This lecture demonstrates how to share written exercises on paper via Zoom using a smartphone fixed on a handmade stand. The instructor explains the setup process, including joining a Zoom meeting with a computer and smartphone, adjusting the camera angle, and stabilizing the phone over the paper. Tips are provided to improve the setup, such as using hardcover comic books for stability and ensuring the camera focuses correctly while writing. The lecture concludes with a reminder to remove the hand after writing for a clear image.
