As soon as you receive this email:

  • Disable any notifications and close any other apps that might reveal sensitive information (passwords, personal conversations, etc.). The conferencing tool we’ll use will record everything on your screen.

Prepping for your session:

  • Make sure you have a headset with a built-in microphone plugged into your Android device. You can join the session in speaker mode, but a microphone will help reduce noise.
  • We’re going to be chatting with you using the Participate App. Follow this link to install the app on your Apple device - it will let me see your screen, record your front-facing camera, and voice.
  • Close any other apps, websites, and notifications with sensitive info like passwords etc.
  • From your device, follow this link to check you're on a strong internet connection. We recommend at least 5Mbps available both for uploading and downloading.

When you're ready to begin:

  1. There will not be a "moderator" and you will be completing the test in your own time, by yourself. It's important that we can hear and understand you, as we won't be able to ask questions during the test. Please speak aloud throughout the study so we can gather your thoughts and perspectives.
  2. Open up this link: [SelfTest Link] on your iOS device
  3. Read the message and tap "Participate".
  4. Connect your headset if you haven’t already, and tap "Next"
  5. Enter your name and email address and tap "Next"

    NOTE: If you prefer anonymity, instruct Participants to enter their name as P1, 2,... and their email can simply be email@email.com

  6. When asked to "Allow Notifications" switch the toggle button to green and tap "Allow" and then "Next"
  7. When asked to “Turn on your camera”, tap "Ok" and then "Next"
  8. Follow these steps to share your screen and turn on your microphone.
  9. On the “Using Bubble” screen, slide the yellow hand as instructed, and tap the hand to start your session
  10. It's important that we can hear and understand you during your session, as we won't be able to ask questions. Remember to think out loud throughout the session, saying what you’re trying to do, what you expect to see, and if things aren’t working as expected
  11. Whenever you need to access the Instructions, tap the yellow hand
  12. If you’d like to pause the recording at any point, access the Instructions screen and tap "Pause". Tap "Resume" to continue.
  13. When you’re ready to end your session, tap the red button (or red bar) at the very top of your screen. Tap “Stop”, then tap “End session” to reconfirm.

Please let me know if you have any questions. I look forward to chatting with you!
