The Impact of Visual Suggestiveness on Noticing Changes by a user of the Animated Map

Paweł Cybulski

Abstract

The thesis focused on examining the influence of visual suggestiveness on noticing extreme values of a geographical phenomenon by users of the animated maps. The author had taken into consideration the influence of spatial distribution of features on the map on noticing the extremes using two spatial models – concentrated and dispersed. For the needs of the experiment with 150 participants 15 animated maps had been designed. Two kinds of visual suggestiveness had been used. First was using simultaneous modification of two visual variables – color and size. Second was using simultaneous modification of two dynamic variables – order and scene duration. In the thesis author had shown theoretical basis of mapping methods with an animated technology, kinds of visual suggestiveness used in a visualization, reasons for change blindness and methods of its testing. The author had proposed own framework which consist five steps. Results shown that it is easier for the users to notice extreme values when location of phenomenon is dispersed. Furthermore visual suggestiveness using simultaneous modification of color and size positively reduce issue of noticing extreme values on animated map.
