Briefing
KaJaMi Participant Briefing
Thank you for taking the time to help us test the prototype of our system.
You will be acting as the “user”, our goal is not to test you, but to test our system and find flaws or inconsistencies that will improve the final implementation.
One person from our group will act as a “computer” who will control the experiment and provide tasks that we would like you to perform using the interface.
The other group members will act as “observers”, and will be taking notes on the experiment.
We will be asking you to perform tasks that relate to your current music director duties, but using our interface instead of what you are normally used to. At a high level these tasks will include importing digital music, previewing music and getting CMJ reporting data. We ask that you do not ask interface related questions during the test itself (as this will better help us find faults in our interface) but we can answer anything after the test is complete.
Thanks and have fun!
Scenario Tasks
Scenario |
Task |
---|---|
Imagine you are a music director, Lana, and you wish to upload some albums to the digital library via the KaJaM! interface |
Open KaJaM! and log into the system |
You have downloaded 2 albums onto your computer: Starmarker.zip and KaJaM.zip and wish to import them to the library |
Import Starmarker.zip and KaJaM.zip into the digital library |
While KaJaM.zip is importing, you wish to preview one of the tracks |
Preview (play) a track in the KaJaM album |
The track from the KaJaM album sounds familiar, and you quickly realize you have already imported the album and don't need it again |
Delete the currently importing KaJaM album |
The Starmarker.zip file finishes importing, and you wish to make sure all the track details are correct |
Inspect track details* |
You find incorrect and incomplete track details you want to fix |
Edit track details to reflect the correct information** |
You wish to approve the album to officially file it in the digital library |
Approve the album |
Before you leave, you wish to complete College Media Journal reporting for the month |
Take a look at the reporting data in the digital library |
You notice the reporting data is displaying _the Blue Dot _genre, but you want to look at "Electronica/RPM" |
Filter the reporting data to show only "Electronica/RPM" |
Now all reporting data is on "Electronica/RPM" only, but it is not sorted by play count in the last month |
Sort the reporting data by play count in the last month, in descending order |
Everything looks good, but you still want to make adjustments to the reports based on physical CD play count before submitting them |
Export the reporting data to Excel file format for further editing |
Now that you are all done, you wish to go home |
Done! |
*The album contains tracks with pre-tagged information, but some are incorrect or incomplete:

Learnability
|
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). |
