User Interface Design

• Hansens 71 Classic
• User Engineering Principles for Interactive
  Systems
• Consider Alternatives
• Prototype Early
• Prototype Often Test Early
• Test Often
• Fail Early Fail Often

3
Iterative Design

• Task
• Artifacts
• We present a model - the so-called task artifact
  cycle - which integrates the development of a
  system being in use into the software lifecycle.
  The basic assumption of the model is, that the
  actual use of a system may considerably differ
  from the original design. This has to be taken
  into consideration in maintenance and
  reengineering. In particular, the monitoring of
  this development process is an important basis
  for maintainability.

User Interface Design

• Important Points!!!
• KNOW THY USER
• TASK ANALYSIS

5
Class Approach to UI Design Process

• Work in Teams
• Go through Design Process from Start to finish
• Four Phase Projects
• Task analysis and user definition
• Sketch out three alternative design
• Based on feedback from Class, TA, Instructor
  User
• Select one prototype
• Define and carry out Usability tests on the
  prototype

• Emphasize User Centered design and that the User
  may see the task in unique ways and vary
  different ways than the designer
