Issues Identified During Cognitive Walk-through for Participant Home Page

Navigation:
  • Step links may not “read” as clickable links to new users.

  • Directions to “begin with step 1” may result in users not reviewing rest of home page.

  • Event reminders are in an awkward location well below the “main steps”; may not be used.

Data retrieval:
  • When confidentiality setting is changed, there is no sense of completion for user—display does not indicate change has been acted on.

Speed:
  • Roll-over graphics take too long to download over some modem connections.

Failure:
  • Session time-out is too short for the reading and discussion that often needs to take place.

Information display:
  • Text used for “roll-over” content is too small.

  • Text describing event reminders is too wordy.

  • “Conditions covered” and “How recommendations are made” lack prominence on the page.
