“I'm Looking for a Book with a Big Watermelon and Many Small Ants”: An Exploratory Study on a Visualized Search System for Preschoolers' Picture Book Search

This paper introduces the development process of a preschool children oriented visualized picture book search system—a picture book search system designed specifically for children and their parents. This study involves a thorough literature review and a field investigation to gain insights into the actual needs of children. Besides, it provides an efficient picture book search service by designing a child-friendly interface and integrating advanced search technology. The study employs heuristic evaluation and multiple performance indicators to ensure the system's high recall, precision and user experience. The system helps to promote the cultivation of children's reading interest and the improvement of reading ability, and will be implemented in libraries.
