Since ancient times, navigation has been a fundamental need for individuals, becoming even more central with the development of Global Positioning System (GPS), as well as other indoor localization techniques. Though they effectively represent landmarks for modern society, not all the navigation systems provide accessibility to people who cannot access smartphones, such as blind and visually impaired subjects. In fact, for those people, navigating is a significant challenge, which demands for reliable and efficient navigational aids in terms of sensitivity and resolution for precise guidance. Thus, this thesis fills this gap by developing an innovative electronic system that is based on Near Field Communication (NFC) technology, integrating a reader mounted on the tip of a walking stick with passive tags strategically placed along predefined paths.
