| In this thesis, visual techniques for the display of uncertainty are studied. Four new uncertainty visualization techniques, namely, cylinder and cone glyphs, anti-aliasing, and four-point glyphs, are presented. Four existing approaches that were previously proposed by others for uncertainty visualization, namely ball glyphs, arrow glyphs, color mapping, and transparency, are also considered. A study of the techniques' usability is also presented. The usability study focuses on determining the effectiveness of the new and existing uncertainty visualization techniques. |
