Thank you so much Andrea P. for your question about document cameras to teach origami online and all the answers explaining how they used a smartphone instead! I had not thought about that before.
I taught tonight how to fold a model in the GP3 meeting. I used an android OS smartphone as my webcam. This is how I did it: 1. I installed DroidCam both on the smartphone and my Windows OS laptop. Smartphone app: https://play.google.com/store/apps/details?id=com.dev47apps.droidcam&hl=en Windows OS: https://www.dev47apps.com/droidcam/windows/ 2. I followed this steps: https://www.digitalcitizen.life/turn-android-smartphone-webcam-windows 3. I attached the phone to the arm of my desk lamp using a rubber band. The cool thing about that was that I could then use the lamp as a light source for the paper. 4. I connected the smartphone to my laptop through USB. I didn't need to but that way I wouldn't have to worry about the phone's battery. I do have to learn to check the laptop screen every now and then, because sometimes I wasn't placing the paper in the center of the frame. It'll take some getting used to : ) Before DroidCam I tried two other apps but I wasn't able to get them to work: IVcam and IP webcam. Hope this information helps Andrea or anyone else. I'm really thankful with the information you've all shared. Before, I was folding on the air or against a wall, but now I can use this solution for my conference/workshop...
