This article presents a computational model of the visual strategies involved in processing textual material. An experiment is presented in which participants performed different tasks on a multi-paragraph page (searching a target word, searching the most relevant paragraph according to a goal, memorizing paragraphs). The proposed model predicts eye movements based on 5 parameters. The weighting of parameters is determined for each task by means of a multidimensional comparison of participant and artificial scanpaths.
