How old is the point reading machine suitable for children? The point reading machine is mainly aimed at the early education of the baby, so the baby around 3 years old can use it. Basically, you can use it for about half an hour every day, not too long, which is very bad for your eyes.
The point reading pen uses the technology of printing two-dimensional code on books to implant sound files into books. Users can choose the page to read and click on the patterns, characters, numbers and other contents on the page at will. The point reading pen can identify the two-dimensional code on the book through the high-speed camera assembled on the pen head, and read the sound file of the corresponding content, and the recognition accuracy can reach over 99.8%.
The principle of point reading machine is that in the process of making pronunciation files, the "latitude and longitude position" corresponding to the book content is preset for pronunciation files. The user puts the textbook on the tablet of the machine, and points the words, pictures, numbers and other contents on the book with a special pen, and the machine will make corresponding sounds.
