AI-Driven Augmented Reality Based Smart Campus Navigation System

The campus environment in universities includes many blocks laboratories offices hostels libraries and other facilities spread across different areas which makes navigation difficult for students visitors and staff. The existing methods such as signboards printed maps and verbal directions do not provide proper support and users often struggle to find the correct location. The absence of real time guidance creates confusion especially during busy periods like admissions examinations and events where many people move at the same time. The difficulty increases when users are not familiar with the campus layout and this leads to time loss and frustration. The need for a simple reliable and easily accessible navigation system becomes very important in such situations. The proposed system is an AR based smart campus navigation solution that works through a mobile browser without the need for any application installation. The system uses GPS and device sensors to continuously track user position and direction and provides accurate navigation support. The A star algorithm is used to calculate the shortest path between the current location and the destination and this improves navigation efficiency. The guidance is shown using augmented reality arrows on the camera view which makes directions easy to understand and follow. The system also includes an AI chatbot for user queries voice guidance for hands free navigation and crowd prediction to avoid busy areas. The Firebase database is used to provide real time information such as lab availability staff details and event updates. The system provides a complete and user friendly solution for campus navigation.
