A Proposal of Operation Interface for Teleoperated Hydraulic Excavators to Reduce the Cognitive Load Caused by Mental Rotation

Abstract

In the Japanese construction industry, there is a need to improve productivity per capita due to problems such as a declining working population and an aging population. Therefore, the development of teleoperated hydraulic excavators is being promoted. However, the work efficiency of teleoperated hydraulic excavators may decrease. One of the reasons is that it is difficult to see the surrounding environment, and the introduction of a bird’s-eye view is being considered to solve this problem. However, work efficiency may decrease due to the influence of mental rotation. The purpose of this study is to develop an interface for a teleoperated hydraulic excavator that can reduce the cognitive load caused by mental rotation. As a result of this verification, it was confirmed that the operation time was significantly reduced under specific conditions. In addition, there was no significant difference in the Sense of Agency.
