However, the latter can be improved by visual cues and the addition of learning activities, such as value-added studies have revealed. The spatial AR type is better compared to see-through AR. However, these results are based on media comparison studies that have been criticized for years. Results and ConclusionsĬompared to other technologies, AR seems to be less cognitively demanding and also leads to higher performance. The results are now reported as a synthesis. A total of 58 studies were identified and analysed using rigorously defined inclusion and exclusion criteria. This study applied the systematic review method. The aim of this study is to systematically analyse previous research on AR and cognitive load, including performance, and thus to be able to contribute to answering the question of the impact of AR on cognitive load when used in learning environments. Previous studies on augmented reality-enriched learning and training indicated conflicting results regarding the cognitive load involved: some authors report that AR can reduce cognitive load, others have shown that AR is perceived as cognitively demanding and can lead to poorer performance.
