What's Your Problem?

The smart reader has the function of text orientation reminder. That is, if the book is held reversely, there will be a voice reminder for you. If the reading material is not placed in the front, it will also prompt you to put the reading material correctly through a voice reminder.

First, you need to find an environment with normal light. Then, put on the glasses of the smart reader, place the book vertically in front of the camera of the smart reader at a distance of about half an arm (20 to 40 cm), and make the camera aligned with the center line of the book. After hearing the tinkling sound twice from the smart reader, keep your body stable. After the photo is captured with a click sound, you can move the body normally.
