             questionnaire to answer the 10 items that make up   evaluation,  and  the  walkability  value  with
             the  walking  environment  by  the  5-point  method   objectivity added  was  calculated using  the  weight

             animation  which  was  recorded  by  using  the   importance of each evaluation item answered by a 9-
             omnidirectional camera (RICOH THETA V) at 12     point  method.  In  the  questionnaire,  the  responses
             selected  sections  (Zones)  by  wearing  the  head   were got from 4 people who have more than a certain
             mounted  display  (HMD).  To  avoid  influence  the   level of knowledge about the walking environment.
