Augmented Reality (AR) in museums and art galleries can support decolonisation discussions and engage young diverse audiences. This study explores involving young people in co-designing decolonisation practices, however, there is little research on involving young people in the decolonisation debate through personalising museum experiences based on their points of view. We investigated the potential of AR through a low-fidelity prototype, simulating AR worlds to foster inclusive narratives. Our collaboration with a local cultural institution involved a user study with participants interacting with a fictitious scenario, design values, contextualised information, and interaction cards. Observing our co-design process, we discuss how a AR can facilitate community-led discussions and preferred experiences.
