A Spatial Comparison of Tool-Free Assembly Domes and Gers Using 360-Degree Video

Abstract

This study aimed to analyze and compare the spatial qualities of traditional Mongolian ger and dome structures. A total of 51 Mongolian participants aged between 18 and 60 were presented with 360-degree video scenarios of six circular room layouts and asked to evaluate and compare the spatial comfort of each scenario. The scenarios were categorized into three groups of furniture layouts: empty, traditional, and modern spaces. The evaluation included closed questions on a 4-point Likert-type scale and open-ended questions about users’ perceptions of ger and dome designs. The comfort factors of the ger and dome structures, including space, daylight, and comfort, were compared using a paired-sample t-test. The study revealed that round structures were significantly affected by daylight, which impacted the space and comfort of the rooms. Consequently, 73.6% of the participants preferred dome-shaped structures for all layouts. Additionally, the responses highlighted the potential benefits of incorporating windows into round structural designs to enhance their spatial dimensions and interior layouts. Furthermore, the open-ended questionnaire responses suggested that the tool-free assembly method used in ger structures could be a sustainable approach for dome structures. This study highlights the importance of daylight in the design of round structures.
