Design and Implementation of Learning Content Authoring Framework for Android-Based Three-Dimensional Shape

This study was conducted to create a more tangible educational environment by allowing learners to directly control three-dimensional learning contents through the touch interface of smart devices. Furthermore, because there are limitations to the acquisition and provision of three-dimensional learning contents due to difficulties in producing them, the proposed framework was designed to allow teachers and learners to directly produce and share contents. The proposed framework is based on intuitive XML language and the application was built to enable playback and authoring in Android-installed devices. In addition, a server environment was constructed for contents sharing. The feasibility of the proposed framework was verified through expert evaluation and its potential for utilization of new learning contents was positively evaluated.
