AR-Based Virtual Campus Tour and Information System for Smart Educational Navigation

Abstract

Augmented Reality (AR) is rapidly transforming the way users interact with real-world environments by integrating digital information with physical surroundings. In large educational campuses, navigation and access to essential information remain significant challenges for new students, visitors, and parents due to the limitations of traditional methods such as printed maps, signboards, and guided tours. These approaches often lack interactivity, accuracy, and real-time updates. This paper proposes an AR-Based Virtual Campus Tour and Information System designed to enhance campus navigation and user experience through immersive technologies. The system leverages AR to provide real-time navigation by overlaying contextual digital information, including building details, directions, facilities, and announcements, directly onto the user’s view. Additionally, Virtual Reality (VR) is integrated to enable remote exploration of the campus through interactive 3D environments, offering users a comprehensive understanding of the campus layout before physical visits. The proposed system incorporates advanced image recognition, AR visualization techniques, and 360-degree imaging to ensure accurate and engaging interaction. Furthermore, compatibility with modern VR devices enhances immersion and usability. By combining AR navigation, VR-based virtual tours, and real-time information delivery, the system aims to improve navigation efficiency, accessibility, and overall user satisfaction within educational institutions.

Introduction

The AR-Based Virtual Campus Tour and Information System is a smart platform designed to improve campus navigation and exploration using Augmented Reality (AR), Virtual Reality (VR), and 360-degree imaging technologies. Traditional navigation methods such as maps and signboards are often inadequate for large educational institutions, making it difficult for students, visitors, and parents to navigate campuses efficiently.

The system consists of two main components:

1. AR Navigation Module – Provides real-time navigation through a mobile device by overlaying digital information such as direction arrows, building names, and distance indicators onto the physical environment. It uses image recognition and dynamic updates to guide users accurately.
2. VR Virtual Tour Module – Enables users to remotely explore the campus through immersive 3D virtual environments created from 360-degree campus images. This feature is particularly beneficial for prospective students and visitors who cannot physically visit the campus.

The system is developed using Unity 3D and C# programming and includes modules for user interaction, image recognition, AR navigation, VR tours, and database management. A centralized database stores information about buildings, departments, facilities, and announcements, ensuring users receive accurate and updated information.

Performance evaluation was conducted through 10 test iterations comparing the AR system with traditional navigation methods. Results showed that:

• Average navigation time using traditional methods was 124.3 seconds.
• Average navigation time using the AR system was 67.1 seconds.
• The AR-based system reduced navigation time by approximately 45%, demonstrating improved efficiency and accuracy.

The study concludes that the system significantly enhances user experience by providing real-time guidance, reducing confusion, improving navigation accuracy, and enabling immersive virtual campus exploration. However, challenges such as high processing requirements, device compatibility issues, and variations in indoor tracking accuracy remain. Future enhancements may include AI-based route optimization, indoor positioning systems, and cloud-based real-time updates to further improve functionality and user experience.

Conclusion

This study presents an innovative AR-Based Virtual Campus Tour and Information System that enhances navigation and information accessibility in educational institutions. The system successfully integrates AR, VR, and 360-degree imaging to provide: • Real-time navigation • Immersive virtual tours • Accurate information access Experimental results confirm that the system improves efficiency, reduces navigation time, and enhances user experience. This research highlights the potential of AR and VR technologies in building smart and interactive campus environments.
