摘 要：This paper demonstrates, with a prototype, one such use case where an indoor positioning system can be made more useful by rendering relevant 3D graphics on the mobile display. It also describes our application development process, right from target user interviews to an interactive high-fidelity prototype development in Android. Localization is achieved by creating a location API simulator and using the orientation sensors in the phone/tablet. Relevant graphical information, determined based on the user’s context and selection, is rendered using OpenGL on top of the live camera stream. User studies indicated that overlaying points of interest on the camera view significantly enhanced the user experience in indoor navigation.
