Abstract: Augmented reality (AR) in the application of complex equipment maintenance can increase
the information content of maintenance support and the comprehensive capability of maintenance
operation, which improves maintenance support efficiency. Based on the analysis on the typical
state-of-the-art AR prototype system, the feasibility of AR using the complex equipment maintenance is
explored. Meanwhile, the solving method is provided aiming to the critical technology in term of the
AR realization. Furthermore, the previews are forward to the trend of development of AR.

Key words: augmented reality, equipments maintenances, tracking and registering, human-machine
