Virtual Reality Greenspaces: Does Level of Immersion Affect Directed Attention Restoration in VR Environments?

Abstract

Research on attention restoration theory has provided consistent results over the years, and exposure to nature has been found to significantly improve and restore directed attention fatigue. However, rapid urbanisation has made it increasingly difficult for human beings to interact with unpolluted nature. Countries such as Singapore began to integrate nature into city planning and into the designs of buildings to help resident satisfaction and well-being. Local studies have had contradictory outcomes; residents report significantly higher restoration and affect towards vertical integrated greeneries, but many would still prefer traditional on-the-ground foliage. Interest in outdoor greenspaces is variable because Singapore’s high heat and humid climate make it uncomfortable to interact with outside nature for prolonged periods. The current study tested alternative modalities that can provide residents with on-the-ground foliage interactions, without the discomfort of being outdoors. Virtual exposures with different levels of immersion (high and low) and types of scenes (nature and urban) were tested for effects on perceived presence, perceived restoration and objective restoration. A total of 120 adult participants completed the study, which revealed that a virtual reality-nature condition provided significantly superior directed attention restoration and higher presence ratings. Immersive tendency did not affect perceived presence; neither did it moderate the relationship between perceived presence and its corresponding perceived restoration.
