A Deeper Understanding of the Impact on the Restorative Quality of Green Environments as Related to the Location and Duration of Visual Interaction

This exploratory research aims to examine if the existence of vegetation in indoor environments affects people's attention levels. Also, do those elements receive more visual attention, or do they cause other elements in the space to stand out more visually? During experimental research, 182 residents of a high-rise residential building were randomly assigned to experience one of two versions of their building's lobby as a 3D virtual reality (VR) environment, one with and one without vegetation. Participants completed the Sustained Attention to Response Task (SART) twice, once before experiencing the lobby to establish a baseline of attention and once after, to assess possible improvement. Also, the amount of visual attention that each element received in the environment was calculated through gaze tracking. Results indicated that participants who experienced the lobby with vegetation showed meaningful improvement in their SART score. The gaze tracking heatmaps revealed that vegetation received significantly higher attention than all other elements. The analysis of the data demonstrated that those who gained the highest scores paid the highest amount of visual attention to vegetation. These findings suggest a positive relationship between the location and duration of visual attention and attention restoration level and that vegetation capturing non-voluntary attention may be among the major factors that positively impact attention restoration.
