Prototypes of an Automatic Inspection Map Creation System Interlocked with User's Walking and a Large Information Board for Regional Disaster Prevention

Abstract

This paper describes an automatic inspection map creation system that automatically records user's walking trajectories and view images interlocked with user's walking and a large information board that display the inspection map, public information on disasters and tweets from residents for regional disaster prevention. We prototyped them and conducted an experiment for comparing the map creation system with a conventional system. The results show that it allows users to create a map without editing and it is easy to use for novice users. We also conducted an experiment about speed of scroll text and fixation area on the screen of the information board due to differences in height of the screen. The results show a prediction expression of the readable speed based the number on lines and the number of characters and show that the number of fixations on the lower area is significantly lower than the upper area when the screen is located below viewers' eyes.
