Matters needing attention of tablet computer participating in online re-examination.
Pay attention when using tablet computer to participate in online re-examination. It is recommended to put the tablet computer in a fixed place. Don't always hold the tablet with your hands, your hands will shake and the lens will shake, so find a tablet bracket and a good angle. In addition, the distance from the camera should also be prepared. You can try more and find the right distance. If you hold the tablet near you, the teacher will see a big head on the screen. If you are too far away from the camera, you can't see clearly and the portrait will become smaller.
