Research on the Interaction Design of AR Picture Books via Usability Test.

In children’s books, picture books account for seventy percent. With the development of information technology, picture book with Augmented Reality (AR) is an emerging application under the influences of digital technologies, which is a new kind of picture book with the auxiliary of games. The AR picture book bases on the children’s cognitive level and the operation of the mobile devices, satisfying their needs of exploring and learning new things. Under the literature review and competitive analysis, we exploratively put forward the prototypes of interactive AR picture books, especially for the kids aged from 5 to 8. Furthermore, we designed the usability test on one of our prototypes, Rocket Dream, to better understand the process of interaction design. According to the results, we testify the feasibility of AR picture books as well as figure out some issues in the interaction processes, such as the weak guidance in the interactive operation, incomplete essential information in the interface, as well as the fact that children’s preference of visible interaction and touch operations and they are more sensitive to large objects. Also, we propose potential solutions to these issues in the following parts, which could be useful for the future of AR picture books.
