Object of this study is to develop a prototype of workstation suitable for three-dimensional space manipulation, 3D workstation. One of the major applications is remote operation of the robot working in dangerous areas ( space robot, nuclear reactor maintenance robot, etc. ). Another application is programing or three-dimensional CAD system. In the future, connecting with advanced computer graphics, the workstation can be expanded to the technology of "Artificial Reality".Firstly, the prototype system which supports three-dimensional remote operation is developed. The system consists of the stereoscopic display, three-dimensional input device ( the 3D mouse ), head-tracking system by image processing, the remote controlled camera heads and manipulator. Secondly, using the system, human hehavior of 3D operation supported by electronics is studied. Based on the study, the following knowledges are obtained.(1) The stereoscopic display system is an effective interface to acquire the remote … More three-dimensional information.(2) Using the system, it is proved that some operators can point an object in the distance correctly and some cannot. Eventually, there are some operators who cannot point it even if they can perceive three-dimensional image. To explain the curious phenomena, concept of the mental model is introduced.(3) It is proved that relationship between the head movement and the camera movement must be designed carefully to control remote camera heads synchronized with movement of operator's head. The coupling coefficient is necessarily introduced. The authors found optimal value of the coupling coefficient by experiments.(4) The author made remote operation system supported by computer graphics. The system can provide numerical information. guide line, graphic manipulator, 3D pop-up-menu and 3D window systme. The system largely improves the efficiency of three-dimensional space manipulation.Finally, by integrating the knowledge, the prototype of 3D workstation is completed. Less

本研究的目的是开发一个适合于三维空间操作的工作站原型--三维工作站。主要应用之一是在危险区域工作的机器人（太空机器人，核反应堆维护机器人等）的远程操作。另一个应用是编程或三维CAD系统。未来，结合先进的计算机图形学，工作站可以扩展到“人工现实”技术。首先，开发了支持三维远程操作的原型系统。该系统由立体显示器、三维输入设备（3D鼠标）、图像处理头部跟踪系统、遥控摄像头和机械手组成。其次，利用该系统，研究了电子技术支持下的三维操作人体健康。在此基础上，本文得出了以下几点认识。(1)立体显示系统是获取远程信息的有效接口 ...更多信息 三维信息。(2)使用该系统，证明了一些操作员可以正确地指向远处的物体，而有些则不能。最终，有一些操作员即使能够感知三维图像也无法指向它。为了解释这些奇怪的现象，引入了心智模型的概念。(3)证明了必须仔细设计头部运动和摄像机运动之间的关系，以控制远程摄像头与操作者头部的运动同步。耦合系数的引入是必要的。通过实验找出了耦合系数的最佳值。(4)作者研制了计算机图形学支持的远程操作系统。该系统可以提供数字信息。引导线、图形操作器、3D弹出菜单和3D窗口系统。最后，通过知识集成，完成了三维工作站的原型系统。少
