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

这项研究的目的是开发适用于三维空间操作的工作站的原型，3D工作站。主要应用之一是机器人在危险区域（太空机器人，核反应堆维护机器人等）工作的远程操作。另一个应用程序是编程或三维CAD系统。将来，与先进的计算机图形相连，可以将工作站扩展到“人造现实”的技术。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），通过图像处理，遥控相机头和操纵器组成。其次，使用该系统，研究了由电子支持的3D操作的人类Hehavior。 （1）立体显示系统是获取遥控器的有效接口……更多的三维信息。（2）使用该系统，证明某些操作员可以正确地指出距离的对象，而有些操作员可以指向距离的对象，而有些操作员则不能。最终，有些操作员即使可以感知三维图像，也无法指出它。为了解释好奇的现象，引入了心理模型的概念。（3）证明，必须仔细设计头部移动与摄像机运动之间的关系，以控制与操作员的头部移动同步的远程相机头。需要引入耦合系数。作者通过实验发现了耦合系数的最佳值。（4）作者制作了由计算机图形支持的远程操作系统。该系统可以提供数值信息。导线，图形操纵器，3D弹出窗口和3D窗口系统。该系统在很大程度上可以提高三维空间操纵的效率。在本质上，通过整合知识，3D工作站的原型完成了。较少的
