Music Director #1

  • User found the drag and drop interface to be intuitive and easily learnable, but isn't familiar with the fact that file start importing as soon as the mouse button is released. Instead, user searched for an "OK" button to start importing officially. This is a tradeoff we made to achieve more efficiency, but sacrifices some safety because the user may inadvertently drop the wrong file on the interface.

Learnability

  • User recognized the play button beside the track right away

Efficiency

  • User's single click on the play button starts playing the track right away
    Safety
  • If user clicked on play accidentally, a pause button appears in place of the play button to stop track

...

  • | Learnability
  • On the user-friendly interface, the user had some trouble locating the trash can because it was placed far away from the user's line of vision
  • On the high-efficiency interface, User quickly found the "X" delete button beside the uploading album
    Efficiency:
  • High-efficiency interface requires very little mouse movement to reach the "X" button, whereas the user has to move the cursor all the way across the screen in the user-friendly version of the interface.
    Safety:
  • User prefers that the user-friendly interface gave a confirmation warning before deleting album

...

  • | Learnability
  • User found the both interfaces to be easy to understand in terms of what information is being displayed
  • Both interfaces lack affordances in terms of what is editable and what isn't, user had to experiment by single clicking on the fields 
    Efficiency
  • User liked how both interfaces showed all the album and track information on one screen
  • User noted the directly editable fields are very convenient
    Safety
  • User noted a mistake in adding the genre can be easily fixed by clicking the "x" beside the genre tag

...

  • | * User was confused about how to "approve" the album on both interfaces because he did not associate approval with the "checkmark" button (learnability issue)
  • Again, a tradeoff was made between efficiency and safety: single click on the "checkmark" button will approve the album immediately (efficiency). User prefers a confirmation message (safety). |
