SunMap+: An intelligent location-based virtual indoor navigation system using augmented reality

In today's modern era, with the advent of technology many people rely on GPS systems to find a destination. However, locating a destination within the confines of an indoor environment is still a challenge as GPS signals do not work indoors, and most people still resort to the conventional method of referring to a physical floor plan or directory. This paper sets to present a mobile software application that uses a visual recognition and pedestrian dead reckoning (PDR) system to create an interactive indoor navigation system using augmented reality (AR). In order to provide an intelligent and context-sensitive navigation platform, data from smartphone sensors are utilised to enable the navigation system to work in an indoor environment. These sensors include using the accelerometer, compass and camera - sensors which already exist in today's mobile devices. Using these technologies, a prototype for an Android application called SunMap+ has been developed to showcase the possibilities of indoor navigation using AR in the test environment of Sunway University campus.
