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
  • 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

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

• Learnability
  • User tried to unzip all files first then drag and drop the content directly onto the KaJaM interface
  • Our interface did not make it explicit that users are to drop zip files directly
    
• Efficiency
  • User noted that he will want to drop multiple files at a time
    
• Safety
  • User also noted that there doesn't seem to be a way to cancel a file dropped accidentally

• Learnability
  • User was confused that the right side of the screen was completely blank, and instead clicked on "recently uploaded" tab to look for the tracks within currently uploading album
  • The tabs are not labelled clearly to communicate what it is really for
    
• Efficiency
  • Quickly found the play button to preview each track

• Learnability
  • Found the trash icon quickly due to its red color
  • Trying to kill the progress bar (to stop it from uploading)
  • User wants a feature that allows for stopping the import but not delete it (pause it for now)
  • Want to drag and drop the tracks onto the trash can to delete instead of clicking
    
• Efficiency
  • Had trouble deleting all 3 separate tracks quickly, just deleting one at a time
  • Repetitively delete everything is a concern: no expedient way to delete everything
    
• Safety
  • Don't need confirmation message, especially if it acts like a recycle bin like on Windows
  *

• Learnability:
  • Quickly decided to double click on the song track name, then figured out the single click is better
  • User suggested offering more affordances for single click because he is a "double-click" guy (learnability and efficiency)
  • He got that "Unknown" is the album name rather quickly
  • Don’t know what unknown date is (import date or release date?). Also English styled date is not good
    
• Efficiency
  • What if there are different artists in each album (compilations are very frequent), want the ability to change the artist name for each track versus for the album (efficiency versus customizability)
  • Various artists for the entire album, but separate artist name for each song
  • User wants to potentially change the genre for each track
  • User does not value visual album art as much and prefer to have everything displayed as he considers himself to be a database guy
    
• Safety
  • No issues with safety

• No issues with learnability, efficiency or safety but want to see what he has approved during the current session (want to see what other people have uploaded recently)

Music Director #1

• User found switching modes via the tabbed interface to be easy and intuitive (learnability)
• Single click on another tab switched the mode immediately (efficiency), and user noted he can easily switch back if he accidentally clicked on another tab (safety)

• Learnability
  • User struggled with understanding the "filter" button and what it means - he thought it brings up another "filter"
  window 
  • window&nbsp
• Efficiency
  • User did not like how selecting a genre from the drop down menu did not filter the genres right away
  • Not efficient to require 2 user clicks every time a genre needs to be filtered
• Safety
  • Requires user to confirm genre choice by explicitly clicking on "Filter", but user did not like this

• Learnability
  • User did not know how to sort the rows (no affordances offered to suggest that clicking on the header row sorts it)
  • User noted that having an arrow displayed beside the header would really help to indicate the sort function
• Efficiency:
  • Single click on the head column sorts the table in descending order, second click sorts the table in ascending order. User thought this was convenient
• Safety:
  • User did not know how to "clear" the sort, but eventually just noted that he could just click on another head row to sort by another row instead

• User found the export button very quickly and no troubles with this task (learnability)
• User liked that the file started downloading right away without prompting him to confirm (efficiency versus safety)
