초록

This study aims to examine how changes in the Green View Ratio, defined as the visible proportion of plant elements within an observer’s field of view, influence emotional image perception and visual preference in indoor office environments with green wall-based settings. To this end, visual stimuli of an office space were developed using SketchUp and Enscape, with the Green View Ratio systematically adjusted from 0% to 50% at 10% intervals. The Green View Ratio was calculated based on the proportion of plant areas relative to the total image area while maintaining consistent spatial conditions across all stimuli. Twenty-five participants majoring in horticultural design and floral design evaluated visual preference and ten emotional image adjectives using a seven-point scale. The collected data were analyzed using descriptive statistics, correlation analysis, and multiple regression analysis. The results indicated that the relationship between the Green View Ratio and visual preference was non-linear, with visual preference reaching its highest level at a moderate Green View Ratio, particularly around 20%. Correlation analysis showed that visual preference was most strongly and positively associated with the emotional image adjective “balanced,” whereas “oppressive” exhibited a significant negative association. Multiple regression analysis further identified “balanced,” “oppressive,” and “natural” as key predictors of visual preference. In addition, higher Green View Ratio levels increased perceptions of visual congestion and complexity, indicating changes in emotional image perception. These findings suggest that visual preference in office environments is influenced less by the quantitative increase of visible plant elements themselves than by perceived emotional images associated with changes in the Green View Ratio. Therefore, the Green View Ratio should be interpreted not merely as a physical proportion of visible plant elements, but as a perceptual visual indicator related to emotional image perception and visual preference, providing practical implications for the design and planning of indoor workspace environments.
