A prototype visual augmented reality AR system, designated AR Mentor, for training maintenance on the U.S. Army Bradley fighting vehicle was developed and tested. The system consists of a compact computer, head worn cameras, microphone, ear-buds and eyewear. A virtual personal assistant provides real-time dialog and reasoning supporting human-like interaction using spoken natural language. Feedback and interaction occurs both verbally and by engaging the AR system to display icons and instructions visually on a monocular optical see-thru display. The inserted visual objects appear as part of the live scene and remain precisely aligned to the equipment. The prototypes potential for training was evaluated in the Ft Benning Bradley Training Divisions introductory training course for Bradley maintainers. Even though the prototypes training capabilities were not optimized, student hands-on learning on two types of maintenance tasks while using the system was still equivalent to learning achieved under normal tutelage of an Army instructor.
