Using fisheye for navigation on small displays

In this paper we present a solution to the problem of visualising large amount of hi- erarchical information structures on small computer screens. Our solution has been implemented as a prototype for mobile use on a hand-held computer using Microsoft Pocket PC with a screen size of 240x320 pixels. The prototype uses the same in- formation as service engineers use on stationary computers. The visualisation tech- nique we used for displaying information is based on fisheye technique, which we have found functional on small displays. The prototype is domain independent; the information is easily interchangeable. A consequence of the result presented here is that the possibility of using hand-held computers in different types of contexts in- creases.
