The adoption of non-linear narrative techniques in storytelling has shown promise in enhancing the educational experience. With this in mind, the book “Chandra-Padma” was designed to cater to the non-linear storytelling experience for children (Lankadari & Rodrigo, 2024). In this context, Augmented Reality (AR) technology can enhance and enrich the traditional experience of reading a non-linear book. However, the dynamic nature of non-linear storytelling presents unique challenges in creating supportive AR applications. Moreover, designing and developing an AR application for children who have no prior experience with AR is also a challenge. Subsequently, the project suggests a model where a physical storyboard-based iterative process allows children to understand the AR concept and enjoy the non-linear story in the physical setting. This child participatory research approach emphasizes smooth transitions from a physical to a digital environment for a nonlinear narrative. After that, these data and insights that emerge during the test time are combined to develop an AR space to give a better storytelling experience for a non-linear story. The primary purpose is to find out the set of functionalities and features derived from this approach in order to build an NNAR (Non-linear Augmented Reality) application in the future. This continuous feedback loop and progressive learning make this model resilient and capable of evolving over time. A pilot test was carried out, particularly in the context of a group of Sri Lankan children (ages 7–14). The paper focuses on a participatory research methodology, involving children in the design and development process. Additionally, this approach provides valuable insights into children’s preferences and behaviors. In addition to augmenting the reading and learning experience, this study will also serve as a model for future designers to develop NNAR storytelling applications focusing on improving user experience with non-linear narratives.
