This lecture demonstrates how to share written exercises through the Zoom app using a blind tablet (a tablet without a screen) and a laptop. By connecting the tablet to the computer, installing the necessary driver, and launching Zoom, the tablet can function as a mouse on the screen. Within Zoom, you can utilize tools like free draw, various colors, thickness settings, eraser, undo/redo, and clear screen to write exercises. However, there is a challenge in coordinating hand movements on the tablet while looking at the screen, requiring practice to master. Despite the learning curve, this method allows for sharing written exercises effectively using a whiteboard feature.
