SINS_AR: An Efficient Smart Indoor Navigation System Based on Augmented Reality

With the rapid growth of technology in smart city networks, navigation inside complex buildings is difficult to navigate within such structures. Since the indoor Global Positioning System (GPS) works within an ultra-high radio frequency range, thick walls can negatively affect the quality of signals. The lack of GPS signals and line of sight with orbiting satellites makes navigation more challenging than in outdoor environments. Radiofrequency (RF) signals, Assisted GPS, and sensor-based solutions are used for tracking users in indoor environments, but they have some issues. This paper proposes the Smart Indoor Navigation System Using Augmented Reality (SINS_AR). It provides a solution for this challenge using available and accessible resources. It is used to get the best solution for indoor environments. When implementing the proposed system, a shop within a shopping mall, a specific room in a hotel, or a lecture room in a university can be easily located, providing the users with visual assistance that is reasonably accurate through their smartphones to reach the desired location. SINS_AR system is inspired by augmented reality and 2-D Visual markers. Several visual markers are placed in the complex building structure that when scanned using the application, arrows displayed on the screen lead the users to their destination. The application allows the users to choose their desired destination and also allows them to change their destination in between.
