Visualization of navigation information in www systems with support of mobility

Navigating through an information space is an activity, which takes place in many areas of information processing especially within the emerging area of world wide hyper-media systems like the World Wide Web. In this paper we focus on the visualization of the navigation process itself and o the information structures collected during navigation. Therefore, we are developing concepts and tools to handle a very large amount of distributed data, to select and to restrict these data with respects to client's needs, and to represent (visualize) the extracted information on the client's desk top or hand held machine.
