Augmented reality in the perspective of cognitive load theory.

Augmented Reality (AR) is a technology that enables the incorporation of three-dimensional virtual objects into a real-world environment and allows users to interact with these objects in real-time on the screen. Because of its various advantages, AR is becoming increasingly popular in education settings. Several studies have proven that AR is effectively used in learning, AR encourages students to be more active, more motivated to learn and supports their spatial abilities. However, on the other hand, other studies have revealed that AR is not significantly better than non-AR-based learning settings. Cognitive load theory explains of how human information processing systems occur during the learning process and provides a framework on how to design effective learning to deal with limited human processing systems. By reviewing on some previous relevant studies, this paper discusses AR-based learning from the perspective of cognitive load theory. The review shows that, AR is effectively used in learning when 1) student learn complex material/task or learn new topic/information; 2) AR is well designed; 3) student can operate AR properly; and 4) AR is fostering generative processing. This paper will contribute to the current knowledge of AR utilization, in particular about when AR is effective for use corresponding to the perspective of cognitive load theory. Accordingly, future researchers or AR developers can design more effective AR for promoting student knowledge acquisition. [ABSTRACT FROM AUTHOR]
