The following information was obtained from a support document at Northwestern University.
1. Before being able to use your cell phone as a document camera, you will need to download the free “ZOOM Cloud Meetings” app.
2. After initiating your Zoom session on a computer, you can log into the session using your cell phone by opening the Zoom app and entering the appropriate meeting ID. It is important that the audio on your cell phone is disconnected to avoid feedback issues. The best way to do this is by selecting the option to not “join audio” before joining the call. If the call was already joined, you can also disconnect the audio by selecting “more” and then selecting “disconnect audio.”
3. To begin sharing your cell phone’s screen, select “share content” and “screen.” Next, select “start broadcast” with Zoom and exit the Zoom app.
4. At this point, the home screen of your cell phone should be shared with your meeting members. To use your cell phone as a makeshift document camera, select the camera app. Open up the photo mode and aim the camera at whatever materials you would like to share with your students.
Notes:
1. It may be useful to prop your phone against something as you show yourself working out problems or writing so that the video connection is more stable.
2. If the screen sharing function on your cell-phone crashes, the app will suggest that you restart your device. If it is possible to do so without disrupting your session, restarting your cell phone and rejoining the Zoom meeting may help with troubleshooting technical difficulties.
