Abstract: Designing visualizations of spatial data and 3D terrain is challenging. Usually the designer has to focus on selected relevant aspects of the data, emphasize them, and attenuate less relevant information. Yet, it is not clear upfront if design decisions with respect to emphasis lead to the desired result. Conducting user studies is often infeasible due to their high costs. We propose to utilize saliency maps early in the design phase to help designers assess their visualizations. Saliency maps provide information about the uniqueness of visual features in an images and hence can predict which part of a visualization is likely to attract the user's attention. Our approach is to compute saliency maps in real-time and show them alongside the actual visualization. This provides designers with immediate feedback on the effectiveness of their design decisions.
