abstract = {Navigation applications are becoming increasingly complex, since
databases and features are rapidly growing. Navigation databases include a growing
number of points of interest (POI) and a more precise resolution at the street, crossroad
and house number level. Human-Machine Interfaces (HMI) such as Speech
Dialog Systems (SDS) need to be designed in order to allow comfortable access to
data with as little driver distraction as possible. We discuss how the user can find the
intended data in such a large database? Current approaches require browsing the
hierarchical database structure through categories and sub-categories, such as
restaurant and vegetarian. This paper presents a new interface that utilizes a contextfree
keyword search, and relies on a hierarchy of categories only for disambiguation
purposes. This allows a user who does not completely know the hierarchy to find a
destination by simply saying it. The user does not even have to know the precise
name of the destination, since the proposed method generates wording variants by
decomposing the name and recombining its parts. After presenting the new
interaction design and dialog requirements, we derive a dialog system architecture
which we implemented to fulfill these requirements. A short pre-evaluation indicates
that users prefer the new interaction method to the interaction of the S class series
model, because of its increased comfort, ease of use, general appeal, and in particular because of its voice control interface.},
