PERCEPT based interactive wayfinding for visually impaired users in subways

In this paper we introduce a PERCEPT based interactive indoor navigation system that enables the visually impaired users to independently navigate in subway systems. The user carries an Android Smartphone that interacts with the subway environment in which we deploy Near Field Communication tags. Using the navigation instructions generated by PERCEPT system the visually impaired users can successfully navigate to their destination. The system has been deployed in Arlington subway station in Boston and has been successfully tested with visually impaired subjects.
