Navigation System for the Visually Impaired Based on an Information Server Concept

    Research output: Contribution to conferenceConference articleScientificpeer-review


    NOPPA navigation and guidance system is designed to offer public transport passenger and route information for the visually impaired. It provides an unbroken trip chain for a pedestrian using buses, commuter trains and trams in three neighbour cities' area.The system is based on an information server concept, which has user-centred and task oriented approach for solving informational needs of special user groups. Information server with speech user interface acts as an interpreter between the user and different information databases. Use of commercial information databases and web services ensures that the visually impaired persons get the same up-to-date information than other citizens. This paper also presents concepts and experiences of using public transport real time information in personal navigation systems. The case presented is about using bus real time information to help the visually impaired to get in and leave a bus at the right stop.
