Study of key techniques concerning virtual assembly system for equipment maintenance training

With the application of virtual reality in assembly, a completely new training means can be now used in the equipment maintenance training. The key techniques of virtual assembly system for equipment maintenance training (VASEMT) are introduced from four aspect in this paper. They are the virtual equipment modeling, the vstereo display of virtual environment, the human-computer interaction based on the data glove and 3-D spatial compound collision detection.
