Evaluating a User Interface Design
  • Evaluation without users (Inspection method)
    • Heuristic Evaluation
    • Other simple inspection guides for novices
  • Evaluation with users (also known as user studies)
    • Usability testing
heuristic evaluation
Heuristic Evaluation
  • Evaluation method without users
  • Fast and easy to carry out
  • Heuristics are “rules of thumb” for good design
  • Heuristic evaluation involves inspection of an information system through the “lens” of each heuristic in an agreed-upon set of heuristics
what heuristics
What Heuristics?
  • Visibility of system status
  • Match between system and the real world
  • User control and freedom
  • Consistency and standards
  • Error prevention
  • Recognition rather than recall
  • Flexibility and efficiency of use
  • Aesthetic and minimalist design
  • Help users recognize, diagnose, and recover from errors
  • Help and documentation
slide11
1. Visibility of system status
  • The system should always keep users informed about what is going on, through appropriate feedback within reasonable time.

2. Match between system and the real world

  • The system should speak the users' language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. Follow real-world conventions, making information appear in a natural and logical order.
slide12
3. User control and freedom
  • Users often choose system functions by mistake and will need a clearly marked "emergency exit" to leave the unwanted state without having to go through an extended dialogue. Support undo and redo.

4. Consistency and standards

  • Users should not have to wonder whether different words, situations, or actions mean the same thing. Follow platform conventions.
slide13
5. Error prevention
  • Even better than good error messages is a careful design which prevents a problem from occurring in the first place.

6. Recognition rather than recall

  • Make objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate.
slide14
7. Flexibility and efficiency of use
  • Accelerators -- unseen by the novice user -- may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions.

8. Aesthetic and minimalist design

  • Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.
slide15
9. Help users recognize, diagnose, and recover from errors
  • Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution.

10. Help and documentation

  • Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused on the user's task, list concrete steps to be carried out, and not be too large.
interactive heuristics checklist
Interactive Heuristics Checklist
  • Interesting idea that the value of different heuristics changes with the application
  • Developer: Catherine Barber
  • http://www.id-book.com/catherb/index.htm provides heuristics and a template so that you can evaluate different kinds of systems. More information about this is provided in the interactivities section of the id-book.com website.

considerations on evaluation
Considerations on Evaluation
  • Use different web browsers

user testing
User testing
  • Goals & questions focus on how well users perform tasks with the product
  • Major part of usability testing
  • Focus is on time to complete task & number & type of errors
  • User satisfaction questionnaires provide data about users’ opinions
usability testing
Usability testing
  • Usability testing involves recording typical users’ performance on typical tasks in controlled settings. Field observations may also 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, identify errors & help explain why the users did what they did.
  • User satisfaction questionnaires & interviews are used to elicit users’ opinions.
measurement plan
Measurement Plan
  • What do you need to measure?
    • Task-based analyses
