On the way toward interactive assembly planning

The assembly work constitutes a large percentage of the whole process of product manufacturing, assembly process planning is always one of the most difficult problems in manufacturing field. In this paper the authors will introduce a series of human centered thoughts and strategies on solving this problem which are realized in their prototype system. User's intents are captured by both the modalities of hands and eyes; Multiple perceptions and two hand concurrent manipulations are designed to acquire the interaction semantics and to deal with the most difficult cases of assembly; A new assembly model is put forward to support 3D interaction, and the method of using the real design data in the system is also introduced.
