Test Measures

● Errors / confusions

● How long users spent watching interpreter videos

● Time to complete complex task

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
