What eye-movements tell us about ratios and spatial proportions
Catherine Sophian, Martha E. Crosby · 2000
Complex computer interfaces often provide quantitative information which the user must integrate. For example a scroll bar gives information about position in a document. The user can adjust the scroll bar to maintain an appropriate ratio of the portion of the document displayed relative to the documents position. Users are often given icons to select, does the icon's proportionality influence their choice? The task of identifying two shapes that are geometrically similar, though different in size, is a proportional one, but also one in which spatial processing may be important. Our research examines ways in which spatial presentations of the data can facilitate the process of integrating quantitative information.
