Cognitive load evaluation of outfitting AR visual information

To align with the new era trend of paperless and intelligent outfitting in the ship-building industry and enhance the digital level of shipyard manufacturing, Augmented Reality (AR) is being increasingly applied in large-scale production processes. However, when designing AR visualization schemes, human factors are often overlooked. To better assess the mental impact on users, a method for evaluating AR visualization schemes based on the Cognitive Load Theory is proposed. First, we introduce several indexes for assessing cognitive load. Then, we construct a cognitive load assessment model based on the indexes. Finally, we design a validation experiment and verify the effectiveness of the evaluation model by collecting users' subjective evaluation data.
