Study on An Implementation Method of Cooperative Workbench for Integrated Virtual-Real Production

虚拟制作系统实现了对实物的共享和三维操作来设计制作，渲染逼真的三维图像，进行模拟实验等功能。该系统提供了一个基于信息网络技术的虚拟工作环境，使用户能够像在现实世界中工作一样创建“对象”。这是新产品快速开发的迫切需要。另一方面，在概念设计阶段，用双手表现和形成“物体”特征的过程是很重要的。有一些电子手套可以精确地捕捉人类的手部动作，并提供触觉反馈信息。通过使用这些设备，一个以人为本的界面需要被创新，以允许用户，即使他们没有经验，通过他们的手固有的表达能力来创造“对象”。基于上述背景，本项目开展了以下研究课题：(1)虚拟-真实集成生产模型设计并实现了实现虚拟-真实生产的模型。它利用高速网络和虚拟现实技术，使物理上分离的用户在共享的虚拟环境中协同创建一些产品。以烟花设计制作系统为目标应用，实现了从虚拟到真实的无缝生产环境。(2)三维虚拟建模的合理统一界面设计了一种方法，通过一套直观的在现实世界中进行的手工操作来创建三维物体的各种形状。通过使用一副仪表手套，设计并实现了手势界面。(3)协作式反创造性虚拟环境构建了多个原型系统，通过提供手动象形手势输入和浸入式大屏幕输出来实现和评估协作式反创造性虚拟环境。

Virtual production system realizes such functions as sharing and 3D manipulations of objects to design and produce, rendering realistic 3D images and practicing mimic experiments. The system provides a virtual working environment based on the information network technology, enabling users to create the "objects" as if they work in the real world. It is strongly required for quicker development of new products.On the other hand, a process of representing and forming features of the "objects" using their both hands is important at a conceptual design stage. There are some electronic gloves available to precisely capture the human hand motions as well as present tactile feedback information. By using these devices, a human-oriented interface needs to he innovated to allow the users, even if they are inexperienced, to create the "objects" through an inherent expressive power of their hands.Based on the background described above, this project carried out the following research issues :(1) integrated virtual-real production modelA model to realize the virtual-real production is designed and implemented. It allows the physically separated users to cooperatively create some products in a shared virtual environment by using high-speed network and virtual reality technologies. Fireworks design and production system was implemented as a target application to realize a seamless virtual-to-real production environment.(2) Sensible and unified interface for 3D virtual modelingA method is devised to create various shapes of 3D objects by using a set of intuitive bimanual operations as they are performed in the real-world counterpart. A hand gesture interface is designed and implemented by using a pair of instrumented gloves.(3) Cooperative anti creative virtual environmentsSeveral prototype systems are constructed to implement and evaluate the cooperative and creative virtual environments by providing a bimanual pictographic gesture input and an immersible large screen output.
