Communicating environment protection from plastic waste via VR: Effects of realism and spatial presence on risk perception

This study tested the utility of virtual reality technologies in building public awareness of an environmental issue—the growing pollution of plastic waste in oceans. We conducted an experiment to test whether viewing of VR video would produce two anticipated immersive experiences (e.g., perceived realism and spatial presence) in severely polluted oceans, and to further examine their effects on participants’ pro-environmental attitudes with regards to reducing plastic waste. Results showed that VR viewing led to higher perceived realism and spatial presence in comparisons with 2D video and audio-only conditions; perceived realism contributed significantly to pro-environmental attitude, whereas spatial presence did not. The higher the perceived realism, the stronger the pro-environmental attitude. Implications of the findings for using VR technologies for effective environmental communication are discussed.
