The dynamic systems approach to the design of continuous interaction interfaces allows to simulate and use analytical tools to analyse the behaviour and stability of the controlled system alone and when it is coupled with a manual control model of user behaviour and calibrate and tune the parameters of the system before the actual implementation. In this talk we provide a dynamic systems interpretation of the coupling of internal states involved in speed-dependent automatic zooming, and test our implementation on a text browser on a Pocket PC instrumented with a tilt sensor. We illustrate experimental results of the use of the proposed coupled navigation and zooming interface with classical scroll and zoom alternatives. Furthermore, it is shown that browsing and targeting can be facilitated by using a model-based sonification approach to generate audio/vibrotactile feedback about document structure, in the proposed interface for a text-browser.
