Wharton’s four questions for user-centered HCI

Tale of two tutorials

4 questions for a cognitive walkthrough:
  • How do users know their goal is attainable?
  • How do users know what to do?
  • How will users know they have done the right thing?
  • How will users know they have attained their goal?
Now this may come as something of a surprise if you are primarily involved in HCI, but these questions are profound to software and web site developers since most will never have considered user interaction in this way
