In an era that is very advanced in technology as today, the Graphical User Interface (GUI) is very necessary in all applications such as navigation application. It is a tool that has been used to navigate people in public places such as airports, shopping centers, hospitals and so forth. However, the development of GUI for Local Positioning System (LPS) especially in indoor navigation is still lacking and inaccurate in term of no shortest routes and audio guidance presented. This study was undertaken to improve this development – which aims to help people to get clear navigation and direction to their navigation inside a building or local area. This study not only provide the navigation by visual but also with audio, where blind people also can use the functions of GUI. The development of GUI and all algorithms are completed by using LabVIEW while the LPS is based on Ultra Wide Band (UWB) technology which can give the accuracy less than 30cm. At meanwhile, the user positioning is calculated through trilateration method. The result shows that the GUI of the system is function properly, where it able to show the shortest routes, distances in meter, and also audio guidance successfully. Several experiments are conducted in a test bed environment which has layout 9m x 12m in order to test the reliability of the system. The experiments are repeated for three times and data collected is analyzed. The result shows that the data obtained is still in one-meter walking boundary (1m acceptable limit) and meaning that the system is reliable.
