This present study combines augmented reality and interactive multimedia for the construction of a learning system that offers educational knowledge on butterfly metamorphosis, as we call it ARButterfly. The main purpose of designing this learning platform is to apply AR technology to produce innovative interactive learning models that are both fun and educational, creating an enriched learning experience through multimedia. With this platform, learners control the AR markers and are presented with life-like 3D objects to learn about the life cycle of butterflies. In addition, learners are given the opportunity to further observe the ecological interactions between butterflies and flowers or plants in this virtual setting. Our findings show the platform is capable of boosting students’ learning interests and improving their learning effectiveness.
