Simple Task
As a concertgoer, find a concert you would like to attend.
Looking for:● Login● Search and select concert● Functionality of home and menu buttons

Participants Zina, Julia, Sam, Austin,](https://reader034.vdocument.in/reader034/viewer/2022042605/5f4a90a24d62fa12ea7bba55/html5/thumbnails/10.jpg)
Medium Task
As a concertgoer, vote on your favorite interpreter submission for a concert you want to attend.
Looking for:● The voting feature● Interaction with the interpreter submissions● Design and usability of the events page

Complex Task
As an interpreter, upload a video submission for an event you would like to interpret at.Looking for:● Login● Interpreter functionality● Design and usability of the event screen● Uploading and submitting interpretation

Test Measures
● Errors / confusions
● How long users spent watching interpreter videos
● Time to complete complex task

Participants Zina, Julia, Sam, Austin,](https://reader034.vdocument.in/reader034/viewer/2022042605/5f4a90a24d62fa12ea7bba55/html5/thumbnails/13.jpg)
Results: Simple Task
Errors / confusions:
● Want a search bar for events
● Confused that menu button goes to the sign in page
● Liked scrolling through list of events, wished for
Indication that the tab could expand

Results: Medium Task
Time watching submissions:
● Zina: 10s + 11s + 13s (watched all 3)
● Julia: didn’t watch interpreter videos
● Sam: 1m + 20s (watched 2 of 3)
● Toni: 5s + 10s (watched 2 of 3)
Errors/confusions:
● Voting confirmation
● Video fast forward

Results: Complex Task
Time to complete task:
● Time varied greatly based on confusion with selecting
track - varied from 20s to 2m
Errors / confusions:
● Expected there to be a recording when selecting play
● Option to upload (from Youtube) or record
● Confused that a specific track had to be selected to
get to upload screen - no visual indication

Takeaways from Testing
Make the tasks not as similar
UI for voting and uploading needs additional clarification
Allow a dedicated upload button at the top, rather than navigating to it
Allow users to navigate video playback more easily

Discussion: Changes in Interface
From interview with ADA Coachella:
● Fulfilling a need: concert networks
● They need to find certified interpreters in areas where they have upcoming events, and a way to asses interpreters in order to pick the best one for the event.

Discussion: Changes in Interface
From the user tests:
● Search bar for events
● Better voting UI (notified that voted)
● Clarify and change the way that interpreters upload and submit video
● Better way to fast forward in interpretation submission
