Eye-tracking in 3D visualization

The use of computer-generated perspective views, often named as 3D maps, is growing. These terrain visualizations should be more under-standable for users without cartographic education, which are not familiar with contour lines.
Perspective perception of a generalized and symbolized geographic space offers often a better understanding of spatial coherences. 3D maps could be seen as a supporting complement of classic orthogonal maps.
Many inexperienced map users have troubles to read 2D topographic maps that typically depict landscape features with contour lines, shaded relief and height points. To help these users, cartographers have increasingly turned to 3D perspective maps, which allow users to more easily visualize three-dimensional landscapes.
Several studies focused on finding user preferences of different visualization of terrain were done so far. Most of them used questionnaire as the main evaluation tool. However, several another approaches of the research on user perception and evaluation of the applicability and effectiveness of maps exist. Among methods of so called usability studies the eye-tracking belongs.
