Fundamental development of a safety system for working machinery using vibrotactile information

Abstract

Working machinery used at construction sites, such as plant construction, can cause accidents including overturning, swinging of suspended loads, and damage to the machine body. Because of their large size, these machines can cause extensive damage to the surrounding area when an accident occurs, and new measures are needed to prevent such accidents. We are developing a system that effectively conveys safety information to operators of these machines. In this paper, we report on a vibrotactile safety information system. In addition, a crawler crane simulator using mixed reality technology for validating the safety system is reported.
