In recent times, indoor establishments such as shopping malls, office buildings and even faculties within schools have become larger in size and increasingly difficult to navigate, which has led to much time lost before reaching the destination. This project aims to supplement an Indoor Navigation System that will be able to implement new locations in its database through the utilization of both variances in geo-magnetism in the locations, as well as Wi-Fi signatures of the surrounding areas. Through a central server, each map in any given location will only need to be created and mapped once. Following that, users may subsequently obtain the maps created prior for use in navigation. The application will be tested by multiple clients in the same location. By introducing Wi-Fi signatures in addition to the existing gyroscope and magnetic data into the existing application, this project aims to significantly increase accuracy and turnabout rate in the usage of both the map creation and localization functions. It also aims to increase usability through improving upon the user interface and display. The results generated by the project and application were believed to be satisfactory in terms of improving upon the accuracy of localization, as well as the map-building algorithm. The user interface has also been reworked to be more easily navigable and intuitive.
