Tilt-based Automatic Zooming and Scaling in Mobile Devices - a state-space implementation

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 an accelerometer.
The dynamic systems approach to the design of such continuous
interaction interfaces allows the incorporation of analytical tools and constructive
techniques from manual and automatic control theory. We illustrate experimental
results of the use of the proposed coupled navigation and zooming
interface with classical scroll and zoom alternatives.
