项目摘要

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.

虚拟生产系统实现了对设计生产对象的共享和三维操作、真实感三维图像的绘制和模拟实验等功能。该系统基于信息网络技术，提供了一个虚拟的工作环境，使用户能够像在真实的世界中工作一样创建“对象”。另一方面，在概念设计阶段，用双手表现和形成“物体”的特征的过程也很重要。有一些电子手套可以精确地捕捉人手的动作，并提供触觉反馈信息。基于上述背景，本项目开展了以下研究工作：（1）虚实一体化生产模型设计并实现了一个实现虚实一体化生产的模型。它利用高速网络和虚拟现实技术，允许物理上分离的用户在一个共享的虚拟环境中合作创造一些产品。烟花设计和生产系统作为一个目标应用程序，实现了一个无缝的虚拟到真实的生产环境。(2)一种用于3D虚拟建模的合理和统一的界面设计了一种方法，通过使用一组直观的双手操作来创建各种形状的3D对象，因为它们在现实世界中执行对应的操作。设计并实现了一个使用仪表手套的手势接口。(3)通过提供一个双手象形手势输入和一个沉浸式大屏幕输出，构建了几个原型系统来实现和评估合作和创造性的虚拟环境。
