This paper addresses the use of Augmented Reality
(AR) systems to improve maintenance technicians’ performance
from training stage to daily interventions. The concept of AR born
in industry and since then has being developed by scientists to
fulfill the real demands of operational teams. It will be presented
the most relevant industrial AR projects and their results, as well
as others that significantly contributed for the development of AR
and their implementation on industrial environments, namely the
progress from marker-based systems to model-based systems.
Nowadays, industrial AR systems are not a faraway utopia.
