  1. Models, Metaphor, Paradigms Dr. Dania Bilal IS 588 Spring 2008

  2. Understanding and conceptualizing interaction • Good interaction is based on a clear understanding of • What • Why • How • Benefits • Time and money saving

  3. Problem space • Understanding nature of problem space to be designed • Conceptualize what, why, and how you will create the space • Think about how the design will support users

  4. Understanding problem space • Clarify usability and user experience goals to solve problem space • Make assumptions and claims Class Activity • Scenario: There is a need to develop an open source browser. Think through why such a tool will be useful? • What are your assumptions? (think of what’s wrong with existing browser and how creating an opn source one will solve the problems) • Highlight problematic concerns to identify ideas to be reworked with the new browser

  5. Conceptual model • Is a description of the proposed design • Made • Integrated ideas and concepts about • What should system do? • How should system operate/behave? • How should system look like? • Can system be understood by intended users?

  6. Developing conceptual models • Envision proposed system based on user needs identified • Think: what will users be doing? • Decide on modes of interaction • Identify nature of user activities to support • Identify style of interaction to incorporate in proposed system

  7. Developing conceptual models • Think of concrete solutions • Flesh-out: • explore possible design solutions • Evaluate good and bad about each solution • Adopt best solution • Always have alternative solution

  8. Types of conceptual models • Models based on activities • Models based on objects

  9. Models based on activities • Instructing • Conversing • Manipulating and navigating • Exploring and browsing

  10. Models based on objects • Focus on way an object is used in a particular context • Often based on an analogy or physical objects in the real-world • Students to give examples????

  11. Interface metaphors • Based on conceptual models • Intend to explain something unfamiliar/hard to understand by combining familiar knowledge that is easy to understand Class activity: Use a browser and identify the functions employed that are based on familiar knowledge.

  12. Interaction paradigms We will cover this topic next week along with Understanding Users
