People who work in windowless environments often experience negative emotion and a high level of stress, primarily due to the absence of sunlight and isolation from nature environment. In response to this challenge, researchers and designers have created artificial windows to mimic sunlight and window views, the objective is to simulate natural surroundings, providing visual and psychological comfort. This paper analyzes benefits of windows, summarizes prior studies on artificial windows' impact on occupants’ mood and work productivity, scrutinizes experimental design and evaluation methods, reflects the limitations of previous studies on artificial windows experiments, and proposes potential improvements for future research. This study contributes to providing direction for future research, enhancing the science and effectiveness of experimental designs and applications of artificial windows. It also contributes to the optimization of artificial window design for the purpose of creating healthier and more comfortable interior settings, with far-reaching and valuable implications for future architectural and interior design.
