Zoomable User Interfaces (ZUIs) allow access to information-objects in a natural and visual-spatial way. Instead of navigating in abstract hierarchies and structures, the user can navigate in an infinite information landscape by zooming and panning. Informationobjects are therefore organized in space and scale, which allows the user to navigate analogue to the real world. If someone would like to access more information about an object in the real world they simply step closer to it. In a similar way, the knowledge about the location of objects can be compared to remembering where one has placed a certain book on the table. By transferring these concepts to the design of user interfaces it is made better use of the cognitive abilities of people, which have been specialized for these natural visual-spatial ways of navigation and orientation since many centuries. However this also implies some problems, which have to be considered. As in the real world, there is a certain danger of getting lost in such an infinite information landscape. The first part of this thesis will introduce the zoomable scatterplot ZuiScat and three different types of interaction- and navigation techniques. ZuiScat was especially developed for small screens, e.g. those used for Personal Digital Assistants (PDAs).Two experiments are presented, each including 24 participants, which analyse in which way those interaction techniques help to avoid problems in navigation and orientation. The results show, that users clearly ask for support as far as orientation and navigation are concerned and that the fisheye-distortion interaction technique seems to be the most promising one. This technique enlarges specific, user defined parts of the information space but allows staying orientated by distorting instead of discarding the context. An alternative to this approach would be an additional overview window, which allows for reorientation similar to an overview map. Taking into account the limited screen size which also complicates interaction, the second technique did not prove useful in the case of ZuiScat. Given different preconditions in terms of screen size and input devices it should nevertheless be considered as an alternative. The second part of this thesis deals with orientation and navigation in the real world. At first the basic theoretical foundations of Spatial Ability, Wayfinding and Cognitive Maps are introduced. The main navigation strategies are identified, which especially emphasize the relevance of Landmarks. Landmarks are described as distinctive objects or features of the environment, which can be linked to movement decisions. Furthermore they help in structuring the environment and support people in orientation matters. Therefore it can be said that they form the basis for route navigation and cognitive maps. Furthermore the neuronal findings regarding cognitive representation of space are presented. Special importance is assigned to the Place Cells in the Hippocampus, which somehow are thought to represent the environment in a cognitive map. However this field of research still has many questions to answer, which hopefully can be addressed in the next couple of years with the help of improved technological analysis possibilities. Some other topics that are addressed in this part are for example the structure of spatial memory. Many empirical studies support the hypothesis that our spatial environment is stored in hierarchies and that visual hierarchies embedded in an environment can have a large impact on navigation as well as on learning the environment. Another aspect is the measurement of navigation and orientation performance and the related problems.<br />The thesis closes with a summary of the topics presented and the effort to generate ideas for the design of zoomable user interfaces based on the psychological findings regarding orientation and navigation in the real world discussed in the second part. deposit-license deu Orientierung und Navigation in zoombaren Benutzerschnittstellen unter besonderer Berücksichtigung kognitions-psychologischer Erkenntnisse application/pdf Gerken, Jens 2006 2011-03-24T16:08:28Z Gerken, Jens 2011-03-24T16:08:28Z
