Kurashiki Viewer: Qualitative Evaluations Of Architectural Spaces Inside Virtual Reality

Taro Narahara New Jersey Institute of Technology

This paper discusses how virtual reality (VR) environments can be employed as a data collection tool beyond visualization and representation tools through a simple experiment in a VR space and speculates about its potential applications. Using a VR model that runs on a web browser based on an existing historic town in Japan called Kurashiki, the experiment asked 30 recruited participants to freely walk around and leave ratings on a 5-point scale on any buildings or objects appealing to them. Our system can display points of interest of multiple participants using heatmaps superimposed on a map that can help users visually understand statistical preferences among them. Our goal is to provide a quantitative means for qualitative values of architectural and urban spaces, making such data more shareable. We intended to show that such a platform could help multiple stakeholders reach better consensuses and possibly collect training datasets for machine learning models that could extract features related to the attractiveness in architecture and urban spaces.
