Maybe you've seen one of my videos for teachers?
For my series of instructional videos I have a green screen as my background. I then use software to replace the green color with different backgrounds. This chromakey effect allows me to place objects behind and in front of me. I think it helps my videos look slick and puts the focus on my content.
I'm often asked about the set up I use to film my videos. Here's a 360 spherical photo that I've annotated. Feel free to scroll and zoom around to check out my setup.

I took the spherical photo using a Ricoh Theta S camera. Before publishing I brought the image into Keynote where I added the annotations. I saved the image from Keynote as a JPEG and then published using the Theta software.

Your green screen setup does not have to be nearly as fancy as mine. Modern green screen/chromakey software does a pretty good job detecting a green background, even if that background is not well lit and wrinkly. Teachers have shared their setups on Twitter, and they range from very simple to a little more sophisticated...
