I teach computer science, but I may be an anomaly because my primary mode of teaching is "chalk talking" where I will write on the blackboard instead of use powerpoints (you might find more chalk talkers in physics and maths). I feel that it provides better pacing for the students.

My primary use case for this right now would be the fact that I have to teach in person and online at the same time. If one of my students gets covid, they have to quarantine for 2 weeks while I continue lecturing in person. To support them, I have to record my lectures all by myself. Back in the day, it used to be that if you wanted to record your lectures, we had dedicated staff to set up a camera and manage that. Now, everyone has to record their lectures, and there just isn't the personnel to handle this, so we're on our own. Therefore, if I could control my lectures from the chalkboard as I'm talking, it would really be beneficial.

Personally our semester is starting now and I've settled on all of my teaching tools for now, but I'll be keeping track of your progress for sure!
