Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent printing, and relates to an interactive paper-based children's intelligent learning reading material and its printing preparation method. Background Art

[0002] Through literacy and reading activities, children achieve the comprehensive ability cultivation process of word recognition and information understanding. The development of children's reading ability is a gradual process, which is of great significance to the development of children's learning, cognitive and social communication abilities, and helps them better adapt to society and acquire knowledge.

[0003] At present, the common children's reading methods mainly include two forms: traditional picture books and modern electronic screens. Picture books can attract children's attention through beautiful pictures and cultivate the interest and habit of reading. However, picture books have obvious deficiencies in interactivity. Children often passively receive information during the reading process, lacking interactive communication with the books, which affects the continuous stimulation of children's learning interest. Compared with picture books, electronic screens (such as tablets, smartphones, etc.) have significant advantages in terms of interactivity. Children can perform real-time interactions with the content on the screen through operations such as touching, clicking, and dragging. This kind of interactivity can better meet children's curiosity and exploration desire, enabling them to gain a sense of achievement in the gamified learning process, and thus improving their learning enthusiasm. However, when staring at the electronic screen for a long time, children's eyes will be stimulated by harmful light such as blue light emitted by the screen, which is harmful to children's eyesight. Summary of the Invention

[0004] To overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide an interactive paper-based children's intelligent learning reading material and its printing preparation method, so as to solve the problems that traditional picture books lack interactivity and electronic screens are harmful to eyesight.
