Adapting Spoken and Visual Output for a Pedestrian Navigation System, based on given Situational Statements

Abstract

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.
