Design And Implementation Of Asd Children’S Cognitive Education System Based On Unity3d, Xuejing Gu, Kaifeng Zhang, Yucheng Guo, Zhiliang Wang
Journal of System Simulation
Abstract: ASD (autism spectrum disorder) is a broad sense of autism. In order to improve cognitive deficits of children with ASD, promote cognitive generalization in ASD children, an education system was designed using Unity3D. The built-in physical engine of Unity3D was used to create a game environment which conformed to the physical laws of the real world by simulating the effects of gravity, buoyancy and collision. The Agent technology and state machine were used to realize the representation and control of virtual scene. Camera and face detection technology were used to realize facial imitative cognitive training. The preliminary test showed …
Two-Machine Co-Simulation Based On Mobile Augmented Reality, Zhili Zhang, Wang Chao, Long Yong, Shaodi Wang
Two-Machine Co-Simulation Based On Mobile Augmented Reality, Zhili Zhang, Wang Chao, Long Yong, Shaodi Wang
Journal of System Simulation
Abstract: Aiming at the problems that virtual training system was not convenient and was only performed in a single operation at present, a dual-machine collaborative system based on mobile augmented reality was designed. A portable augmented reality system was developed on the Unity3D platform with Tango technology. The photon server and LAN architecture were built on the basis. The client was built on the mobile platform of Lenovo PHAB2 Pro, and the co-simulation on dual-machine was implemented. Resultof the simulation proved the feasibility of combining augmented reality with photon server, and provided a set of practical development solutions for …

Development Of Interactive Simulation Of Dive And Underwater Operation Process Of Jiaolong, Xiaoxi Zhang, Yin Yong, Mincang Liang
Journal of System Simulation
Abstract: In order to solve the problems of difficult implementation and high safety risk in the practical training of deep submarine work at present, the simulation system of dive and underwater operation process of jiaolong is designed based on the virtual reality technology, which is not limited by time and place. The 3D modeling technology is used to construct the 3D model of the key structures such as the jiaolong and the mother ship. A mathematical model of A frame motion is established to simulate the motion process. Human-computer interaction and roaming are achieved by using 3D interactive technology, …
