Augmented reality: an advantageous option for complex training and maintenance operations in aeronautic related processes

The purpose of this article is to present the comparison between three different methodologies for the transfer of knowledge of complex operations in aeronautical processes that are related to maintenance and training. The first of them is the use of the Traditional Teaching Techniques that uses manuals and printed instructions to perform an assembly task; the second one, is the use of audiovisual tools to give more information to operators; and finally, the use of an Augmented Reality (AR) application to achieve the same goal with the enhancing of real environment with virtual content. We developed an AR application that operates in a regular laptop with stable results and provides useful information to the user during the 4 hours of training; also basic statistical analysis was done to compare the results of our AR application.
