One of the most important problems in teleoperation of heavy machinery is that the work efficiency of teleoperation is lower than half that of a typical boarding operation. This difference is primarily caused by operators' difficulty in creating mental representations (i.e., cognitive maps) of work sites. Operators have two opportunities to acquire information, namely before work and during work, because the introduction of teleoperation requires about one week. Therefore, we have developed a view system to be used before work to provide environmental information concerning work sites on the basis of human spatial cognition. Cognitive maps can be built by acquiring knowledge from two perspectives—the survey perspective and the route perspective. We display an external view from any viewpoint to acquire knowledge from a survey perspective and a view from an operator's viewpoint, which can be modified by the operator's intention to acquire knowledge from the route perspective. Experimental results using a simulator suggested that a proposed view system could help operators acquire cognitive maps, which may lead to a decrease in task time, the number of stops, and the moving distance and an increase in speed during grasping.

允许远程操作员从调查和路线角度预先获取空间知识的视图系统的基本框架

重型机械遥操作最重要的问题之一是遥操作的工作效率低于典型登车作业的一半。这种差异主要是由于操作员难以创建工作场所的心理表征（即认知地图）。运营商有两种获取信息的机会，即工作前和工作中，因为远程操作的引入需要一周左右的时间。因此，我们开发了一个视图系统，用于在工作之前使用，以基于人类空间认知提供有关工作场所的环境信息。认知地图可以通过从调查视角和路线视角两个角度获取知识来构建。我们从任何角度显示外部视图，以从调查的角度获取知识，从操作员的角度显示视图，可以根据操作员从路线角度获取知识的意图进行修改。使用模拟器的实验结果表明，所提出的视图系统可以帮助操作员获取认知地图，这可能会导致任务时间、停止次数和移动距离的减少以及抓取过程中速度的增加。
