- 91. Who REALLY areyour Users/Stakeholders? •Not as obvious as you think: — those who interact directly with the product — those who manage direct users — those who receive output from the product — those who make the purchasing decision — those who use competitor’s products •Three categories of user (Eason, 1987): — primary: frequent hands-on — secondary: occasional or via someone else — tertiary: affected by its introduction, or will influence its purchase

- 104. How can wequickly prototype interactive experiences with little or no coding?
- 105. Why Prototype? ▪ Quickvisual design ▪ Capture key interactions ▪ Focus on user experience ▪ Communicate design ideas ▪ “Learn by doing/experiencing”
- 106.
- 107. Typical Development Steps ▪Sketching ▪ Storyboards ▪ UI Mockups ▪ Interaction Flows ▪ Video Prototypes ▪ Interactive Prototypes ▪ Final Native Application Increased Fidelity & Interactivity
- 108. Paper Prototyping (LowFidelity) Quick and simple means of sketching interfaces Use office materials Easier to criticize, quick to change Creative process (develop in team) Can also use for usability test (focus on interaction flow) Used a lot to test out concepts before real design begins.

- 113. What is evaluation? •Evaluationis concerned with gathering data about the usability of a design or product by a specified group of users for a particular activity within a specified environment or work context
- 114. When to evaluate? •Once the product has been developed • pros : rapid development, small evaluation cost • cons : rectifying problems • During design and development • pros : find and rectify problems early • cons : higher evaluation cost, longer development design implementationevaluation redesign & reimplementation design implementation
- 115. Four evaluation paradigms •‘quickand dirty’ •usability testing (lab studies) •field studies •predictive evaluation
- 116. Quick and dirty •‘quick & dirty’ evaluation: informal feedback from users or consultants to confirm that their ideas are in-line with users’ needs and are liked. • Quick & dirty evaluations are done any time. • Emphasis is on fast input to the design process rather than carefully documented findings.
- 117. Formal Usability Testing •Recording typical users’ performance on typical tasks in controlled settings. Field observations may be used. • As the users perform these tasks they are watched & recorded on video & their key presses are logged. • This data is used to calculate performance times, errors & help explain why the users did what they did. • User satisfaction questionnaires & interviews are used to elicit users’ opinions.
- 118.
- 119. Field/Ethnographic Studies • Fieldstudies are done in natural settings • The aim is to understand what users do naturally and how technology impacts them. • In product design field studies can be used to: - identify opportunities for new technology - determine design requirements - decide how to introduce new technology - evaluate technology in use.
- 120. Predictive Evaluation • Expertsapply their knowledge of typical users, often guided by heuristics, to predict usability problems. • Can involve theoretically based models. • A key feature of predictive evaluation is that users need not be present • Relatively quick and inexpensive
- 121. Characteristics of approaches Usability testing Field studies Predictive Usersdo task natural not involved Location controlled natural anywhere When prototype early prototype Data quantitative qualitative problems Feed back measures & errors descriptions problems Type applied naturalistic expert
