    Adapting Multinomial Dialog for the Elderly
    (10. GI-Workshop "Adaptivität und Benutzermodellierung in interaktiven Softwaresystemen", 2002) Müller, Christian; Wasinger, Rainer
    In this paper, we outline the design of a multimodal interface for a mobile pedestrian navigation system developed within the project COLLATE. The aim of the interface is to adapt to different resource limitations of the user. It takes into account the cognitive load of the user as well as the age. We present an approach on how special acoustic models for elderly speakers can improve speech recognition quality and at the same time provide an information source for user modeling. Three different presentation strategies are presented: unimodal (speech only, graphics only), redundant (speech and graphics providing the same information), and concurrent (minimally overlapped speech and graphics).

    Adapting Spoken and Visual Output for a Pedestrian Navigation System, based on given Situational Statements
    (11. GI-Workshop "Adaptivität und Benutzermodellierung in interaktiven Softwaresystemen", 2003) Wasinger, Rainer; Oliver, Dominika; Heckmann, Dominik; Braun, Bettina; Brandherm, Boris; Stahl, Christoph
    As mobile devices become more and more complex, there is an increasing desire for these devices to adapt to their users. This paper identifies parameters for different input sources (user, device and environment), and the parameters of media output (speech, graphics, sound and text), that may be modified to tailor user presentation in a pedestrian navigation system. We also provide an initial insight into some of the causal relationships between our input and output parameters, with a specific focus on the effects that speech can con- tribute to the presentation of media output.
