Abstract: This paper presents a novel application of natural interaction techniques for technical documentation navigation in augmented reality maintenance. The objective is to provide technical information where and when needed in order to reduce the time spent in retrieving procedural data from manuals. The system integrates a video and depth camera for user gesture acquisition, a webcam for marker-based tracking and a see through head mounted display for digital information overlay. We designed a novel hand free gesture-based interface to access technical documentation while performing maintenance tasks. We implemented a specific flexible system to prototype natural interfaces using UML configurable state machines. It supports 2D and 3D content navigation, CAD assembly explosion, real time 3D sectioning and operation browsing. We differentiate the interaction metaphors for 2D documents and 3D CAD models in order to be intuitive and easy to learn. A case study and a user test demonstrated the feasibility and the good acceptance of the presented gesture interface.
