1, sensory mobilization, increase interest in activities.

In children's book retrieval, the interface design is mainly based on children's perspective, which can fully stimulate children's sensory activities, create a relaxed and happy activity atmosphere, and children can actively participate in library games. Under the coordination of sensory functions, autonomous activities will be more vivid and inspiring, and children will get more interesting activity experiences.

2, independent operation, improve children's participation.

In the autonomous reading activities in the library scene, children can manage books independently, or use the function of voice input to search for books they want to read independently, which can improve their enthusiasm for participation. In the activities, children can explore, discover and adjust independently, which truly reflects their subjectivity.

3, human-computer interaction, to stimulate children's desire to explore.

In the design of retrieval system, there are typical characteristics of human-computer interaction, as well as the coordination and interaction between human and computer. In operation, children can send out various instructions by touching the tablet computer, and complete tasks such as searching and borrowing with their hands and brains, which can not only improve the application ability of information technology, but also stimulate children's curiosity and desire to explore.

Children's retrieval system can provide timely support for children according to their different levels by using instant voice prompts or video demonstrations, and create a broader learning environment.

4. Reproduce the scene to realize children's self-regulation.

After the integration of information technology and autonomous activities, the time and space restrictions of activities have been broken, and the connection with life has become closer. In the simulated library scene, children need to operate the retrieval system by themselves, and the activity environment is very similar to that of the real library, which can let children experience the process of book borrowing personally and let them know how to make their learning activities more standardized.
