Non-Intuitive Button Names

• Selected names did not match terms from the
  users vocabulary
• For example Button named Learn To Read Music
  originally named Learning Mode
• Violated Heuristic 2 Match between system and
  the real world

Added Welcome Screen

• It wasnt clear what state the program would
  start in when we did our heuristic evaluation.
• Added a welcome screen that asks the user to
  choose a mode when the program starts.
• Violated Heuristic 1 Visibility of system status

17
No Help System

• In the original design there was no help system.
• Added tool-tips, help menu, and a tutorial
  system.
• Violated Heuristic 10 Help and documentation

18
Added Standard Windows Menus

• Originally we only used buttons in the interface.
  If users didnt recognize icons, they had no
  options.
• Added a menu system which was consistent with
  standard windows menus.
• Violated heuristic 4,6 Consistency and
  standards, and Recognition rather than recall
