This paper presents a new travel aid to increase the independent mobility of blind and elderly travellers. This aid builds on the technologies of geographical information systems (GIS) and the Global Positioning System (GPS). The MoBIC Travel Aid (MoTA) consists of two interrelated components: the MoBIC Pre-journey System (MoPS) to assist users in planning journeys and the MoBIC Outdoor System (MoODS) to execute these plans by providing users with orientation and navigation assistance during journeys. The MoBIC travel aid is complementary to primary mobility aids such as the long cane or guide dog. Results of a study of user requirements, the user interface designs, and the first field trial, currently being conducted in Berlin, are presented.
