Technology of Operations on Devices in a Virtual Aircraft Cabin

Abstract:

This paper focuses on the manual operations on the virtual cabin devices of a flight simulator developed by virtual reality technology. The system consists of the space positioning system, the data glove, the three-dimensional head-mounted display, the left and right eye stereoscopic imaging computers, the space positioning computer, and the main simulation computer. The hand position, attitude, and shape data are measured through the space positioning system and the data glove while the aircraft position and attitude are calculated through the aircraft simulation system. The hand model is represented by the hand position, attitude, rotation angles of fingers, the key points in the hand and the movement directions of these points .The virtual devices are modeled with object-oriented method encapsulating device shapes, operation status, the hand key points and their movement directions that are affective on the device shapes and operation status. The aircraft attitude is overlaid with the hand attitude in order to regard the moving cabin as static. Thus the coordinate transformations are confined to only the hand model and the device models that operation status changed to avoid the large amount of coordinate transformations and reduce the system time consumption. The application result shows that the virtual operation algorithm has a high efficiency, and the operation precision meets the need of system performance.
