Abstract: To address the limitations of cene graph structure in augmented asssembly application, a method combined Hierarchy Colored Petri Net(HCPN) with turing machine model was proposed to establish the system model of augmented reality assembly environment. Based on turing machine, the gesture code and pose matrix of virtual hand were taken as input, outputs concrete processing events to update the scene graph. This model was able to record the current internal states of the system and the responses of next operations was given out according to users'inputs. Compared to the method of single collision detection, this model could satisfy the dynamic response requirements of real-time and concurrence of augmented reality assembly system. The prototype system was developed, and the ability of this model's real-time response was verified by analyzing occurrence gragh of the net.
