AR Indoor Navigation

This paper presents the design and implementation of a precise indoor navigation system based on Augmented Reality (AR) with real-time information integration. The system aims to enhance user positioning and navigation within indoor environments, addressing the limitations of traditional methods. The system utilizes Unity to create a user navigation interface that detects user positions through sensors or camera image processing. A menu-based interface allows users to select destinations, and navigation is facilitated by establishing a NavMesh within Unity’s AI navigation package. Dynamic obstacles, such as simulated crowds and gate blockers, are introduced to enhance realism and adaptability. The research explores the potential of AR to overcome GPS limitations and provide real-time indoor navigation, making it promising for various applications.

I. INTRODUCTION

In today’s urbanized society, mobile phone navigation software has gained remarkable prominence due to its portability and real-time capabilities. However, existing navigation systems face challenges, especially in indoor environments where GPS accuracy is compromised. This limitation impedes users from locating specific places accurately, particularly in densely distributed areas like hospitals. Moreover, traditional navigation systems struggle to provide real-time information about indoor environments, such as crowd density in a mall or exhibits in a museum. Augmented Reality (AR) offers a promising solution by providing more accurate location-based services even in GPS-challenged indoor settings. Cloud services can further enhance information storage and delivery, enabling efficient real-time indoor navigation.
