Abstract
Because of its ability to display information recorded in space, Augmented Reality is used in procedural learning. However, some authors argue that it may increase users' mental effort by requiring constant shifts in focus of attention between real and virtual content. The objective is to recognize the presence of cognitive load and mental effort when context changes occur during the use of augmented reality in procedural learning tasks, particularly in the participant's peri-personal space. An experiment was conducted to assess subjective cognitive load and mental effort during procedural learning activities for human knee surface anatomy. Subjective measures based on self-reports were combined with objective measures based on pupillometry and eye tracking. The learning activity was evaluated in 34 participants who had no prior experience with the activity. The overall findings revealed that the Subjective Cognitive Load and eye tracking measures differ significantly between treatments. The pupillometry measurement, on the other hand, revealed no differences.
