Based on experiments investigating the characteristics of path relations described by the german path prepositions (e.g. vorbei (past), entlang (along)), we are developping a computational method, which uses a 3D model of the environment, to find an appropriate path relation for a given situation. In addition we want to visualize path relations while presenting the adressee a virtual journey through the environment. The experiment rose evidence that there are protoypical characteristics of trajectories for different path relations depending on the reference object's shape. Reference objects are apparently 'attracting' or 'bending' the path taken by the moving objects and as in reality, where people tend to cut corners, the trajectories for example bend smoothly around the reference objects. Our idea is to let the reference object attract the trajectories used in the progression of visualizing the path. The trajectories are modified depending of the object's shape. Parameters such as strength and decay can be adjusted in order to approximate the modified trajectories to the prototypical trajectories form the experiment. Our hypothesis is that the modified trajectories visualize the different characteristics of the path relations most adequately by adhering to the prototypical path as far as possible
