Research on the optimization of interior design of architectural space considering user perception

This paper integrates the concept of user perception into the presentation of architectural interior spaces. It posits that by employing virtual presentation modes, interior design products are fully demonstrated to users, enhancing their perception of the available information and thereby facilitating the optimization of interior design. The research systematically extracts the influencing factors of user perception by conducting a thorough analysis and synthesis of the literature pertinent to architectural interiors. Additionally, this study combines findings from a questionnaire survey with methods of correlation and regression analysis to further substantiate the identified factors influencing user perception. On this basis, combined with the establishment of a refined model based on real data sources and an indoor modeling method based on tree hierarchy, an indoor 3D virtual scene is constructed with the help of Unity3D software to realize the optimization of architectural space interior design. Overall style of architectural interior space = −2.304 + 0.381*furniture + 0.274*soft furnishing color + 0.205*hard furnishing material + 0.165*lamps + 0.183*hard furnishing color + 0.106*accessories + 0.124*soft furnishing material + 0.115*fabric. Senior and graduate users of higher education had the same attitude towards “personalization” of interior design (both scored 4.33, close to “approved”), while faculty members had the lowest rating (2.6). This study can serve as a guide for the presentation of architectural interiors.
