Description

Technical Field

[0002] As an electronic product designed for children, storytelling machines play an important role in children's growth. They usually focus on rich and diverse story resources and aim to promote children's language development, imagination cultivation and cognitive ability through storytelling. Early storytelling machines had relatively simple functions and could only play pre-recorded story audio. Children could only passively receive information and lacked interactivity. With the continuous advancement of technology, some storytelling machines have begun to have simple interactive functions, such as pressing specific buttons to play different stories and adjust the volume, but these interactions are still relatively limited and cannot deeply meet the diverse needs of children in the process of learning and entertainment. In modern educational concepts, emphasis is placed on children's active participation and personalized experience in the learning process. However, the story content of story machines in existing technologies is relatively fixed and cannot be flexibly adjusted according to children's interests and learning progress. The interactive links lack depth and are difficult to stimulate children's thinking ability and creativity.
