AR-Assisted Indoor Navigation for A Multistorey Building

Abstract

This project presents a novel approach to indoor navigation within multistorey buildings using Unity, NavMesh, and line rendering techniques, eliminating the reliance on GPS signals. Traditional GPS-based navigation systems are ineffective indoors due to signal attenuation and multipath effects. To address this limitation, our system utilizes a combination of Unity’s NavMesh for pathfinding and line rendering for visual guidance. The NavMesh is generated to represent the walkable surfaces within the building, allowing for efficient pathfinding algorithms to calculate optimal routes between destinations. Line rendering is employed to visually guide users along these paths, providing intuitive navigation cues without the need for external hardware or sensors. Additionally, the system incorporates features such as waypoint placement, floor selection, and destination highlighting to enhance user experience and facilitate seamless navigation across multiple floors. Through this project, we demonstrate the feasibility and effectiveness of using Unity and NavMesh for indoor navigation, offering a versatile solution for multi-storey buildings where GPS signals are unavailable or unreliable.
