We investigate the combination of Augmented Reality (AR) with Intelligent
Tutoring Systems (ITS) to assist with training for manual assembly tasks. Our approach
combines AR graphics with adaptive guidance from the ITS to provide a more effective
learning experience. We have developed a modular software framework for intelligent
AR training systems, and a prototype based on this framework that teaches novice users
how to assemble a computer motherboard. An evaluation found that our intelligent AR
system improved test scores by 25 % and that task performance was 30 % faster
compared to the same AR training system without intelligent support. We conclude that
using an intelligent AR tutor can significantly improve learning compared to more
traditional AR training.
