The objective of this study is to focus on plant arrangement and clarify the effect on intellectual productivity during information processing. First, we evaluated the impression of green visibility in virtual space. From factor analysis, similar evaluations were obtained in real space and virtual space. The psychological evaluation factor was found to be the highest at a green vision rate of 7.9%. Next, four arithmetic operations were performed in the five plant placement spaces. It became clear that the psychological evaluation was high for desks and wall hangings. It was inferred that the arrangement of plants reduced the working time.
