Construction of a Synchronized Multi-Display Augmented Reality Simulation Module for Learning Tidal Effects

In recent years, Augmented Reality (AR) has been widely employed in educational settings. Most instructional ARs developed so far only dubbed a single interactive AR image onto a single object. However, more complicated concept learning may require liking two or more correlated phenomenon. The correlation between the revolution of moon and tidal effects on earth is one of such correlated concepts. In this study, a multi-image instructional AR toolkit was developed that is capable of synchronously illustrating the relation of moon revolution and tidal effects. By rotating the earth-moon physical model, students will be able to view on computer screen the phases of the moon and coordinated tidal effects on earth synchronously. Student's satisfactions on AR operations, screen interfaces, and desire to use the AR toolkit were fare. The results of this study would inspire the development of more innovative AR toolkits for instructional applications.
