Applying maintenance simulation using virtual mockup in product design phase enables maintainability test before prototyping physical products, and it is expected to reduce product development costs. The simulation results can be reused as contents of service manuals and RAM (Reliability, Availability, Maintainability) analysis data. Maintenance simulation should provide realistic representation of physical property of virtual product, assembly relation between parts and manipulation process to verify feasibility of product design. The simulation system should be extended to collaborative virtual environment to perform collaborative maintenance procedures. In this paper, the three layered system architecture and the physics based collaborative interaction technique are proposed to extend current maintenance simulation into collaborative virtual environment. The proposed system was implemented as ViMMS (Virtual Mockup Maintenance Simulation system), and compared with case study results of VADE (Virtual Assembly Design Environment). As a result, the ViMMS encompassed broader range of maintenance tasks by using physics based collaborative interaction technique.

In this paper, we present the virtual dancing studio for distributed virtual environment. In this system, geographically distributed user shares the virtual dancing hall and interacts with each other. The participating object can be a graphical avatar or a live video stream. It allows the coexistence of graphic objects and real images in the shared virtual space. One of the main technical challenges in developing the distributed virtual environment is to handle excessive network traffic. In an effort to effectively reduce the network traffic, we propose a scheme to adjust the QoS of each object with respect to the distance from the observer in the virtual space. The server maintains the QoS vector for each client's shared space and controls the packet traffic to individual clients based on its QoS vectors. We develop a proto-type virtual dancing environment. Java based development enables the client to be platform independent. The result of experiment shows that the adoption of hierarchical QoS management significantly reduces the overall network traffic.

Today, 3D cyber space with advancements of 3D technique is changing into a social space. As such, the users want to make social relationships, the impression that one leaves in 3D cyber space has become more important. This study will advance impression dimensions in 3D cyber space that formed each impression dimensions in pre-study with cyber space based on web sites. As this study analyzes the characteristic elements of 3D cyber space which are differentiated with other platform, it has theoretical value to support theory about personal relationship in3D cyber spaces. Then it will be a supporting theory for next study about intercultural and social phenomena in changeable 3D cyber space as advancement of technique.

For popularization of virtual reality hardwares, VR sickness come from latency is huge problem. To reduce latency, most of the HMDs use cable for video transmission. However, cable causes spatial limitation that disturb user experience. For maximize user's immersion, wireless video transmission system is necessary. Unfortunately, wireless video transmission's latency is much longer than cable's latency. Prediction algorithms may reduce latency but cause jittering effect as a side effect. This paper experiment how jittering effect affects VR sickness. The result of experiment shows jittering effect make vr sickness worse. Future research about prediction algorithm should consider both prediction error and jittering effect.

As for the implementation technology of virtual space, the experience method becomes multifunctional and it recognizes movement, sound, temperature and pressure and is expanding to the studies on the interaction possible intelligent interaction technology field between contents and users. The virtual reality technology is being studied to apply the 3D graphic technology and physical phenomena to virtual space to increase the sense of reality and use hardware devices to the virtual environment to increase immersive experience. The production of interactive contents about the virtual underwater environment needs bidirectional interface technology to connect hardware devices and ocean contents in order to increase the sense of a user to increase the sense of immersion. In this study, it tried to express the virtual underwater environment with the sense of actuality and reality from the analysis of the environmental factors according to changes in depth of water and from the application of the normalized underwater physical laws. Also it was to develop sensory contents having to experience the skin scuba without directly entering the water by connecting a sensory simulator about the skin scuba with the virtual underwater environment.
