Abstract

In this paper, we present the design, implementation, and an evaluation of a new augmented reality indoor navigation system developed with Unity. Indoor navigation, however, is difficult for most people because GPS is not available in confined spaces, which necessitates different strategies for accurate positioning and understandable navigation. We present a real-navigational assistive system for indoor environments which utilizes computer vision-based simultaneous localization and mapping (SLAM), inertial measurement units and augmented reality (AR) visualization. To build this system, we relied on Unity's AR Foundation framework, supplemented by custom path-finding algorithms, along with interface components that played out in the 3D space. The system was tested in a multi-story building on a university campus, with 45 users performing navigation tasks of different complexity. Results show an average positioning accuracy of 1.2m, along with a 92% of users successfully arriving at their destination with 4.3/5 score on usability metrics. Our AR approach outperformed current indoor navigation approaches, reducing navigation time by 27% and wayfinding errors by 68%. These developments add to the growing body of work on AR application development, as we overcome critical challenges toward indoor navigation and show how Unity can be used to implement these solutions for practical use in complex 3D indoor spaces.
