Comparison of Video Images and VR Images for Effective Barrier-Free Map Creation
Abstract: Many of the current barrier free maps only add information to the map, and there is the problem: it is difficult to capture the actual situation in real time. As recent research, the places that can confirm road-surface condition increase with 360-degree image (VR image). However, there is still problem that it cannot know the current road-surface condition into image and how it will affect the user when in use. As a method of understanding the situation, we designed a method of confirming with video the current real time situation. Therefore, in this study, we took the manufacture of the barrier-free map for wheelchair users into consideration and we demonstrated traveling by wheelchair with video image and VR image; and examined whether there was a difference in information that could be perceived. As a result, it was found that the VR image was easier to recognize the dangerous part than the video image. However, we could find that subjects who was a user of wheel chair answered that the VR shook more than the actual traveling because it might be difficult to understand the road condition. There were still many problems compared with the actual situation. It seems that image quality is one of the main causes.
