To compare the differences in narrative power dynamics among directors, actors, and audiences between traditional films and VR films, I conducted in-depth interviews with industry professionals to analyze VR creation mechanisms suitable for immersive storytelling and to explore the demand for storyboard-like tools. Based on the findings, I designed a creation workflow and developed Dreamfly, a collaborative storyboard software, which was iteratively refined through testing. The research revealed that audiences in VR narratives partially assume director and actor roles due to heightened interactivity. I proposed a design framework to enhance narrative interactivity in VR production and formulated a three-layer theory of narrative freedom in VR storytelling. Dreamfly was exhibited at UAL’s “Discover the Next Generation of Creatives.” I led the interview research, software development, testing, and wrote the thesis.
