Landmark-Based Indoor Positioning for Visually Impaired Individuals.
Position localization is essential for visually impaired individuals to live independently. Comparing with outdoor environment in which the global positioning system (GPS) can be utilized, indoor positioning is more difficult due to the absence of the GPS signal and complex or unfamiliar building structure. In this paper, a novel landmark-based assistive system is presented for indoor positioning. Our preliminary tests in several buildings indicate that this system can provide accurate indoor location information.
