Storytelling of Collaborative Learning System on Augmented Reality.

As augmented reality technologies offer superior senses of presence and immersion to learners through layers of virtual information over the physical world, much attention has been drawn to this learning medium that creates a new learning environment driven by experiences. And, existing ARbased learning content has just focused on interactions among users and on three-dimensional imaging techniques while the collaborative element has not been taken into account fully. Against the backdrop, a rule- based interactive storytelling element has been introduced to the system that offers a variety of contents at a user's choice so as to draw attention and interests. To verify the effectiveness of such learning system, an experiment was conducted with primary school students who went through a performance assessment of 'Growing Peach Tree'. The experiment proved the learning system effective with a high score of 80.4, which is equivalent to that of debate-based learning.
