Effects of visual information on a remote-controlled robot

摘要

To efficiently perform work using a remote-controlled robot, an image display device that allows the operator to verify the working area from a single view is necessary. Furthermore, this device should provide high-resolution images of locations so that the operator can recognize depths in detail. To meet these requirements, conventional three-dimensional image devices used multiple cameras and display screens for the right and left eye. In this study, we developed a camera device using a camera and a display, which can provide a wide-range view while providing high resolution for the central part of images using a mirror. We evaluated the effectiveness and verified that operators can accurately conduct a remote operation in a short period of time; this was possible using high-definition spatial information from a composite screen and continually adapting to changes in the surrounding environment that could be viewed at a wide range. The experiment also revealed that the composite screen ratio can be altered as required.
