Goals

For File Uploader user test we want to consider ease of use for uploading files to Sakai [to start with].  <ac:structured-macro ac:name="excerpt" ac:schema-version="1" ac:macro-id="82b881df-cfdc-430c-867f-841c3e17e568"><ac:parameter ac:name="atlassian-macro-output-type">INLINE</ac:parameter><ac:rich-text-body><p>Research questions/goals include:</p>
<ul>
<li>Do users realize they can upload files?  Do they realize they can upload multiple files?</li>
<li>Are users successful at uploading a file in general?  A single file from their computer?  Multiple files from their computer?</li>
<li>Can a user find a particular file easily?</li>
<li>Do users recognize and understand intuitively how to upload files?</li>
<li>Is pause/resume upload understandable or does this confuse them</li>
<li>Does the user understand that you cannot "cancel" the upload until you first "pause" the upload? Is differentiating between paused and not paused states understandable to users?</li>
<li>Are visual affordances meaningful and helpful to users?</li>
</ul>

Success Criteria

  • 80-90% of users can successfully upload a file from their desktop.

Users

The File Uploader will be used by a wide cross-section of students and faculty in higher educational institutions.  We'd like to include keyboard-only users in the user test if possible (can prototype handle keyboard nav?).

Our access to participants is limited primarily to students over faculty.  We will try and include a few faculty.  We want to test a range of non-technical and more tech savvy students as well as faculty members of the University of Toronto and UC Berkeley.  For our user test with working prototype we will have 5-7 users [combination of students and faculty, but primarily students].

** If doing: For earlier paper-prototyping sessions we will work with a smaller number of participants.

Greeting the User

Hi [user's name].  I'm [your name] with the Fluid team.  Today we are looking for ways to improve the usability of a Fluid component.  Remember we are not testing you.  If you find something difficult to use, chances are that others will as well.  If you feel uncomfortable you can stop at any time during the study.

Please speak all your thoughts aloud as you go through the tasks.  This helps us better understand why you are making certain choices.  The study will take about 45 minutes.  We will answer any questions you have at the end of the study.

Do you have any questions? If not then, let's get started!  <sound enthusiastic>

First we'll need you to sign this Consent Form .

Next we'll need you to complete this brief demographic questionnaire Demographic Questionnaire.  All your information will be kept private.  Your name will not be associated with the results at all.  

Task sheet for upload tasks to be used by facilitator for note taking.

Scenarios

Note: Trying to create scenarios where participants will use the File Upload component without us telling them specifically "to upload a file".

Scenario 0

You are taking an Introduction to Photography class. Your current assignment is to take three pictures demonstrating different types of lighting and share them with the rest of the class for discussion and critique. You found and took several pictures with your digital camera and transfered them to your computer several days ago. You now need to locate those pictures and submit them for the assignment to the class Image Gallery. If you remember correctly, you transferred the pictures to your computer into a folder named Photography101.

Task

Description

Task 1

Upload a file from the Photography101 folder on your desktop

Task 2

Upload the 4 most recent files in Photography101 that were saved today

Task 3

Upload all files in Photography101. <while upload progress is going> You realized that IMG_9409.jpg and IMG_9407.jpg are the wrong files and you didn't intend to upload those to the Photography class site. What would you do?

Task 4

You remembered there are photos you wanted to add to the site from your desktop. You want to add image020, image021, and image025.jpg. What would you do?

Scenario 1

It's the middle of the semester and your group project for Psychology 101 is due in two days.  You are collaborating with several other students.  Each of you has taken a section of the project to work on.  As each team member finishes their section they IM the group to let everyone know their progress. 

Your job on the project team is to take all the sections and combine them into one document and submit to the instructor through your class Sakai site (folder: "final project"). 

The files you need to combine are:
- introduction.doc
- method.doc
- results.doc

The files may be located in any of the following places:
- folder "class project" on the computer's hard drive
- Psychology 101 class work space on Sakai
- Sociology 100 class work space on Sakai

Scenario 2

You are a TA for undergraduate class "Psychology 101" and teach a tutorial/discussion section of 30 students.  You are responsible for lecturing in the tutorial as well as grading the assignments of your 30 students. 

