Annotation-based assistance system for unmanned helicopter with wearable augmented reality environment

In this paper, we introduce an annotation-based assistance system for an unmanned helicopter with a wearable augmented reality environment. In this system, an operator controls the helicopter remotely while watching an annotated view from the helicopter through a head mounted display (HMD) with a laptop PC in a backpack. Annotations assist the operation indicating some conditions of the helicopter and a name of buildings nearby. The position and the attitude of the helicopter is measured by GPS and a gyroscope, and sent to the operator´s PC via a wireless LAN.
