Large campus’s navigation becomes a crucial issue nowadays due to its layout complexity and digital services’ diversities. Addressing this challenge, this research focusses on Universiti Teknologi Malaysia and presents a novel campus navigation solution that incorporates location-based Augmented Reality with an Artificial Intelligence chatbot. In contrast to previous AR navigation systems, which rely on static visual markers, and chatbot systems, which provide text-based support, the proposed system links real-time AR guidance with intelligent and context-sensitive handling of inquiries. This dual functionality capability sets the solution apart because users can follow AR-driven directions, ask questions, and receive instant information about campus facilities. The prototype was developed using an Agile-inspired iterative methodology that allows for continuous refinement based on user feedback. Evaluation results show a high degree of user satisfaction: 95% of respondents agreed that the system enhances the clarity of wayfinding, while 70% reported that they feel more confident in navigating a campus independently. The study emphasises the practical impact of using combined AR and AI technologies for campus digitisation by showing that the system can be effective in improving navigation efficiency, reducing reliance on physical signage and human assistance, and making the process more engaging and interactive for new students and visitors. In this work, the authors provide a novel model of a hybrid AR-chatbot navigation that can be used in future initiatives on smart campus development and scalable digital support systems in higher education.
