (FAQ)

  7. Week 4 – Design • Design Rational~ • This is what I did, and why • Some time, someone will be revisiting the UI • Others may need to understand your rational, basing new decisions on that • Recording design decisions • Not covered in design guidelines • Not all - particularly important decisions • Notations on other documents (i.e. use cases) • “Issues List”
