Design of Paper Book Oriented Augmented Reality Collaborative Annotation System for Science Education

Abstract

The authors designed a kind of augmented reality annotation system based on network knowledge collaboration for primary science education to expand the cognitive effect. Various types of annotations such as text, images, videos, links, 3D models, etc. can be added to the corresponding position of the paper book by multi-user and multi-device through the system. And the annotation contents could be retrieved in AR mode by other users. The connotation and dimension of scientific knowledge could be expanded through concentrating diversified annotations. The system only records the relative position of the annotation on the page by a hand-aided registration, and uploads the location information to the server without infringing the copyright of the book. The system allows users to add links as annotations, through which users could interact with social media and knowledge communities. By using this system, users' ideas could be connected thus promote the flow of knowledge between different types of readers (such as students, parents, and teachers), readers and authors and it is conducive to the exchange and inspiration of ideas, promoting the integration of knowledge and the generation of group wisdom.
