Abstract
Restoration work following a sediment disaster or volcano disaster may be executed in extremely dangerous places. Construction in such dangerous places can be executed safely if it can be done using construction equipment that can be operated remotely while observing camera images. Construction using such remote control type construction machinery is called “unmanned construction”, and it has been carried out more than 150 sites in disaster prone Japan. It is said that unmanned construction is generally low efficiency construction so an improvement of efficiency have been needed.
If an operator good at unmanned construction and an operator NOT good at unmanned construction exist, it is possible to distinguish operator degree of achievement easily by investigating the characteristic of both operator. And, if we select only a suitable operator and dispatch them to the construction site, it is possible to improve construction efficiency of the unmanned construction site.
So in this study, first, we distinguished both operator by the experiment on test field. Next, the characteristic survey of both operators are done using the eye-tracking camera. Finally, we suggested the method for distinguishing the degree of achievement of the operator easily and for selecting a suitable operator for unmanned construction.
