Having trouble? Let's fix it.

Camera permission denied

  • When prompted, tap "Allow" to give camera access
  • If you accidentally denied, go to your browser settings
  • Look for "Permissions" or "Site Settings"
  • Find this site and enable camera permission
  • Refresh the page after changing settings

Camera already in use

  • Close any other apps or browser tabs using the camera
  • Restart your browser if the issue persists
  • On iOS: Double-tap home button and swipe up on other apps

Camera shows black screen

  • Make sure you are using the rear camera
  • Check if something is covering the camera lens
  • Try restarting your browser
  • On some phones, try in a brighter location

No camera found

  • This app requires a device with a camera
  • Tablets without cameras cannot run this activity
  • Ask a facilitator for a device with a camera

Important

Ask a facilitator for the paper version if technology is not cooperating. It teaches the same concepts and works just as well!

Still stuck? Ask a facilitator for help.
