C Mueller, Rainer Wasinger · eCite Digital Repository (University of Tasmania) · 2002
In this paper, we outline the design of a multimodal interface for amobile pedestrian navigation system developed within the projectCOLLATE. The aim of the interface is to adapt to different resourcelimitations of the user. It takes into account the cognitive load ofthe user as well as the age. We present an approach on how specialacoustic models for elderly speakers can improve speech recognitionquality and at the same time provide an information source foruser modeling. Three different presentation strategies are presented:unimodal (speech only, graphics only), redundant (speech andgraphics providing the same information), and concurrent (minimallyoverlapped speech and graphics).
