Immunology knowledge can be difficult for students to visualize and relate to. To help students better understand specific immunology concepts and increase their learning motivation and engagement, we designed the Immu- nology virtual reality (VR) application. Immunology VR leverages the rich in- teractivity and immersion offered by virtual reality systems to create a highly interactive and narrative-driven immersive VR experience that takes students on an exciting journey inside the human body. In this paper, we describe the design of the Immunology VR experience, focusing on our use of an interactive digital storytelling approach to enable learning.</span></p>
