Abstract: This research investigates the potential of integrating odor-based stimuli with augmented reality (AR) technology for treating psychological disorders such as PTSD and anxiety. The sense of smell strongly affects the limbic system, which is closely associated with emotional regulation and memory, highlighting its relevance for therapeutic applications. The study reviews the relationship between odor, memory, and emotion from a neuroscientific perspective and evaluates the technical capabilities of existing digital olfactory technologies. Subsequently, an AR-supported olfactory therapy model is designed, and its theoretical framework and process flow are established. The findings indicate that this approach supports neuropsychological mechanisms and may contribute to the development of next-generation therapeutic tools in practical settings. By examining multisensory therapeutic experiences, the research provides an interdisciplinary perspective on olfactory and AR integration and proposes a promising and innovative approach for personalized digital therapies.
