Exploring the interface design of assisting children to find books in the library using smartwatches

Ever-evolving technologies allow modern libraries to introduce multiple digital devices to enable readers to more easily find their desired books. However, the cognitive abilities of children might bring about incorrect use of these devices. Therefore, it is imperative that libraries pursue innovative service such as smart book-finding specifically designed for children to accommodate their needs. In this study we employed expert interviews and current product analysis to examine the informational architecture, graphical user interface and interaction over smaller interfaces, thus formulating guidelines for the design of smaller interfaces. We also designed a book-finding user interface and navigation flow of the smartwatch interface based on the proposed guidelines. These will be applied in children's libraries to enable young readers to complete book-finding tasks with the aid a smartwatch. This development is of great value to children's libraries and serves as reference for smaller interface design.
