As one of the earliest attempts to apply immersive technology in environmental communication, this design research project tries to answer the following research question: how do we communicate the connections between food-related behaviors and environmental impacts through immersive storytelling? During the project, an immersive story called "Trik’s' Party" for dome shows and a journey map of an immersive visitor experience are created. These design outcomes and this paper are built on the knowledge of scientific findings, communication methods, content creations, and service design. To support the creation process, new sketching, storyboarding and prototyping methods were developed for dome content creations. The core message of this paper is that effective environmental communication is not just about informing the public about facts and data from scientific studies. It is also about giving individuals and communities the knowledge, tools and spaces to develop a vision of their own future. Immersive storytelling is one of the methods for creating these spaces. It has a large potential to raise public empathy with other people and their future-self when the long-term and abstract impacts of the environmental problems become more visible and comprehensible in an imaginary space.
