仮想エスカレータを用いたBroken Escalator現象に関する研究

抄録

The Broken Escalator (BE) phenomenon is a unique experience that people have unnatural feelings, walking behavior or postural changes when stepping onto a broken escalator, although the escalator is completely stopped. It is thought that previous experience of stepping onto a driving escalator modulates human motor control resulting in the BE phenomenon. Thus, several previous studies have suggested that the visual information of an escalator, which includes previous experience, strongly contributes to the BE phenomenon. In the present study, we tested if a virtual escalator displayed on a head-mounted display can induce the BE phenomenon. In details, walking behavior and subjective assessment on the virtual escalator and floor during the experiment were analyzed to reveal the potential of virtual reality to the BE phenomenon.