Last week was the course mid term and you have just finished grading all 30 online assignments.  Your feedback remarks for each student are written in a Word document.  You need to get each student's feedback to them on their space on the course Sakai site.  You are hoping to do this for the following three students' feedback.

Student Files:
- Allison_feedback.doc
- Colin_feedback.doc
- Daphne_feedback.doc

Scenario 3

You are an instructor for undergraduate class "Psychology 101" and teach a large lecture of 300 undergraduate students in the Fall term.  There are typically 10 tutorial/discussion sections of 30 students each taught by your TAs.  You have your TAs do the grading of exams and assignments.  It is the Winter term/Fall semester and recently you have been asked by your department chair to offer this course in the summer term/session as an online course.  In preparation for the new online course you have created a separate Sakai site for it and started organizing your lectures and notes by week.

Today you are working on the materials for the new online course for week 3.  You have a lecture in Powerpoint and 2 short assignment descriptions that you have been finalizing.  You have just recruited a few new TAs and want them to familiarize themselves with these materials and so are making the materials available on the new course Sakai site.

Files for TAs to review are:
- lecture_3.ppt
- Assignment_3.doc
- Group_assignment_description.doc

Notes for Test Coordinator

Offering Help during the test

Try not to offer help too soon.  Let the user attempt to upload a file a few times.
* If they ask for help reply with:
** "What do you think you/that would do?"
** "What do you think that means?"

You want to observe whether the user has trouble:
* uploading a file from the computer, another site, or current Sakai site
* is pause/resume upload understandable or does this confuse them
* does the user understand that you cannot "cancel" the upload until you first "pause" the upload, is this confusing
* differentiating between paused and not paused states
* is the wizard layout for the Continue and Cancel buttons confusing? should these two buttons be moved adjacent to each other instead of separated on either side of the panel?

After the Test

Post-test Questionnaire for user participant to fill out.

Uploader User Testing - Round 1 Results

The user testing on the Uploader was carried out in a "quick-and-dirty" fashion. Ten users (5 in Toronto, 5 in Berkeley) were asked to spend less than 30 minutes with us to complete 4 upload tasks.  Below are the results thus far.

Toronto: 

  • All users were able to successfully upload files
  • 3 of 4 users asked if selecting multiple files was possible before being asked to add multiple files. Given the selected users were rather tech-savvy, this demonstrates the users' high expectations.
  • All users acknowledged the list of selected files and proceeded to click on Upload

Berkeley:

  • All users were "wowed" by being able to browse and select multiple files at once.  Even though they didn't expect it, all quickly selected multiple files.
  • While files were uploading, 4 of 4 users chose "browse collections" to return to the image gallery thumbnail view.  They expected the upload to continue "behind the scenes".  There was no feedback that the upload would stop (but that's what happens).  This happened on one to several tasks for each user.
  • One user mentioned it would be nice to see thumbnails in the upload queue.  He said the thumbnail could even get bigger as the user mouses over it.
  • 3 of 4 users said they would not stop the upload in progress to remove files from the queue.  They would wait until all files were uploaded and then remove them from the Gallery.  One user did mention that if she was doing it on her own she  probably would have played around with the pause.
  • 4 out of 4 users didn't immediately notice when the files were done uploading.  For a couple it took prompting for them to realize.  A couple users mentioned that it was pretty subtle.  They expected to be taken back to where they started from (browse images & collections) when the upload was complete.
    • Increase the visibility of the "File Uploaded" message.  How about "Upload Complete" in bold?  There is no reason to grey it out.  Users immediately think greyed out information is irrelevant.
  • The one user that used "remove" in the upload queue said it is too subtle.  She had trouble seeing that the file was actually gone (files name with default camera numbers).  She ended up removing extra files because she didn't think it was removing.
