Abstract
Due to the increased time spent indoors as a consequence of the COVID-19 pandemic, individuals have become more engaged in personalising their indoor environments and actively participating in related decision-making process. This decision-making is influenced by how people perceive spaces, as shaped by their knowledge, characteristics, and experiences. This study aims to explore the dimensions of human perception based on temperament and experience to determine preferred indoor space compositions using mixed-reality technology. Temperament was assessed using the Holland Occupational Themes RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, and Conventional) test, whereas experience was analysed using a theoretical framework incorporating text mining and PageRank centrality. The findings revealed variations in spatial preferences across RIASEC categories: conventional individuals preferred beige, carpet, and PVC flooring, whereas enterprising individuals favoured marble. This study uniquely examines the human perception system and how individuals form and act on memories of indoor spaces.
