Chap. 4 - User Centred Design

1. Interaction design

   • with the use of digital tangible and intangible resulting in intervention
   • A desireable interaction is a result of good design and user understanding

2. why is it important?

   • affect product acceptance and success as user are involved in the product design and development
   • satisfy user with more efficient and user friendly experience
   • increase brand loyalty such as frequent visit to website

3. Context of use

   • automation
   • support
   • informing
   • case study - from problem to solution (papermocking to prototype)

4. Chalking up UCD

   • User & task
     • - understand that user have different capabilities (refer CHAPTER 3)
   • Product usage
     • focus on learning and ease of use
     • type
       • formative - involve evaluating a product or services during design and development with the goal of detecting and eliminating usability problem
       • summative - usability evaluation of complete or near complete design under realistic condition that can be used to determine if the design meet the specific measureable performance
   • Iterative design
     • involve the use of prototype - small scale model of the end product

5. Design tools

   • Scenario
     • Type
       • Goal or task-based
         • state only what user want to do
         • don't include any information on how user would complete the scenario
         • useful in helping to define your site architecture
       • Elaborated
         • give more story details
         • give deeper understanding of user and user's characteristic that may hinder of interaction
       • Full Scale Task
         • similar to use case
         • include the step to accomplish the task
         • can describe the step you plan to set up
     • What to consider
       • Who is the user? -PERSONA
       • Why does user come to this site? -what motivate user t come to the site and expectation upon arrival

       • How can user achieve the goal? -identifying the various possibilities and potential barrier
   • Storyboard
     • Requirement
       • paper, pen, to sketch initial concept
       • list of requirement from requirement analysis
       • navigation chart- which page link with each other, number of types of pages
     • Type
       • Traditional
         • frames with the sketch of what on screen with text underneath
       • Scored
         • style applicable to multimedia presentation/ dynamic design; motion effect, animation, sound
       • Text
         • what happening on screen but describe only using text

6. bad design

   • information overload
   • implication
     • user satisfaction dwindles
     • cause death
     • user task become inefficient
   • information clueless

7. meaning

   • -an iterative process whose goal is the development of usable system achieved through involvement of potential user in system deisgn
