SPEECH-BASED AND MULTIMODAL APPLICATIONS FOR TIMETABLES AND ROUTE NAVIGATION IN PUBLIC TRANSPORT

Mobile devices, such as Smartphone and personal digital assistants, can be used to implement efficient speech-based and multi-modal interfaces. In this paper we present three approaches for mobile public transport information services, such as bus timetables and route guidance. These applications offer varying functionality depending on the devices and modalities used. Some services can be used with regular mobile phones, while other services use GPS information and multimodal inputs to make the interaction moreefficient. The applications are designed with various user groups, such as the visually impaired, in mind, and evaluated with long-term pilot studies and usability tests.
